Public bug reported: I needed to connect to a Cisco VPN. I imported a pcf file, but after that the VPN failed. After testing with the vpnc commandline client it seems that the VPN concentrator is configured for 1DES and that vpnc disables that by default (which is good).
The error from vpnc ------------------------------------------------ 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 ------------------------------------------------ The setting as described in the manpage. ------------------------------------------------ --enable-1des enables weak single DES encryption conf-variable: Enable Single DES ------------------------------------------------ After setting the option to enable single DES the VPN worked. Then I went to the network manager settings: VPN->Advanced->Encryption Method and I changed it to 'Weak'. Then it VPN worked. What I expect if I connect to a 1DES Cisco VPN with the default settings is: - NetworkManager detects that the encryption method doesn't match and gives an error like "Encryption method mismatch: Local=Strong Remote=Weak, Go to advanced settings to change it" (Or a warning like "Remote VPN is configured for weak encryption: Continue or Abort?") ** Affects: network-manager-vpnc (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1190886 Title: VPN fails if remote uses DES To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-vpnc/+bug/1190886/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
