i am new in linux 9 and my problem is how can mount usb pen drive in linux 9
No offence naveen_dlink but have you seen anything about pen drives in this thread?
Why didn't you search the forum and google. There are lots of threads/ information about
linux and pen drives. Alternatively, if you can't find the answer to your problem, start your own thread.
btw, there are no such thing as 'linux 9'. Linux (the kernel of the os) is currently at 2.6.24. There are different flavours of linux which are called distros (distributions). Judging by the number '9' you may mean RedHat.
