Basic Differences Between CAT5, CAT5E, CAT6, CAT6e, CAT6a Cables

Basic Difference Between CAT6,CAT6e and CAT6a Cables
Basic Difference Between CAT5 and CAT5E Cables

Category 5
Category 5 cabling transmits at a frequency of 100MHz. This provides a rated line speed of up to 100Mbit/s and a cable segment length of 100 meters maximum. Most Category 5 cables, were designed for earlier networks replacing cat 3, only used two twisted pairs of wires. However, older Category 5 cabling continues to make up the majority of the world’s network cabling infrastructure.

Category 5e
Category 5e was later introduced as an improved specification to the very popular Category 5 that replaced Cat 3. The improvement was in noise reduction. By reducing the noise and signal interference beyond Cat 5, Category 5e rated transfer speeds increased to 350 Mbit/s over 100 meters. The new 5e cabling standard however also required all the cabling to include four twisted pairs not just two like with Cat 5. All eight contacts has to be used. Cat 5e introduced and optimized encoding scheme that allows up to 50-meter lengths of Category 5e cable to provide at or near Gigabit Ethernet (1000BASE-T) speeds. This was during the era of the early stages of Gigabit

Category 6
Gigabit Ethernet (1000BASE-T) became mainstream and required new industry-standard cables capable of transmitting at a higher frequencies than Cat 5e to go beyond the 50 meter limitation. Cat 6e transmits at 250 MHz. The new Category 6 cable uses thicker-gauge wire to attain the higher frequencies, it has increased shielding, and more pair twists per inch to reduce signal noise and interference. The new tighter specifications introduced with Cat 6 cabling guarantee that 100-meter runs of Category 6 are capable of 1000 Mbit/s transfer speeds. As with 5e reducing the cable length can achieve higher speeds than the category types design goal so 10-Gigabit Ethernet speeds can be achieved when reducing cable lengths to less than 50 meters.

Category 6e
The limitation of 50 meters of 10Gugabit was over come with Category 6 Enhanced (6e). Cat 6e is an augmented specification designed to double transmission frequency of Cat 6 to 500 MHz. It has the more pair twists per inch as does Cat 6 but it's also wrapping Category 6 in grounded foil shielding, a full 10-Gigabit Ethernet speeds can be achieved without sacrificing the max cable length of 100 meters.

Category 6a
Category 6a (or Augmented Category 6) is defined at frequencies up to 500 MHz—twice that of Cat. 6 but he same as 6e. Because it is shielded, Cat 6a performs at improved specifications over 6 and 6e, in particular in the area of alien cross-talk when compared to Cat 6 UTP Cat 6 UTP exhibited high alien noise in high frequencies.6A. To reduce the noise, 6a EA specification (not EIA/TIA) require a new generation of connecting hardware that offers far superior performance. 6A connectors performs 3 dB better than a Cat 6a connector that conforms with the EIA/TIA specification. 3 dB equates to 100% increase of near-end cross-talk noise reduction.

Enable SSH on VMWare 5 ESXi

2011-12-06T04:10:00.000-08:00

How to Enable SSH Access on VMWare vSphere 5 ESXi

Enabling SSH remote access to the console of an esxi 5.0 vmware host server is the same as in ESXi 4.1 (not 4.0 and earlier). In 5.0 vmware vSphere ESXi and 4.1 vmware vSphere ESXi it can be accomplished using the vSphere client. With earlier versions, like enabling SSH on ESXi 4.0, it had to be done via the server console.

How to Enable SSH Access on VMWare 5 ESXi

Enable SSH for remote connections from the vSphere Client
perform the following short steps to enable access to the ESXi Shell using the vSphere Client:
- Logon to the up to date VSphere client
- Select from the list of hosts the ESXi host you want to configure and choose Configuration then -> Security profile
- From the Services section under Security Profile, select Properties
- Select the SSH option in Properties and choose Options
- Select Start to start SSH on the host.
- Repeat the process for each ESXi 5 host.

There is no global or farm-like setting that would allow you to do all your hosts at once. Perhaps that will come in the next version ESXi 6 .

