Use memtest instead. Or try to build a kernel. If it barfs
out with a "sig 11" error, then either your RAM is damaged,
the processor overclocked or the cooler fan not working.

Subject: Samba 2.0.7/RH7.0 and W2K
Date: Mon, 12 Feb 2001 07:37:24 +0200
I have Samba 2.0.7 running on RH7.0.
I have a dual-boot (W2K/WinMe) PC on the same LAN. I gave each OS its own
computer name and IP. Both OS's and the Linux have both IPs and host names
appearing in their HOSTS file.
Both W2K and WinMe can see and access shared directories on the Linux via
Samba wioth no problem (I enabled un-encrypted passwords on both).
However, only the WinMe can succesfully logon to the domain.
I get the following error messages: "Failed due to process number out of
range" or "credentials already exist".
What am I doing wrong?

Did you try anything at the grub prompt?
If it's anything like lilo (not that it should or shouldn't be - I've
never used grub myself), you type in the OS name or kernel name you want
booted up.

To my knowledge (dec-2000) you can configer Reiserfs with Sw-raid. It may
work, but may produce spurious errors. If you have valuable data (otherwise
you would not want raid) be cautious...

During the linux boot.. BIOS sees it just fine, I can go into the DPT
bios and see all the drive specs, etc.. No hardware setup problems..
When the i2o driver tries to initialize, it can't see the raid.. I can
get 2G with no raid, or 960M (or less) WITH the raid, so I'm positive
it's a conflict.. The hardware is set up fine, because it works under
lower ram conditions.. There's 10 18G drives that show up in the os as
1 giant ~140G drive.. It's all HW raid, so the os doesn't even know the
difference.. It just thinks there's one big scsi drive there.. When I
put the
append="mem=2048M"
(or anything higher than 960) line in lilo.conf and run lilo, I get a non
descriptive 'i2o init failure' msg, then since there's no drive/fs's, I
get the 'fix your fs's' prompt and it stops the rest of the startup
scripts & dumps me to the prompt..
I've been looking around, and found stuff about old linux versions and a
960M limit on ram.. I wonder if this driver was made before the limit
was broken, so the driver assumes that 960M would be a good place to put
itself in ram, then 2G of ram comes along and blows it up.. I dunno..

Subject: Re: How to get Users to create files with another group as owner??
Date: Thu, 15 Feb 2001 13:57:36 GMT
Dan,
The manual page for chmod explains it, but very tersely.
Basically, if you have a directory called "foo" you would do:
chmod g+s foo
Then the permissions on foo would look something like:
drwxrwsr-x ...
(assuming the other permissions were already set up as you liked).
Note the 's' in the group field. In octal, these permissions
are 2775 (the suid bits are in the highest order octal digit).
Now, any time a file is created under "foo", it will get the same
group assigned regardless of the user's default group.
To ensure that files and subdirectories have the correct permissions,
then you need to make sure the users have a proper umask (if doing
operations under Linux), or that Samba config is set up with the
permissions you want (if accessing from Windows clients).

Point well made. This is a home project though, not a serious production
environment. As such, I figured it would be to my advantage to learn
sendmail administration somewhere along the line given the ubiquity of that
setup. It's just too common to ignore, and at some point, I will be asked
to set up a production mail server at work. Maybe it'll be qmail, maybe
not.

This is correct. I did however download Life with Qmail and it makes
mention of qmail-pop3d, which is a fledgling qmail pop server. It's a
seperate download and doesn't seem to have the support that others do. And
it's POP, not IMAP.
It is the POP/IMAP that's giving me trouble. Or maybe I just have DNS
screwed up? I can retrieve and send mail to/from the Linux box via these
utilities, but I cannot get Outlook from my Windows machines to connect to
the IMAP devices.
I have tried both IMAPd and Qpopper. Both run fine, but still Outlook
errors. I can ping the Linux box from Windows. I can telnet to the Linux
box from Windows. But I can't collect mail. I have now downloaded Univ. of
Washington IMAP and all appropriate qmail patches, and installed that last
evening. Maybe this will do the trick?

I have it working that way but it does waste a process. It is just that
every other Unix like OS I have used (AIX, Solaris, SVr4, SCO, Unixware,
Xenix, etc) using sh or ksh allowed this and I was wondering why bash under

Subject: Re: ksh script problem: pwd works differently for ksh then linux binary file
Date: 15 Feb 2001 14:58:27 GMT
I went to the trouble of installing pdksh (I use ksh93) and
could not reproduce your problem:
#!/usr/bin/pdksh
cd
[[ -d td ]] || ln -s /usr/local/bin td
cd td
whence -v pwd
pwd
pwd -P
echo $PWD
$ tb
pwd is a shell builtin
/home/dam/td
/usr/local/bin
/home/dam/td
So, the question is, what are you doing wrong? As you can see,
pwd is a builtin. Now, it is possible you have ENV set and your
ENV file (.kshrc?) is doing something screwy to cause this. To
make sure that isn't happening, change the shebang to
#!/usr/bin/pdksh -p
You might want to post the script.
