Hello:
Up until recently, I have been able to scp/ssh from my F16 box to my WinXP under cygwin without problem. Today, it appears that isn't the case.
Last "yum update" was 29jul12. Cygwin hasn't changed in months (once I have something that works I am loathe to update as I don't really get it well enough to ride a more bleeding edge)
I can ping both ways but can only scp/ssh from cygwin to F16 (though I don't use it, I tested telnet and got the same results). I swapped in my "log all problems" version of iptables on the F16 box and can see that it is logging errors and I see the following:

I did a google but this information is pretty much Greek to me so I didn't find anything because I didn't understand how to find something
My big question is "any suggestions?" There is a second minor issue about is there a way to force iptables to immediately flush a message to the log file as I had to wait about 10 minutes to get something.
When you say you "tested" telnet, did you mean you did something like this?
telnet cyghost 22 for checking the ssh connection? Did you get any errors....or did it just hang?
FWIW, the log messages just mean netbios packets are being blocked.
Ed:
Thanks for the prompt reply. I got the same message for telnet as I did
for ssh and scp. And, as I re-read my email, I managed to not report
that message (I actually did, but that was before I got a log message
and it apparently got wiped out when I reworded from "nothing in
/var/log/messages" to "I got something".
I just powered my F16 box back on and did a ssh/telnet/scp. The message is
+++
[ssh,scp,telnet]: connect to host krazy port 22: Connection refused