XenApp 6 HP Universal Drivers with Session Printers

2011-12-03T04:01:00.000-08:00

XenApp 6 HP Universal Drivers with Session Printers

In a few words I can tell you that using HP Universal drivers with Xenapp 6 to create or add session printers to user's ICA session is not a good idea. The drivers corrupt very quickly. I was involved in a Citrix Xenapp 6 deployment, a small deployment, of six servers. The installation was fresh so there was no history to be brought into the mix and be factored in as a collateral cause. Xenapp was installed on 6 new virtual 2008 R2 servers (The virtual architecture was VMWare 4.1) . It was a new Citrix xenapp farm and the server 2008 R2 server had all the OS updates. The xenapp servers ha the following hotfixes:

The Citrix Online-Plugin was updated through the office to version 12 of the full plug-in. All desktops were XP. The goal was to add session printers through Citrix policies. What printers were added depended on the location the user was in. If they were in office location A they would get a certain number and type of printers. If they were in location B they would get another different set of printers and so on. The policy used the ip address of the client as the method to determine the location. That worked well. Session printer creation worked well in all tests before the app went live. Apparently, the one thing I can conclude is there was not enough load on the server to be an issue. Once the office had gone live with their published applications, within a week there very strange things happening. Printers that were not supposed to be part of the session were listed. Ghost or phantom printers that were in the session and did not belong could not even be printed to. The users would get access denied messages. The logs on the server were riddled with errors. Default printers were being set to these ghost or phantom printers and even when changed , they would just revert back. Then, there was no consistency either as to what "extra" printer would appear in the session at each login.
The problem was traced down to the HP Universal driver. Yes, it was the latest release from HP and yes all printers were on the supported printer list from Citrix.
The tool that was used to test the printer drivers was StressPrint. The driver was removed and re-installed. All seemed well for a few days and then the problem arose again. Of course this time the driver was removed and printer specific drivers were used.

IP SLA Monitor Example for Fail-over Survivability of ISP

Configure ASA to allow traceroute responses

The following link is to an IP SLA configuration on a Cisco router that does not use the monitor command option:

Cisco ISP Failover IP SLA Configuration Example

IP SLA Monitor Example for Fail-over Survivability of ISP

Cisco IP SLA MONITOR example configuration. The IP address have been changed but this is a working configuration I just recently implemented. This office, actually and remote office with warehouse, has a T1 line they wanted a custom application to use exclusively but also had a DSL that was connected to a Cisco ASA 5505 (it could have been a Cisco 5510 or other). The ASA was also on the same LAN. The idea was simple, if the T1 fails, use the DSL for the custom application to connect to an online database source and server.

There are two tracker objects in a tracker list. The list uses a boolean AND,

track 10 rtr 20 reachability --> a ping to a target ip address for which there is ONLY a single static route to use the T1. This differs wit hthe IP SLA MONITOR vs. the IP SLA (with no MONITOR option available. Here, we had to use RTR instead of specifying the ip SLA number itself))
track 11 interface Serial0/1/0:0 line-protocol --> Interface status

track 20 list boolean and --> boolean AND, boolean AND means all conditions conditions have to be true , almost seems redundant but TAC did it this way on another remote office router.

object 10 --> tracker 10 shown above
object 11 --> tracker 11 shown above

ip route 4.2.2.2 255.255.255.255 192.168.1.11 track 20 --> tracked main route
ip route 4.2.2.2 255.255.255.255 192.168.1.1 100 --> alternate route is used if T1 is down

ip sla monitor 20 --> referenced in tracker 10

type echo protocol ipIcmpEcho 8.8.8.8 source-interface GigabitEthernet0/1 --> had to use the interface as source, using the ip address did not work (another bug, perhaps) , there is an explicit static route that says any traffic for 8.8.8.8 use the T1 (there are several ways to do this and you should test them on your router to be sure you can from the IOS command line ping and try all source interfaces before building this line. You can create the router using the next hop router for the T1 connection, or the route can be built by specifying the interface to source the ping from such as S0/1/0:0 on this router, or source the ping from the "inside" interface) So if there is a problem with the T1 the pings will time out.

