My system locked up under X and Win95 and WinNT every now and again, until
I unplugged the mouse and plugged it back in with a big nudge to make sure
it's secure. No problems since.
We computer types sometimes overlook the simple problems, especially if it
makes you go buy a new toy. (I really like my IBM ScrollPoint, BTW!)

Subject: pppd with demand dialing / keeping packet that opens connection
I'm setting up a machine with pppd demand dialing, and I seem to recall
someone on the list awhile ago mentioning that there was a /proc/... file
you could echo 1 > to that would tell the kernel to save the packet that
caused the connection to come up. Anyone remember what this file was? My
goal is to allow the connection attempt that brings the modem up to go
through without the user having to hit reload. I searched the list
archives, and could not find this message. Thanks!

That's ip forwarding, I've already got that working. Somebody mentioned
something about there being a different file that will actually save the
packet that brings up the diald (well, in this case, pppd dial on demand)
connection and will send that packet when the connection comes up, instead
of just forgetting it as usually happens. This way, whatever request
brought the connection up will be completed. I just have to deal with some
clients that can't understand the concept of having to do one connection
attempt to the web site / e-mail server to bring the connection up, and
then resending that connection attempt to actually establish the
connection. Any ideas?

I don't know about saving the acutal packet, but there's a debugging
option to turn on the logging of matched filter rules...

Subject: dual ethernet module loading
at the recent installfest, I got my new firewall-to-be set up with 2
ethernet cards (3c509s). it took several advanced people some time to figure
out that we needed to put '/sbin/modprobe 3c509' at the end of
/etc/rc.d/rc.sysinit, to make sure the modules were loaded.
I decided to upgrade the box to RH 6.1. (foolish me).
since then, I can't get the modules to load at boot time.
I put '/sbin/modprobe 3c509' in rc.sysinit; and at boot time I see
"can't locate module 3c509"
trying the same command from the command line after boot, also gives
"can't locate module 3c509".
trying '/sbin/modprobe /lib/modules/2.2.12-20/net/3c509.o' gives 'no
dependendcy information for module /lib/modules/2.2.12-20/net/3c509.o"'
so I tried doing a 'depmod -a'; which generated a modules.dep file
(just like the /lib/modules/2.2.5 directory had). still gives the same error.
I can get the modules to load if I do:
insmod 3c509
ifup eth0
ifup eth1
but I tried doing this at boot time (putting those lines at the end
of the rc.sysinit file); and it always gives a "resource busy" error (or
something like that) at boot time.
what's wrong here?
would putting some boot parameters into lilo help? (I wouldn't think
so, but...) if so, what should they be?
thanks,

Subject: Re: [TCLUG:9366] dual ethernet module loading
What does `cat /etc/conf.modules` reveal about your adapters?
At boot time, the RedHat init scripts de several module checks including
a `depmod -a`. Because RedHat places their modules into a nonstandard
location (kernel-version-RPM_package_release), traditional depmod searches
don't always work (just take a look at /etc/rc.d/rc.sysinit). In any
event, you should be alright as long as the depmod-a can successfully
update /lib/modules/`uname -r`/modules.dep.
A quick fix would be to search for replaced files from the upgrade
(provided of course that you did an actual upgrade, not a freah install of
6.1). Look for anything ending in .rpmsave. Do a diff against the
replaced version to see if your modprobe magic was somehow messed up by
the upgrade.
Your best bet is to compile a dedicated kernel (this is good practice
for production boxes, not to mention general Linux use anyway). Compile
the drivers for your adapters into the kernel directly and use lilo
parameters to initialize both adapters (Note: you will still need to `make
modules` though. There are several masquerading kernel modules that must
be arbitrarily loaded).
Good Luck

Subject: NIS problems on a Sparc64 running RedHat
Hey,
I'm trying to get NIS to authenticate a user on a Sparc64 running RH6.
Basically, it authenticates all the users currently in the NIS tree, but
when I add a new user, it will not authenticate on the Sparc, but
authenticates on every other machine. There is nothing in /etc/hosts.deny
that would deny it, and all the pam and login configuration files look
fine. The weird thing is if I delete a user from NIS and add them again,
that user can still log in. Any ideas?
