Hi, I just installed SuSE 9.3 Pro. on Win XP to my Dell Inspiron 1200 using VmWare. After I installed NS2, which is a network simulation program, I typed ' ./install ' at ' /root/ns2/ns-allinone-2.28 ' and the installation was fine. Then I had to edit ' /root/etc/profile' to set up the path for the NS2 program. Below is the edited part.

----------------------------------
#
# Make path more comfortable
#

if test -z "$PROFILEREAD" ; then
PATH=/user/local/bin:/user/X11R6/bin:/bin:/root/ns2/ns-allinone-2.28/bin:/root/ns2/ns-allinone-2.28/bin
-----------------------------------

However, when I type ' ns ' after the editing, I got this error message :

' bash: ns: command not found '

But, the command got no problem because....If I copy ' ns ', the exacutive file, from :/root/ns2/ns-allinone-2.28/bin to ' /root/bin ' and type ' ns' It works~~! If I erase the ' ns ' from /root/bin , it is not working anymore.


Q1. I think there was some mistake during editing the profile but I don;t know what it is. please please help me.

After changes to profile you must close and restart your shell.

ive never seen "/user/"...its always "/usr/" ...and most likely you should be editig /etc/profile and not /root/etc/profile..

many thanks to ganja_guru and jojob~


1. I restareted my shell after I change the profile, but still nothing happens.

2. Yes, ganja_guru..u're right its /etc/profile not /root/etc/profile..
but still nothing happens after I change the /etc/profile

Normally, using SuSE, you edit /etc/profile.local instead of /etc/profile.

Also, the script is run when logging in. So either you need to start a shell like /bin/bash -l or log-out and log-in.

I do hope that you are not running as root, this is a really bad idea.

Is ns2 installed in /root. If it is, it will only be accessible to the root user, not regular users. Try installing it to /usr/local.

Once you have installed ns2 to /usr/local, try making a symbolic link to the ns2 executable in /usr/bin.
Assuming that /usr/local/ns2/ns-allinone-2.28/bin/ns is the path to ns.

By making symbolic links, you remove the need to edit your $PATH.

You might need to make a link in a similar fashion to nam (I think)

I hope this helps
