openssh unix dev - Jun 2002 - [Bug 285] 3.3p1 on Linux 2.2.x doesn't accept connections

Disabling PrivSep (add "UsePrivilegeSeparation no" to sshd_config)
should get it
working on 2.2 kernels.

3.3p1 defaults PrivSep to on. Previous releases (that supported it) defaulted to
off.

Turn compression off in the server.

The issue is mmap() on Linux 2.2 kernel does not support any of the useful 
options in order to allow PrivSep and Compression at the same time.

Either disable privsep (like what dtucker@ said) or change 'Compression
yes'
to 'Compression no'.

There is a patch being worked out to straight some of this out.

OpenServer 5.0.x also rejects incoming connections.  The user will be prompted 
for their password, but the connection will close immediately after.  The fixes 
suggested (setting "UsePrivilegeSeparation" and/or
"Compression" to "no")
resolve the inability to connect, though.

Also found on Kernel 2.2.14-5.0 Red Hat 6.2 (Zoot).

I can't make Compression no work.  With UsePrivilegeSeparation No, it
doesn't
work either.

If neither "Compression no" nor "UsePrivilegeSeparation no"
work, are your host
keys in ssh1 format? It seems that the new ssh's doesn't understand ssh1
format
host keys. If you use ssh2-format rsa/dsa keys, does it work?

OpenSSH 3.4p1 fixed this problem.
Kernel 2.2.14-5.0 - Compression yes and UsePrivilegeSeparation yes work
Kernel 2.2.12-32 - Compression musr be disabled for UsePrivilegeSeparation to 
work.

I wanted to pass that along, I didn't know if that was "known" or
not.
