[c-nsp] Cisco VPN Client - Linux

[Dave Breiland]

Has anyone else had success and/or issues running the Linux 4.6 client 
under a 2.6.10 kernel?  I am able to establish the vpn connection, and 
even ssh to a host on the other end.  However once anything more than a 
simple transfer (i.e. ls of a directory) causes the session to hang.  It 
doesn't seem to be an issue with the concentrator, as windows clients 
don't experience this issue. 

Both interfaces on the concentrator have the MTU set to 1500.  We have 
attempted to even manually set the linux clients to a 1500 MTU, but 
still no progress.

I am trying to deploy a VPN Concentrator 3005 which will have mostly 
linux users.  I was hoping to avoid using OpenSWAN or VPNC as I've read 
they require the plaintext password. 

Any thoughts or input would be appreciated.

Thanks,
Dave
