I would like to remove rsh, rcp, rlogin from my production server.

How would i go about it?
Should i remove them from their original location using rm?
Will that impact on any other functionality?

which distribution are you using?
it is not advisable to remove them using rm.
It's always better to use the package manager, or you will have commands to add or remove a software in your distribution.

If its rpm based distro

List the rpm

Remove the rpm


If its debian based distro
List package

Remove package

--purge:removes package and configuration files

Mine is rpm based distribution.

But i could not able to find rpm for rcp and rlogin.

Distribution Details.

rcp and rlogin commands work in your system?

Did you use source code for installing rcp or rlogin?

I'd suggest you to change the permission for those commands or rename them instead of removing them. That way you can restore and get them working again whenever you want.
Use which command to know their location and then change their permission or rename them.

Change the file permisisons:

chmod 000 /usr/bin/rcp

chmod 000 /usr/bin/wget

chmod 000 /usr/bin/lynx

chmod 000 /usr/bin/links

chmod 000 /usr/bin/scp

why to re-use un-secured service when we have ssh?better remove rsh!

Hi
you nearly got it.
As far as I know rcp and rlogin is included in rsh-0.17-38.el5.
Do a "rpm -ql rsh-0.17-38.el5" to check. That should list the files belonging to
"rsh-0.17-38.el5".
You should be able to uninstall that RPM Package and get rid of what you want.

Thank you very much this is exact what i want.
# rpm -ql rsh-0.17-38.el5
/usr/bin/rcp
/usr/bin/rexec
/usr/bin/rlogin
/usr/bin/rsh
/usr/share/man/man1/rcp.1.gz
/usr/share/man/man1/rexec.1.gz
/usr/share/man/man1/rlogin.1.gz
/usr/share/man/man1/rsh.1.gz

From above methods i have noted down some methods of removing the command but i m yet confused which method should i follow.

As i m using it for my blog i have written it considering my blog in mind please help me evaluating the best one considering it wont affect other functionality.

It is highly recommended to remove following command on production server .
There are several ways of not using the command choose one that is suitable for your need.

Method 1:

Just try to find the rpm for the above command.
This can be done using.

As you can see only first command return any output.

We need to further see what command rsh-0.17-38.el5 contains.

This can be done using


From the output you can assume that by uninstalling the rpm you can achieve the removal of those command from production server.


Method 2:

Change the file permisisons:

(First check the location of command using which command name.Below examples are given considering the commands are located under /usr/bin/rcp This could be different for different Linux Distributions.)
Method 3:

just remove execute bit of the command using.


(First check the location of command using which command name.Below examples are given considering the commands are located under /usr/bin/rcp This could be different for different Linux Distributions.)


Method 4:

Remove the command itself using.

If there is a command or file on your rpm based system, you can find the package which installed it with the comand:
rpm -qf /path/to/command

For example:
rpm -qf /usr/bin/ssh
openssh-5.4p1-8.2.x86_64

This doesn't remove the package. This locates the package that installed the file.
You can not uninstall the package using rpm (or yum or zypper) command or using your package manager.

For files you built from source, running "sudo make uninstall" from inside the program's source directory will uninstall the files.

Yes it was wrongly typed .Please suggest the best way of removing the commands.

I would go with removing the executable bit


Kind regards

will this stop listening on port for rcp and rlogin?
