RE: openssh sshd slow login

["Michael Erdely" <cygwin at cygwin dot com>]

Interesting...

I just re-installed Cygwin (I had deleted C:\Cygwin, all Cygwin-related
reg keys) and installed the full-blown package.  This time, here are the
only modifications I made:
1. ssh-host-config -y
2. chown 544 /etc/*
3. chown system.system /etc/ssh_host*_key
4. ssh-user-config -y -p ''
5. Edited /etc/sshd_config to allow password auth.
6. echo Hello>/etc/motd
7. Edited /etc/profile to include "date" at the top.
8. chmod og-w ~/.ssh
9. ssh localhost

I was instantly shown the motd ("Hello"), the date was displayed, then I
was given a prompt.

The _ONLY_ other change I made was in the Network Identification set up
for this Win2k SP1 Server which is a DNS server and _its_ defined DNS
server.  I added my domain name to the "Primary DNS suffix of this
computer".

So, after not having that long login time, I decided to configure my
/etc/profile (adding alias, customizing PS1, setting up a .input file to
ignore case on tab completion), modify the /etc/passwd (make usernames
lowercase, delete un-needed accounts) and /etc/group (make groups
lowercase, delete un-needed accounts) and run my script that changes
permissions on all of the files (removes og's write permissions, makes
544.544 owner of everything, then makes each user owner of his/her home
directory in /home).

I've rebooted several times and the problem does not seem to reappear.

Conclusion: it might have been a name resolution problem. By adding my
domain name to "Primary DNS suffix of this computer", cygwin/sshd/bash
was able to more quickly figure out it's own name (and/or the name of
the connecting machine).

Not for me.

Path=C:\Perl\bin\;C:\WINNT\system32;C:\WINNT;C:\WINNT\System32\Wbem;C:\C
ygwin\bin

I'm re-installing right now.  I can provide a cygcheck if you'd like.

BTW: The C:\Perl is ActiveState's ActivePerl.

That's not by chance related to having net shares in $PATH or
something similar, perhaps?
