How to record traffic between Evolution and POP Server
by Jonathan Ryshpan
I'm having weird problems between my Evolution email client and my ISP's
POP server. Evolution says it can't receive a particular message; the
problem is:
Cannot get message ALwwvs4AAB//RP55HQdLMjcw/zI: Input/output
error
always with the same message ID. The ISP (ATT) says there's nothing in
my inbox on the POP server. I'd like to get some more info on what's
going on.
How can I get Evolution to record its interactions with the POP server.
Is there some environment variable or invocation option that will get
Evolution to do this?
Thanks - jon

Thanks Tony, that cleared a lot about smarttools also a lot. I always
used to wonder about how smarttools can be used to fix a hdd bad
sector. Now I learned from your mail that just writing to the bad area
of the disk will fix it because disks are intelligent enough these
days. smarttools is used for just diagnosis purposes.
Also I am goinng to put
smartctl --smart=on --offlineauto=on --saveauto=on /dev/hda in my /etc/rc.local.
Thanks again.

Intel Woodcrest Crash under heavy load with FC5 and MySql
by agraham
Hello all (especially the very technical),
I have been experiencing hardware lockups and crashes under Linux
(Fedora Core 5 latest kernel version 2.6.17-1.2174_FC5smp). The crashes
occur under what appears to be very heavy disk access and possibly
multiple concurrent access (i.e. multiple threads).
I experience crashes using Mysql (MySQL-server-4.1.21-0.glibc23) latest
4.1 stable. In this case we also have multiple threads generating a
database of approx 13-30G in size or a period of about 18 hours.
I also have experienced crashes using rsync local_disk to local_disk
copies- this creates multiple threads (unlike a simple copy - cp command
which is a single thread).
The servers are 10 x:
Woodcrest 5160 3Ghz (dual Core+Dual Xeon) (1333 FSB)
Supermicro servers

Motherboard
http://www.supermicro.com/products/motherboard/Xeon1333/5000P/X7DBP-8.cfm
(BIOS 1.1c)
16 GB FB-DIMM RAM 677Mhz - Approved and personally tested by
Supermicro USA
3ware 9550SX-4
4x500GB SATA Seagate Drives/16Mb cache.
HINTS
====
The crashes ONLY happen if we enable all 4 Cores in the BIOS (Dual core
= enabled)
Our tests run 100% perfect if we disable the second core if each Xeon!
(i.e. one core from each Xeon)
My questions
=========
Are there any "known" problems with Dual Core Xeons under load - e.g.
microcode issues ? kernel bugs ?
From the kernel perspective is there any difference in operating code
(i,e, ignoring any superficial stuff like /proc/cpuinfo stuff) for Dual
Core Xeons ?
I assumed that Dual Core would use the exact same code as SMP kernel ?
is this correct ? - I'm told it's not
Are there any special specific patches for Dual Core ? (I did notice in
RH AS 4 a change log that stated something list "improved scheduling for
Dual Core"
Things I've tried
===========
I have tried most combination of BIOS settings e.g. ACPI disabled in
BIOS, kernel parameters acpi=off noacpi noapic etc.. all of which make
no difference - the machines all crash unless I disabled Dual Core ?
I've had extensive contact with Supermicro, 3ware and now Intel - all
of which are blaming each other ?
I've also recompiled the FC5 source RPM with exact same results.
I'm told that AMD had a similar problem with one of their dual cores,
but this was fixed long ago and I assume that fix was specific to AMD
chips and would not apply to Intel due to differences in architecture.
Any suggestions for helping be solve these crash problems would be very
very much appreciated.
Thanks in advance.
Albert.

Can't print to XP printer from Fedora - SAMBA problem?
by Arch Willingham
I created a link from a Fedora laptop to an XP pro machine. I can use SAMBA to read the drives with no problem. I tried creating a printer. I opened the crate printer GUI (in gnome) as follows:
description="printer"
location="CAR"
device uri="smb://...................../CAR/hpoffice" (hpoffice is the name of the actual print share)
Make and model="HP OfficeJet 5500 Foomatic/hpijs (recommended)"
If I click CHANGE on Device uri , it pops up with an authentication box. I put in my XP user name in the form of DOMAINNAME/USERNAME and my password and click verify...it says all is OK. If I then go to the test print page, it acts like it prints. If I go to the XP machine, I see errors where it appears that SAMBA is trying to log in with the username "lp" and no domain.
Any ideas?
Thanks!

How to get fan to run?
by awrobinson-ml＠nc.rr.com
My eMachines laptop freezes in FC5. I strongly suspect that FC5 is never
turning on the cooling fan and the laptop is overheating. I don't have
this problem with FC4. Can someone tell me what package controls the fan
so I can verify and/or fix this?
Thanks!

Matrox G550, DVI and FC5
by Trond Danielsen
Hello everybody!
I have a problem with my Matrox G550 graphics card. I cannot get the
DVI output working from X. After reading the matrox forums I
discovered that I need a binary module from Matrox to get some of the
features on the graphics card working, but Matrox only got modules for
xorg 7.0.0. Has anyone tried these on FC5?
