Some tests: Part of the output of command "ip link" :
On a 15.04 system, after connecting to the VPNC, it works nicely, without any workaround: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1412 qdisc pfifo_fast state UNKNOWN mode DEFAULT group default qlen 500 After connecting to VPNC on a machine upgraded to wily, it does NOT work: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN mode DEFAULT group default qlen 500 Entering command "ip li set mtu 1412 dev tun0" after the VPNC connection on a machine upgraded to wily, now it works: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1412 qdisc pfifo_fast state UNKNOWN mode DEFAULT group default qlen 500 Thus, it seems, for some reason, 1412 MTU is set in pre-wily systems when connected to vpnc, while it's not the case with wily, and needs a manual workaround? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1504435 Title: Cisco VPN does not work (connection hangs through vpnc) after upgaded to wily To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/vpnc/+bug/1504435/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
