you can access remote pc via different method like telnet, vncviewer(for graphical access), ssh but make sure that these services installed on your system any wey the cheap method is using ssh.
Using SSH, you are provided a shell nearly identical to one available locally. this provide all command line functionality
To ssh in remote computer u need
1. static ip address of that machine which u want to access remotly or locally
2. rights to access that machine
The First time when you login to the remotehost from a localhost, it will display the host key not found message and you can give “yes” to continue. The host key of the remote host will be added under .ssh/hostkeys directory of your home directory.
localhost$ ssh -l anil98433 remotehost.example.com
Host key not found from database.
Key fingerprint:
xabie-dezbc-manud-bartd-satsy-limit-nexiu-jambl-title-jarde-tuxum
You can get a public key’s fingerprint by running
% ssh-keygen -F publickey.pub
on the keyfile.
Are you sure you want to continue connecting (yes/no)? yes
Host key saved to /home/anil98433/.ssh/hostkeys/key_22_remotehost.example.com.pub
host key for remotehost.example.com, accepted by anil98433 Mon May xx xxxx xx:xx:xx -xxxx
anil98433@remotehost.example.com password:
remotehost.example.com$
now you can access that computer
The Second time when you login to the remote host from the localhost, it will prompt only for the password as the remote host key is already added to the known hosts list of the ssh client. and you will ask about only password if it is correct as you have enterd previously in first step then you get access the shell
localhost$ ssh -l anil98433 remotehost.example.com
anil98433@remotehost.example.com password:
remotehost.example.com$
To copy the files from remote computer ssh use scp protocol
Copy file from the remotehost to the localhost:
localhost$scp
anil98433@remotehost.example.com:/ho...tehostfile.txt remotehostfile.txt
Copy file from the localhost to the remotehost:
localhost$scp localhostfile.txt
anil98433@remotehost.example.com:/home/anil98433/localhostfile
you can also use Telnet service to access remote computer but before it you have to install telnetserver and rpm package from linux cd which you can install using
rpm -ivh telnet*
then
telnet <ip address of the computer u want to login>
enter user id:
enter passwd:
you can enter in to that
for vncviewer you must have to configure vncserver first which is long process. i hope these above two enough for you
