I'm having trouble compiling my kernel for the network card I want to
use (cCom 3c905b). I suspect part of the problem might be the version
of the gcc I'm using. I can't remember what version it is from when I
installed it. How can I find out and how can I upgrade it if need be?
Thanks,

Hi all
I thinking of trying out the new kernel.
(2.2.3)
How accurate is the current kernel
howto? The one I found on the Metalab
(sunsite) site is dated late May 1997.
Also has anyone run into problems
while trying to update?
Any input will be greatly appreciated

I'm using a K5-75 with two ISA ethernet cards as a Linux gateway. Downloads
on the other side are exactly the same speed as when the internal machine is
connected to the net directly.

For the last two years I have been trying to get my boss to allow the
use of Linux in a production environment. We have several SCO boxes
that share (thru NFS) a set of directories on an SCO server. When we
made our upgrade to the latest SCO (5.0.5a) we began having problems
with NFS. I saw the oppurtunity to introduce linux into my work
environment, and set up my dual Pentium Pro with SuSE 5.3 and kernel
2.0.35 to, to act as the new NFS server. However, problems arose when
the client SCO machines attempted to lock access to files on the Linux
server through lockd, and got no response from Linux. SCO's lockd works
through RPC and I can't find the Linux equivilant. Is there one? How
can I prove to people that Linux is ready for prime-time when it can't
even be used as an NFS server in a mixed environment? Any help would be
really appreciated.
Thanx

most cable modems have at most 2Mb or so bandwidth, so a 486 ISA machine
with any respectable NIC (ie, 3c509 or good NE2k card (not one of the $5
clones)) should handle it just fine.

I would try setting the media type via the 3com config diskette in DOS mode.
I know that doing it that way saves the setting to the cards EEPROM. I am
not sure how doing it under NT works, but it may just save it in a registry
setting. I have always solved all of my 905 problems from the DOS config
utility on the diskette (I have about 10 of these cards running under Linux

Yes, it would be interesting to see more on this in the free ORBs. We
built support for SOCKS-style gateways into our ILU ORB very
explicitly to use it from inside the Xerox firewall, but never
generalized it so that others could use it.

Try disabling the firewall and see if the other machines can access the
net. If they can then you have a firewall problem, if not then you have a
routing problem. This will open the firewall:
#! /bin/sh
/sbin/ipfwadm -I -f
/sbin/ipfwadm -F -f
/sbin/ipfwadm -O -f
/sbin/ipfwadm -I -a accept
/sbin/ipfwadm -F -a accept
/sbin/ipfwadm -O -a accept

There are two issues here; IP address asignment, and the firewall. You
can get by with only a few IP addresses by using DHCP or a proxy server.
You have to open a hole in the firewall for access to external services or
use a proxy server.

No, a kernel upgrade is not necessary. Your subnet mask may be part of
the problem but you have to eliminate other possibilities first.

Not a whole lot of people have success at this first off since Windoz
doesn't like to share (grin).
Most installations such as Redhat, Caldera all provide a way to resize your
hard drive partitions so you probably better read the installation
proceedures before actually trying it. These will be most likely on the
CDROM that your OS came on. If you bought a "boxed set", then check the
owners manual that came with it.
Just be sure you've backed up the important stuff before beginning. It is
entirely possible to destroy your Windoz partition and you'd have to
reinstall to get it all back.

Linux has both of these functionality built in but I question the reasoning
and use of a proxy server. Firewalling is fairly streightforward, even in
Redhat, and Caldera as they set up a faily stable basic firewall if you
install it during a fresh install. I don't use Proxy serving anymore since
it introduces problems for networking other non-standard things such as ICQ,
and video confrencing.

Date: Tue, 16 Mar 1999 22:42:54 GMT
I once downloaded and used a long (thorough) rc.firewall ruleset for
ipfwadm, which worked well on Caldera OpenLinux. But I needed DHCPcd, so had
to upgrade to RedHat, and went straight to kernel 2.2.3. I finally have the
networking up, but can't find a comparable ruleset for IPCHAINS (and lost my
old script, so I can't translate it with the wrapper).
The rc.firewall script ver. 1.5.1 from Freshmeat.net seems so small and
less DHCPcd friendly. Does anyone know where I can get a more powerful
script? It needn't support nfs, coda, XWindow ports, etc, just basic web and
e-mail services, very securely.

It sounds like either you have tcp_wrappers set up to deny telnet
connections, or inetd is trying to call a nonexistent telnet daemon.
I'll assume you're using Red Hat (the distribution I'm familiar with)
-- if you're using a different distro, some of these file names may be
different.
Check the file /etc/hosts.deny. Make sure it doesn't have a line like
"in.telnetd: ALL" or any other such thing (a line saying "ALL: ALL"
would also be bad -- that would mean you couldn't connect to this
machine in any way from anywhere!).
For more info on tcp_wrappers, "man hosts.deny" and/or "man
hosts.allow".
If that's okay (including if hosts.deny has nothing but comment lines
in it), then check /etc/inetd.conf. Search for "telnet" and you should
find a line like the following:
telnet stream tcp nowait root /usr/sbin/tcpd in.telnetd
Make sure that both /usr/sbin/tcpd and /usr/sbin/in.telnetd exist. If
either of them doesn't, you should be able to get them in RPM packages
off of any of Red Hat's mirror sites. Unfortunately, I don't recall
which packages you'll need for those, but a little hunting around
should turn them up.
If neither of those is the problem, try to telnet to the machine while
doing a "tail -f /var/log/messages" (or /var/log/syslog) and see what
entries pop up there.
