Router and Print Server?

I was thinking about using my son's old 486 box
as router (RoadRunner).  From everything I've
read so far this is overkill :-)  So, in its spare
time could it act as a print server for my home
lan?  I'd put an HPLJ IIIP on it and may a HPLJ II.
The other machines would run Windows 95b and maybe
one linux box

Would I need a hd for spooling??? How much memory?
It's got 20mb now. Is there a security issue???

Router and Print Server?

Hi,

I use a 486 SX 25 as a print server for a HP LJ 6L.
Memory: 20MB
HDD: 170MB (a bit small; 200 or 250 are better).

Printing with raw (from Windows 9x) is as fast as from LPT1 of my Celeron.

Postscript from the 486 is not fast, but ok.

Yes (but see below).

You'd want to run Samba, then, and possibly have it accept lpd input,
too. (The Linux client could use Samba or lpd-style spooling, as you see
fit. I recommend the former for security reasons in this configuration.)

Quote:> Would I need a hd for spooling???

Probably. In theory, you might be able to use a RAM disk, but in
practice this probably wouldn't be sufficient. Not to mention the fact
that getting enough Linux on the system to host Samba might be tricky
without a hard disk. A small hard disk should suffice, though.

Quote:> How much memory?  It's got 20mb now.

That should be plenty, so long as you don't have to run X.

Quote:> Is there a security issue???

Yes. Ideally, a router shouldn't run anything but the router software.
Certainly putting major servers like Samba on the computer is not
generally advisable. You can be moderately safe if you take a few
precautions, though, and if your system has a fairly low profile (for
instance, no web server, etc.), you probably won't encounter problems.

My recommendations to reduce the security risk are:

1) Remove all unnecessary servers, including NFS, web (HTTP), FTP, mail,
   etc. This is also the source of my recommendation that you configure
   lpd to NOT accept network connections, and instead print to the box
   using Samba from your network's Linux computer.
2) Replace inetd with xinetd. The latter lets you bind services to
   specific network interfaces. You can then bind any servers you
   really must have ONLY to the internal network interface. You can
   do this with Samba by using the interfaces and bind interfaces only
   parameters.
3) Configure a packet filter firewall via a script of ipchains rules.
   http://linux-firewall-tools.com/linux/ has a tool that will help you
   build a custom firewall for your system. Use it.
4) Read a good book or two on Linux security. I've got some
   recommendations at http://www.rodsbooks.com/books/books-network.html.

1. Router/Print server & LPRng.

Hi all!

I compiled and assembled my Linux (Linux From Scratch modified)
and am pretty happy with it. But I got a problem - I can not
setup LPRng from scratch!

I am using SMC Barricade 7008BR as DSL Router/Print server.
Printing works from win laptop and another computer with RH-7.3

RedHat uses LPRng (3.8.9, in my case it's the latest 3.8.15)
but different filter scheme - magicfilter (I am trying to use
ifhp, which seems to be, I guess, better). The problem is -
I can not get anything on a printer even with REALLY limited
printcap without filters at all:

smclp:\
        :lf=/var/log/lpr.log:\
        :sd=/var/spool/lpd/%P:\
        :rm=192.168.123.254:\
        :rp=lp:

I believe it should work at least somehow!

Anyone has similar experience or working similar setup
and care to share?
