Operating Systems Linux How to hide login messages ? Post 302497134 by Corona688 on Wednesday 16th of February 2011 12:31:59 PM

I don't see a way in my version. They're not login messages -- they're generated by the telnet binary itself, and printed to stdout, not stderr.

Perhaps telnet isn't the right tool for the job? If you're trying to script anything, netcat(nc) will save you lots of headaches over telnet because it never pretends to be a terminal... It just sends everything it has to send, receives until the other end closes, then quits. For instance:

Code:
$ echo "GET /" | nc yahoo.com 80
<!DOCTYPE html>
<html lang="en-US" class="y-fp-bg y-fp-pg-grad  bkt701">

fence_rsb(8)						      System Manager's Manual						      fence_rsb(8)

NAME

       fence_rsb - I/O Fencing agent for Fujitsu-Siemens RSB

SYNOPSIS

       fence_rsb [OPTION]...

DESCRIPTION

       fence_rsb is an I/O Fencing agent which can be used with the Fujitsu-Siemens RSB management interface.  It logs into an RSB device via tel-
       net and reboots the associated machine. Lengthy telnet connections to the RSB device should be avoided  while  a  GFS  cluster  is  running
       because the connection will block any necessary fencing actions.

       fence_rsb  accepts  options  on	the  command  line  as well as from stdin.  Fenced sends parameters through stdin when it execs the agent.
       fence_rsb can be run by itself with command line options.  This is useful for testing.

       Vendor URL: http://www.fujitsu.com

OPTIONS

       -a IPaddress
	      IP address or hostname of the RSB device.

       -h     Print out a help message describing available options, then exit.

       -l login
	      Login name.

       -n telnet_port
	      The port number on which the telnet service listens.

       -o action
	      The action required.  This can be reboot (default), off, on, or status.

       -p password
	      Password for login.

       -S path
	      Full path to an executable to generate the password for login.

       -v     Verbose.	Print informational messages to standard out.

       -V     Print out a version message, then exit.

STDIN PARAMETERS

       agent = < param >
	      This option is used by fence_node(8) and is ignored by fence_rsb.

       ipaddr = < hostname | ip >
	      IP address or hostname of the device.

       telnet_port = < port number >
	      The port number on which the telnet service listens.

       login = < param >
	      Login name.

	      The action required.  This can be reboot (default), off, on, or status.

	      Password for login.

       passwd_script = < param >
	      Full path to an executable to generate the password for login.
