Ha, I couldn't've asked for a better setup! Here is my posting
assignment from digs (hi digs!):
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
For this project you will need:
1.a null modem cable
2.kermit or another like netterm for windoze /a comm program/
3.a linux boxen
4.a dos or wintendo boxen
5.slirp -you dont need this but its sure slick../a ppp-slip
emulator/
let's go!
unless you're handy with a soldering iron i suggest going
the easy route ;)
Go to Radioshack and get the following:
null modem adapter catalog# 26-264A
db 9pin serial cable catalog#heck even WalMart should
#have these.
If you're hard headed like I was /am ?/ you can make
your own.. note: charts are provided below.
grab a copy of kermit for ms-dos link below:
http://www.columbia.edu/kermit/mskermit.html
[BIG FAT NOTE]:unless you read up on the use of kermit mark
my words: your efforts will be in vain!
/I ordered the book along with the software it is really
good reading and I was up and running in 10min -+/
search your distro for a program called slirp or
search the net for it..this little puppy let's you login
to a shell account from a terminal then crank
up netscape or explorer etc.. from you wintindo box it's
very neat!
ok..
1.hook up you null modem cable: ms-dos/wintendo <--> linux
boxen
2.from linux as root edit the file etc/inittab
mine looks like this:
# Serial lines
s1:12345:respawn:/sbin/agetty -L 19200 ttyS0 vt100
s3:12345:respawn:/sbin/agetty -L 19200 ttyS2 vt100
s4:12345:respawn:/sbin/agetty -L 19200 ttyS3 vt100
after you make the changes save the file then as root type:
init q /this will refresh the system/
[ANOTHER BIG FAT NOTE]:you must have some type of getty.
I use agetty because it was simple to setup.
man agetty(1) for more details.
Make sure that your agetty is not trying to respawn on
a com port that a mouse is using!
What this does is tell agetty to listen on the lines
noted for a login:
ttyS0 = com1 in dos
ttyS1 = com2 in dos etc..
[YET ANOTHER BIG FAT NOTE]:agetty and kermit /must/ be set
to use the same speed or it won't work.
Note the string "19200".
Alright back to the wintendo side of the things:
from a dos box, cd to your kermit directory, then issue
the command: kermit
Next type: set lineX
/where X is the com port you chose to attach your
nullmodem to; ie. set line 1, then type set speed 19200
/where 19200 is the speed you choose in etc/inittab/
If you setup --everything properly-- you should see
a login prompt. If not tap the enter key on the wintindo
boxen a couple of times.
Now this alone will let you login and out of your linux
boxen, read news, email, etc..
But if you want to cruise the net using windows
via your linux boxen you will need slirp. I won't go
into the setup of slirp but you can figure that out for
yourself.
[THE LAST BIG FAT NOTE]:before you bust off and
try all this, grab a can of soda and read these links
and bookmark them they got me up and running.
goodluck..

Apparently glibc-2.0 and glibc-2.1 each have their own dynamic linker,
and they don't mix with the other's shared library.

you could reserve some of the swap area for root emergency. perhaps
there could be a superroot mode where your superprocesses run in core,
are unswappable and all other processes get stuffed into the swap
area. the superroot would simply push stuff into reserved swap since
it would always be there until needed. since disk is getting cheaper
every day (people `waste' disk in redundant RAID configurations), this
might not be too great a price to pay on a server needing 100% uptime.

Hi!
Could you tell me, when you read the toc with cdrdao, does it only
write the toc file, or also analyze each track? If the latter, why is
it doing so? It takes an awful lot of time (considering that I also
need to rip the cdda data off the CD)...
Thanks!

Subject: need help with RPM 3.0 install

I installed the new version of RPM in redhat 5.2 with:
rpm -Uvh rpm 3_0-6_0_i386.rpm
the next time I tied to use RPM It could not not open the package.rpm and
said to use --rebuilddb
Apparently I need to rebuild a database somewhere and possibly point to the
new rpm executable. Can someone describe how to use this so I can set this
up properly.
TIA

It *tries* to analyze each track, and yes it tacks a very long time...I
would GUESS at least the amount of time required to play the song.
cdrdao never finishes that part though, exits with a whole shit load of
errors, yet writes a viable toc file.....go figure....
My advice, when it sits there like a dumn shit, eject the CD and it will
force a toc file out of it :P....and yes, the toc file works afetr
that....go figure.

Are you trying to doc the app icon or the window icon? The is exactly 1
app icon if any, and several window icons. I personally don't like the
app icons so I tell the feind to suck them up and close. If it has an
icon title it isn't a docable icon....if a white block appears behind
when you drag to the doc, it will doc.
Read the faq, it might help.

The songs have to be recorded as 16 bit, stereo, 44100 samples
per second. (I use wavplay/xltwavplay myself). Did you do that?
If I have a directory full of such files (with a ".wav" suffix), I use
the command:
cdrecord -audio -speed=<speed of recorder> -pad -v dev=<major,minor nr> *wav
I don't know if having a CD-RW makes a difference. Hope this helps.

And the sources are available where?
This calendar system may be useful enough to someone that doesn't care
about the privacy of their schedule data, and is willing to trust a
third party that has no forcible duty of care.
For the rest of us, who might care about:
- Backup policy
- Privacy
- Service guarantees
this "web-based" approach isn't terribly acceptable.
Netscape Calendar may not have the best user interface, but does
permit keeping the data under far more careful control.
