Personally, I have found that VPNC works better than Cisco's own client. It should be part of your distribution. Try "yum install vpnc". You run a script against your Cisco vpn config file to convert it to vpnc format.
By the way, QuickBooks will run under Crossover Office. In fact, the company that builds and sells Crossover Office uses QuickBooks internally running under their own product.
Thanks very very much ! When I first started using the cisco client a few years back, all I could get from Cisco was the source and I had endless problems trying to get it to compile under core 3. After I finally solved all those problems and dependencies, the thing never would authenticate against this company’s concentrator. Their tech support didn’t give a rats patootie and didn’t want the hassle of trying to work with me to resolve whatever issue was causing the problem.
I just upgraded one of my servers that I also use as a desktop for a few things to Core 8 - I’ll get right on it and get rid of the Windoze POS !
