You don't need a patch, it should already be in there. Enable
CONFIG_IP_MASQUERADE_ICMP=y
under Networking Options and recompile.

NOT, the anti virus should run on incoming files to the network, either
as a CVP or proxy between the LAN and the FW. Yes, having AV on the
desktop keeps floppy type viruses from propagating inside the network
but inbound files from the internet should be scanned in 1 place and
updates need to be done MUCH more than every month or so!

Hi!!
Just look at these two sites:
http://www.sfu.ca/~yzhang/linux/samba/index.html
http://home.talkcity.com/MigrationPath/maguai/samba.html
They helped me a lot to get my Samba-Server running (it is running since
today :-) )....
Mail me if you want my smb.conf!!!!

well:
- 'null passwords = yes' in [global]
- turn encryption on (4.4.2.2 on my web-page should help)
- 'smbpasswd -n userid' (I think, look at smbpasswd's man-page) to clear the
passwords you want clearing.
Your /etc/passwd passwords are still there but Samba clients can come in
without a password.
Or: set up a guest-account with no password,
force guest.

If I understand what you want, this is what the combination of Samba and
Windows' standard networking does (assuming you're using Windows; if
you're using Macs, look into Netatalk; and if you're using other UNIXes,
that's standard with NFS and lpd). If you're looking for something that
Samba doesn't do, please post more details.
> 2. Mail / Fax and web access solution
This is a bit vague. Certainly Linux can be used for just about any
standard mail transport task, as it supports both SMTP and POP. There are
also plenty of native Linux mail READERS, so you could set up a Linux box
and have people read their mail on that machine.
As to fax, Linux has fax packages, both send and receive. There are an
assortment of ways to fax using a fax modem connected to Linux from a
networked computer (UNIX, Windows, Mac, whatever).
As to "web access," that's quite vague. Linux can be used as a web
server, there are several web browsers available for it, and it can be
configured as a router or with IP masquerading to let local clients browse
the web with Linux as an intermediary.
Again, if there's something specific you want that you believe Linux
doesn't support, please be more specific about it.
> 3. Automated Backup solutions
If you want to back up Windows 9x boxes, one effective solution is to use
Samba, and in particular the smbtar utility. This will back up exported
Windows filesystems directly to a UNIX-style tar archive. Restoring a
full backup is a bit trickier, since you've got to have an OS running that
understands SMB. It can be done with a Zip boot disk, though (I've done
this), or (I'm assuming) with a custom Linux boot floppy set. Windows NT
could be trickier to restore because of its use of NTFS, but I'm sure it's
possible (I've got to look into this soon myself). Mac backups are more
problematic, as near as I can tell, but I've done it in a non-automatic
way using Apple's Disk Copy utility.
There are also commercial backup programs that claim to do much the same
thing, and more, but I've never tried any of them.
> 4. A network client for the workstations.
If you mean a way for Linux to access Windows shares, that's part of the
Samba package. The Linux kernel also includes some support for this. You
can use Windows filesystems as if they were local Linux filesystems, if
you like. You can also print to printers attached to the Windows
computers. The afpfs package accomplishes much the same for Macs.
If you mean client software for the Windows machines to allow it to access
Linux stuff, that's built in if you use Samba on Linux. If you want to
avoid using Samba, there are Windows NFS clients available, but I've never
used them.
If you mean something else entirely, please be more specific.

Hmmm, the main issue at the moment seems to be that mail in the queue on

it would just be a case of adding an entry in the hosts file on the linux

Subject: Installing Netgear FA310TX card
Date: 16 Jul 1999 14:35:39 GMT
I am trying to install a Netgear FA310TX card on Red Hat Linux version 4.2.
On the same machine I have Win-95 working fine with the card.
I followed the instruction provide by Netgear.
Compiled the tulip driver and cp it to /lib/modules/2.0.30/net/tulip.o.
When I type depmod -a it gave a message:
Unresolved symbols in module /lib/modules/2.0.30/net/tulip.o
The machine is a 133MHz clone with 6G of harddisk, 64M of RAM.
Does anyone have any ideas?

Subject: Were is /etc/dhcpc
Date: Fri, 16 Jul 1999 14:01:00 GMT
I have an ADSL hookup at home with a server running RH 6.0 and I just
configured the firewall script from the Mediaone website. After
following the instructions for installing the "rc.firewall" script into
/etc/rc.d/ then installing the "dhcpc-done" script in
/etc/sysconfig/network-scripts/ and trying to run the "dhcpc-done"
script, I get an error message that says "DHCP is configured, but ifup
may have timed out.". The portion of the "dhcpc-done" script that
contains the error reads like this:
# dhcpc-done
# RedHat Versions thru 5.2 use /etc/dhcpc/hostinfo-eth0
# Future releases (RedHat development releases) use
/etc/dhcpc/dhcpcd-eth0.info
if [ -f /etc/dhcpc/hostinfo-eth0 ]; then
hostinfo="/etc/dhcpc/hostinfo-eth0"
elif [ -f /etc/dhcpc/dhcpcd-dhcpcd-eth0.info ]; then
hostinfo="/etc/dhcpc/dhcpcd-eth0.info"
else
echo "DHCP is configured, but ifup may have timed out." >
/dev/console
exit 1
fi
As you can see it calls for "dhcpcd-eth0.info" file in a directory
called /etc/dhcpc/. Thats when I found out that I did not have a
directory called /etc/dhcpc/. I checked my services at start up and
dhcpc is listed.
Am I missing something here or do I need to install something else?
Thanks in advance!!

It is a module. But normally it should be loaded when the network-script

Pretty good chance that your linux box isn't listening for those calls
from the 216 boxes. Or that the 216's aren't listening on your
broadcast IP. But my money is that its on the linuxbox and it is a
mask/broadcast prob.
In your various config files you can have more than one (in most
cases) on a single line seperated by a space i.e.
foobar xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy
Can't say this is the prob, but hey its a thought, right? <G>
