I've been where you are now.
1) First, try upgrading your serial driver (see
http://serial.sourceforge.net/) to at least 5.05.
2) If that doesn't work, search http://groups.google.com for your modem and
linux issues.
3) If those don't work, try upgrading your kernel to 2.4.
My issue was compounded by a PCI IRQ conflict between my modem and my UDMA66
controller. I could either patch my 2.2.16 kernel or upgrade to 2.4 to resolve
that. If you have ATA-66 or ATA-100, this may also be a problem for you.
Let me know if you need more assistance.

And since your /proc/interrupts doesn't show "serial" next to IRQ 3 like it
should, it seems that you have IRQ sharing problems. Try the serial driver
upgrade and if that doesn't do it, try the kernel upgrade.

Subject: HELP! Kamakazi Shell Script Whacks System To Death! /etc/rc.d/rc.sysinit
function
Date: Wed, 9 May 2001 21:25:28 -0700
[ reposted from compos.linux.setup ]
Hi all,
I'm looking for help with what maybe is a broken shell function, called
"action", listed below. I can manually run its input "STRING" command and
see a full /proc directory by typing,
`mount -n -t proc /proc /proc && ls`
but the same command fails when the shell script, /etc/rc.d/rc.sysinit
runs:
`action "Mounting proc filesystem" mount -n -t proc /proc /proc.
I tested this shell script manually again by loading the shell script
"action()" listed in /etc/rc.d/init.d/functions, which reads as:
# BOOTUP=color on this RedHat 6.9~7.0 system
# for setting [SUCCESS], [FAILURE], etc. to pretty colors
if [ "$BOOTUP" != "verbose" ]; then
INITLOG_ARGS="-q"
else
INITLOG_ARGS=
fi
# Run some action. Log its output.
action() {
STRING=$1
echo -n "$STRING "
shift
initlog $INITLOG_ARGS -c "$*" && success "$STRING" || failure "$STRING"
rc=$?
echo
return $rc
}
Nothing fancy. Just returns the error which I am trying to fix:
Mounting pro filesystem dup2: Bad file descriptor
[FAILED]
Anyone have any ideas how to fix this shell script "action()" function?
See original post in comp.os.linux.setup for system setup info, which
mentions my debugging efforts so far.
I hazard to guess that the system bootup scripts are failing due to a
non-fscked, >>> non-mounted /proc read-only filesystem <<<. dup2 errors
result
because rc.sysinit finds that the /proc directory is empty. The system will
not proceed to multiuser unless it has a clean (fsck'ed) filesystem. Running
top and df fails as well since these programs depend on pulling information
from the /proc directory, stating "Error: /proc must be mounted To
mount /proc at boot you need an /etc/fstab line like: /proc /proc proc
defaults In the meantime, mount /proc /proc -t proc
Looking at the dup2 error, "Bad file descriptor", it seems that since proc
wasn't mouted there are no virtual files to get a valid file description.
And thus, the error, "Bad file descriptor".
I'm not sure of the booting sequence of programs other than what the rhl
guide mentions 1) Lilo 2) Kernel 3) Init 4) rc.sysinit. But since the
filesystem remains "Read-only" it may be that there is a broken script
between Init and rc.sysinit. I think maybe that this has to do with mounting
the system read-only first for auto-fscking and then remounting the as
writable so that rc.sysinit can mount and get file descriptors from the
/proc directory.
What scripts are run between Init and rc.sysinit? Before rc.sysinit mounts
/proc it does:
1) # Rerun ourselves through initlog
if [ -z "$IN_INITLOG"]; then
[ -f /sbin/initlog ] && exec /sbin/initlog &INITLOG_ARGS -r
/etc/rc.sysint
fi
2) # If we're using devfs, start devfsd now -- we need the old device names
[ -e /dev/.devfsd -a -x /sbin/devfsd ] && /sbin/devfsd /dev
3) # Set the path
PATH=/bin:/sbin:/usr/bin:/usr/sbin
export PATH
4) # Read in config data.
if [ -f /etc/sysconifg/network ]; then
. /etc/sysconfig/network
else
NETWORKING=no
HOSTNAME=localhost
fi
5) # Source functions
. /etc/init.d/functions
6) # Print a banner. ;)
echo -en "\t\t\tWelcome to "
[ "$BOOTUP" != "serial" ] && echo -en \\033[1;31m"
echo -en "Red Hat"
[ "$BOOTUP" != "serial" ] && echo -en \\033[0;39m"
echo " Linux"
if [ "$PROMPT" != "no" ]; then
echo -en "\t\tPress 'I' to enter interactive startup."
echo
sleep 1
fi
7) # Fix console loglevel
/bin/dmesg -n $LOGLEVEL
# Mount /proc (done here so volume labels can work with fsck)
action "Mounting proc filesystem" mount -n -t proc /proc /proc
And here's where the dup2 errors occur. The only place dup2 occurs in /etc
is in /etc/ltrace.conf: ; unistd.h ... int dup2(int, int); The comment
occurs in /usr/include/unistd.h: /* Duplicate FD to FD2, closing FD2 and
making it open on the same file. */ extern int dup2(int __fd, int __fd2)
__THROW;
Any help is appreciated!

