I'm trying to do this very thing. I have Redhat5.1 and have installed
netatalk+asun. Using the nbplkup tool, I am able to list all of the AppleTalk
devices available on the network. Using, pap, I try to print a file from my
Linux host to a LaserWriter IIg. But I receive errors from the printer itself.
Once I have success printing to the printer from Linux, I plan to build a
print-queue so I can print jobs from Windows 95, too. Any experiences will be
valuable. Thanks in advance.

Subject: Caching nameserver under Linux with Masquerading...
Date: Sat, 23 Jan 1999 23:20:45 -0600
I recently got my caching nameserver working for the most part under Linux. I
have only one problem remaining. I have one Linux box that is my firewall and
my modem is hooked up to it. I also have the caching nameserver running on it.
I have a second Linux box that I do all my stuff on, surf, etc. Netscape has
no problems with DNS queries, however, I cannot use 'nslookup' it always says:
*** Can't find server name for address 192.168.10.1: Non-existent host/domain
*** Default servers are not available
Below is are resolver configuration files. Could someone please explain why
I am having such a difficult time? And YES, I read the Linux DNS HOWTO. Thanks.
-Steve
'resolov.conf'
domain sjh.net

I know it is not recommended. I just don't agree with the recommendation.
Never mind the ground loops. If they are small they don't pick up much
hum. If they are big you shouldn't be using RS232 in the first place.

Subject: 2 Linux machines 2 nics and a hub and something is wrong?
Date: Sun, 24 Jan 1999 05:26:26 GMT
Folks, I am about to go crazy here with problems. I have two machines
both running Red Hat 5.0. Both have NICs and are recognized during the
boot process. I reinstalled Red Hat on both machines to get a fresh
start. During the install I chose to set up networking for each
machine.
I want machine one(M1) to be able to connect to a cable modem later on
so I want it as a gateway.
M1(linux1.blank.net) M2(linux2.blank.net)
IP = 192.168.9.1 IP = 192.168.9.2
netmask = 255.255.255.0 netmask = 255.255.255.0
gateway = 192.168.9.1 gateway = 192.168.9.1
domain = blank.net domain = blank.net
These machines are both connected to hub. I cannot ping one machine
from the other but they can ping themselves and their dummy interface.
If I want M1 to be a gateway later on, setting the gateway IP to
192.168.9.1 is correct right?
Why can't these guys ping each other? I tried adding each of them to
the others routing table but that didn't work or I didn't do it right.
When I do a 'route -n' it shows that the entry is there.
Can somebody tell me what I'm doing wrong?
Thanks

Sure sounds link a interupt of DMA conflict. Most likely interupt. I would
think the best places to look would be the two nic cards involved and the
scsi system. Two of them and maybe all three may have the same Interupt
setting.

Assuming your Linux/Samba machine had a static IP address then you could
specify the share as "\\192.168.X.X\share" if "192.168.X.X" is its
static IP and "share" is the winshare name. You could use "tcpd" and
edit the file "/etc/hosts.allow" to set up access lists so only certain
hosts can use the share. Since Windows file sharing is bandwidth
intensive, unless you have a fast connection, you probably will notice a
slowness. This may be a security risk too, since you will be allowing
remote hosts access to your internal services.
Note also, that 192.168.X.X could be replaced with a machine name if
that IP has a DNS entry.
If the Linux/Samba is on the Local LAN, then it would be under Network
neighborhood (assuming you set Samba up correctly). The machine you list
should have no problem with it. I would make a decent swap partition
though, say 64MB as well.