timeout 1000 --> max ping reply time allowed in milliseconds
threshold 2
tag 20
frequency 5 --> status is checked every five seconds

ip sla monitor schedule 20 life forever start-time now --> scheduler for monitor 20

You cannot log on to the console because the server is not synchronized with the database. Upgrade the server and then log on to the console

2010-02-10T09:39:00.000-08:00

"You cannot log on to the console because the server is not synchronized with the database. Upgrade the server and then log on to the console"

Symantec management server console problem. This problem arose from an upgrade that did not complete. the upgrade of Symantec's management console was to version 11.0.5. The installation went near the end but did not complete as it was looking for the old version's installation media that was not available.
When the management console was started and the attempt to login was made the message "You cannot log on to the console because the server is not synchronized with the database. Upgrade the server and then log on to the console " was displayed. The console would not open.
There was a solution or two available from Symantec. One of which was to change the account he services use to use the administrator account and not the Local System account. this did not help. Un-installing was not an option because that would cause all the clients to get un-managed because the database would be empty at the re-installation. Although someone with more knowledge or experience with manipulating the build-in Symantec database may be able to use the re-installation method. I opted for an undocumented approach and that was to rung the installation of the original version.

Symantec Management Server Console Problem

The source media was found since this problem first started and running the installation solved the problem and another surprising benefit was that the management console had completed the upgrade. Clicking about from within the management console showed that the version was the upgraded version of the software.

Hope this post helps someone out. Good luck.

Supporting Technology with Technology.: Enable 24 bit color in RDP for XP or 2003 Server

The inability to connect to an XP or windows 2003 server computer using RDP with a color depth higher than 16 bits is a default setting on the remote computer. It can be chanegd on the remote server or XP desktop. No reboot is required t osee the results of the change. A goup policy change on the remote computer or in a domain group policy object klink to the domain or an OU can be applied.

making the change to the local policy or to the domain policy will allow connections to with true color 24 bit rdp.

A pre-defined default limit on XP or windows 2003 server limits the color depth of RDP connections to 16 bit maximum. How to configure the "server side" of remote desktop to accept connections at 24-bit true color.

Windows 7, Vista, and server 2008 already allow higher that 24 bit color by default.

Get outlook web access OWA working without reboot on II6 Exchange 2003

2009-10-26T08:33:00.000-07:00

The system service with a process id of 4 on 2003 servers listens on port 80 and 443. I checked this with another 2003 exchange email server to be close to sure of that being correct. It too has the system service, not an IIS service, with process id of 4 listening on 80 and 443.

I changed the port the default web site uses on the problem outlook web acess (OWA) web server to 81, restarted the services. Still couldn't connect with localserver:81 but now telnetting to port 80 worked. Just get a blank line is displayed when telnetting to port 80 (II6) unlike smtp that sends some text. Before the change to 81 for the default web site, the error returned by telnetting to port 80 was "connection refused". Changed the IIS default web site back to 80 saved, restarted the IIS service again and the default page loads and the OWA page also loads. As of now, no reboot of the server is required. Hope the fix holds.

Could try this solution on other servers that have IIS not responding and of course leads to OWA not working. Don't know if the same solution applies to 2008 server with exchange 2007 or 2003 server with exchange 2007 but some varient of the steps might just do the same.

This exchange 2003 server's access via port 80 (default web browser port) was working fine then suddenly IIS and OWA stopped working. I've seen this all too often over the years and ussually meant the server had to be rebooted.

Disable IE Enhanced Security on 2008 Server

2009-07-19T06:41:00.000-07:00

Disable IE Enhanced Security on 2008 Server

Well, as with many other things, the method to remove the IE Enhanced Security Configuration from 2008 windows server has moved. It was once easily found in the familiar Add/Remove programs applet through control panel and clicking on windows components would reveal additional options installed by the the OS for specific functions or roles of the server to operate. Now, it's moved to server manager in Windows Server 2008.

