[TriLUG] sshd: select: bad file number

[jbrigman at nc.rr.com]

Solaris version is "9". I just now figured out the roundabout cause:

ssh -V shows:
SSH Version Sun_SSH_1.0, protocol versions 1.5/2.0.
causes the problem...

Sun_SSH_1.1, SSH protocols 1.5/2.0, OpenSSL 0x0090700f
fixes it...

I'm trying to figure out which patch to ssh did the trick.
