Use "ifconfig" and "route". Something like:
ifconfig eth0 down
ifconfig eth0 <new ip> netmask <new netmask> broadcast <new bcast> up
Then set the local net and the default gateway with "route".
If you included the output of "ifconfig" and "route -n", we could
comment on what was wrong with your attempts.

The drivers must be either compiled in the kernel or available as
modules. If you are using the stock kernel, it is probably the
latter. Do "lsmod" to see what modules are loaded, you may remove
unwanted ones with "rmmod" and load new with "insmod". To have this
done automatically, you may have to edit /etc/modules. Read
"man modprobe" first.

Curious ...
I'm having exactly the same problem. Its IP addresses, not a DNS thing.
Should I be adding a route to the ip-up file, when I'm using proxyarp?
My understanding of the doc's says that it should be working fine. What
have I missed?

This is not allways a good idea; sometimes the factory defaults are
perfectly useless.
It is better to set the modem to something which makes sense, save the
settings with at&w and then use atz as your init string.

Subject: 'xmit on stopped card' problem
Date: Fri, 02 Jul 1999 12:11:50 -0400
I have been getting 'xmit on stopped card' messages during boot
up with my main Linux server (TX-PRO II motherboard, NE2000 clone
or 3COM Etherlink-II ISA network card, Linux kernel 2.0.36) along
with serious problems ifconfig'ing the network interface. I found
a few messages on deja-news concerning similar problems and a
section of the netatalk page as well.
The news messages said that changing the IRQ and I/O ports of the
NE2000 card fixed a conflict with some built-in hardware on the
TX-PRO II motherboard, but I couldn't duplicate the fix. Even when
I replaced the NE2000 card with an old Etherlink-II card I still
got 'xmit on stopped card' errors during boot and I completely
lost the abiltiy to ifconfig the interface.
When I booted with the NE2000 it would be recognized early in the
boot process, right after the hard drive partitions, with the
correct I/O port and IRQ, but later (right around the time the
system goes multi-user) the boot process would complain about
the IRQ being used by an unknown device.
The info on the netatalk page, while it may apply to me, didn't
have any answers.
Does anyone know what is going on here. I'm getting pretty
frustrated with the whole mess. If I can't clear the problem
up I'm going to buy a new system and sacrifice the TX-PRO II
and Co. to the nether-gods in Redmond. (I've needed an excuse
to set up a game box)

If diald is starting pppd it must *think* your connect script
has succeeded but are you sure it has actually done the right
thing and got to the point of being ready for PPP? How do you
know that the modem flashing is LCP? Have you got debug on
for pppd? Does it see anything? Does it reply?

Ok, I finally was able to connect via ppp after many hours of fiddling
to get things to work right. (Hoo-ray). Now the problem is that ifdown
ppp0 will not work at all. I have to killall pppd.
The other problem is that ordinary users (Mom & Dad) can't kill the
connection. They are both members of the group pppusers. The error says
that they don't own the process or something like that.
pppd is setuid root.
I'm using Rh5.2 with that damn Linuxconf.
Any help would be appreciated.

Your net mask should be 255.255.255.0 if you are using a class c network
which I am fairly sure you are.
Using a net mask of 255.255.255.248 will have the effect of only the current
machine having access to the web.

I've got a similar problem with SuSE 6.0. However, I can surf because I
have squid and a caching nameserver set up on the linux box and my
internal machine uses those for web access. I can't ftp, use news or ping
out to the net though.
Could this be a problem with SuSe 6.x ? My setup worked fine under 5.3. I
needed to upgrade though for some other software I wanted to run.
Cheers, Sean.

you might have to add 'root_sqash' or 'no_root_sqash', not sure which.

Subject: Writing to a FAT32 partition from a remote machine
Date: Fri, 9 Jul 1999 19:08:00 -0700
I recently installed Red Hat 6.0 on one of our computer on a peer to peer
network to act as file server. Mounting the FAT32 local drive was
successful. Reading and writing using the local machine was successful too.
My problem is I can not write on the particular FAT32 partition when I used
a remote machine, I can read from it though.
I tried changing permission for the mounted FAT32 partition but it has no
effect. When i open the permission windows after making adjustments it is
always the old configuration, as if I did not changed anything (even though
I am logged in as root).
I do not have any problem reading or writing to linux partitions using
remote machines.
Sure hope somebody could help me out. Thanks in advance!

