Checking sendmail.cf file at boot time
by Robert L Cochran
In an earlier posting I made on the Shrike list, I mentioned it is a
good idea to turn off mail relaying in sendmail. Someone responded that
the default sendmail implementation from Red Hat only listens for
connections on the local host, anyhow, so in effect why bother?
The best answer to that is that a substitute sendmail.cf file could be
inserted to the system maliciously at some point. You should not just
assume that sendmail is running with the actual Red Hat defaults, in
other words.
Substitution of sendmail.cf can be done without disturbing the
/etc/mail/sendmail.mc file. Then restart sendmail. Presto! Without quite
realizing it, the user's sendmail is listening for connections and is
suddenly an open relay.
What I do is that if sendmail is active on my system, I always manually
edit sendmail.mc, run it through 'make -C /etc/mail', and restart
sendmail to use the new sendmail.cf file. That way I know I generated
the sendmail.cf file using the options I want (rather than praying the
Red Hat defaults are working.) I could go a step further and write a
cron script to check the date and times of these files every now and
then and email me if they change unexpectedly.
So I'm thinking that what would be nice is functionality in both the
initscripts and perhaps some other service which runs during normal
uptime which checks whether sendmail is installed and if so, whether
certain options considered to be high risk are turned on.

Graphical boot
by Terry Linhardt
Sorry if this is redundant. But, I haven't seen any discussion...
The graphical boot...is it supposed to work with the newest beta? It
appears to be configured in /etc/sysconfig/init...but certainly nothing
"graphical" occurs. Any feedback.
Thanks...Terry

viewing samba in nautilus unreliable
by Pavel Rosenboim
Hi,
When I open 'network servers' menu, sometimes it works just fine, but
sometimes it just displays empty nautilus window. In this case refresh
doesn't help. I also got a crash once during this. Anyone else see similar
behaviour?

more system failures with Severn.... (on an Athlon)
by Elton Woo
I don't have kmail installed (this time) ... third *successful* install.
Instead I have to use Mozilla mail. Starting Evolution, and I get
this error message:
" Cannot activate component OAFIID:GNOME_Evolution_Mail_ShellComponent :
The error from the activation system is:
Unknown CORBA exception id: 'IDL:omg.org/CORBA/INV_OBJREF:1.0' "
Evolution then loads, but without it's default contents and folders.
Also, sendmail is VERY SLOW to load, so the load process (even the graphical
one) 'hangs' for about 2 full minutes when almost at the 80% mark .... I'm
gauging the "80 %" as a "guesstimate" of the visual completion bar.
bugs? you betcha! ... and to think that some in this list are already
running the
2.6 prerelease kernel. I guess this means serious problems for the AMD
users
here. Compared to most of 'em on the list, I'm running a fairly "old"
system
(about 4 years): AMD Athlon, nVidia (3 D Labs) card, and Viewsonic 17.
Before my last crash and burn, I tried installing the nVidia drivers, and it
could not create the needed module. Sounds logical though, since I imagine
there would be some need of updating or patching to support the present
kernel in Severn.
Elton.

CDROM confusion
by Gerry Tool
I am going nuts trying to figure out how to get kudzu to stop trying to
mount "extra" cdrom drives. I have two drives, a cdrw on hdc and a dvd
player on hdd. I have added hdc=ide-scsi hdd=ide-scsi to my kernel line
in grub.conf. I have created links /dev/cdrom linked to /dev/scd0 and
/dev/cdrom1 linked to /dev/scd1.
I have changed /etc/fstab to read
/dev/cdrom /mnt/cdrom udf,iso9660
noauto,user,ro 0 0
/dev/cdrom1 /mnt/cdrom1 udf,iso9660
noauto,user,ro 0 0
trying not to use kudzu for the cdrom drives.
When I reboot, kudzu insists on creating new links /dev/cdrom2 to
/dev/hdc and /dev/cdrom3 to /dev/hdd, and adding lines as follows to
/etc/fstab.
/dev/cdrom2 /mnt/cdrom2 udf,iso9660
noauto,owner,kudzu,ro 0 0
/dev/cdrom3 /mnt/cdrom3 udf,iso9660
noauto,owner,kudzu,ro 0 0
This all worked fine when I set it up this way in RHL8.0 and RHL9.
How can I resolve this?
Thanks in advance.

RE: ACPI/PCMCIA, cdrom/smartd, VESA settings issues with laptop (UPDATE)
by Andrew Lofthouse
Wow. Must have been a late night when I posted the
last message. After having some time to mess around
with system settings, seems that most of my issues
were fairly small. This is what I've come up with:
1. I've always had ACPI problems with this laptop
(with Linux). I was hoping this would work, but...
2. The laptop is about 4 years old, so the harddrive
isn't SMART capable, hence the problems with smartd.
This, though presents a problem for users non-SMART
drives. Since smartd is enabled by default, and it
causes drive errors that then cause Gnome to hang
during login, how is a fairly inexperienced user going
to get past that hurdle?
3. VESA settings (such as vga=788) depend on the order
of kernel options (?). I now have graphical boot
turned off and kernel options as "acpi=off vga=788" in
grub.conf. It seems to also work with graphical boot
turned on (but on the first console).

My understanding was that the last time Red Hat OS engineering tried
it was a before a number of ext3 bugs were fixed. I don't know of any
current problems with the htree code.