Windows Server 2008 installs by default with the Internet Explorer Enhanced Security enabled. So if you noticed, the Add/Remove programs in Control Panel is no longer used for adding and removing any Microsoft windows Server operating components. For so many years it was in that location, found through control panel but now it has changed with the new face of Windows Server 2008 so we all need to get used to as we've done for many other changes.

Server Manager is now used for managing Server Components, mainly throught the Roles and Features nodes, but IE Enhanced security is not listed here either. Remove IE Enhanced

Security with Server Manager:

Start -> Administrative Tools -> Server Manager
The root node is highlighted, in the right column, under the Security Information heading, click Configure IE ESC
Disable IE ESC for Administrators and/or Users

Having the enhanced security applied to the browser by default on servers is a nice thing to have. Many of us however do use the browser on the server to find driver updates and other things we need to perform tasks on the server wicthout the extra security nag.

Disable with Script or Registry Edit:

There will be a need somewhere to disable the Enhanced security feature of Windows server 2008 by using a script based method for automation of the process or by manully making the edits in the registry. Disable 2008's enhanced security using a script or a direct manual registry edit is through a registry setting that the GUI modifies. Specifically the IEHardenAdmin and IEHardenUser, so you could use a simple script to modify this setting. Refer to the following TechNet Article for more information.

Error 0x8004010F Object Could Not Be Found Exchange 2007

2008-10-12T07:59:00.000-07:00

Error 0x8004010F ..."An object could not be found" occurs when you do a manual send receive (the error also occurs with automatic background send receive) in Outlook 2003 or 2007 with Exchange 2007. In this case it was Exchange 2007 with service pack 2 (Exchange 2007 SP2).

The complete error message reads as the following:

Task 'Microsoft Exchange Server' reported error
(0x8004010F): ' The operation failed. An object could not be found.'

The classic error notification window can be displayed by clicking on the bottom right corner of Outlook or Outlook may have been already configured to display send/receive status each time. In either case, this is what the user sees:

This message just blares out to the user who thinks their emails are not being sent and as you know some users can easily get rattled and panic. The emails are in fact being sent out at least in my case and the majority of cases. If they are now getting and sending emails with this error message then the problem may be worse than this post will be able to assist with. The user's desktop can send and receive email just fine but receive this message each and every time they click on the send/receive button.

There are tons of sites that suggest rebuilding address books and fixing rights and permissions and a whole slew of other things that just don't seem to help the problem out. After trying those I realized this was not the average problem and mainly because I was getting this 0x8004010F error message with exchange 2007 and their post were solutions aimed at Exchange 2003 or 2000. There are some things that are different in Exchange 2007 that should be remembered if one is to continue rolling out Exchange 2007 or willingly or unwillingly participate in troubleshooting issues on this new platform. Keep the autodiscover feature on the list of things to check when troubleshooting Exchange 2007 issues with Outlook 2007, Outlook 2003 and even with Outlook Web Access. I have included Outlook Web Access too because the dynamics of finding exchange servers has changed somewhat and so too have the SSL certs changed (maybe that will be another post).

Add an autodiscover.yourdomain.com entry into your DNS servers and your problem will most likely go away.

No Icons on XP Desktop

2008-09-28T15:22:00.000-07:00

No Icons on XP Desktop

If you have a desktop that seems to start up normally in that there are no Trojans or viruses infecting the system after you have just cleaned it using various cleaning programs you can find yourself with an XP desktop with no icons.

Although I have a post of the solution for no icons on XP desktop after cleaning a computer from malware here - Can't find explorer.exe or iexplore.exe when run from task manager. Malware such as Antivirus 2008, Antivirus XP, and others, can leave an Windows XP desktop in a state of cleanliness but those software miscreants but also in a state of no desktop icons.

The reason for this is that the infecting software puts in there hooks in a way that really alters the ways the XP home edition or the XP professional edition computers start up. That's what makes them so difficult to be cleaned. The registry location, which was very difficult to find and not so well known, has an incorrect "image" location for explorer. This registry key is a special key mainly for third party programs and explorer.exe should not be there at all. Just deleting the key makes gets the icons on an XP desktop show again.

