hi

I want to use the arp command (read about it in some network book) but when i type arp it isn't recognized
Does anybody knows where to find it?

I checked the net and it's in the net-tool package

I have the latest version installed

# rpm -q net-tools
net-tools-1.60-52

# ifconfig
bash: ifconfig: command not found

# arp
bash: arp: command not found


But even ifconfig does not work ...
Please help?

Some commands need root user to run and even so, you should put the dash ( - ) after su to get the path. Otherwise, you can find out where the program is located, then use the full path to a command.
For example: su -
and to find out where the program is, use the command:
whereis arp or whereis ifconfig
The command which arp or which ifconfig will work also.
Then, use the results..... /sbin/arp or /sbin/ifconfig

thanks a lot!

But i worked on a RH 9.0 machine and there ldconfig worked just by typing it in the terminal
any idea why this does not work on FC4?

is there a way i can put the path /sbin (where arp and ldconfig are) in a configuration file so when i type arp, ... the terminal will loook in that path?
I'm just a beginner but maybe this is possible?
If you tell me in what file this belongs it would be very handy !

You can put it in the users hidden file called .bash_profile . The easiest way for a beginner would be to open the file manager called Konqueror and select View / Show Hidden Files.
Now you can open ./bash_profile and add a path to /sbin in there like this...
PATH=$PATH:/sbin

You may need to logout and back in for those changes to happen. Also, some programs are not meant to be run by users and you get permission denied messages.
For example:

$ dhclient

thanks a lot

Glad to help!
