Utility like nc

Hi Gurus,

Do you know any utility like nc in BSD. Actually I want to take some output from one server's port & would like to store in variable.

When I am giving telnet abc 28000 | grep ok then output is coming .
ok
Connection closed by foreign host.

I want to get only ok value. I don't want "Connection closed by foreign host.". Is there any way or can I get any utility like nc ?

c=`telnet abc 28000 | grep ok`
echo $c | awk '{print $1}' ??

Hi

Go to www.software.hp.com

choose public domain

look at

Netcat 1.10
=========== /\_/ / 0 0 Netcat is a simple Unix utility which reads and writes data ====v====

scripts. At the same time, it is a feature-rich network / / \ \ |

as another one of those cryptic but standard Unix tools. /

In the simplest usage, "nc host port" creates a TCP connection to the given
port on the given target host. Your standard input is then sent to the host,
and anything that comes back across the connection is sent to your standard
output. This continues indefinitely, until the network side of the connection
shuts down. Note that this behavior is different from most other applications
which shut everything down and exit after an end-of-file on the standard input.
