No connection after 'passwd' command

[hepter]

Hi,
It's not about the script, but I want to ask a post-access question.

After logging in I ran the 'passwd' command for ssh without paying attention but now I've lost access either way. I can no longer use telnet.

I tried the following commands;

ssh root@192.168.1.1
ssh: connect to host 192.168.1.1 port 22: Connection refused
-------------
telnet 192.168.1.1
Connecting To 192.168.1.1...
Could not open connection to the host, on port 23: Connect failed

Is there any way I can regain access?

Thanks
