993 :-) :-)
Specifically what's going on here is that fedora netcat is not the old
netcat you know.
A little while back (I don't remember which release) it was replaced by
nmap netcat (ncat):
[root@server ~]# rpm -qf /usr/bin/nc
This does not have the old -z option as you mention... tcping is the best
of the options others have presented (no idea what that person was going on
about netstat for...)
The other alternative to tcping is nmap ...
nmap -Pn -p993 imap.gmail.com
Thanks a lot! I had a suspicion the issue was something like this.
This is extremely inconvenient though, since now I have to change quite
a few scripts, more importantly now I also have to figure out the
machine my script is running on (e.g. laptop or institutes servers).
I guess switching to nmap might resolve the second issue.
Open source is the future. It sets us free.
