4. Shrew Soft Vpn Client For Mac

I use multiple VPN clients, depending on which customer I am supporting on which day. I regularly use the Cisco VPN Client, the Cisco AnyConnect VPN Client, and the built-in Native Cisco VPN Support on my Mac (I’m currently running Snow Leopard version 10.6.8.) However, a recent customer project led me to install the Shrew Soft VPN Client they supported so that I could access their network through their Netscreen firewall. (This client is a free IPsec client distributed under open source license, to get it to work in the Mac I needed to also install the LGPL Qt Framework and a TUN/TAP driver, but that is another story…)

Some time later, I found out that after installing the Shrew Soft Client, neither the Cisco VPN Client nor the built-in Native Cisco VPN Support would work on my Mac. The AnyConnect VPN Client still worked fine. Obviously it was time for some troubleshooting.

Background
As a first step, I rebooted my Mac, but the Cisco VPN Client was still unhappy – it could not initialize the IKE ports. From the VPN Client Log file I saw messages such as:

The console messages for the built-in Cisco VPN support were not as detailed, but also indicated an issue:

Shrew Soft Vpn Client Mac Os X

(On the Mac, you can find console messages using the console.app via Applications > Utilities > Console )

Ok, I removed the Shrew Soft VPN Client, the LGPL Qt Framework, and the TUN/TAP driver. I still got the same messages. Rebooted. I got the same messages. I removed and reloaded the Cisco VPN Client software. I got the same messages. Rebooted. I got the same messages.

Partial Work-around
I did find a partial work-around – if I added “UseLegacyIKEPort=0” at the end of the .pcf files, I could get the Cisco VPN Client to connect. Google mail client for mac. However, I still had issues with the built-in Native Cisco VPN Support.

Releasing Port 500
I decided that I really needed to release whatever was binding port 500 that IKE/ISAKMP was trying to use. Something was not completely cleaned out from my removal of the Shrew Soft VPN Client. I did try asking the IT Support desk for one of my customers (hey, I was having issues with the VPN to them), as well as the official Apple Support number about how to determine what program was binding a port, and how to release it. I got a couple hints from them, but also did a bunch of Google searches. Other folks had run into a similar binding issue, so I tried to put together the pieces.

By the way, Port 500 is mapped to ISAKMP by default on the Mac, you can see that based on the /etc/services file:

What worked for me to find the process using port 500 was a “list open files” command, and then kill the process with super user priviledges:

After I killed the iked process, I was able to run the Cisco VPN Client, and the built-in Native Cisco VPN Support.

Permanently Removing the Binding
If you recall, the problem persisted even when I rebooted the Mac previously. So the iked daemon was being called during the start up process. I needed to find and remove this daemon call as well. I started looking for likely processes in startup directories and found it pretty quickly:

I rebooted my Mac, and Best twitter client for windows. success! My three regularly used VPN clients (the Cisco VPN Client, the Cisco AnyConnect VPN Client, and the built-in Native Cisco VPN Support) all worked. If required, I am pretty sure I could re-install the Shrew Soft VPN Client, and manually kill the iked daemon as needed if I wanted to run other VPN clients.

I hope this explanation may help others with Cisco VPN Client issues.
