Hi.

I'd like to try and help you, but didn't quite understand what you were trying to explain... Could you try to provide more details?


kenneho

Have you got any firewall or tecp wrappers that is blocking the connection to ssh port?

can you post the IP address & netmask & default getway info for all the servers u are trying to connect i.e source & destination servers

also check wheather firewall & selinux are enabled

check wheather ssh service is active

check with mii-tool for proper connections

thx replies ,

no firewall is actived.

if I re-setup the ssh ( the normal procedure : ssh-keygen -t rsa , then copy to remote server , .... etc ) , the user can use ssh now , but I have hundreds of users , so I would like to ask except re-setup ssh for all users , what can i do ? thx

Did you mean to say: I have two servers which log into remotely to a third server.

Which server are you migrating? One of the first two or the third?

Look in the logs of the server after a relocated user tries to log in.

What do you mean by "the screen is hold"?

---

One thing to check is the permissions of the users' home directories or their .ssh directory or the .ssh/id_rsa file.
---
Also try logging in as a migrated user using "ssh -vv <username@host>". Post the result. Then check the log on the ssh server.
---
Do the users now have a new IP or domain name?
