Re: [seul-edu] Re: HELP!



Thanks for the replies.

LP:
    I tried the URL you sent, but it was nothing new. The Laserjet 4 in the
classroom is connected to the parallel port of the server, and it works just
fine from there. That URL was about setting up the server. My problem is
that the clients keep saying they can't print because the daemon won't let
them. However, both the client and the server have the lpd daemon running.

Bill:
    My network has 7 machines, with dummy IP numbers of 192.168.0.100 (the
main fileserver, alias "teacher") through 106. The clients are aliased pc1a
through pc6a. Any of them is able to ping any of the others just fine. Also,
all of them successfully mount teacher's filesystem via NFS. Likewise, any
of them can mount the CD drive or /usr of any of the others (set up NFS as
/mnt/remcd1 or /usr1, etc.), except the others can't mount pc6a. This is the
one machine connected to the Internet through a separate NIC, which I hope
to turn into a gateway.
    I'm not worried so much about the firewall yet, because right now I'm
trying to transfer a large tar.gz file downloaded from Adobe from pc6a onto
teacher. However, whenever I try to mount or do a rlogin to pc6a I get a
message to the effect that "errno = connection refused by host." Since it
used to work before I installed the second NIC, I even tried reinstalling
Linux -- to no avail.
    The /usr directory on pc6a is read-only via NFS, but all I need to do is
copy the tar.gz file from it, if only I could mount it. I also set the /home
directory on teacher as rw for all clients so I could try sending to it, but
when I try to do so from pc6a I still get a message that I don't have
permission. ?????
    Regarding masquerading: I used Linuxconf to tell every one of the other
machines that 192.168.0.106 (pc6a) is the default gateway. They don't seem
to care. Is there someplace where I am supposed to tell them what its "real"
internet IP on the other NIC is? It's a static address, though it connects
as DHCP. Ifconfig says everything is fine, and pc6a accesses the net just
fine, but the others don't seem to know it's there.

Bob:
    The printcap on teacher looks exactly like the one you sent. I will try
manually creating the one you sent on pc6a tomorrow. Printtool's output has
several differences -- see below. Thanks for the references on firewalls.
I'll check them out.

Rick:
    I replied to your previous message 9/7. Guess you missed it. The
difference between what Bob suggested vs. what printtool created on the
client is that its printcap reads
lp:\
    :sd=/var/spool/lpd/lp:\
    :mx#0:\
    :rm=teacher:\
    :rp=/var/spool/lpd/lp:\
    :if=/var/spool/lpd/lp/filter:

BTW, hosts.lpd on teacher is OK - it contains the alias of every one of the
machines in the network.
    I've followed every suggestion I got as of this morning, to no avail.
I'll try Bob's tomorrow.

Thanks,
Dave Prentice
