I'm surprised that it's happening for A records too given what I saw in the packet trace, but I expected to see this for AAAA. So your DNS (or resolver) is slow, and that's compounded by something in PAM making multiple trips to the well. The options I can think of are: * fix your DNS or resolver * make your resolver send only IPv4 requests * live with UseDNS=no * disable PAM. You also could try building OpenSSH with "configure --with-cflags=-DBROKEN_GETADDRINFO". This will force the use of the built-in getaddrinfo replacement that happens to speak only IPv4, but it probably won't help the PAM bits. I suspect this will make minimal difference though. -- Configure bugmail: https://bugzilla.mindrot.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
