hi, i am using vpnc-0.5.3-13.svn457.fc15.x86_64 , it connects well to the cisco vpn , then i initiate a ssh session to the servers , when i issue command like pwd, ls or date everything seems to be working fine but when i issues command like ls -la the session freezes and terminates what could be the reason.

Try tweaking MTU settings:

eth0      Link encap:Ethernet  HWaddr 00:1F:16:36:49:A5  
          inet addr:XXX.XX.XXX.XX  Bcast:XXX.XX.XXX.XXX  Mask:XXX.XXX.XXX.XXX
          UP BROADCAST RUNNING MULTICAST  MTU:1500   <<<<<<<<<<<<

An example command would be like:

# ifconfig eth0 mtu 1300

And, if this solves your problem, then set the appropriate MTU in your /etc/sysconfig/network-scripts/ifcfg-eth0 as:

DEVICE=eth0
MTU=1250
