SSH enabled but can't access

[racom]

I've enabled SSH on ESXi 5.1.0 host but I can't access it. No open port 22 is visible via nmap contrary to other host I can access. Is any other way how to enable SSH? I can't reboot the host in the moment.

Assuming same network config for both hosts, have you tried restarting SSH?

/etc/init.d/SSH restart

[racom]

Thanks for quick answer.

I've accessed local ESXi Shell and restarted /etc/init.d/SSH but no change.

I can't see sshd via "ps|grep ssh' as on other host. /var/run/inetd.conf looks the same:

# Remote shell access

ssh      stream   tcp   nowait   root   /usr/lib/vmware/openssh/bin/sshd       sshd ++group=host/vim/vimuser/terminal/ssh -i

ssh      stream   tcp6  nowait   root   /usr/lib/vmware/openssh/bin/sshd       sshd ++group=host/vim/vimuser/terminal/ssh -i

# VMware authentication daemon

authd   stream    tcp   nowait   root   /sbin/authd           authd

authd   stream    tcp6  nowait   root   /sbin/authd           authd

Check /etc/host.deny

and place # Any : Any and do

service sshd restart

service network restart

No /etc/host.deny file on both hosts. Not running sshd is the problem. I'm searching logs but no hit yet.

Just check whether 'lockdown mode' is enabled..

If lockdown mode is enabled,if you are trying to do ssh,it will show "Access Denied" message.

Is this what you are getting?

Lockdown mode is disabled on both hosts. I've enabled SSH on both of them but I can access and I can see sshd running only on one of them. /etc/init.d/SSH restart makes the same changes in /var/run/inetd.conf on both hosts but I can't find log messages about sshd restart.

[SatyS]

Is this host having any network connectivity issues?

Are you able to access the host through VIClient?

-SatyS

[racom]

No connectivity problem with this host. It's a part of two node HA cluster where other node loose connection and I can't reconnect it. I wanted to compare config files so I enabled SSH.

[SatyS]

Can you check whether the firewall is blocking ssh?

-SatyS

[racom]

No firewall. Not starting sshd is the reason. But I don't know why sshd doesn't start and I can't find error messages.

[SatyS · Accepted solution]

Hope you are enabling the ssh as mentioned below

Enable SSH and ESXi Shell for ESXi 5.1 host ~ VMware Arena

-SatyS

[racom]

Bingo! You were right. Hosts internal firewall was the reason. I can't change it via console but via using "old" vSphere Client. Thanks.

It looks like this setting blocks sshd to start. But no warning message

[SatyS]

Happy to hear your issue is resolved.
