Since an upgrade (that didn't upgrade the SSH server, but I recall it started happening since then) my FC6 SSH server is acting weird.
A login takes FIFTY (50) seconds on a 4Mb/256Kb ADSL line. This never happened before. I check the logs with a tail -f /var/log/* and all I get is the AUTH success message after 20 seconds and the user prompt at 50 seconds.
How can I tell what's happening? Is is the system or the modem? I'm running FC6 with the 2.6.18-1.2798.fc6 i686 kernel, openssh-server-4.3p2-10 and the modem is a Draytek Vigor V2700G, with the QoS options off.
After login, it is fast - it's just the login wait is, well, odd. No CPU consuming jobs running.
