Using Telnet

The Linux operating system used by the maximiser system can be directly accessed by using the "Telnet"
protocol. Telnet provides simple access to the command line interface that you will need to use when
troubleshooting the system. To telnet on to a call server please refer to the Root Access to a Call Server
section from page 272. You will enter the directory /root from where you can enter the following
commands.
Linux Commands
The following commands can be used via Telnet:
cd - change directory
cd / - go to root
cd /directory name - change to the named directory eg cd /ftp
cd .. - back one level
ls - view files and directories stored in this directory
ls -l - view files and directories stored in this directory plus details eg size, date
ls -l B* - view files beginning with B
pwd - view current location (Print Working Directory)
exit - exit Telnet
cp a b - copy a to b
mv a b - move a to b
(This command can also be used to rename a file eg mv Admin_1265.log trace1.log)
rm - remove eg rm Admin_1265.log /ftp
Where a long file name must be entered the Tab key on your keyboard can be used to auto complete a
long entry. Enter the first unique letters of the file name and then press Tab, eg mv A then Tab may find
mv Admin_. If only part of the file name is displayed you can continue to add unique parts of the file
name and then press Tab until the complete file name is displayed.
