Telnet question

[Anthony khan]

Hi,

I want to check telnet connectivity for all production boxes, Do anyone have an idea how to use telnet in a script or is there any other way to do it.

Thanks in advance

'netstat -a |grep telnet' on the server concerned will show if the telnet daemon is listening.

My all-time favorite monitoring program...

http://www.netsaint.org/

It will let you monitor any port on any number of machines on any interval you want and notify you any way you want (email, sound, etc.).

Hope you find it as usefull as i have...

enjoy.

Hi Anthony,

you should be able to use telnet in a script like every other command, if you know the structure of a script file: It is ASCII text file, this means at the end of a line there is a RETURN which is also registered when a shell is reading and interpreting the script. So you can use the lines

telnet host_that_you_want_or_IP
login_name
password

as alternative you can use the rsh-command without password, if you did the requested configuration. ( host- and system- aequivalency files are configured )

Allways stay on the bright side of life!

Hi

With telnet you can try something like this

#(sleep 3;echo ;sleep 3;echo ;sleep 5;echo;sleep 5;echo "uname -a"; echo "exit")|telnet
