We've run into this weird AWS issue 3 times now in a week, never seen it before:
A Linux instance becomes unreachable via ssh from some ip addresses. If you try to ssh from those addresses, it just hangs, for ever, until to ctrl-c out of it. Yet you can ssh from other ip addresses without any problem. The ip addresses that work and that don't seem random, some are outside AWS, some inside, even on the same subnet. When we run in DEBUG3 mode, we see that the client sent it's key, while the server waits for the said key, and sits there waiting. The few similar issues (ssh hanging at key exchange) we found when googling were solved by changing MTU! The only resolution we have found so far is to stop/start the instance and get a new ip (tbh, we haven't tried to just reboot). Has anybody run into this? Any idea what's going on? -- Yves. _______________________________________________ Tech mailing list Tech@lists.lopsa.org https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
