[solved] ssh: Could not resolve hostname.. Name or service

[davidstar58]

I'm trying to set up a ssh tunnel over the Internet to a forwarded port with this command

Code: Select all

ssh -L xxxx:localhost:xxxx someone@something.dyndns.org:xxxx

with the correct info for the X's and user@hostname:port when I try this I get

Code: Select all

Could not resolve  someone@something.dyndns.org:xxxx: Name or service not known

I can ping the IP without the port number but with the port number it gives this response

Code: Select all

ping: unknown host xxx.xxx.xxx.xxx:port

I can connect within my own LAN but if i try to goto WAN (the Internet ) it gives me the same error

I have tried this on two Linux machines

a gateway laptop running mint 10

and an abit nf7 running Ubuntu 10.4 LTS

they both have the same /etc/ssh/ssh_config file

I think it is a DNS problem but cant find an answer by searching goggle with

Code: Select all

Could not resolve  Name or service not known
or
Could not resolve host
or
 Name or service not known 

I hope i have provided enough detail to explain my problem I am sure it is simple but I can't figure it out so
any help would be greatly welcomed

Update

i just tried to log in via ssh to my remote computer running mint 10 with my windows box using putty and it works just fine
It looks like both routers are configured to work with ssh being port forwarded but Linux can't resolve the DNS
where would i go to change this

I found the solution or at least a work around

Code: Select all

ssh -p port# -L xxxx:localhost:xxxx someone@something.dyndns.org
