Ifconfig NOT working

Joy Stick · 03-25-2017, 04:06 PM

Hi all

I connected as 'oracle' user.
Initially ifconfig command worked for 'oracle' user.
Now it is not working - Why so >

PHP Code:



$ ifconfig
-bash: ifconfig: command not found

PHP Code:



$ /sbin/ifconfig

RH does not put /sbin in a regular users path environment. Are you sure it did work before?

Hi,

RH does not put /sbin in a regular users path environment. Are you sure it did work before?

Yes. Usually i check ifconfig as 'oracle' user only. IT WORKED 2 days before.

In #1, are you saying that /sbin/ifconfig works NOW, as shown in 2nd Code block??
IF so, web-research $PATH
IF not, use `ls -l` to see if the file is there. Also, `ls -ld /sbin` to see the modify-date of /sbin.
Let us know. (there's other commands to find/stat a file) Also, see if `ip a` might have replaced it.

I do not run Oracle which might add it to the path. What is the oracle's users path?

I run CentOS but it should be the same. My default path for Centos 5.x:
/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/username/bin

The default users path for CentOS 6.x is below which does contain /sbin
/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/username/bin

You can use "ip" instead of "ifconfig". In fact many distros no longer install ifconfig by default with a minimum install.

IP cheat sheet - via redhat.

Otherwise $(sudo apt-get install net-tools) in debian to install ifconfig.

JJJCR · 03-26-2017, 09:06 PM

ifconfig has already been deprecated in some Linux distro, if I'm not wrong.

For RH try: ip addr show eth0

Check out this cheat sheet from RH website: https://access.redhat.com/sites/defa..._jcs_print.pdf

Never notice that the link above has been posted.

Try this link also: https://github.com/bertvv/cheat-shee...ter/src/EL7.md

If you are a subscriber of RH, get help from their support. Anyway, you're paying for it.

Good luck!
