JHU uses Cisco VPN for outside connections to the university network. Unfortunately, this requires using Cisco’s VPN client, which is not really available for free download on the internet at large. Normally when I have a problem, I just re-install it, but the current version provided by Hopkins refuses to install on 10.5.3, citing a wrong O.S. version number. “Must be 10.4 or greater.” So 10.5 !>= 10.4? Anyway, what’s the problem I was trying to fix?
After upgrading my workstation from 10.5.2 to 10.5.3, the VPN client refused to load with a message about “Client error 51”, saying it couldn’t find the VPN service. This may be related to my use of an external USB wifi adapter, but it was never a problem in 10.5.2. Regardless, I found that restarting the VPN service fixed the problem. As an administrative user, I had to run this:
sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart
Now everything works fine.
