Problem with vpnc
Last modified: 2008-04-03 04:47:28 EDT
Description of problem:
version No. vpnc-0.3.3-13.fc6
This worked fine two weeks ago but now the following comes up when I try to make
a vpn connection:
/usr/sbin/vpnc: quick mode response rejected: INVALID_PAYLOAD_TYPE
this means the concentrator did not like what we had to offer.
Possible reasons are:
* concentrator configured to require a firewall
this locks out even Cisco clients on any platform expect windows
which is an obvious security improvment. There is no workaround (yet).
* concentrator configured to require IP compression
this is not yet supported by vpnc.
Note: the Cisco Concentrator Documentation recommends against using
compression, expect on low-bandwith (read: ISDN) links, because it
uses much CPU-resources on the concentrator
I found on google that somebody using ubuntu had a similar problem until they
recently upgraded their version of vpnc.
Also, I can still make the connection from a windows 2000 machine
Can you please try to recompile the vpnc src.rpm from Fedora development/7
whether it helps?
