Today I got many problems with my Citrix 4.5 farm, by opening Presentation Server Console i got this error:
Error code 0 (0) occurred while attempting to execute ‘C:\Program Files\Java\jre1.5.0_11\bin\javaw.exe’ with working directory ‘C:\PROGRA~1\Citrix\ADMINI~1\ctxload.exe
In de Application Eventlog I receive MSI install errors by opening Presentation Server Console:

VMWare has made CDP (Cisco Discovery Protocol ) available to their host.
When you the CDP is running on router/switch where the physical network card is connected it provide information to both Network administrator and ESX admin about host name/network card. This information help when you are trying to figure out which network card on the host is connected to which physical switch
B|–set-cdp Set the CDP status for a given virtual switch.
To set pass one of “down”, “listen”, “advertise”, “both”
On this ESX host we got 3 vSwitches, you need to enable the CDP feature for each vSwitch like (putty or console):
[root@ESX-vm2 root]# esxcfg-vswitch -B both vSwitch0
[root@ESX-vm2 root]# esxcfg-vswitch -B both vSwitch1
[root@ESX-vm2 root]# esxcfg-vswitch -B both vSwitch2
Now in vCenter 2.5 you see the Configuration > Networking > vSwitches, in te little comment box you can click:

In the old versions of the asdm and ios it isn’t possible to disconnect via the gui.
Via a telnet session you can rebuild the tunnel, you do this at the following way:
- Login via telnet on your pix
- Type enable (en)
- Then login into the configure terminal (conf t)
- Then type clear isakmp sa
- After you done this the pix has disconnected the vpn tunnel
Will I was creating some network documentation I stumbled upon the Cisco Visio Stencils that were released by Cisco.
To download the Cisco Visio Stencils, go to: http://www.cisco.com/en/US/products/prod_visio_icon_list.html
Wij constateren performance issues op de WAN interface maar de oorzaak is niet duidelijk. Men klaagt over traag internet maar toch blijft het moeilijk om het e.e.a. uit te lezen waar en wie nou die bandbreedte weg trekt.
De applicatie Fireplotter kan d.m.v. SSH of Telnet een connectie opzetten naar je Cisco PIX/ASA
Na enige periode te hebben gelogged krijg je een beeld met wie / wat performance wegneemt van je bandbreedte.
Indien je meer wilt weten over een bepaald protocol waar je veer verkeer over ziet lopen kan je op het protocol dubbelkikken, vervolgens krijg je te zien welke commincatie naar [destination] gaat:
In folder C:\Documents and Settings\Administrator\Application Data\FirePlotter\ staan logbestanden aangemaakt door Fireplotter. Denk aan connectie logs en firewall configuratie.

Kan zijn, bijvoorbeeld vandaag in het geval van bij een klant, dat de Cisco VPN niet meer werkt met de melding “authentication failed”.
Na controle van de PIX alsmede de server blijkt dat op de server de Internet Authentication Service was gestopt.
Dit problem zal zich vaker kunnen voordoen omdat het ontstaat na een security update van Microsoft:
DNS security update 953230 (MS08-037) http://support.microsoft.com/kb/956189
Oplossing is een aanpassing in het register:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters
Daar de key ReservedPorts aanpassen door de poorten van IAS toe te voegen:
1645-1646
1812-1813

Today i found a website where you can decrypt a cisco secret 7 password, this site is very handy when you lost your password but you still have the startup/running config.
Check the following site: http://users.skynet.be/glu/ciscopw.htm
Last week I’ve switched on tunneling on a Cisco ASA 5505, searched some additional necessary information which looks useful to share.
Find below a synoptic document of how to step by step turn on Split Tunneling on Cisco PIX/ASA for:
ASA 7.x with Adaptive Security Device Manager (ASDM) 5.x
ASA 8.x with Adaptive Security Device Manager (ASDM) 6.x
ASA 7.x and later via CLI
PIX 6.x through the CLI
