Hi,
apologies for the cross post (I wasn't sure which newsgroup into which
I should post this). Is anyone using Linux and Pacbell's ADSL now?
I'm curious as to the performance. In addition, I know that Pacbell
doesn't support Linux. However, I'm thinking that it should be a
breeze since the communication is through a NIC card rather than a
specialized modem card.
Let me know.
Thanks in advance.

Hello,
I have PPP 2.2 setup on Red Hat 5 and have my modem working.
I can connect to one of my ISPs to the internet using PPP in Linux.
However, I cannot seem to configure PPP to connect to USWest.net.
If anyone has the ISP Uswest.net and can dialup to it in Linux, can you
please send me the chat script and the options you used?
USWest.net, of course, doesn't provide information on setting up a
connection in Linux, unlike my other ISP to which I can connect just fine.
Please reply to [EMAIL PROTECTED]

Subject: ppp numbering--control?
Date: 19 Jan 1999 02:55:49 GMT
Is there a way to control what my ppp connections are numbered? I
currently have 2 ppp connections--a dial-up isp connection and a serial
cable ppp connection. At this point, they're arbitrarily numbered based
on which pppd command is run first. I want to force the modem dial-ip
connection to be ppp0, and the serial connection to be ppp1. Is there a
way?

I guess I was just lucky. I picked up a USR/Megahertz combo card (33.6
modem + 10bt) and installation consisted of simply putting the card into the
slot and modifying my /etc/network file with the IP address that I wanted to
use. I havn't gotten around to setting up the Windows side yet but if it
needs even half of the disks that came with the card then it's definately
going to take longer than the Linux side did.

Pardon my ignorance, but when a crossover cable is used, isn't the
transmit of one connected to the receive of the other, and vice-versa?
Doesn't that mean that there is no contention (read collisions) between
the transmitters? Aren't there collisions with a hub because all the
transmitters are trying to share one medium?

Well I am somewhat stumped and need some direction.
I have two boxes, one running the SuSE 5.3
release and the other Slackware 3.4 or so.
I have them networked together using ethernet.
On the Slackware box I have an Eagle Travan-3 internal floppy tape drive.
All I want to be able to do is to tar some files to the tape drive from the
SuSe box to the tape on the Slackware box.
I have minimized security by putting in .rhosts and even hosts.equiv files
yet I still get permission denied messages.
I have the latest ftape module up and working and all other
network stuff runs great (NFS, rsh, etc.)
I have tried the commands tar -cvf hostname:/dev/qft0 filename and
tar -cvf user@hostname:/dev/qft0 filename.
Everyone has rw permissions on this device.
A pointer to a faq or how-to would be much appreciated.
Thanks

Subject: network speed question
Date: 19 Jan 1999 03:05:28 GMT
I recently got my two computers networked. One is a linux computer and the
other one is win98. After reading the NET-3-HOWTO I got the linux computer to
establish a network with the win98 computer by using
ifconfig eth0 11.0.0.2 netmask 255.0.0.0
route add -net 11.0.0.0 netmask 255.0.0.0 dev eth0
route add default gw 11.0.0.1 dev eth0
the linux box's ip is 11.0.0.2 and the win98 is 11.0.0.1
when I transfer files from the linux box to the win98 box via ftp the speed is
about 80KB/s. When the win98 sends files the transfer rate is about 500KB/s.
the same is true when I receive files from the win98 computer and upload with
the linux one.
The card is a 10BaseT RealTek 8029 PCI NE-2k compatible and I use and RJ-45
crossover cable to connect the computers.
Linux detects the card just fine.
The linux box is a pentium 100 and the win98 box is a relatively new pentium II
My question is, why does the linux box transfer files slower?, and is there a
way to make it go faster?
Is it because the computer is older (probably not since it also receives data
from the other computer fast), is it that Linux has a bad driver for it, is it
because my configuration is screwed up? or is it something else that I didnt
think of? All answers/comments are welcome. please be specific I am really new
at linux, I just got it installed 4 days ago.
Oh yeah, I have windows 98 on the Linux computer but I can't have my network
with windows since windows is being gay and not detecting my network card.

