无法连接到远程计算机'ssh_exchange_identification：读取：连接被对等方重置'

Question

I have right to remote server, For some reason I have to give access to my tomcat user. But by mistake I had changed user and group to tomcat7 user by below command:

chown -R tomcat:tomcat /

Then I am not able to login my virtual box using ssh and filezilla. getting below error:

ssh root@hostname ssh_exchange_identification: read: Connection reset by peer

Answer 1

Ouch, if that chown cmd succeeded you must have been executing it as root and if so - I'm afraid you changed the owner and group for the entire filesystem - I don't think you can recover your system entirely anymore.

You might be able to (but don't keep your hopes up):

• ssh tomcat@hostname
• su -

This would give you a chance to salvage some stuff.

Don't reboot the system - it'll likely not come back up again.
