Subject: Samba, NT4.0 + lots of files problems
Date: Fri, 16 Apr 1999 12:28:26 +0200
Hello, I'm experimenting with a Linux fileserver in our company, and so far
things seem good, except that NT users have to type in their password to
reconnect to Linux shares that have been mapped as drive letters. We run
Novell 4.10 in addition to Linux, so we authenticate to those servers and NT
in one login box, then another for Linux, which is a bit annoying. Any
solutions to this?
Furthermore, I've created a software RAID0 on 2 18Gb Barracuda disks, and
shared it out for NT/95 users via Samba and Solaris via NFS. Performance
seems Ok (running 100Mbit), until we start copying lots of files to one
directory. One example is a dir with 9900 files (about 20K each). We then
unzipped a file with 9900 127byte files to the same directory (the reason we
do this is that we have a program that needs data stored this way). Whoa!
Winzip counted the files slowly, one by one while extracting it, which took
over 2 hours. CPU utilization was 100% all the time. When I do a ls -al on
the dir, it takes about 1 minute, CPU 100%. Any suggestions?
This is a bit important, because I'm planning to run a HUGE fileserver on
Linux, the specs I think I'll use are at the bottom
Please reply by mail: [EMAIL PROTECTED]
Finally info on my system:
RedHat 5.2, 2.2.4 kernel. Raidtools 0.41
Dual Pentium 200, 128Mb RAM
Adaptec 2940uw SCSI controller
2x2Gb IBM SCSI disk
1x9Gb Barracuda
2x18Gb Barracuda
Future system (if Linux can do this)
2xPII 450
512Mb RAM
10x23Gb Seagate Elite u/w SCSI disk
5x18Gb Barracuda
5x36 or 50Gb Barracuda
2 Dual-channel SCSI-controllers
2 PCI 100Mbit NICS (load balancing possible?)

Subject: Traffic control with Linux
Date: Fri, 16 Apr 1999 12:28:44 +0200
Hello,
I have a linux machine that routes ip traffic in through eth0 and out on
eth1.
I wonder if there is any software available that can limit the bandwidth
throughput depending on what ip the source/dest is using?
Like for example, if the maximum throughput is 2Mbit, one IP could
get 128kbit, another 512kbit, and a third would get 1Mbit.
Something like a bandwidth control program/patch.
Is this possible?
Sincerely,
Andreas

Hi!
I would suggest you to read the source for telnet, and the Serial-Programming
HOWTO
for more information. Anyway, I haven't dealt with any of them

Subject: Printing to a Novell 4.11 server
Date: Fri, 16 Apr 1999 17:37:48 GMT
Hello,
We have been successfully printing to a Novell 3.12 Netware server from
our Linux box for some time. We are using RedHat Linux 5.2, kernel version
2.0.36, with IPX support. However, over the weekend, the I.S. department
upgraded the server to 4.11, and now the print queue does not appear to exist
to the Netware clients.
Formally, the output of pqlist was:
[emptoris]$ pqlist -S FS-PURCH-01 -U myid -P mypasswd
Server: FS-PURCH-01
Print queue name Queue ID
============================================================

PRT135 BC02007F
PRT332 D7030023
BARCODE 3E040023
...
Now, with the upgrade, and a change in server name:
[emptoris]$ pqlist -S OSSC2 -U myid -P mypasswd
Server: OSSC2
Print queue name Queue ID
============================================================
No queues found
[emptoris]$ nwfsinfo -S OSSC2 -d -i
The server info now reads:

We know that there are working print queues defined for OSSC2 because
we are printing to it from our Windows 95-based machines.
We are starting IPX services with the standard RedHat init.d network script:
...

/sbin/ipx_configure --auto_primary=$IPXAUTOPRIMARY \
--auto_interface=$IPXAUTOFRAME
/sbin/ipx_internal_net add $IPXINTERNALNETNUM $IPXINTERNALNODENUM

Any help on this issue would be greatly appreciated.

Ok , some more information :) First, I don't think it is important, but L1 is
the slakware machine, L2 is the Red Hat .
Second, we can reach about 90% of all websites from our win95/98 machines

Only about 10% of the websites we visit have this problem

Check out the source to x10d.cm11.c or x10d.lynx.c on my home
automation page. There are other examples there such as the Heyu
code. The Heyu and x10d.cm11a.c talk to a cm11a (by x10) and the
x10d.lynx.c talks to a LynX-10 (by Marrick LTD).
To communicate with them you telnet me x10d (for example, see the
readme). Works well, especially since my main box ran out of card
slots. I use the slots on another machine to comunicate with 2
CM11A's and a weather station. I'm currently working on communicating
with my HCS II (Home Control System by Circuit Cellar).

I'm working on getting up to speed on the 2.2 kernels... I had hoped to
produce something this week but that didn't happen.
Gordon Chaffee's 2.1.x patch has been migrated to 2.2, and if you're only
masquerading one client it will do the job.
See the VPN Masq page for links.

This is true on BSD but AFAIK this has never been the case on Linux.

No, nmbd is just trying to be a good broswing citizen

browse lists.

At first glance it looks ok. I think you now need to start

Normally, on my machine I use the following commands:
1. make dep; make clean; make boot
2. copy the newly compiled kernel to the /boot directory
3. suitably modify the /etc/lilo.conf file to execute the new kernel
4. run /sbin/lilo if the kernel is a new version for reintsalling lilo
Assuming that you are using an ethernet connection, sometimes the eth0
is not turned on while rebooting. This has happenned to me once while
recompiling the kernel on a laptop. The problem was temporarily
corrected by activating the eth0 device in the network configuration
menu(on X-windows term, run netcfg).
Hope this helps.
Krishna.
