Thanks everyone for the feedback on the OpenSSH hang. I'm going to ask the customer to review mtu in their configuration first to see if they can find a problem. Also, if their host OS is windows there are some things suggested to check, but I don't think it is windows. If it ever happens again I'll try to investigate more as suggested by Darren before we interrupt it. steve On Sun, Nov 10, 2019 at 5:29 AM Philipp Marek <philipp@xxxxxxxxxxxxx> wrote: > ISTR that I've read about some bugs with packet traversal through VM NAT > setups. > It was something about the RST packet triggering NAT destruction but not > being relayed further all the time (some race condition?!), that sounds > as if it fit the bill here. > > > https://forums.virtualbox.org/viewtopic.php?f=1&t=20579 comes close but > is a bit old... > > > You could try to use the TCP keepalive settings in SSH, and/or to reduce > the MTU size (as mentioned in another mail here already). > > > Else a few more setup details might help... > _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
