Lab 1 FAQ's

1. How do I get included in the mailing list and get an account in RCS?

A: Send a mail to Adnan El-Nasan elnasan@rpi.edu requesting to be included in the mailing list for Internet Protocols (IP-L) and if you don't already have one, be given an account in RCS.

2. OK. I am in the mailing list. What else?

A: You need to have an RCS account. See Q 1.
Once you have an RCS account,

Increase your disk quota from the default 5 MB to 10 MB. Here's How you go about it:

quota_request -quota 10

you will also be given a account in the networks lab. A mail will be sent regarding this

3. I think I am not on the mailing list. How do I verify?

Check http://www.egroups.com/group/ip-s2000/ If you did not receive the msgs posted in the newsgroup then you are not on this list, send a mail to Adnan El-Nasan elnasan@rpi.edu

4. How to logon to the testbed network ?

- You will need to logon to the testbed network in order to use the tcpdump program. You will use that in HW2.
- All students in the above list have accounts on the testbed network, according to the list in item number 3 above.

- Your testbed account is the SAME as your RCS account. Your password is initially set to be the same as
your account.

- !!! Please change your password immediately after you logon using the passwd command. !!!!

    - You will have to use SSH to logon to the testbed network. If you are an on-campus student, then you already
        have ssh agent on most machines on campus.
        * To obtain ssh, please see item 5 below.
        * To learn how to use ssh, see item 6 below.

   - To logon to the testbed machine please use this IP address :     128.113.51.10
        Later on, this machine will be given a name and we will announce it to you. In the mean time, you have to use
        this IP address.

- For example, you could do the following from a unix station that has ssh agent :
ssh -l testid 128.113.51.10

Replace testid with your account id and try to logon.

5. How to use ssh ?

Type the following without the < > :

ssh -l <your-id-on-remotemachine> <remote-machine>

For example:

    ssh -l testid rcs-ibm2.rpi.edu
          ---
              |---------> This is an 'L' in small letters, not a '1' .

6. How do I get SSH ?

General Info:
http://www.ssh.fi/ (free stuff)
http://www.datafellows.com/ (non free stuff)

Downloads:
Unix: (ssh1)
ftp://ftp.cs.hut.fi/pub/ssh/ssh-1.2.26.tar.gz
Unix: (ssh2)
ftp://ftp.cs.hut.fi/pub/ssh/ssh-2.0.11.tar.gz (also get the
patch-ssh-2.0.11)

Win:   (ssh1/2) (Just get the trial version)
     http://www.datafellows.com/gallery/
     choose "F-Secure SSH Tunnerl&Terminal for Windows" from the first popup

MacOS: (ssh1/2) (Just get the trial version)
http://www.datafellows.com/gallery/
choose "F-Secure SSH Tunnerl&Terminal for Macintosh" from the first popup

the unix ssh client/server also does X11 forwarding (over the active
connection) so there is no reason to export a DISPLAY assuming both sides
are setup to allow it.

7. List of AIX machines (These are NOT part of the testbed network. These are needed for LAB1):

    rcs-ibm1.rpi.edu
    rcs-ibm2.rpi.edu
    vcmr-19.rcs.rpi.edu
