ssh woes

[pressman57]

Hi all. I'm having a problem getting any kind of
connectivity between a PC running Mandrake 10.1
and a PPC running YDL2.3 through a Linksys router.

I installed sshd, wu-ftp and webmin on the Mac and
have sucessfully started the services on the correct
ports, I think:

[root@localhost greg]# netstat -lpn
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program
name
tcp 0 0 0.0.0.0:6000 0.0.0.0:* LISTEN 837/X
tcp 0 0 0.0.0.0:10000 0.0.0.0:* LISTEN 773/perl
tcp 0 0 0.0.0.0:21 0.0.0.0:* LISTEN 1016/ftpd:
acceptin
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 580/sshd
tcp 0 0 0.0.0.0:631 0.0.0.0:* LISTEN 718/cupsd
udp 0 0 0.0.0.0:776 0.0.0.0:* 600/xinetd
udp 0 0 0.0.0.0:10000 0.0.0.0:* 773/perl
udp 0 0 0.0.0.0:631 0.0.0.0:* 718/cupsd

But when I try to either ssh or ftp into the Mac from the PC
I get an error saying the connection was refused. According to
webmin I have no firewall configured, and have tried stopping
iptables to no avail. Nothing unusual has showed up in
/var/log/messages that I can see. I had the server installation
of YDL2.2 running on the same machine (before the hard-drive
crapped out) and ssh worked, so I don't think it's a hardware
issue. One suggestion I found suggested adding the line
sshd:ALL to /etc/hosts.allow but that didn't work either.

I really have searched the lists on this one and can't find
any solution. Any help would be greatly appreciated.

Can you ssh to any of the boxes by using the IP address?
BTW, ssh uses port 22. cat /etc/services

[pressman57]

Actually that's the method I've been trying:

ssh -l greg xxx.xxx.x.xxx
or
ssh greg@xxx.xxx.x.xxx
give the same result

Can you ssh localhostfrom the mac?

[pressman57]

Yessir. If I do that I get a login prompt.

I just thought of something. Both hostnames are the same. Would changing one of them make a difference, and if so how does one do that?

And thank you for the reply

[garskoci]

Can you ping all of the boxes by IP? Is sshd running on the boxes?

[pressman57]

Yes, I can ping both ways without any packet loss.

[pressman57]

And sshd is running on the Mac, port 22.

[Modorf]

try nmap to determin which services are actually open.

nmap ipaddress

[garskoci]

ssh should be running on the other box too.

As I understand, you want to connect from your pc (linux
presumably) to the Mac. Then you should have a ssh server
in Mac and ssh client in linux. Then, the port in which the
server is accepting connection should be open to receive
connection. As I see, form the firewall configuration,
the port in which the server is accepting connection is 580
(was it 480?), which is not the default port. So I think you
should specically tell your client to try access that port:

try :
ssh -p ssh_port user@ip.add.of.mac

Hope this helps.

I think I figured it out. I stopped iptables from webmin and that opened up the port. Why it didn't work from the command line I don't know. Thanks for the replies.