Subject: How to route email locally and externally?
From: [EMAIL PROTECTED] (Mark Johnson)
Date: Thu, 10 May 2001 04:59:51 GMT
Is it possible to configure our linux box such that it can determine
whether to route an email locally or out to the relay host?
For example, our company is provided by our ISP a domain name
"foobarco.com" and 15 email address: [EMAIL PROTECTED], [EMAIL PROTECTED],
etc... All the employees run Win98 and Mac9 but we want to run linux as a
file server and web server and possibly an email host.
What we would like to do is when joe emails mary we would like that email
to not out out to the ISP and then right back in, instead it should just
realize that Joe and Mary are local users and deposit the email in there
linux home account which they can access using their regular SMTP/POP3
email client. However, if Joe emails [EMAIL PROTECTED] then linux will
relay the email to the ISP and everything continues as regular.
I know that I could this easily by just having an internal and external
email accounts (i.e. [EMAIL PROTECTED], and [EMAIL PROTECTED]) but the
users won't like this. Instead it needs to be transparent from the user,
however, they will have to understand that they can't access the "office"
email from home.
Anyway, any suggestions here? I'm kind of newbie with all this...
thanks for your time!
NOTE: we do not have any window's domain controllers. I was thinking of
using SAMBA for authentication and etc.., currently, everyone is on a plain
old Win98 workgroup.

I have Linux RedHat 7.0 installed on a PC. The pc loads xdm
automatically. If I logon through X my env does not reflect the
variables in the /etc/profile. If I do the Ctrl-Alt-F1 to logon, then
the env reflects the contents of the /etc/profile. Does this make sense?
If so what is the xdm equivalent of /etc/profiles.
Any help would be greatly appreciated.

We are looking for a Linux moonlighter in the Orange County area to help
us transfer a DOS batch file based industrial system to a Linux based
system. This is NOT a regular position and is not suitable for someone
who needs something to pay the rent. Payment will be in the form of very
low priced stock options in a public company that will be profitable by
August . Estimated time required to do the job is 50 hours depending on
your experience. Can lead to more contract work in future.
I don't care about qualifications or how old you are. Students and
"hackers" welcome. If you know lot about setting up Linux machines,
specially script based units and can write the Linux equivalent of DOS
batch files, I can use your help. Experience with Linmodem software
(using a Winmodem under Linux) and getting PCI sound cards to work under
Linux will be helpful. We will supply dedicated machines for you to use.
We prefer to deal with someone who lives in Orange County, California or
nearby (LA or RIverside county) as there will be times personal contact
will be needed.
Call Dan at 714-420-7535 or after 5:30 in the evening at 714-637-5366.

Sure thing. Using Postfix, I have the following in /etc/postfix/main.cf:
mydomain = my.domain.de
mydestination = $mydomain
masquerade = $mydomain
relayhost = smtp.my.provider.com
and a regular account for all (mail)users. This accepts all mails to
[EMAIL PROTECTED], rewrites From: lines to [EMAIL PROTECTED] for outgoing
mails and relais everything _not_ addressed to my.domain.de via my ISP.
