On Linux there is a nice tool for testing connections, bandwidth, opening temp. connections etc: nc
What is equivalent on Juniper firewalls?

Please clarify if you're talking about NetScreen or SRX line of firewalls, they use two VERY different operating systems.– SpacemanSpiffApr 12, 2012 at 18:33

@SpacemanSpiff sorry, I was talking about NetScreen.– AlexApr 13, 2012 at 1:34

get route , get tcp , it depends on what you want to accomplish .
Please have a look here http://fir3net.com/Netscreen/juniper-commands.html and here http://www.juniper.net/techpubs/en_US/junos/information-products/topic-collections/swcmdref-basics-services/swcmdref-basics-services.pdf

Can one of these commands listen on a "temporary" port (while the command is running)? Can one of these cmd test if a TCP port is open on a remote machine?– AlexApr 13, 2012 at 1:35

This does not allow you to measure bandwidth and only allows one way connection. I am looking for a more powerful command– AlexApr 25, 2012 at 1:36

Seems Juniper does not provide any tools to measure bandwidth end to end. One can only do it via the connecting clients on both sides (with the proper routing/vpn in between).– AlexJul 18, 2012 at 8:28
I think the closest thing might be telnet

(I know this is a ScreenOS question but...)
In current JunOS nc isn't there, but you can just use telnet to arbitary ports.
If you need incoming you may have some luck using inetd.
