Subject: a few newbie problems
Date: Sat, 27 Mar 1999 14:01:37 GMT
ok....so ive just begun using linux as a way of getting away from the
horrible mess that is win95/98....but have a few problems.....first of
all, if there any database of linux drivers on the net? ive just got a
new ethernet card and have configured it so that from windows boot i
can access my uni's network....but no matter how i try i cannot do the
same thing for linux....i can't even get the drivers to install
properly. Im not sure that the drivers i were given were even
complete. it came with 4 files, 2 c scripts (space.c and rlt8029.c
(the card's brand is realtek)) a Makefile file and a config.in .....no
configure, and as the only way i know of installing stuff (save using
rpm) is ./configure, make, make install i am stuffed. I have tried
ignoring the fact that i don't have the drivers working in the hope
that somehow a default linux ethernet driver will kick in and
configured the card in netcfg.....but to no avail. i don't think there
is an entry for /dev/eth0 (which the card is) ive tried setting the
DNS and DHCP servers up as eth1 and eth2 in the hope that this would
help but it hasn't....as my knowledge of networking is very shaky i
haven't thought of anything else to try...if anyone can help me that
would be great...i can mail a copy of the drivers. Also, is there a
file manager similar to XTGold in linux? and one last thing....ive
been recommended X11amp, but after d'ling it ive run into the brick
wall of library dependancies....the program itself needs a recent
version of the gtk, which in turn requires an equally new version of
glib...after downloading both, and following all instructions i have
been able to install glib and get it fully functional, and install
gtk....but when i try to install X11amp it doesn't detect gtk....i had
problems attempting to get gtk to detect glib, but it did happen in
the end after much editing of ld.so.conf as advised in one of the
readme files. a similar file for gtk did mention environment variables
or something like that, but i have no idea what they are. if anyone
could plz help me with any of those problems, that would be great.
thanks in advance

If this helps any....
Im running redhat 5.2 and i just changed the permissions on the modem and
can bring up
the net connection thru xwin as any user. I think it goes as below but you
might want to look]
up the correct number (666).
chmod 666 /dev/modem
Didnt catch the particulars in your case but this works for me.

you can use one network card to alias for 2 or more ips in two or more

The smallest I've ever ran it on was a 386DX-25 with 4 meg of ram 100
meg HD. This was a special use machine and no one could be happy on it
for general use if they'd ever been on faster machines. A 486-66 with
16 Meg of ram is OK for most things. It's too slow to run the heavy X
suites like KDE or Gnome, but it's fine for X with fvwm or some other
light weight window manager. You might think about getting a very
small 486, like a 33 with 12 meg and no HD and use it strictly as a
firewall machine.

Subject: Re: Newbie struggling with Samba
Date: Sat, 27 Mar 1999 15:12:49 GMT
It could be a couple of things ... I'm not familiar with Redhat but have used
Samba extensively with Slackware, IRIX, and SunOS.
1. If you are using NT Service Pack 3, it doesn't automatically send plain
text passwords to clients and Samba my not be set up to handle encrypted
passwords. At the Samba website you can down load a registry entry
NT4_PlainPasswords.reg that will set NT not to encrypt plain text passwords.
2. Are you running smbd and nmbd as a service or as Daemos? If you are
running as a service (check /etc/inetd.conf) you may want to consider running
them as Daemons. This can be done by putting the path to your programs
(/usr/local/samba/bin/nmbd) in /etc/rc.d/rc.local. This solved a lot of
problems for me with Slackware 3.3 (Kernel 2.0.33)
3. Try another user name. As you may or may not be aware, Unix in general
does not automatically allow root to do certain things (ftp for example)
because of the security risks involved.
4. Change security in SMB.CONF to security=user. This will allow users on
the Linux computer to access shares based on securities set up in Linux.
5. Have you created smb shares in SMB.CONF?
I hope these help.

