The spring runs mostly on bsdi unix boxes. Although we're phasing in some
Microsoft NT servers.

Ted, we're continuing our discussion we started in linux here
Look what happened when I tried your commands. And look at how much space
there is now and compar it to the space that there was on here a couple of
days ago which I documented in the linux topic. I probably outht to move
that linux top cstuff here in the next post.

Terry, which directory is short of space on barton? /home is
only 12% used, still have about 600MB left :-)

/var and /usr are both real full.
I need to add to /var because that's where a bunch of mail
keeps overflowing and filling up the hard drive. I could use
a lot more room there.
I'm thinking about plugging in a 3 gb Quantum and setting it
up as the second drive on www. Any tips on upgrading that
system (step by step procedure). I guess the first would be
to plug it in and run BSDI's disk formatting program. Then
link it to /var as a filesystem.

For short run you can link /var to /home since /home has
600MB of space. To do this, just run run on shell:
mkdir /home/var ; ln -s /home/var /var
make sure /var is not there in the first place.

Do I need to reboot for it to take effect now?

Re: /var on barton
Terry, I just did an 'du' on /var at barton and found below
directories has eaten the most space:
17818 ./www
60920 ./account
22142 ./log
8218 ./webdocs
You don't have to reboot barton. What I found you have not link
/var to /home/var, to to this, see below step-by-step:
1. rm -f /home/var
2. mv /var /home/
3. ln -s /home/var /var
This will make a link from /var to /home/var

The problem I'm having now, Ted, is that when I open elm to read my mail
it shows that I have no mail because it's still looking for /var/mail and
my mail is now in /home/mail or /home/mail/var or something. How do we
fix this?

Password:
barton# cd /
barton# mv var vartemp
mv: var: Device busy
I tried this because you said to:
su
cd /
mv var vartemp
ln -s /home/var /var
And after this, doing an ls -l / to see
/var -> /home/var
Why Device busy???
Should I try again?

As it stands now, I go to elm and see no mail because it's over in the new
directory.

Now back to BSDI unix, how can one disable ICMP packets?
What I mean is disable someone from the Internet ping your host....

We had a ping atttack once and we tracked down the ping bomber and had his
account terminsated. It was senseless . Why pick on little Spring?
Some firewalls and deal with ping attacks. And you might search omse the
the Interneet security websites. There may be something about his in our
security topic.
These are also calle Denial of Service attacks.

Ping attacks happen everywhere, they don't spare small host. I
have looked into my router's manual and found something like
"Disable ICMP redirects" and may be it gave me some clue...

Now, Ted, will you please tell us exactly how to do this step by step
so we can learn from this?
Good job, Ted!
Now, do you know how to restart our realaudio server which has stopped.
I know, but I left my notes at home today.
We run realaudio for our http://www.childrenstory.com website.

Re: df and ln
It's a simple task, I went to /var (at barton), became root,
then move all files and directories to /home/var by using
"mv /var /home", then make symbolic links by using the ln
command to each directory in /home/var, for example:
ln /home/var/spool /var/spool will link /var/spool to
/home/var/spool. The actual way is to make /var point
to /home/var but due to some files used by the system
it can't be done without a reboot.
more info at "man ln"
For readAudio, let me take a look tomorrow (it's 12am now in
Singapore).

The Realaudio thing is a hot issue. Email ces@well.com and
ask him how to restart it.

Dave Thaler set up a "most recent postings" are today and I'm testing it.
Take a look at the "main menu" and you should see this post, or you will if
it's still recent.
