Recently been on a CCNA course and apparently I ask waaay to many questions, so I have been given a “fun task” at work. We have quite a few switches, some of them have telnet enabled and others have SSH only. I am trying to figure out, how you would do a search against an IP or a range, whether they have port number 22 and/or 23 enabled?
Been searching, as one does, and found that plink, part of putty, are able to do that via powershell. As I have no skills in powershell or programming at all, I am a little over my head here. I was wondering if any of you might have a clue OR a better idea of achieving this task?
What I am hoping for:
able to use an IP range(s) rather than single IP’s.
ask for ports. ie 22 (SSH) and 23 (telnet).
Return an answer if the specific port is using port 23. ie. “Port 23 is open and password is sent in plain text”.
Return an answer if the specific port is using port 22. ie. “Port 22 is open and I am protected, using SSH”.
4.1. If possible, if both ports are open write something like. port 22 and 23 are both open.
Return that answer to an output file ie. Excel or something similar.
Being lazy, as one is, I would like to do this with minimum effort possible.
Looking forward hearing what you have for me?
