External login

[Harsh Pareek]

Hi,

I think now is a prudent time to discuss how to login to iitb to access internal sites from outside.

You can potentially register from outside IIT using this, but please don't. :P
As per institute rules, you should be present within the institute when you register.

The procedure varies by department, and you will need to use your department ID/password to actually login.

For CSE, 

ssh sec...@login.iitb.ac.in -p 5022

with password extvoxacc 

Then choose 'mars' as your server. You will have to put in your CSE department username and password to login to mars.

From there, you can ssh to any nsl/osl comp and use w3m or elinks to browse the internal sites.

For EE,

SSH to login.iitb.ac.in on port 7022 with username as gateway and password as toiitb. You will be prompted for your sharada username, and it will open an SSH connection to sharada

If you know the details for other departments, post them here.

So, I guess they use the port numbers( I see a pattern with the roll numbers CSE->5 and EE->7) and maybe account name to decide which server to forward the connection. I'm not sure how this works internally, but perhaps they have written a custom program for this or perhaps there is some standard package to set this up.

Note: I had some problems with elinks (It would not show some buttons). So I had to use w3m and the hindi version of the asc page.

So we must register from insti. We can atleast view courses etc. through this. I guess that would be within the rules right :-)

I thought I copy pasted the details for each dept ports and all few months ago

Ah, searched and found it. [Didn't find it earlier for some reason, maybe because the title and keywords were different]

This data is from http://web.iitb.ac.in/web/outside-access.php , which is appropriately, only accessible from inside IIT.

Accessing IIT servers from Outside IIT  Facility is provided to connect to IIT servers (one per department) from outside IIT using telnet and ssh. This facility is implemented by server login.iitb.ac.in.  To access any dept. server, one has to use the port allocated for that dept. For each server there are two ports allocated; one for telnet and one for ssh.  e.g. To access cse dept server using telnet the following command is used  telnet login.iitb.ac.in 5023  e.g. To access cse dept server using ssh the following command is used  ssh -p 5022 login.iitb.ac.in  NOTE: Though each server can be accessed using telnet and ssh, it is recommended that you use ssh, so that your passwords are not sent in cleartext on the network. The windows clients for secure shell and secure copy can be downloaded from here. Putty. Pscp.

Does this work? Did anybody test this?

[Harsh Pareek]

Yes, it does work. I have used it to login to my CSE account for registration (using w3m).

There is some issue with the text based browsers. They do not render all the text fields/buttons, but everything worked out (for me).

[Prashant Sohani]

why do you need text-based browsers? X forwarding works very well (atleast on ee)

The physics one doesnt have a login. We have been trying to convice numerous GSecs, HoDs for those, but to no avail.

So....what's the point of the port? Without a main login (it's not hard to get Physics LDAP), we can't even get to the secondary login screen. What's the point of having the login.iitb port open? :S

Welcome to the amazingly WTF world of digital beurocracy!

Here you do things because you are told to do so, eapecially without putting an "iota" of your common sense. And believe me, its much better that way.

The rest of the departments do use this port.
