Yesterday I faced an issue, where in I was unable to login into NGZ’s after kernel patching. Though the zlogin was working perfectly.
Initially I think the cause is ssh key, then I tried to login into the NGZ from the network, it was showing ssh connection refused.
I have checked the ssh services via zlogin. There were many services related to network which were not running including ssh. All services were depending on /system/sysidtool:net service which is in disbale mode. I tried to enable /system/sysidtool:net service but No luck.
