Subject: to make D-Link DFE 650 work on IBM ThinkPad 1411 under RedHat 5.1
Date: Tue, 09 Mar 1999 22:41:38 GMT
Hello all:
Could someone tell me how to make D-Link DFE 650 work under RedHat 5.1 ?
My laptop IBM Thinkpad 1411 with Pentium 300 4.3GB/32MB has both Window 98 and
RedHat 5.1 installed.
I have been following PCMCIA-HOWTO and other user groups. But I still can not
get network eth0 work.
Here is some system information might help you help me diagnosis my system:

Subject: Apache 1.3.4 'make install' problem
Date: Wed, 10 Mar 1999 08:06:35 -0600
When runnning make install for Apache 1.3.4, I get the error: "make:
'install' already up to date". I am running Red Hat 5.2 with kernel 2.2.2.
I have read the readme's to no avail. Here's the process I followed to
uncompress and compile Apache:
gunzip apache_1.3.4.tar.gz
tar xvf apache_1.3.4.tar
cd apache_1.3.4
./configure --prefix=/usr/local/apache
make
make install <-- Here's where it says "make:'install' already up to date"
Any suggestions?
Thanks,

This is completely out of date. Try
http://ostenfeld.dk/~jakob/Software-RAID.HOWTO/. This has been incorporated
into the latest raidtools, so you could simply go to
http://www.<country>.kernel.org/pub/linux/daemons/raid/alpha
and download the latest raidtools (raidtools-19990309-0.90.tar.gz) and patch
(raid0145-19990309-2.0.36.gz or raid0145-19990309-2.2.3.gz depending on your
kernel version). Remember, you will also need a pristine kernel source
package to apply the patch to.
>Here's a simplified step-by-step process

raidtools has been at 0.90 for a while. It is much improved on 0.5, so make
your life easy and upgrade. The changes to the init scripts which are in
RH5.2 to take account of v0.5 are junk, not just for 0.90 but for 0.5 as
well. If you have RH5.2, you will want to search the rc scripts for mentions
of raidstart and raidstop and remove the appropriate lines.

Not necessarily, it's just that inequal size partitions waste some of the
space on the larger partition.

What happened to mkraid? Without creating the device, you won't be able to
raidadd or raidstart it.
Also, this all assumes that raidtools was installed from an RPM. If he had
to download the raidtools tar.gz and patch, then he won't have known to
patch and compile a new kernel to include the latest RAID support (and
reboot so it's running), nor to compile the raidtools with "make; make
install; make install_dev" in the gunzipped/extracted raidtools directory.
The latter command can be very significant on a machine which has not had
RAID on it before. Without it, you can apply all the right commands and
still be told that the devices do not exist.

mkraid does this automatically for you now.

I assume linuxconf adds a line to /etc/fstab for the RAID array, does it?
This will only work if the RAID is already running, so you will want to use
RAID auto-recognition. Just use fdisk to mark any RAID partitions as type
"fd", and enable RAID auto-recognition when you compile the kernel. Now the
kernel will start any RAID arrays at boot time without any commands needing
to be issued, and shut them down cleanly when you shutdown. All you need to
do is add a line to your fstab (with linuxconf or whatever) showing where
you want the RAID array to be mounted, just like a normal partition.

Actually, it's all pretty easy now, thanks to some excellent work by Ingo
Molnar. Just follow the HOWTO at the URL at the top of the message, and
ignore all documentation in older raidtools packages.

Hi,
we've been trying to program a very basic client-server app (returns a
number++) using the RPCs but have met soooo many problems.
Here's the code, if anyone could be nice enough as to tell us what's
wrong with it.
On the 2 linux machines we've tried it we've had different results :
1. The server crashes (core dumped - segmentation fault)
2. The client can't encode the xdr_int
We're also looking for some code that would work so as to understand how
to use RPCs, the examples we've found on the net use <rpc/rusers.h>, and
it doesn't seem to compile on our machines...
Thanks a lot

Subject: Linux+Win95 networking problem
Date: Wed, 10 Mar 1999 10:55:15 -0600
Hi there,
I hope somebody just knows an answer to this.
I just set a two-machine network between a Linux and a Win95 (OSR 2) boxes.
They are connected with a crossover twisted-pair cable. The connection
seems to be working - I can ping each machine from the other one. I can
also ping the machines themselves.
Now here is the problem. On my Win95 machine I also have a couple of
dial-up accounts configured (one to my ISP and one to my work LAN). When I
try to do telnet or ftp from Win95 to Linux, I get a dial-up popup window
asking me to connect to my ISP account. When I cancel this, nothing
happens. It seems that neither telnet nor ftp can see the ethernet
connection.
Why is this happening and how can I fix it? I tried to remove the
"TCP/IP -> Dial-up adapter" from the Network applet, but this did not change
anything.
Additional info. I have a small Win98 partition on my Linux box and when I
boot it, my "network" works with no problems. I can see both machines in
the "network neigborhood" and I can mount local disk dirives and copy files
between them.
Any info will be appreciated. Thanks in advance,
Andy

