SSH Windows Client Cannot Connect to HP-UX SSH Client/Server

[RIACDC]

Gentleman,

Anvil corrected my issue with using secure shell to login into an HP-UX client to server and reverse. I can successfully login using ssh fom HP-UX client to HP-UX Server, but I new issue has surfaced.

I just attempted to login into this server using a windows based ssh client, but this client fails to connect to the server. Is there a similiar command set to faciliate windows ssh client to HP-UX server connectivity. My windows client can ping my HP-UX ssh server.

Another thread by you. Just because windows system can ping to hp-ux system does not mean that ssh/telnet will work. How you have configured the ssh client on windows. Which client?? What is the method that you use to authenticate ssh??

Do you see anything in syslog?

Again, on hp-ux server stop sshd and start it as follows.
/usr/sbin/sshd -ddd
Now try connecting to hp-ux server using ssh client. Post sshd log.

Please provide the ssh client you are using on the windows side since there are some that do not support ssh2.
Also, were you asked to accept the public key when you tried to connect ?

Please check the following

1. Check whether your windows client connect to correct port where SSHD runs. Default is port 22.

2. Ensure the authentication type you selected in windows client is supported by SSH server.

3. If you use public key, check that your key type is accepted by the server

4. Check for any DNS lookup problem

5. HP Secure Shell by default supports only SSH protocol version 2, check whether your client is configured to use protocol version 2

6. Did telnet works from your client?

8. Check whether your host is allowed to login. Server may have access lists.

7. Still have problems, send the server and client debug messages.

All the Best

If you have generated your key pair in Windows ex: putty keygen, the format is different from the unix format.

There are 2 comments line ( the first and last if I remember well) that have to be deleted and the windows generated key is not on a single line ( it has cr line feeds in it)you need to delete those too)in order for the key to be ONE single line.