Attachment.ashx Message when Opening Attachment in OWA Exchange 2007

2008-09-24T03:38:00.000-07:00

Message window hangs when trying to open or save attachment using Outlook Web Access (OWA) with Exchange 2007 on a Vista computer with IE7 (Internet Explorer 7).

Attachment.ashx Message when Opening Attachment in OWA Exchange 2007

I recently ran into a situation where all of the users in an Exchange 2007 organization environement were able to open attachemnts using Outlook Web Access (OWA) against Microsoft Exchange 2007 server without a problem except for a few.

One of the users that wasn't able to open, run, or save an attachment using OWA was getting a message that said:

Geting file information: attachment.ashx from mail.{servername}.com

The message included the flying paper from left to right - the usual animation seen when transfering files in explorer or downloading files with Internet Explorer. This messgae would be displayed but would never go away and of course the user could open, save or viewer the attachment through Outlook Web Access.

Well, if any of you encunter this problem and think there is something on the Exchange server that could fix the problem don't bother wasting your time or making any settings changes as the solution won't be found there. You've probably already drilled down and found some of the differences with the user's computer that isn't able to open attachments with Outlook Web Access and commonalities with those users that could view, save, or run attachments through OWA. If the trouble computer has another browser on it like FireFox, try that browser and you'll see that FF works and since it works, then the server or the users accoount in the domain has nothing to do with the problem.

If the problem user ... I mean the problem computer, is Vista with IE7 then the setting that is most likely causing the problem for you is the one located in the Security cetegory under the Advanced tab after clicking Tools > Internet Options from the Internet explorer menu bar.

Un-check the box next to the setting 'Do not save encrypted files to disk". Once un-checked and the option is saved, open a new browser window and then try to open or save the attachment in Outlook Web Access again, you'll probably have better results.

If the information contained in this post helped solve your problem, please post a comment saying so or link to this post from your blog or site so more people can find the answer more quickly.

Remote Support Software

For web based remote access and computer remote control for remote support, try remote support software that doesn't cost an arm or leg to purchase and use. The name brands have many bells and whistles but are over priced for basic remote access for desktop remote control on the web. Appliance based online computer remote support software solutions and tools tout lower cost because you own the box but you pay maintanence fees and for support that's almost as expesive as the original purchase.

Can't find explorer.exe or iexplore.exe when run from task manager

2008-08-26T17:01:00.000-07:00

Can't find explorer.exe or iexplore.exe when run from task manager on a Windows XP computer.

This is a post worth noting. A computer was brought to me after a support person had removed all kinds of trojans, malware and badware from the computer using various tools. The latest and widespreading of these has been Antivirus XP 2008 and Antivirus 2008. The aftermath of this was that the computer was clean but windows can't find explorer. There are many people who have and are still encountering this problem and all forum post that I found while trying to find an answer have not yielded an answer. they all result in the end with the person who is supposed to know this stuff posting to the forum telling the not so experienced person looking for help and advice to re-install XP.

I too have tried to find an answer as to why the explorer.exe file, although shown in the windows directory, could not run when started using Windows Task Manager or even when run using or through a command prompt. The file was there but it would not start when run.

This was a strange problem that started when a computer was infected with mal-ware, ad-ware and other Trojans and bad stuff that so many users manage to get themselves in trouble with. A common aftermath it seems after searching the web for an answer or running smitfraudfix. Although I didn't run this tool, other tools to remove root-kits and other bad software were executed and all the harmful software was removed. The problem now was, and that's when this computer was brought to me, was that explorer.exe would not start. The computer at login would just show a blank desktop. Nothing but the back ground with now icons or task bar. this was a curious problem and after running some tools myself saw that there was no harmful software remaining on the computer.

After trying to track down the cause of the problem by using the error message, I saw that no one had an answer for this problem and the only way some people were able to overcome the problem was to re-install XP pro. The people tried doing a repair install still had the problem or their re-installation efforts of XP failed because they hung up at the part when explorer has to start. A re-installation doesn't "clean out" the registry of erroneous things. It merely replaces system files and adds folders that may be missing (let's not forget it loads devices drivers too).

