Solaris - Cisco router connectivity

Hello Experts,

My doubt is: Is it possible to connent a Solaris machine (with SSH enabled) to a Cisco router through SSH connection?

I don't know how to configure SSH Server/Client in Cisco router. But incase if its enabled, is it possible to connect to them from a Solaris machine ?

Here in the given below example, I'm able to telnet to a cisco router (IP: 157.95.25.4) but not SSH. Is there any different syntax for SSH to network devices?  I assume that in Cisco router SSH access must be always available along with Telnet as it is more secured.

[root@just root]# ps -ef|grep sshd
root      1733     1  0 Nov10 ?        00:00:01 /usr/sbin/sshd               <-- SSH is running
root      5168  5099  0 01:07 pts/0    00:00:00 grep sshd
[root@just root]# ssh 157.95.25.4                                                  <-- SSH to Cisco router, connection refused
ssh: connect to host 157.95.25.4 port 22: Connection refused
[root@just root]# telnet 157.95.25.4                                               <-- Telnet works  
Trying 157.95.25.4...
Connected to 157.95.25.4 (157.95.25.4).
Escape character is '^]'.

User Access Verification

Username: Connection closed by foreign host.
[root@just root]# ssh 172.16.2.19                                               <-- SSH to other solaris machine works.
The authenticity of host '172.16.2.19 (172.16.2.19)' can't be established.
RSA key fingerprint is 76:f6:d4:0b:ea:34:05:e5:65:76:8d:7a:78:a6:83:d2.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '172.16.2.19' (RSA) to the list of known hosts.
root@172.16.2.19's password:


I would appreciate if you could respond me at the earliest since it is very urgent for me.



Thanks,
Ashok

Some older Cisco products have an SSH server that is limited to SSH v1. Check the Cisco config/docs and make sure of what SSH version the server component is using, and, if necessary, supply the appropriate flags to your SSH client invocation.

Also, the user ID has to match. I don't think the SSH server in the Cisco IOS environment recognizes "root" as a valid user ID in the default configuration. So, again, check the docs and config to determine the appropriate user ID, and if needed supply that via command-line options when invoking the SSH client.