I set up a cacheing nameserver on my Debian box. I had actually pored
over the DNS-HOWTO but the debian package set up correctly "out of the
box". I also have Diald as well as IP Masq for my network. So when I
have a request for any kind of internet connection, the line goes up.
I have found that the cacheing nameserver provides a noticeable speed
improvement clicking through pages. Perhaps my ISP's nameserver is
slow. I'm glad I did it for the speed improvement alone, much less
the educational benefit.
If you do have IP-MASQ and therefere a network, you'll need to delve a
litter further into the HOWTO to set up name service properly for the
rest of your network. Frankly, on this small a scale it was
reasonably easy and worth the effort.

Yes it does. The very last page of the PPP-HOWTO is titled "Using PPP
across a null modem (direct serial) connection". I did it straight
out of that document and it was so simple you'll probably be
surprised.
Since it's so short, here's the page in question:
=================================================================
27. Using PPP across a null modem (direct serial) connection
This is very simple - there is no modem in the way so things are much
simpler.
First of all, choose one of the machines as a 'server', setting up a
getty on the serial port so you can test that you do have connectivity
using minicom to access the serial port on the 'client'.
Once you have this functioning, you can remove the getty UNLESS you
want to make sure that the connection is validated using user
name/password pairs as for a dial up connection. As you have 'physical
control' of both machines, I will presume that you do NOT want to do
this.
Now, on the server, remove the getty and make sure that you have the
serial ports on both machines configured correctly using 'setserial'.
All you need to do now is to start pppd on both systems. I will assume
that the connection uses /dev/ttyS34 on both machines. So, on both
machines execute the command:-
_________________________________________________________________
pppd -detach crtscts lock <local IP>:<remote IP> /dev/ttyS3 38400 &
_________________________________________________________________
This will bring up the link - but as yet you have no routing
specified. You can test the link by pinging to and fro to each
machine. If this works, bring down the link by killing one of the pppd
processes.
The routing you need will of course depend on exactly what you are
trying to do. Generally, one of the machines will be connected to an
Ethernet (and beyond) and so the routing required is exactly the same
as for a PPP server and client.
So on the Ethernet equipped machine, the pppd command would be
_________________________________________________________________
pppd -detach crtscts lock proxyarp <local IP>:<remote IP> /dev/ttyS3 38400 &
_________________________________________________________________
and on the other machine
_________________________________________________________________
pppd -detach crtscts lock defaultroute <local IP>:<remote IP> /dev/ttyS3 38400
&
_________________________________________________________________
If you are linking two networks (using a serial link!) or have more
complex routing requirements, you can use /etc/ppp/ip-up in exactly
the same way as mentioned earlier in this document.
=================================================================
Make sure the pppd lines are single commands of course. And make sure
you pick appropriate private IP's (ie 192.168.1.1 & 192.168.1.2).

Aaron, I'm also new around here, but can help a bit. The sendmail stuff in RH
5.2 should be started in /etc/rc.d/rc3.d/S80sendmail which really is a
symbolic link to /etc/rc.d/init.d/sendmail. To see if it's running on your
system, use the ps command, as in:
# ps ax | less
(pipe output to less so you can scroll up/down and see all processes.). You
should seea pid with something that says: "sendmail: accepting connections on
port 25". That will tell you that it is running. If it is not being started
at bootup, then I can't tell you much more, perhaps linuxconf will have
something burried in it to let you enable it at boot time.

try running /usr/bin/X11/Xconfigurator. It's prety easy and creates pretty
good X startup stuff. Also, you can use (in the same directory) XF86Setup,
which is an X11 based X setup utility that also works very nicely. The trick
is to get your card configured, and monitor as closely as possible in terms of
resolution, memory, etc. I found XF86Setup to be pretty useful in that it had
a pretty extensive database of video cards/monitor choices to pick from. If
you have a "supported" X11 video card, then it should be pretty easy. If not,
you may have problems.

I think perhaps if you get X configured correctly, the screen savers will

The only unwritten rule I've seen is to be polite when asking for help. There
have been a lot of buttholes who get frustrated with Linux, and then put in a
post with the header something like: "LINUX SUCKS", or whatever, to be
childish. Usually this irritates people to no end. I've found that most
legitimate requests for help get answered, so don't feel bad.