It turns out that the clue to this problem is not in the error message when run from task manager bu t the answer lies when explorer.exe is run from a command windows or prompt. The error for when explorer.exe is different than any other made up program name.

This is the common error message when a program that truly cannot be found is executed:

When you try to run explorer.exe, the message states that the program cannot be found or something close to that. It;s not the generic message of a truly mistyped, mis-spelled, or missong program. There is a little know regitry location where program "images" can be defined and that's where the problem was lcoated. One little registry setting in an obscure location was preventing explorer.exe from starting. Supposedly this same problem has been experienced by users with Internet Explorer too but I've not seen this one before. If you having problems with Internet Explorer not stating when the program is clearly installed, try this fix for it too.

To find the registry setting please go to this blog post and remember to link to both post and sites and bookmark us in your favorite online bookmarking/sharing sites like delicios, technorati, digg, and others.

Acronis Disk Director 10 - My Review and Opinion

2008-01-11T19:47:00.000-08:00

Acronis Disk Director 10

Acronis Disk Director Suite 10.0 combines several other previous Acronis disk management tools into a single solution:

Partition Manager allows you to move, resize, copy, merge, and split partitions without losing valuable data.
Boot Manager is a utility software to create a multi-boot environement. It allows you to install multiple operating systems on your computer PC.

Partition Recovery allows you to recover accidentally deleted or lost drive partitions.

Disk Editor is a repair tool for disk drives. It allows you to perform advanced hard disk operations, such as restoring boot records and hexadecimal editing.

I had the opportunity to actually see Acronis® Disk Director Suite 10.0 in action. It was simply amazing as I watched a partition get re-sized almost instantly. what would have taken several hours to complete by reinstalling the operating system then also installing the applications on the computer to get to the same point.

It was the easiest and most convenient partition manager and hard disk toolkit I've seen. I thought partition Magic was a great partitioning software, Acronis made partition magic look child like in it's ease of use and the way it did not falter at all.

With the creation of this suite of disk utilities, Acronis brings together the most popular boot disk manager, partition recovery tools, and disk management functions in one installation package. I thought it was a great product and would recommend it to anyone who needs to resize a partition and it could do a whole lot more.

Netgear Rangemax Router Series

2007-06-28T15:56:00.000-07:00

I recently installed one of Netgear's Rangemax routers in a home office. I was very impressed with the wireless distance and more importantly the signal strength the new RangeMax routers from Netgear achieved.

The home was not an average home office. Some of the node locations were behind several walls and even a cement wall. Now we all know that traditional sheet rocked walls degrade signal quality the least so seeing the signal pass strongly through those walls was no great achievement but even in this case, the was literally no loss at all. Through the concrete and plaster I had excellent signal strength on one of the desktops that was behind the combination.

The configuration was very much the same at other products of it's category but only found a dislike in the fact that when I made a change to the configuration, Internet access was hampered somewhat. This may have been a coincidental occurrence but it was noticeable. The change that was being done at the time was a DNS server address change for client of the DHCP server. Another thing that I found curious, but one I've seen on many other home networking products, was a change not "sticking" . What I mean by this is that when the change was applied to the router, again it was in the DHCP section and had to do with the ip address range for the scope, it didn't actually take. The page showed the change but when a computer on the network tried to get a new ip address it continued to get the old ip address.

This was a little disturbing and after wasting a little time trying and retrying to get a new address on the computer, I realized the problem was on the the router itself. I reapplied the settings even though as mentioned the page showed the address changes I made, and restarted. The changes applied and stayed as I wnated them this time and the computer received a new updated ip address from the router.

Aside from those really trivial events, the Rangemax 824v3 router worked very well and had some very nice throughput. It was noticeably better that the other (manufacturer will remain unnamed) router that it replaced. Wireless security was improved over older models too. It had my favorite combination of wireless security features of WPA, TKIP, AES - and they worked very well. The Netgear Rangemax wireless router also support URL content filtering and web site logging.

For a full list of features see Netgear's Rangemax page.
