Thread: SSH Between Ubuntu and OS X

i trying use ssh between ubuntu box , macbook. i'm new ssh.

able log ubuntu machine macbook fine command:

ssh user@ipaddress

messed around it, sent photo myself scp, looked through files, etc.

when reverse process though, i'm not able access macbook ubuntu machine. tried ssh -v , seems "port 22" blocking me doing it.

of course googled "open port 22 mac" find out how it, ended finding quite few discussions dangers of having port 22 open because it's first place people see if machine there, after they'll try guess pw using dict or etc.

have 3 questions:

1. how open port 22 cl on mac? (if happens know)

2. should open it, or there way safely?

3. if it's concern open on mac, mean it's open on ubuntu box because can ssh it, , should close it?

simply opening port 22 not far. have ssh client on mac , ssh ubuntu mac need ssh server. don't have mac, can't there.

concerning safety of opening port 22. read true point. if on home network, you'll have router blocking access internal network internet. , unless forward port 22 router mac or ubuntu box, needn't worry it.

it's different of course if connect untrusted wireless access point. strong password main defense strategy. configure ssh server use port number other 22. there more ways of hardening ssh server. beyond scope of post.
