Cisco ASA: Accessing VPN networks using L2TP VPN

Jason Tramer Jason Tramer Profile: Jason Tramer

Troubleshooting this issue for a bit, user connects to a L2TP VPN presented by the ASA. They can connect to the inside network but not to a network connected to that ASA via IPSEC tunnel.

This is actually a simple fix and enter the command:

same-security-traffic permit intra-interface

This will allow the traffic to transverse the tunnel.

Windows 7: How to bypass Windows Firewall on a Public network

Jason Tramer Jason Tramer Profile: Jason Tramer

I absolutely loathe Windows firewall, it just never works the way I want it to and Windows 7 has an annoying “feature” where when you are on a unidentified network it considers it a public network where you can not disable Windows firewall.

90% of the time this occurs it’s because I am connected directly to a router or switch and want to use the TFP server software on my laptop to upload a new firmware image but Windows firewall never lets that work.

So here is the workaround:

Start, Run, secpol.msc

Then click on Network List Manager Policies and then select Unidentified Network Properties.

here you can change the location type to private or at the very least select “User can change location” so that you can select private network if you want.

I understand why Microsoft designs operating systems that by default think I am an untrustworthy idiot, but it still bugs me.

Lync Server 2010 “Insufficient access rights to perform the operation”

Jason Tramer Jason Tramer Profile: Jason Tramer

I just set up Lync Server 2010 for the first time. When trying to add my administrator account to Lync I get the following error:

Active Directory operations failed on <Server Name>.  You cannot retry this operation: “Insufficient access rights to perform the operation.

After doing some hunting this is apparently a known issue with administrator accounts but there is a workaround.

Turn Advanced Features on in AD Users and Computers, locate the user that is not working, select the security tab, click advanced and select “Include Inheritable Permissions from this object’s parent” on the user object you then be able to add them to the Lync Server.

ICMP redirect cache is empty

Jason Tramer Jason Tramer Profile: Jason Tramer

I was deploying a new Cisco 1921 router and couldn’t get an internet connection going.  I did a Show IP route and saw no routes (not even my static) and got the message “ICMP redirect cache is empty”. After double checking that IP routing was enabled (it was), I rebooted but had the same issue. I did a “debug ip routing static” and then removed and re-added my static route. I then got an error dealing with the routing database.

In the end I turn off routing with a “No IP routing” and then turned it right back on with “IP Routing” and that immediately resolved the issue. It was very weird though.

MAC App Store – Getting some app’s for free

Jason Tramer Jason Tramer Profile: Jason Tramer

Now I am not advocating piracy here, far from it, and I firmly believe you should pay for app’s that you use (beyond a trial grace period). This is however an interesting tale. It’s kind of hard to believe this was an oversight though.

Gmail wipes out 150,000 accounts

Jason Tramer Jason Tramer Profile: Jason Tramer

Thankfully I was not affected by this but this does teach an important lesson about having personal backups. The big push used to be to get stuff off your computer in case of failure but big cloud provider’s have issues too.

Android App’s on a Blackberry?

Jason Tramer Jason Tramer Profile: Jason Tramer

Industry rumour is that Blackberry is considering a move to allow android app’s on it’s next generation OS (QNX). If this sound’s like a move of desperation it is likely because it is exactly that. Blackberry is hemorrhaging market share and if they don’t do something quickly they will be going the way of the dinosaur. Blackberries biggest issue for a while has been a lack of app support so this move may work well for the,

We shall have to see

VM’s black screen after migration to hardware version 7

Jason Tramer Jason Tramer Profile: Jason Tramer

Had this issue recently with vSphere. I upgraded a VM to hardware version 7 and rebooted. It showed it rebooted but once it passed the windows splash screen it went to a black screen in the console. I was also unable to ping or RDP to the server. After rebooting it and finding the same thing, I booted into safe mode which worked ok. I wanted to reinstall VMWare tools but sadly Windows Installer does not work in Safe Mode.

I went into Device Manager and found a yellow exclamation on the NIC driver but the display driver showed fine (WDDM driver). I uninstalled and reinstalled both. The NIC driver reloaded as the same driver but showing no warning, the Display driver reloaded with a different driver, the VMWare SVGA II driver. After booting into normal Windows mode, everything was fine.

Quite the headache though
