Public bug reported: Binary package hint: ppp
When I log on to a certain VPN of type "Microsoft VPN (PPTP)", the connection is always dropped after some time. It turns out that this happens when my computer sends a GRE-encapsulated PPP packet with a payload length of 1417. The MTU of the network interface ppp0 is 1412. I believe the VPN gateway accepts packets with a payload length up to 1416. (How can I verify that?) I am not sure whether pptp or pppd is the culprit here, but I suspect pppd. This looks like an off-by-one error. Does anyone know why this might happen? Any pointers where I might look? Is there any information I can provide you with? I am using Ubuntu 8.04 "hardy heron" with ppp 2.4.4rel-9ubuntu2. ** Affects: ppp (Ubuntu) Importance: Undecided Status: New -- pppd sends packets exceeding MTU https://bugs.launchpad.net/bugs/317567 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
