Shell Command for Getting IP Address?
Solution 1:
/sbin/ifconfig -a
Solution 2:
You can use:
/bin/ip addr
Solution 3:
If you have an internal address in use, checking
curl http://myip.dnsomatic.com
might be a good idea on unix shells.
Or, just plonk that URL into your browser.
If you get a different answer from the "ifconfig -a" result,
the ifconfig gave your internal address -- which will probably not work from outside.
Even if all seems fine, you could have a firewall in place that will disallow incoming ssh connections.
At which time you should try the port of interest from a browser on the machine at,
http://www.canyouseeme.org/
That will confirm connectivity through,
- external IP address (showing it to you on that page)
- NAT, Port Forwards
- Firewalls
Solution 4:
/bin/hostname -i
Solution 5:
curl icanhazip.com
tee hee!
