GNU screen ?
 

hi, guys
i am very new to screen program, i would appreciate any help to get it running.
i am trying to user screen program with either telnet or ssh to run commands without disconnecting from my eth0
when i try "screen" command and /sbin/ifconfig eth0 down , i get disconnected from my session , i think when unsing screen i should stay connected .
i would love to know the procedures how to get it running and working, when i type screen it only creates .screen and i do not seen .screenrc .
by the way , i am using redhat 9.

thanks to everybody.

to run screen I use something like this
I have the screen installed on the server machine.

screen uses commands that are of the form Ctrl+A char

so I login to the server and run screen
now i start working and when Its time to go you can either leave it like that or if say you have to disconnect then use the command Ctrl+A d
which will detach the screen you are working. now you can close your telnet and go home peacefully.

Once I reach home you telnet again to the server and use screen -x and bingo you are back
to the old screen,

you can get help anytime when you are on screen using Ctrl+A ?

Ctrl + A c gives you a new tem to work on
Ctrl + A A goes to the last screen you worked on
Ctrl + A space will cycle among the screen
Ctrl + A " will show a list of the current screens
Ctrl + A d will detach
Ctrl + A [ will allow you to scroll - use the arrows to navigate
in scrolling mode use space to start copying a buffer another space will end copying
Ctrl + A ] will paste

read the info docs for a good overview
info screen
pinfo screen should give you what you need.

thanks
 

thanks for your help .
i am trying something different , which is the following:
suppose i telnet to the machine , and i execute sreen command , then run /sbin/ifdown eth0 (will bring the network down ) but i want to be still connected to the shell it means that i will be able to run commands to the shell even that eth0 is disconnected and then type /sbin/ifup eth0 and that will bring the ethernet eth0 up again .
beleive i saw that and tried , worked perfectly .

thanks

i dont understand how that is possible. because when you login to a machine and bring its eth0 down then it means the telnet also is down .

one psosible thing that could have happend is
the machine had 2 cards when you telnet it was using eth1 and you shutdown the eth0 device. eth1 was still up. screen has nothing to do with networking.
