I got one of those with a computer, but drivers are limited to certain
older kernels, and it didn't even work very well in Windows (broke up the
music that my free MSN acct plays while dialing). Fortunatly I had an old
real ISA PNP modem laying around that works. I have not tried a PCI modem
so I am not sure how they work.
Your best bet is to get an external serial modem that will work with any
OS. The Diamond SupraExpress 56K external I use on another box has worked
flawlessly with default settings in Linux, FreeBSD and Windows.

When you telnet etc. in it tries to resolve the address of the client
into a host name. Clearly it can't. When you don't have any DNS enabled
it has nowhere to go so fails instantly. When you do it has the whole
Internet to ask so it does, and waits for a while (typically ~90s)
before giving up.
Ensure that the server can resolve its clients' addresses, either via
DNS or /etc/hosts. The latter is probably easier if you don't want to
set up a local DNS. I'm not sure what Caldera uses to define resolution
order, it's often /etc/nsswitch.conf or /etc/host.conf. Check your
documentation. Put "files" or "hosts" before "dns".
You don't say whether "your DNS servers" are on your LAN or at an ISP.
If they are on the LAN then the best solution may be to get the DNS
admins to add your client machines to the local DNS, provided they are
cooperative.

If your winmodem is not one of the supported models your will
either have to write your own driver or replace the modem with
one known to work.

If you have a static IP and hostname, it is best to use that for the
system. It makes sendmail, apache, etc. much easier. You can always put
whatever you want for a return address in your mail reader.

It can have as many names as you want (DNS or /etc/hosts), usually at
least 1 for each interface. But using an internet name as a hostname is
best when possible. For smb.conf see 'netbios name' and 'netbios alias'.
Samba can answer to more than one name (handy for dhcp).

Remove the alias or masquerade setting from your sendmail configuration
and set your box's hostname to wookie.demon.co.uk. If you use the
'hostname' command to change it instead of linuxconf, you also have to
change it in one of the startup scripts (/etc/sysconfig?)). If your
interface with that name is not always up (ppp), you can assign that name
to 127.0.0.2 in /etc/hosts.

I don't know the answer I'm afraid, but I have a small machine with a
1542 with /usr on the SCSI disk (/ is on an IDE as the 1542 isn't
bootable), using an initial Ramdisk containing the aha1542 module. I
must admit that I thought that the reason I had to do this was because I
also have my swap partition on the SCSI (the IDE is only 120M). I didn't
think /usr needed it. I havn't tested this mind. My kernel is 2.2.16.
My 1542 is using IRQ 11 and I/O 330. I'm not exactly sure what the MB
is, this machine was cobbled together out of spare bits. This is a
simple machine used as an ISDN router/DNS/mailserver, it only has the
SCSI card, an RTL8139 ethernet and an AVM Fritz! PCI ISDN card. No sound
cards or such to screw things up.
You might try the Ramdisk approach to see if it works for you.
I have come to the conclusion (with a little help from the more
experienced) that Ramdisks are best avoided so had been thinking to
change this setup to the one you are attempting (I have already done
this on the large machine with a 2940). So I will exercise a little
caution in this, and follow this thread.

Subject: Re: ...dup2: Bad file descriptor [FAILED] .../dev/null: Read-only file system
Date: Wed, 9 May 2001 14:57:48 -0700
Hi,
Anyone have any ideas how to fix this? See original post for system setup
info.
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!

This could be the 1024 cylinder problem. Make sure you install the LILO
boot loader on the disk's MBR and not a partition's boot sector (eg.
/dev/hda and not /dev/hda1).
Also, make sure the parititon containing the /boot directory is not too
far up on the disk. Tghe best thing is to create a small partition - say,
64 MB - right at the beginning fo the disk and configure linux to mount
this as /boot. That way, the kernel is below the 1024 cylinder limit.

If this dosen't solve the sounds problem then you need to look at /var/log/dmesg
to see if the card is detected with out any problems. You should see a line
showing the module being loaded into the kernel. Then later in the file you
should see the card being detected and loaded with its IRQ#, Mem Range, and DMA

No, LILO prints LILO on the screen to indicate each stage of startup,
therefore LIL actually gives you the error message that you should be
able to find in the LILO documentation.
As the other poster suggests it could be a BIOS problem - so maybe you
could locate /boot in your first primary partition.
Also I have heard good things about the GRUB bootloader.

you can use 'linuxconf' or 'diskdrake' to figure out what your windows
partition is (probably /dev/hdc2 or something like that)
then you need to put an entry in your /etc/lilo.conf that points to that
partition for booting.... I dont' remember the syntax off the top of my
head, but you can do a google search for "dual boot howto" or "windows
lilo" or something like that to figure out the syntax.
after you've added the entry, run 'lilo' to read in the new lilo.conf
file.

Hasn't changed even if ms claims that win2k can be installed in any

Made a mistake for a "default" auto-install and win2k installed on my

I have nt4 and win2k and linux :-( Couldn't do "update/upgrade" as C:

wierd.... but you shoudl re-install the mandrake8.0 kernel anyhow, it's
a bit buggy.... 2.4.4 cleans up some locking problems.
you might try turning off APM in the kernel.... it _might_ be the
problem, but I'm just guessing.
try a new kernel and see if that helps any.
