I'm trying to send fwknop SPA from linux command. The syntax is

echo 1234 | fwknop --Home-dir /tmp -f 5 -A tcp/80 -a $1 -D google.com > /devel/null 2>1 &

However I'm getting an error like "-bash: echo: write error: Broken pipe" If I try the same command from another centos it works without any issue so I don't know how to fix it. The both servers are running the same version of centos (5.5) with the lasted updates. Thanks a lot for any help !

/devel/null

shouldn't this be /dev/null?

also, check the installed packages and try running fwknop without redirection (no echo or /dev/null). The command may be failing
