hi there,
i currently use Fedora
my question is that
when i connect another Fed using ssh it shows connected
but when i execute any command like:
ssh user@ip_addr ls
it shows ls of my own pc
plz show me a way to execute commands on remote pc via ssh
or any other possible way /without installing packages/

Are you sure? Because it should not be working like that. Can you show us an example?

falcon24,

I have to admit that I am not using Fedora, but I am using Red Hat Enterprise Linux. Your command is right on the money. I ran several tests, just to make sure, and the results are:

ssh user@ip_addr ls: works just like it is expected too.

ssh user@ip_addr command_requiring_root_privilege: after successful login, I receive "PERMISSION DENIED"

ssh user@bad_ip_addr ls: ssh: connect to host x.x.x.x port 22: No route to host

After trying multiple different commands, I was never able to get the command to fail and give me a ls of the local machine. Is it possible that the directory of the user that you are remoting in as has the same content as you do on the local machine?

Example: Your home directory is on an NFS filesystem on both machines (/nfs_dir/user). if you were in your home directory, and used the command given above (ssh user@ip_addr ls), the "ls" on the remote system would be of the same directory you are in (/nfs_dir/user)

You might try and post the output if you are still having issues. When you do this, also upload from your local machine.

Actually
the PC's arent connected
the only thing is that they have same internet connection
i m sure commands are executing on my own pc
and commands such as shutdown reboot dont work via ssh
my doubt is
even after ssh shows connected why it does not execute commands on remote machine
do i need to start any spefic service (apart from sshd) on remote

PSlz post if you know to exec commands on remote pc via ftp
and also few ftp sites which i can use to test ftp commands


#Linuxrocx

it does

You're either doing it wrong or you don't understand what you're seeing. To resolve EITHER of these issues you NEED to provide details and examples like you've been requested to do twice already.

FTP stands for "file transfer protocol". It's for transferring files, you can't run commands on the remote machine.

You don't need any additional services. sshd starts whatever program you tell it to, and if you don't specify the program, it will start the shell.

Perhaps both PCs have the same IP address?
Or: When you run ssh user@ipaddr (without a command), are you sure you are connected to the remote system, and not the local system?

If this doesn't help, you can also raise the level of verbosity on the client, with -v, -vv and so on. There are also verbosity options for the server, sshd.
