SSH Could not resolve hostname

[Joao Lacerda]

Hi friends,

Can maybe someone help with this question?

I am trying to connect to a ubuntu server 12.04, with ubuntu 12.10, from the terminal and that is the response.

Ssh 192.168.0.xxxxxxx
ssh: Could not resolve hostname 192.168.0.xxxxxx: Name or service not known

ssh username@192.168.0.xxxxxxxx
ssh: Could not resolve hostname 192.168.0.xxxxxx: Name or service not known

It have worked fine when both computers had ubuntu 12.04.

I can connect it with putty and also with remmina, using the same correct address , but not on the terminal. What I am doing wrong?

Any help will be high appreciated
Thanks in advance

João

did you change the real IP? it wouldn't matter if you showed it as those are internal private IP's and no one can do anything with them.

you should be entering

ssh username@192.168.0.3

or whatever the IP of the server is, it shouldn't have to resolve it's hostname as it's the IP.

It's hard to see since you are replacing everything with x's (there really is no need to hide a private LAN IP like 192.168.xxx.xxx) but it looks like you have too many fields - are you trying to append a specific port? e.g.

$ ssh 192.168.1.102:22
ssh: Could not resolve hostname 192.168.1.102:22: Name or service not known

If so try using the -p option instead e.g.

$ ssh -p 22 steeldriver@192.168.1.102

Thank you friend.

That have worked.

$ ssh -p 22 steeldriver@192.168.1.102

many thanks.

u don't need to specify the port if your ssh server is listening on the default port, which is 22.

And changing the port is not a huge issue unless you intend on forwarding the ssh connection outside of your lan

I am now facing the same problem, and even worse, I can ssh the server in the lan, but I can't ssh my server form the internet, my iptables is set as xxx.xxx.xxx.130:20022 to 192.168.0.200:22, but when I do this" ssh server@xxx.xxx.xxx.130:20022, it results the same error, but when I ssh the gateway, I can ssh the server through the lan IP, but not the internet IP, thanks for your reply in advance.
