connection not allowed from this server?

[Ivanner]

I'll keep it short:
We have a server on ISP X with RH 9.
We have a freshly installed server on ISP Y with RH Enterprise 3.
We have root password for both servers. Both servers have WHM 9.2.0.
We want to move all the accounts from ISP X to the new server on ISP Y.

This is the error we get:
The remote server XXX.XXX.XXX.XXX unexpectedly terminated the connection. (connection not allowed from this server?)

Anyone knows how to fix this ?

Please help...we're running out of time.

[Ivanner]

OK. Thanks everyone for NOT answering.

We figured out and here is the answer so if somebody runs into the same problem knows how to fix it.

SSH port on Server X was set to a non-standard port. The move script uses SSH to copy all accounts. We changed back the SSH port to default and everything worked like a charm.

I hope this helps somebody else.

Thank you so much, Ivanner!

Hello,

He was using some another port instead of 22, like 3145 or any other. So he edit the file and find out the port.

If you want to change the port; please use vi editor or any other editors

[boyforeigner]

looks like the problem is not wrong port, because i can copy fine from others server, just from one that I can't. So look like this one is blocked, and i get this error:

Packaging the account... The remote server xx.xxx.xxx.xx unexpectedly terminated the connection. (wrong port or connection not allowed from this server?)Done

Hello,

How did you try to connect ?. Did you try to connect user as root?
May be the remote server using any other port instead of 22 or the remote system doesn't allow the "root" to direct login.

Let me know the status.

Also check out the /root/.ssh/known_hosts at the server you are trying to copy from...and verify the key.
