All my machines use SSH port 24739, but when I try to login via SSH, I get “ssh: CONNECT TO HOST \* PORT 22: connection refused.” I found a similar question on [Open OnDemand Discourse](https://discourse.openondemand.org/t/change-login-ssh-port-in-cluster-config/2419), but it has no answer. I tried setting OOD\_SSH\_PORT=“24739” in `/etc/ood/config/apps/dashboard/env`

, but it didn’t work.

That configuration is for something different unfortunately. I would say to provide an ssh wrapper that can set the port.

```auto
[root@oodrk9dev tmp]# cat /usr/bin/ssh_wrapper.sh
#!/bin/bash

args="-o SendEnv=MY_ENV_VAR -p 24739"
echo "SSH Arguments: $args" >> /tmp/ssh_wrapper.log
exec /usr/bin/ssh "$args" "$@"

```

```auto
[root@oodrk9dev tmp]# cat /etc/ood/config/apps/shell/env 
OOD_SSHHOST_ALLOWLIST="sl-c[0-9][0-9][0-9][0-9]"
OOD_SSH_WRAPPER="/usr/bin/ssh_wrapper.sh"

```

These settings still did not work, and it continued to indicate that the connection was on port 22. Ultimately, it only took effect when I set `Host * Port 24739` in `/etc/ssh/ssh_config`.
