This is really a problem that I have had since I installed F21. It was
a clean install, not an update.
Anyway, when I connect to various servers that are setup for user/paswd
login, it is a while before I see the password prompt.
After working on the system for a while, the session is suddenly
unresponsive. I can ping the destination, but nothing in the ssh
session. Usually after some time (more than a minute) the session
resumes responding.
If I leave a session connected and move away from it, eventually I get a
"Write failed: Broken pipe"
All the systems I am connecting to are on other networks, so I am going
through a firewall that permits my ssh connections.
Any hints where to look? Wireshark is not showing me anything, but I
may just be using the wrong filters.
In my experience, a slow ssh password prompt is due to DNS lookup
issues--particularly reverse DNS (ipaddr-to-hostname) lookups. If the
remote machine is having trouble doing a reverse DNS lookup on your
client IP, then you just have to wait for the DNS to time out before you
get the password prompt.
As to why it slows down, could be any number of other things. Are you
on a VPN? Are you getting your IP via a DHCP server? Are you on a
broadband connection?
