Firewall issue

[Michael Sullivan]

I hope someone can help me.  I'm using Cygwin on an old PC with 1.2gig
hard drive and 24MB RAM (pathetic I know.)  I'm using the PC as a
holding area for backups so that I don't have to write the backups to CD
every day.  The network card in the PC is a Kingston Etherex card, and
it's not very widely supported on a Linux that fits on 1.2 gig with so
little RAM.  Anyway, I've hooked it up to my network and installed
Cygwin, though I don't think I have enough space for all of it.  I want
to be able to run sshd so that my server PC can copy its daily backups
over to the Cygwin PC, but every time I try to ssh from the server PC
over to Cygwin, I get a "Connection refused".  I'm not familiar with
Cygwin's firewall; I'm used to using iptables and there doesn't seem to
be an iptables package available on the Cygwin setup program.  How do I
fix this?

Hello,

I don't believe that Cygwin installs a firewall as default...

Cygwin has no firewall.  Please follow /usr/share/doc/Cygwin/openssh.README.
If that doesn't help, read and follow 
when contacting the list again about this issue.

If you're "used to using iptables" than you should know that
"Connection reset by peer" is an indication for a firewall.
"Connection refused" means simply "no ssh daemon" there.

Install and run sshd according to the Cygwin ssh readme.
