port 22: no rote to host but in other computer it works!!!!! Please Help
hi to all know i have a very strange problem and i would like to ask is someone con halpe me please
1º the computer A a server with the Ip x.x.x.215(in the same room and network)
2º the computer B my computer with the ip x.x.x.224(in the same room and network)the COMPUTER WITH PROBLEM
3ºthe computer C of my friend (in the same room and network) ip x.x.x.225
when in my computer (computer B ) i try to connect to computer A the server by ssh it send this message
ssh: x.x.x.225 port 22: No route to host
fine i say the port 22 is not open in my computer B,but is open!!
also i think in the server A the port 22 is not,open but is open!!
i have say to my friend please connect to the server A and he say
i connect ok ,fine the machine A is up also i have verfied the ssh service is ok in the 3 computers
the first thing that i have think 'is a problem with iptables or rules '
if is a problem with this and my friend in computer C uses my IP(x.x.x.224) and he tray to connect via ssh he also will receive the same error
and i have restart your network service with mi ip x.x.x.224 thinking that he will have the same error and is a problem of IP
but NO!!! he can connect without problem and i have put again the IP x.x.x.225 to my friend
fine i think perhaps the cable?
i have take the cable of network of the computer of my friend C and i put it in my coputer B and also the same problem
i tray to connect from pc B to other computer perhaps if not connect to other computer the problem is other the network
but i can connect to other servers and the computer of my friend C
x.x.x.225 without problem
is in particular to x.x.x.215 that i can connect from my computer B specifically from my computer ,mmmmmmmm strange!!!!!
i can navigate in internet and see other pages in internet but the pages in x.x.x.215 i can not see nothing , no connection ssh and nothing
i tried to ping to x.x.x.215 and it say
Destination Host Unreachable
and the last thing that i have tray is to connect to computer A the server from computer C , and from the server A connect to my computer the B and didint see it say the same thing Destination Host Unreachable ,is like the two computer( A B) can't see trough the network
i have read a lot of information about this ,i have clean the know host archive,see the iptables,verify port 22,verify th ssh service but nothing , even know i dont know what can be because is specifically my computer even more not my ip ,my computer PLEASE HELP
