In my Windows system, I was able to create a tunnel by running the command below using Putty:
putty.exe -D 12345 -P 8888 localhost
I'm not used to Mac yet and I would like to try it out on Mac. Does anyone know the command to achieve same tunneling in Mac OS X or do I have to use a client?

putty's command-line options are (mostly, but not entirely) a clone of those that the openssh client uses, so the equivalent of your command line above would just be ssh -D 12345 -p 8888 localhost.
Read man ssh for the full details of the options.
Well. I don't know why you'd forward ports to localhost, but I'm sure that was just a demo ;)

Thx James. I will try your answer out. :)) . As to why I would ports to localhost, it is needed for bypassing stubborn firewalls. – None – 2012-02-04T07:57:14.270
UPDATE: I just tried it but it failed, it appears an attempt was made to connect Host 8888 on port 22 which is wrong. ........................ ssh -D 12345 -P 8888 localhost ssh: connect to host 8888 port 22: Network is unreachable – None – 2012-02-04T08:04:12.517
Hah. I missed that. it'll be -p 8888 rather than -P 8888 :) – James Polley – 2012-02-04T08:57:50.377

MacOSX provide by default a command-line ssh client, just execute it from a terminal with:
$ ssh user@hostname
To check that options are the same that you are accustomed with PuTTY, read the ssh man reference with:
$ man ssh

Mac's ssh syntax (and for most other *nix commands) is not the same as in a Linux box. I think you could try ssh -D 12345 -p 8888 localhost, but I don't remember quite well. The best way is man ssh.
I usually make a config file (.ssh/config) with parameters so that you can simply type ssh bypassfw if you want to run that command.
Host bypassfw
HostName localhost
Port 8888

Thx for the suggestion. Just tried it but it failed. – None – 2012-02-04T08:44:31.583
I forgot "localhost" in the command. I also added a .ssh/config file, the method which I used when I was on Mac. However, did you try man ssh? – jcisio – 2012-02-04T08:46:13.420
Did'nt work out :(( – None – 2012-02-04T09:43:59.813

Not sure if this is still relevant or not. But I used this command.
ssh -L 8080:192.168.0.12:9991 remote_user@192.168.0.12
Basically,
ssh -L local_port:remote_ip:remote_port remote_user@remote_ip

What are you trying to accomplish? I don't know putty command line options, so I'm not sure what traffic you're actually trying to forward, and in which direction. – cjc – 2012-02-04T14:09:26.300
