Reply-To: [EMAIL PROTECTED]
Hi there,
I'm a newbie with both Linux and Samba. I try to setup a connection
between
my Windows NT host named Liebling and my linux server named Interlux.
Following problem:
When I try to see directories on Interlux with the 'net view \\Interlux'
command
I get these error messages:
System error 53 has occurred.
The network path was not found.
Same command with the IP adress instead of the name works. Similar
things happen
from NT explorer. Mapping a Interlux share on a network drive with the
IP address
works but not with the name Interlux.
Surprisingly I can connect to Interlux (name!, not IP address) with
telnet or ping.
Settings I have already are:
- entries on NT in
Winnt\sytem32\drivers\etc\hosts, networks and lmhosts
TCP/IP protocol has Interlux as DNS server and WINS server
- configuration in smb.conf is:
[global]
workgroup = WORKGROUP
netbios name = INTERLUX
keepalive = 30
hosts allow = localhost, 192.168.1.0/255.255.255.0
browseable = yes
- Samba version is 2.0.3
I'm lost. Any help is highly appreciated.

The 0.89H tulip driver in both of the stable Linux releases (2.0.x and
2.2.x) is broken, but stable! The people who maintain the tulip
driver in the kernel think that "broken but stable" is vastly superior
to "works but track-record-unproven" and have steadfastly refuse to
put a working driver in the stable kernels. Their reasoning to me was
thus: "it may work for you but it doesn't work for Joe with the
No-Name tulip NIC."

Reply-To: "Georg Cantor" <[EMAIL PROTECTED]>
I have encountered a problem with Samba which is completely
incomprehensible.
There are 2 accounts which are always present was their passwords are added
to the smbpasswd file.
There are another 3 which never logon no matter how many times they are
added.
I have deleted and recreated the accounts on all 5, in both Unix using
useradd and userdel and in Samba by using cat /etc/passwd | mksmbpasswd.sh >
/etc/smbpasswd.
I delete the users by userdel, useradd them again, cat etc into smbpasswd
and then use smbpasswd username again.
The first two always logon, the other 3 never do.
It is as though Samba is using some unknown file which contains the
parameters for the first 2, and remains unaffected by my deletions and
readditions.
I normally get an invalid parameter error, a password error or password is
in correct or cannot logon to domain server or some other such answer.
Could something in my smb.conf file be the cause, or could the answer lie
elsewhere?
I have noticed some differences in the numbers found in the passwd, groups
and smbpasswd files, which refer to gids, uids, etc. Could that also be a
problem.
There is an article at
http://www.germanynet.de/teilnehmer/101/69082/samba.html#4.4
which mentions this uid problems.

Start by upgrading to dhcpcd-0.70 and make your entry in
rc.inet1 like this:
#! /bin/sh
#
# rc.inet1 This shell script boots up the base INET
system.
#
PATH=/bin:/sbin:/usr/bin:/usr/sbin
#
# Attach the loopback device.
#
ifconfig lo 127.0.0.1
route add -host 127.0.0.1 lo
#
# Initialize dynamic host
#
dhcpcd -h CR1008415-A
#
# Install the local network
#
ifconfig eth1 192.168.1.1 broadcast 192.168.1.255 netmask
255.255.255.0 up
route add -net 192.168.1.0 netmask 255.255.255.0 eth1
#
# The End
#
Of course place your own own subscriber name in place of
"CR1008415-A".
I use this box as a masquerade router to my local home
network, that is why there is a second ethernet adapter,
eth1 - just ignore if you just have a single computer
connected to your cable-modem.
That should work.

Brian

Make two mgetty.config files, eg, mgetty.config.day and
mgetty.config.night
Then configure the two files. For example in may .day file I have the
ringagain option, so that if I call in once, hang up wait 20 sec, and
then dial back in then mgetty will answer the modem and I can connect
during the day as well.
Ie this file has the two commands
rings 2
ringback on
in it (ie, if a call comes in, answer the next call, if it comes in in
the appropriate window, after 2 rings)
In the nightime file I have
rings 2
ringback off
Then In the cron file I have
0 18 * * 1,2,3,4,5 cd /etc/mgetty+sendfax;rm mgetty.config; ln -s mgetty.config.night
mgetty.config ;killall mgetty
0 8 * * 1,2,3,4,5 cd /etc/mgetty+sendfax;rm mgetty.config; ln -s mgetty.config.day
mgetty.config ;killall mgetty
Which switches the two config files at 8 and at 6PM, and kills mgetty to
(inittab will restart them with the new config files)
Note that you could equally well put in a rings 25 in the daytime one
and it will not answer until 25 rings have gone by (and any customer who
phones in and lets it ring for 25 rings deserves to get blasted with the
modem sound :-) )

Things look ok to me. Did you forget to enable forwarding?
Look in /etc/sysconfig/network .
FORWARD_IPV4=yes
You'll have to reboot to make this take effect. I don't recall how to
enable it via /proc/net/ip_forward.
I know by default forwarding is not enabled in RH5.2
