in few words I have 2 RH5 machines, i need to connect from one machine to another using ssh..everything is fine until i try to do it
When i am tryting to ssh user@host, i get after about minute connection timed out. The RSA key auterized keys are configured. entried in host file are added.
When i try to ping the host to which i am trying to connect everything seems to be fine. so i am trying to telnet ip port, says trying ip, then times out. OK i tracetour -n ip, and that is the place where i stack.
Okey its runing and listneing the posrt 22, but i may have spoken to realy about firewall, because i did not turn it off and i just assumed why would it be set up if its iternal server, but i probably should check if firewall is up, right? so question is how? and how can i check if firewall is blocking incoming connection?
[root@tlnpatl07 etc]# ssh -v email@example.com
OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug1: Connecting to tlnpamt01.gi.telenor.com [10.254.50.10] port 22.
debug1: connect to address 10.254.50.10 port 22: Connection timed out
ssh: connect to host tlnpamt01.gi.telenor.com port 22: Connection timed out
and yeah host is added in host file, and out put of third script
how can i check if there are devices between thous 2 machines?
did not quite understood that about other services, sorry!
well if you are asking this thats probably means you are not the network administrator there
you should contact them
about other services, i just wanted to see if other ports can be seen open or all of them filtered
most likely it is firewall issue somewhere as ping(icmp) worked for you, that means network connection is possible (of course if you pinged the right ip ^^)
how many interfaces the systems has?
ifconfig - will show you the active interfaces
route -n - will show you the routing table used by the system
you should then know which interface and then which gateway is used
who is responsible/can access that gateway?
so if you are only responsible for the 2 hosts you will need network admin assistance i believe