Subject: routing tables - just being curious
Date: Wed, 10 Mar 1999 10:30:30 -0600
Hi there,
I have been struggling a little with my very small home network. I have
only two machines. The Linux box has a small Win98 partition (dual boot).
The other box is Win95 OSR2. They are both connected through a crossover
twisted-pair cable. The Linux box also has PPP configured.
The IP addresses of both machines are 192.168.48.1 and 192.168.48.2.
Now, without PPP running i get the following output from the "route -n"
command
Destination Gateway Genmask Flags Metric
Use Iface
192.168.48.1 0.0.0.0 255.255.255.255 UH 0
0 eth0
127.0.0.1 0.0.0.0 255.255.255.255 UH 0
0 lo
192.168.48.0 0.0.0.0 255.255.255.255 U 0
0 eth0
0.0.0.0 192.168.48.1 255.255.255.0 UG 0
0 eth0
My first question is: why is my local host 127.0.0.1 not 127.0.0.0. It has
been like this from the beginning (i.e. from original installation of
RH5,2). Does it matter?
The second question: how did the 192.168.48.0 line get into the routing
table and what iis it for?
As you can see I am just being curious and try to understand a little more.
When I fire up my PPP connection, the routing table changes to:
Destination Gateway Genmask Flags Metric
Use Iface
206.156.201.131 0.0.0.0 255.255.255.255 UH 0
0 ppp0
127.0.0.1 0.0.0.0 255.255.255.255 UH 0
0 lo
192.168.48.0 0.0.0.0 255.255.255.255 U 0
0 eth0
0.0.0.0 206.156.201.131 255.255.255.0 UG 0
0 ppp0
Everything seems to work fine, but in order for this to work I had to add
"route del default"
line to my ppp-up script just before the pppd line. Also, I had to add the
following line
route add -net default gw `hostname`
to my ppp-off script.
Is this correct? Unfortunately, for this to work for all users on my Linux
box, I had to make the route command suid.
Sorry for the longish ramblings. I would appreciate any comments.

Subject: Basic Samba configuration problem
Date: Wed, 10 Mar 1999 10:43:39 -0600
Hi there,
I have the smallest network of two machines: Win 95 OSR2 and Linux RH 5.2
with 2.2.2 kernel running together with all required updates (including
Samba 2.0.3). I have them connected using a crossover twisted-pair cable.
The machines see one another. I can ping from both machines.
I noticed that, after configuring the network card on my Linux box, my boot
process now stalls for a long time at two points. The sendmail daemon takes
about a minute to start, and the smbd takes even longer. Samba actually
seems to time out. Now, the smbd got configured to start from my original
RH5.2 installation, even though I did not have a network card then (I am not
sure why). Before I put the network card in my Linux box this did not cause
any problems.
Now I would like to actually try to use Samba. I looked at the
/etc/smb.conf file which got installed originally (I think) and tried to
check it with testparm Samba utility. It never gets beyond prining "loading
the configuration file" or something similar. I tried to make a very small
configuration file with just a few lines in it, but the testparm never seems
to do anything. It just sits there hanging even with an empty configuration
file.
I have a feeling that I am missing something very basic, but I cannot put my
finger on it. Any insight/help will be appreciated

Subject: NFS not supported by kernel ????? (Red Hat 5.2)
Date: Wed, 10 Mar 1999 17:24:05 GMT
Hey,
I used to run a very simple NFS network between
two RedHat machine (let's call them "mutt" and "jeff", ok?).
rpc.nfsd is started up at boot-time (default Red Hat intsllation)
and is running fine.
I use the following /etc/fstab on mutt:
/dev/sda1 /boot ext2 defaults 1 2
/dev/sda2 / ext2 defaults 1 1
...
(lignes deleted)
...
jeff:/v1 /v1 nfs rsize=4096,wsize=4096,hard,intr 0 0
and /etc/exports file on jeff:
/v1 mutt(rw,no_root_squash,link_relative)
And that work perfectly FINE for the last 2 months.
BUT,
yesterday I did nothing special to my system, except
maybe downloading and installing a shitload of .rpm on mutt
from the GNOME 1.0 distribution. And I also reboot
mutt twice to get rid of an ugly lpd color printer problem.
And NOW, from mutt I can no longer see jeff's files on /v1 via NFS!
Whenever I try to mount the NFS drive on mutt, at boot-time or by using:
mount -t nfs -o rsize=4096,wsize=4096,hard,intr jeff:/v1 /v1
I get the following error message:
"mount: fs type nfs not supported by kernel"
which of course I find hard to believe since I
used NFS everyday (or almost) for the last 2 months!
The funny thing is that jeff still sees two other drives
NFS mounted on mutt (jeff hasn't been rebooted in a while
and doesn't know anything about GNOME..)
Anybody has an idea as to what happened
to mutt & jeff ?????
Thanks!

Hello everybody,
I have setup RedHat Linux 5.2 on my PC. Now I want to reach the net from

I have a MDP7800-U Modem attached to COM3 in my WINNT.
When I reboot in Linux I changed to the /dev directory

Then using the control-panel I defined a PPP interface.
I typed in the phone number of my ISP, my userid and password. I use this

Sorry, NAT refers to an N to M mapping of IP addresses (and
possibly swapping port numbers). Masquerading refers to
N to 1 mapping. NAT is generic, Masquerading is specific.