It's supposed to be all downloadable. D/l and install rpms should do it. You
have to scout around and find out what rpm's to download, find an FTP site, and
go get it all. Then you install the rpms. I'm not sure how they handle the
kernel upgrade, but it's not really hard to change kernels anyway, once they're
built. (Building them is not bad either, once you've done it a time or two).
Start with ftp.redhat.com, which is busy, so you'll be checking the mirror

Subject: network freeze when adding win95 laptop to Linux/Win95 network
Date: Tue, 19 Jan 1999 10:55:49 +0100
I have a problem: when I try to add my Win95 laptop to my Linux/Windows 95
LAN the network freezes!
Let me describe the situation:
'Old situation' - working fine:
===============================
I have a simple network with one Redhat 5.0 Linux server & one Windows 95
machine. The linux machine acts as a fileserver, running Samba, the Windos
59 machine (4.0.0.950B) is my regular 'workstation', with IPX/SPX, Netbeui
and TCP/IP installed. I use 10MB NIC's connected by a simple 5 port hub
(10MB). I can ping from/to both machines and access files, run a linux
webserver (apache, great!) etc. No problem at all, until....
'New situation' - not working :-(
==================================
I want to connect my laptop to the network. I use a 10/100MB Dynalink L100C
PCMCIA card (configured to run at 10MB). The laptop as also a Windows 95
machine (4.0.0.950B), same drivers etc. as the other windows95 machines,
except for the IP address of course. All IP addresses are static in the
192.168.42.xx range, netmask 255.255.255.0.
When the problems start:
========================
Now what's happening? Suppose I am running my network as usual: one Linux
server, one windows 95 machine. All working fine. I start pinging the
windows 95 machine from the Linux machine for a unlimited period to
demonstrate what's happening. Then I boot the Compaq 1220 laptop (connected
to the hub). The pinging between Linux and the workstation continues, but as
soon as the LINK led on the laptop's PCMCIA card flashes on, the pinging
from Linux to the workstation stops. If I try to ping form the workstation
to Linux I receive a 'Request timed out' message.
I now can not ping any machine from Linux, nor the Linux machine from any
windows 95 machine any more. However, I CAN ping between the two Windows 95
machines. If I then physically disconnect the STP cable connecting the
laptop to the hub, the pinging from Linux to the Windows95 workstation
continues as if nothing happened!
I don't know too much about networking, but I tried to examin the network
with Netstat. It does not report any hard errors.
PS: If I use the combination laptop + Linux only (without the 'windows95
workstation'), everything works fine too (so I think the laptop should be
configured properly). Also, the name to IP translation (via hosts file) is
ok.
This is a very nasty situation, since I lose contact with my fileserver as
soon as the laptop joins the network.
Can anybody help me (I hope I gave enough info)?

There a couple of ways to handle this:
* Synchronised workstations. In a situation where, say a dozen systems
mount a common /usr and have the same packages, the fact that the Deb/RH
packages will be overwriting one another is irrelevant. I do this with a
bunch of machines sharing /usr/share/texmf.
* Seperate /usr shares on a big system. Share /usr/local/systems/ws[1-9],
and mount each share on another system.
Of course, for the first case, one would ideally have a ``nousr'' version of
packages.

i've got problems while compiling a little IDS-tool called scanlogd,
which detects portscans.
if i compile it the following errors occur:
scanlogd.c: In function `process_packet':
scanlogd.c:216: structure has no member named `th_dport'
scanlogd.c:217: structure has no member named `th_flags'
scanlogd.c:250: `TH_ACK' undeclared (first use this function)
scanlogd.c:250: (Each undeclared identifier is reported only once
scanlogd.c:250: for each function it appears in.)
scanlogd.c:250: `TH_RST' undeclared (first use this function)
scanlogd.c:265: structure has no member named `th_sport'
scanlogd.c:344: structure has no member named `th_sport'
when i look in the files tcp.h and ip.h thera are, in fact, no
members like th_dport or th_flags.
maybe someone can help me fix that problem. the prog. is printed
in phrack53.
cu, and thanx in advance
mr

On my Debian system virtually all config files are in etc. As a matter of
fact, that is just about all that goes there. The last time I set up a RH
system it was about the same (a little more scattered but not that bad). Is
it just the name /etc that you don't like or ....?

Agreed. Perhaps I should have added that remote root logins are
prevented generally based on the EUID used, not the actual loginname
(at least, with standard security precautions activated). From that
point of view, this is a WU-FTPD flaw.

Yup.
