How to get IP of computer assigned by DHCP?
I have a computer at work with no control over the network settings. We have to pay for a static IP so that won't happen. I'm running an SSH server so I can connect back and analyze data when I'm sitting in boring classes.

I want to know how to get the IP of this machine when I'm on the same network.

Previously what I would do is either grab it before I leave the office, or I set up a script in mail that would email me the IP address if I sent a very specific e-mail to myself.

I'm not very good with networking, and to make matters worse, I'm on an iPad with no true access to a console.

No, this is not illegal, I'm friends with the IT guy on the floor, and he says it's perfectly fine. However, I don't think running a network scan would go unnoticed.

So, what is the best way to do this? My e-mail script only works if the computer isn't asleep, and it especially doesn't work if I forget what to e-mail myself.

Any help?

I could potentially connect to my home server, VPN into the network, then run a bash script that looks for my server but... I don't think that's a great idea.

auscope

AUSCOPE(1)						      General Commands Manual							AUSCOPE(1)

NAME

       auscope - Network Audio System Protocol Filter

SYNOPSIS

       auscope [ option ] ...

DESCRIPTION

       auscope	is  an	audio  protocol  filter  that can be used to view the network packets being sent between an audio application and an audio
       server.

       auscope is written in Perl, so you must have Perl installed on your machine in order to run  auscope.   If  your  Perl  executable  is  not
       installed  as  /usr/local/bin/perl,  you should modify the first line of the auscope script to reflect the Perl executable's location.  Or,
       you can invoke auscope as

       perl auscope [ option ] ...

       assuming the Perl executable is in your path.

       To operate, auscope must know the port on which it should listen for audio clients, the name of the desktop  machine  on  which	the  audio
       server  is running and the port to use to connect to the audio server.  Both the output port (server) and input port (client) are automati-
       cally biased by 8000.  The output port defaults to 0 and the input port defaults to 1.

ARGUMENTS

       -i<input-port>
	       Specify the port that auscope will use to take requests from clients.

       -o<output-port>
	       Determines the port that auscope will use to connect to the audio server.

       -h<audio server name>
	       Determines the desktop machine name that auscope will use to find the audio server.

       -v<print-level>
	       Determines the level of printing which auscope will provide.  The print-level can be 0 or 1.  The larger  numbers  provide  greater
	       output detail.

EXAMPLES

       In  the	following  example,  mcxterm is the name of the desktop machine running the audio server, which is connected to the TCP/IP network
       host tcphost.  auscope uses the desktop machine with the -h command line option, will listen for client requests on port 8001  and  connect
       to the audio server on port 8000.

       Ports  (file  descriptors)  on the network host are used to read and write the audio protocol.  The audio client auplay will connect to the
       audio server via the TCP/IP network host tcphost and port 8001:

	      auscope -i1 -o0 -hmcxterm

	      auplay -audio tcp/tcphost:8001 dial.snd

       In the following example, the auscope verbosity is increased to 1, and the audio client autool will connect to the  audio  server  via  the
       network host tcphost, while displaying its graphical interface on another server labmcx:

	      auscope -i1 -o0 -hmcxterm -v1

	      autool -audio tcp/tcphost:8001 -display labmcx:0.0
