Re: Change SSH Port

It appears IBM has made some changes in V7R4 that has
killed the capability to change the port number for SSH.

I don't know of any firewall in the IBMi. My SSH server is
on the same LAN as the IBMi. I do have a firewall in my
router but that has nothing to do with this problem.

Is there a firewall on the IBMi that I don't know of?

IBM I as a client.
V7R3.

May also have to adjust your firewall rules.

Hi Paul,

Thank you for the reply...

When you change the sshd_config file are you using the IBMi as a server?

I am using the IBMi as a client.
This change doesn't work for me.
I did remove the # so it wasn't a comment.

I have also tried changing the file ssh_config I have also tried putting the
port number into ACS None of the changes work for me.

Thank you,

Gary

\QOpenSys\QIBM\UserData\SC1\OpenSSH\etc\sshd_config.

Example, (remarked out) changing SSH port from default of 22 to 202,
but only for this specific client.

# Host 52.1.9.237
# Port 202
# Host ec2-52-1-9-237.compute-1.amazonaws.com
# Port 202

I need to change the SSH port.

I have tried:
CALL QP2TERM
ssh '-T -p 23 gary@192.168.168.9'
ENDTCPSVR *SSHD
STRTCPSVR *SSHD

I have also tried:
Opening Access Client Solutions
Management
System Configurations
Selecting my IBMi
Selecting Edit
On the Connection tap changing ports- SSH connections Close ENDTCPSVR
*SSHD STRTCPSVR *SSHD

I try to run a file transfer and it says:
ssh: connect to host 192.168.1.9 port 22:

How can I change the port SSH uses?

Thanks,

Gary Kuznitz
