vpnc: peer selected (single) DES as "encryption" method

When you trying to vpnc and get following message

#vpnc abc

[root@inf1sysadm1 vpnc]# vpnc abc
vpnc: peer selected (single) DES as "encryption" method.
This algorithm is considered too weak today
If your vpn concentrator admin still insists on using DES
use the "--enable-1des" option



To resolve this simply use this command.

[root@inf1sysadm1 vpnc]# vpnc --enable-1des abc
VPNC started in background (pid: 9444)...


Hope this will work for you :)
