Sep 9 16:09:33 24 sshd[2060]: Did not receive ident string from 192.168.1.2
I have a Linux firewall (B) running OpenSSH2.1.1p4, trying to connect from my
LAN win-NT (A) with secureCRT 3.1 client. I've connected before with no
problems, and I can still connect to external linux machine (C) with same
openSSH version. So computer (A) can connect to (C). (C) and (B) can connect
to each other (using openSSH's ssh command). It's just that (A) won't connect
to (B) anymore, and I get the above error.
Recently I re-installed the Linux version on (B), saving /home info. There
are no differences in /etc/ssh from before. I removed the contents of
secureCRT's directory HostKeyDatabase so that it would re-create. It did
so for (C), but no prompt for (B). No public or private keys have changed
between my 3 computers. (A) can telnet and ping (B) and surf the web. My
firewall rules and /etc/hosts.allow are correct.
sshd : ALL : allow
Sometimes the client gives me "disconnecting for error reason 2"
I can't find docs on what that means.
When using secureFX (ftp) from (A) to (B), I get...
"Attempt to connect to 192.168.1.2 failed. Unknown application error E0000001"

Sep 9 17:29:38 24 ftpd[2591]: FTP session closed
When I connect from (A) to (C), I get...
"Opening the channel was administratively prohibited. Bla, Bla."
Could the changing of the ISP's DHCP generated IP for (B) have invalidated
the keys ?
Any help is appreciated :)
Thanks... Dan.
