Just telnet to port 21 on the machine, use USER <username> and PASS
<passwd> to login, then send your commands. Hope you're really
familiar with FTP commands (such as PORT, CWD, LIST, PASV, the ones
your client makes transparent), because otherwise it'll be a bit
difficult.

outside of network ? if they have a public IP the whole world is the
network ..
usual (and deadly) setup offered by some ISP:
internet,gateway----HUB------ client1
------ client2
------ clientx
needless to say that this is an security nightmare. Note that all clients
sit in the same networksegment and the gateway does not.
My ISP offers such solutions and when I set my nic to promiscous mode I see
a lot of stuff floating by that does not belong there ... :)
You can also have the following:
internet, isp-gate------router-------client1
-------client2
-------client3
where the router can also be a firewall or whatever. In that case the
clients have the router as gateway or (if bad configuration) the
isp-gateway.
In that case the router must allow the clients connections to the internet
and maybe this was your problem.

Not needless :) You are sure, all routes were set proper ?

no, this is the machines where packages are sent to next. In other words:
every route from inside to outside goes via gateway.

iit should but it need not. you can set routes per interface or per
gateway. If set per gateway the specified gateway needs not to be reachable
via one hop.

I think you have one of the above configurations but of course there are
some other mystical things that can take place here.
I would recommend reading the network-howto.

Necessary for what? Not for "working"! That file is only "necessary"
for forcing a menu choice automatically for a xdm-mediated login -
and even then only if it's mentioned that way in your systemwide
initrc. Lots of factors intervene.

This hardly requires study! That's like saying "I've been training so
hard that I haven't studied up on how to walk to the door of the
breakfast room". Edit /etc/passwd and give yourself an account. This
should absolutely be step zero in the use of any machine. How can you
possibly test any of your installations if you don't have any users
to test them?

No. Asking a hacker is not the least bit risky (execpt for the risk that
his fee might break your budget). Asking a _cracker_, on the other hand,
could involve taking a chance.

If the machine is there, so is the temptation (For crackers, that is.
Hackers do not engage in such stupidities).

Sure, you need some type of software that does xterm. All that I know are
commercial, Exceed is one that I have used before. There is VNC which is free,
but not exactly X. you run a vnc client on wintendoze which connects to a vnc
server on the linux box. The other neat thing about vnc is it works in the
opposite direction. I use a vnc client on my linux box at work to connect to a
vnc server on an NT box.

Not a dumb question. There is a product called exceed (which doesn't)
which provides this fuctionality. It's not the most fun to get
working, but it does work. If all you need is simple access, though,
SSH works great.

Even easier than that--on RedHat, simply type 'useradd -m <username>'.
The -m creates the user's home directory. Simplicity itself. But one
should definitely learn the /etc/passwd format--in some cases it can
save one's life.

Subject: nfs mount degrades performance
In doing some benchmarking on some redhat 7.1 boxes, I discovered that
if I mount a remote nfs file system using the mount command and then run
my little benchmark (which just increments a counter), the test takes
three times as long. This occurs even though there is nothing using the
nfs mounted file system, i have not even done a cd to it. The are no
obvious resources being used, it's not swapping, there are no other
processes using significant cpu. I have tried every combination of
options on the nfs mount. Now what is really weird is that if the same
nfs file system is mount through the automounter rather than using the
mount command, there is no degregation on the performance. Anyone got
any clues?

Hi,
I'm planning to create a raid-5 array of 3 18Gb scsi drives (not
important). As usual the devices are called sda,sbd and sdc. My question
is; what if the first disk,sda, (which contains the Master Boot record)
failes?! How am I supposed to get the MBR on the new disk I'll put in? It
would be pretty nasty if I couldn't boot my systeem anymore because of
this. Does anyone got a solutions to this? offcourse. I could run lilo
again, but what if the netpower suddenly fails? Maybe you don't count on
it, but it just might happen.
thanks in advanced,
Frank de Bot!

Sometimes Gnome is a little flakey. It was a lot worse in RH6.
I find it Ok now I have everything else stable. The other day gmc went
fritz on me though! It crashed leaving a rouge task that could not be
removed. The rough task occupied much of the CPU time as well, I had to
re-nice it so I could use the system. In the end a restart was recessary
:-( That was the first time EVER I had to re-boot Linux :-(
gmc also screwed my /tmp in the process - lucky this is a seperate
partition - yep it pays to have multi-partion filesystem!!!
I'm sure there is a way of removing rough tasks - anyone?

I had a few problems which I resolved ... one was that I didn't have

that I didn't have the usbdevfs filesystem enabled in the kernel.
After that I was able to use s10sh like a charm with my camera! WOW

Exactly. I have all of those files in those locations. Today i got it to
work for me at work by making symbolic links in the /lib directory.
Still cant get it to do it at home. Still get a dependency problem when
i try to run the rpm. Any other ideas?
