Re: slow ssh login on a cygwin machine
Hi Corinna !

This kind of delay is often a result of the process trying to
access some remote filesystem.
How can I investigate this (is there something like "lsof" in Windows)?
If you're speaking about "process", do you mean the "sshd" process? And
what could be a reason for it to access any remote file system? My home
directory is on the hard drive, I surely use some remote file systems
sometimes (by opening file explorer and copying files), but I don't see
any reason for sshd to do the same.
Is there any explicit way to "unmount everything remote" in windows? I
close all the explorer windows, but of course it could be not enough.

What kind of "DNS problems" could it be? I disabled reverse DNS query
(if I correctly understand meaning of the option "UseDNS") and see "last
login from xxx.xxx.xxx.xxx" message now (where xxx are digits).
Oh, thanks! I was getting over-suspicious :)
That size is not overly surprising. The size of the lastlog file
depends on the highest uid used to login into the system. In your case
you seem have pretty large uids. Every uid slot in lastlog takes
276 bytes. So you had login attempts from a user with a uid 1615639.
