campin,
I just wanted to add to the root's reply. I would suggest looking at the
"physical" aspects of your network. By virtue of your observation that
you see "blinking" lights on the card during the ping this suggests that
there is a problem with the wire or as root suggested perhaps the
connector the card is trying to go out on. Also, don't forget to
terminate the connectors on the ends of your 10Base2 net as this can
create line problems with out them. You also probably already know this
but you cannot connect two computer together without the T-connectors
and termination either as this will create line loading problems the
same as not having terminations on the T.
good luck.

Subject: Firewall throughput?
Date: Mon, 11 Jan 1999 15:03:44 -0500
We are currently using a PC w/linux as our corporate firewall and the
question came
up about throughput.
How big a pipe can you connect to a PC before you have a problem?
How small a PC can you use for packet filtering? Application filtering?

Try mru 296 and maybe mtu 296. Refer to "man pppd" for more details.

Set the connection speed to the highest your serial port supports. For
example, if it's UART16550A, try setting speed to 115K.
Hope the above helps!

If you use a " - " between the "su" and "root", it will change the
environment to what would be expected if root had actually logged in.
So " su - root" would give you the root environment (i.e. PATH).

Check your error log, but I think the problem is: <Directory ~/public_html>
This means nothing to Apache. If you have a global "deny-all" on
<Directory />, this will prevent access to your home directories.
If all your user's home directories are under /home, I think you need
to have a <Directory /home> section that allows access.

One possibility is that some sites (especially banks) do a reverse name
lookup on the source address to find out the name of the machine
connecting to their server. If your IP address doesn't have a reverse
name record in dns, they reject the connection. Pings still work
(unless their firewall rejects them also).
To check this, you can use nslookup.
This example assumes the ip address of your machine is 192.168.1.1
nslookup # start nslookup
set type=any # tell nslookup to return info other than A records
1.1.168.192.in-addr.arpa # this is the ip address of your
# machine in reverse
If you don't get a valid reply, your ip address doesn't have a
reverse pointer, and may be causing your problem. You may have to
switch name servers to find the authoritative server for your address
range.

Subject: Q(nfs): sharing most of /tftpboot/$CLIENT/etc/ between clients
Date: 11 Jan 1999 21:24:30 GMT
A while ago I came across a patch of part of the NFS-system (don't
know whether client- or server-side) which allows the following:
Suppose a set of files (not dirs) on the server named e.g.
/anydir/theFile
/anydir/theFile%theHost1
/anydir/theFile%theHost2
Further suppose a mount on clients `theHost1', `theHost2' and
`otherHost' like:
mount -t nfs server:/anydir /anydir
The patch I am talking about makes sure that all three clients will
have a file named
/anydir/theFile
however the nfs-system maps one of the three files listed above
onto that name such that
`theHost1' in fact accesses server:/anydir/theFile%theHost1,
`theHost2' in fact accesses server:/anydir/theFile%theHost2,
while
`otherHost' accesses the default file server:/anydir/theFile
This mechanism is pretty nice to let serveral diskless clients share a
mostly common /etc, /lib or /bin directory on a server.
PLEASE: Don't tell me that I can get a similar behaviour with
softlinks. At least pam does not seem to like /etc/password to be a
softlink, and /etc/password is one of the few files the clients shall
not share.
Where is this patch?

Harald Kirsch

Subject: Routing with RedHat 5.2
Date: Mon, 11 Jan 1999 21:34:05 GMT
No matter what I try, I cannot get my machine to route packets
between the two ethernet interfaces. Hosts on both networks and other
networks can be pinged from my Linux machine. I have recompiled the
kernel for firewalling and have issued appropriate ipfwadm commands from
/sbin. I am not masquerading or proxying. My routing table appears to
accurately reflect the network configuration. I cannot ping the
ethernet "internet" card of my Linux machine from the "local" network.
I recently custom-installed RedHat 5.2. Here is what my test network,
basically, looks like;
^
|
_______|________
| eth0 |
| a.b.c.155 |gateway=a.b.c.254 (default)
|----------------|
| eth1 |
| 192.168.48.155 |
|________________|gateway=a.b.c.155

|0.0.0.0 |a.b.c.254|eth0 |

Any suggestions would be deeply appreciated. Thanks.

Subject: RH 5.2 & SMC 1211TX PCI Ethernet Card
Date: Mon, 11 Jan 1999 13:42:50 -0800
Hello:
Linux newbie here....installing a network is...interesting...
My problem: I'm using a SMC 1211TX Plug and Play PCI card and couldn't get
it to work with any of the SMC drivers available in the RH 5.2
installation. Any recommendations? From reading this news group I'm aware
that most cards support the NE2000 spec in some form or another but am
unaware of how to begin and the idea of recompiling the kernel is not too
appealing to a Linux newbie. (*Really New - I consider myself almost and
expert in NT and I feen I haven't even begun to harness the potential of
Linux.)
Thanks in advance.

Subject: tcp -ethernet
Date: Mon, 11 Jan 1999 16:29:29 -0500
hi -
I'm new to linux and am having a problem setting yp an ethernet
between my to machines. I'm running Linksys pci cards which work
fine in windows. I don't think it's a hardware problem.
I can ping localhost ok, but not the other machine
When I do a netstat, I have no tcp connections, only udp.
It also says "active internet connections (w/o servers)".
When I installed Red Hat 5.1 on both machines, I set it up for
tcp-ip networking. I believe that I have my 'route' and
'ifconfig' set right.
I checked /etc/hosts, /etc/networks, /etc/inetd.conf, and all
seem to be ok.
When I boot, it says that it finds my eth0 allright, though
lately one machine says it can't find the network name and then
wont start networking, then the loopback is absent from 'route'
and 'ifconfig'.
I must have something fundamentally wrong if I have no tcp
connections.
I tried configuring the files by hand and using 'netconfig' in X
windows.
Any help would be greatly appreciated.
Thanks,Chuck