if ppp0 does not show up with ifconfig you have more than a routing problem.
The ppp interface is not active. after you dialed with minicom did you exit
without resetting and then run pppd?
for example:
run minicom
dial in and login
alt-q
exit without resetting
pppd /dev/modem 115200 defaultroute &
ppp0 should show up in ifconfig
trying pinging.. if the gateway is the only computer you can ping, then you
have a routing problem.
you can fix that with
route add default gw gw.ip.numb.er ppp0
hope this helps..
I have a question of my own.. i just installed linux SuSE 6.0 yesterday and i
am a linux newbie.... i've read EVERY thing i could find that is relevent at
LDP and the above is the only way i can get connected. during bootup, it
says that diald is active but! the modem never trys to dial out. i use YaST
to configure my ppp connection but again, diald doesnt dial.. ironic eh? so
i end up doing the minicom/pppd thing.. which is a pain...
any brave soul willing to help me tackle this? i'm a newbie but not totally
stupid so i promise i wont be too frustrating to help..
thanks
mike

This sounds like 10baseT with an RJ45 connector.
In that case there IS no RTS/CTS; it's just a matter of unidirectional
signals (differential pairs) each way.

A cat-5 crossover cable is available, all right, but you could also
use a hub. A 10-megabit hub is cheap if that's what you're running.
100-megabit hubs are more expensive and don't make sense for less
than four computers. For three, you might as well have four NICs
and point-to-point with the middle computer acting as a router.
(100 Mbit NICs are about $15 each, much less than a cheap hub.)

Allison,
I've done serial transfers from the CD on my Win 95 desktop to Linux on
my laptop. Minicom was part of the Slackware disk install. The
transfers allowed me to finish the setup. Check to see if you have a
comm. program. If not you'll have to look into NFS. I haven't setup
NFS yet so don't have a clue.

Date: Sat, 27 Mar 1999 17:07:41 +0200
Hello
I'm running RedHat 5.0 on an i586 machine, and experiencing some
problems while booting
after i have changed the hostname from "localhost" to "bingo".
the machine is connected to a LAN with three computers without any
connection outside.
all machines have the same problem. (of course, each has different name
and ip)
1. the problem: while booting the machine gives the message: "cannot
resolve hostname" and sendmail hangs for awhile.
2. i have changed the machine name by editing the /etc/sysconfig/network
file and setting the parameter HOSTNAME=bingo.
3. my /etc/hosts looks like that
127.0.0.1 localhost
192.0.0.1 bingo
192.0.0.2 baron
192.0.0.3 humi
4. my /etc/host.conf has:
order hosts
multi on
5. ifconfig and route are fine. i checked it with ping from one machine
to another and it works works fine, using IP's or names.
6. /etc/resolv.conf is empty
what's wrong??
I would appreciate if you will email you're answer to my email too,
since i might miss the answer on the group.

I would highly recommend setting up yoru linux box to accept encrypted

passwords. What you need to do is add a line in your smb.conf file
that says:
encrypt passwords = yes
That will switch Samba to encrypted password mode....also, modify the
line that says:
security = <whatever> to security = user
That shoudl fix that problem....then you can login to your Linux box
as whatever user you created.

I would appreciate assistance in getting my small network working. One local

I have RH 5.2 installed on one computer with eepro100 (eth1, 192.168.0.3) and
3c509 (eth0, 192.168.0.1) cards. I have Win95 installed on another computer
with nic (192.168.0.2) card. All cards are cabled to 10base-T 3 com Office
Connect hub. I can successfully ping all three addresses from Win95 machine
and all but 192.168.0.1 from RH machine. Packet lights flash on the hub only
when pinging between machines AND when trying to ping 192.168.0.1 from RH
machine.
RH nic drivers are loaded as modules.
(P.S. My earlier post apparently did not work. Pardon the repeat, if is shows

As far as I know RedHat 5.2..with the default installation has that
enabled. And I would much rather struggle through a kernel
recomplilation that start throwing out plain text passwords,
especially if your box will ever be connected to the net.