Date: Fri, 09 Jul 1999 13:06:10 +0200
You're right: I only think that the flashing lights on the modem are LCP
packets.
But on the other hand I use the normal script (ppp-on-dialer for RH 4.1) and
this works fine,
I get everything as it should be (name server, firewall etc). The only thing
I did was to tell diald to start this script in ppp mode. I think that should
be ok and working, or am I wrong? :-(
I tried to do debugging on pppd, but it tells nothing in the
/var/log/messages (syslog.conf changed,
syslogd restarted, options file debug; should be ok, or not?). It seems that
somehow pppd gets not the
the packages it needs to get to build a communication. The last thing the
kernel tells me in the syslog file is,
that the ppp line discipline is registered, there is no line telling that
pppd built a ppp device and when I
look via ifconfig there is really no ppp device. pppd is also *not* in
passive mode, not give a device and
all the other things that are mentioned in the diald man pages etc.
BTW, where can I activate the dial on demand option of the pppd and which is
the first version of
pppd that suppurts this feature (I'm having ppp-2.2.0f-2 installed)
If you have a working dail in script, please be so kind to mail it to me, so
that i get an idea where to look at
and where the problem might be.
Thnaks for your help

One possibility is to have a .forward file in your home of your linux box,
the other (more complicated)
possibility is, to have your sendmail rules (either sendmail.cf or .cw file,
I'm not at my linux box at the moment) rewritten, so that it forwards you

Subject: Re: Is subnetting = ip masquerading?
Date: Fri, 09 Jul 1999 13:30:32 +0200
NO,
ip-subnetting meens to splitt on big ip-subnet into several little subnets. The
use for this is for example, when
you have a company and lets say three different departments that should not be
able communicate whith each other you give each a different subnet mask.
ip-masquerading is if you have for example a linux host acting as a dial-up
server for the internet and a network also connected to this linux host, you can
'hide' the network behind the ip-address of the linux host, but access the
internet with your whole network. masquerading is the older one of the two things
masquerading and NAT (network address translation)
Hope to have something solved

Hi,
------ 192.168.1.222 192.168.1.193-------------192.168.1.194
|router|----------------------------|linuxfirewall|------------Internal
------ -------------
Now I have a network setup, and want them to go to the Internet.
I configured a Linux firewall gateway as a security door, but
I'm confused with the setup of routing table above.
The situation is:
The ISP gave me 32 IPs of which the netmask is 255.255.255.224,
(I just replaced the first 3 dot numbers as 192.168.1 as I
dun show the real IP here.) as drawn above, what can be the possible
routing table on the firewall? Of coz the default gateway of all
internal machines should point to 192.168.1.194. But I can't get
IP forwarding/routing working on that firewall. I am concern that
the broadcast IP 192.168.1.192 from the router cannot pass through
the firewall and thus making the internal network invisible.
Could anyone point out what's wrong? And how to archieve my original goal?
Thx in advance.

Subject: Problem with NIS
Date: Fri, 09 Jul 1999 08:20:27 -0400
Hi;
I seem to be having a little problem with NIS on a couple Debian 2.0r3
boxes.
On both the machines the following versions are installed..
ypserv-1.3.6
yp-tools-2.3
ypbind-mt-1.5
The problem is when we first setup the slave, the master was pushing out
the maps
to it just fine. After about 3 or 4 days (transfers once an hour) ypxfr
on the slave
starts complaining about "Master's version not newer" on passwd.byname.
The thing is
that the map IS in fact newer. A couple days later, it complains about
the same thing
about a different map. I assume that somehow the time stamp in the map
is getting corrupt.
The only way we can fix this is by doing a ypxfr -f on the slave, and
everything is ok for
a couple days. Can anyone help me out with this or point me into the
right direction on how
to fix it?
Thanks
