Hi all,
Here's a potentially stupid question for everyone that has a Linux box
as a gateway... do you leave it on all the time? Is there a Advanced
Power Management System equivalent for Linux?
I'm thinking of configuring a Linux box to act as a gateway and
firewall, but I don't like the idea of having to boot a second machine
up everytime I want to get on the net. Does that make sense?
Thanks,
Matt

I think the 2.2.x kernels have support for bandwidth control on an
interface. Using this you could specify a maximum bandwidth for an
interface. If your route was set up correctly it would ditstribute
load between the four squids evenly, with a maximum load on each. For
the details, grab the kernel source and read the docs.

I have a problem with a proxy server being syn flooded. From what I have
read, this hole has been fixed in all recent kernels.
The really strange thing is that I have SCSI errors coming up at the same
time as these syn-cookies messages come up. I think this is probably more
than coincidence. The disk doesn't even boot now.
If anyone has any ideas or suggestions please reply to me via email.

I have used Caldera OpenLinux Lite 1.1 and Red Hat 5.1, I cannot get
connected to my ISP on either, but on Caldera I couldn't get sound or my
joystick(for fly8) working. I can on Red Hat though. I am ordering Debian,
Slackware, and TurboLinux from CheapBytes though and plan to try them all.

Reply-To: [EMAIL PROTECTED]
Hello !
I have a problem getting pppd-2.3.5 to work. This prevents me from using
newer kernels,
I can connect to my ISP without problems, but afterwards I'm not able to
ping the remote gateway. However I can see Transmit- and Receive-Lights of
my Zyxel-ISDN-Modem flicker when doing a ping. The routing scheme is very
simple, because I don't have another Network-Adapter installed. My
ppp-options file is also very simple, defaultroute is enabled.
I'm using kernel 2.2.0, glibc 2.0.7 and net-tools 1.50.
Here's the output of some programs, I noticed that the transmitted packets
are ok, but ifconfig shows 6 received packets ok but the following packets
seem to have errors, see below:

I think Intel usually tests out best. DEC Tulip cards are very popular, and
a knock-off of them, since they have several functions that nothing else
has. Actually if you knew how to compile your kernel to support the Tulip,
say 2.2.0 kernel, read the docs, then there are some modes you could use
to get speed from the Tulip. Otherwise, just out of the box, Intel wins
published tests. I'm sure someone here has their own real-world tests,
though.

Unix doesn't have a route back to Win98's network. Does Unix have a
default route installed?

check your routing on the unix box.
win 98 knows the route to the unix network.
unix don't know the way back.
on the unix box :
route add net network-win98 router2 1

Oh knowledgeable sendmail gurus, I need some help!
First the problem. All mail is received and sent properly via UUCP,
however all incomming mail gets put right back into the uucp queue to be
sent back out rather than delivered to the local user. It is as if the
mail system is confused as to its idenity.
I think my sendmail problems might have to do with the strangeness of my
internet connection/mail domains. Let me just review it for you.
All email sent is eventually aliased to the andante.mn.org domain. This
domain is my internal domain on all my machines as well as the domain on
most of my mail. A local ISP provider Skypoint also hosts my visible
commercial domain andnate-systems.com. Mail sent to andante-systems.com
is aliased to andante.mn.org for all it's pseudo-users. For example
[EMAIL PROTECTED] and [EMAIL PROTECTED] are sent to
[EMAIL PROTECTED], [EMAIL PROTECTED] is sent to
[EMAIL PROTECTED], etc for all the pseudo-users in
andante-systems.com. I then pick up the andante.mn.org mail via UUCP.
I have a second provider for my ISDN internet connection. Gofast.net is
my ISDN provider. My internet connection is a Pipeline Router hooked to
the ISDN wall plug on one end and to my 3Com hub at the other. The
Pipeline Router acts as a router to the Gofast DNS.
My /etc/resolv.conf file looks like this:
############################
search andante.mn.org
nameserver 200.46.63.1
nameserver 209.46.63.6
The two nameservers are dns servers at Gofast.
Now Gofast does not appear to know about andante.mn.org. I can not ping
andante.mn.org. I think this might have something to do with my machine
NOT knowing its identity with respect to mail delivery. Does sendmail
as
the dns if the mail is local? I have tried putting the domain in the
sendmail cf file and it makes no difference. Should all that not be
retrieved from the above resolv.conf?
Please help if you can.
If anyone wants to see my sendmail.cf I can mail it.
Thanks

if you're still using the default stock kernel, then your boot options got
ignored because the network drivers aren't compiled into the kernel,
rather, they're compiled as modules. look in /etc/conf.modules to play
with the aliases and options.

poke around on metalab.unc.edu, there's serveral packages there designed to

See man ifconfig
ifconfig eth0 up 192.168.xx.xx
You'll need to add it to the routing table also, see man route
route add -net 192.168.1.0 eth0 for example.
You can do all this from netcfg on a Redhat system, easy and mouseable.
