Subject: routing hell
Date: Tue, 11 May 1999 23:27:10 GMT
The linux box was working great for a while, but I think I changed something
and now it won't access the internet. When I try to ping my nameserver
(24.0.3.33) I get the message:
ping: sendto: Network is unreachable
I'm almost positive that the error is in the routing. I appended the outputs
of route, ifconf, and dmesg. I'm using cox@home with a static IP address.
Thanks,

You are a lifesaver! That is what the problem was! I never knew about this
setting and never needed to change it under Slackware. I also noticed when
it was booting up that I would see a message saying it was disabled.
I figured it was turned on later when I used the commands..

Subject: 3 X EthN Please help
Date: Tue, 11 May 1999 13:53:34 -0700
Ok here's the scenario. I have an Intel MB with an onboard intel ethernet
that I am not using and cannot be disabled. RH5.2 recognizes this ethernet
port. In addition, I have 2 PCI NE2000 compatible ehternet cards. I am
using one of them now and I need to set up the 2nd one (for a proxy later
on). RH5.2 also recognises both these PCI cards upon boot up (It recognised
the 2nd one when I appended lilo with 'append="ether=10,0xff80"). Now I
cannot get the 2nd PCI card to come up. ifconfig reports that eth0 (the
onboard ehter) and eth1 were up but not eth2. ifconfig eth2 up did not work
either. I farted around with liloconf and now I'm screwed everything up. I
have eth0,1 and 2 with only one of them up. Here is the output of my dmesg.
NET3.035ne.c: PCI BIOS reports NE 2000 clone at i/o 0xff80, irq

Now the PCI on Irq 11 used to be my original PCI card I accessed the
internet on. It looks like I'm accessing it on the PCI Irq 10 now. How do
I fix this mess and get both PCI cards to work and co-exist with the intel
onboard one (which cannot be disabled ... most unfortunately)
Thanks much

Your home directory has to be at least marked +x for all others the same
as your public_html directory underneath. I have something like this:
drwx--x--x bolek bolek bolek
drwxr-xr-x bolek bolek public_html
If your home directory is set to drwx------, it will fail. I've learned

Subject: programs hanging after sendto() call
From: [EMAIL PROTECTED] (J�rgen Skj�nes)
Date: 11 May 1999 20:57:52 +0200
(I hope this is the relevant group. Excuse me if it isn't.)
I have an old (RH 4.1 with upgrades) intel box running as a web server and
mail server, etc, and lately it is having problems when it comes to
things involving sockets (or so it seems). An ssh login onto the machine
takes a very long time to connect, the same with 'su', and a simple mailq
command may take several minutes.
A strace of mailq shows that it's hanging after a sendto call:
sendto(4, "86!\225\0\0\0\0\0\0\0\2\0\1\203\244"..., 136, 0, {sin_family=AF_INET,
sin_port=htons(871), sin_addr=inet_addr("XXX.XXX.XXX.XXX")}, 16) = 136
oldselect(256, [4], NULL, NULL, {5, 0}
(I've deleted the IP-adress, the XXX above is its own ip-number)
And here it hangs several seconds before it continues, but just to
end up hanging in the same place again later.
Does anyone know of any OS-limits it may have reached that could cause this?
I'm extremely curious about this and welcome any relevant feedback.
Thanks,

This is probably no specific help, but here goes anyway.
First, xdm doesn't broadcast. It responds to broadcasts. Your Exceed
does the broadcast, assuming its Xconfig is set to "XDMCP - Broadcast"
mode.
xdm on your Debian box will or won't respond to broadcasts depending
on its Xaccess file. On my system this is in /usr/lib/X11/xdm but
yours may differ. Check the file.
Of course broadcasts generally work only with a subnet.
Exceed doesn't always know the right broadcast address, so
you may have to configure it (under Transports, I think).
Have you tried setting Exceed to XDMCP Query mode going right to your
Debian box? Does that work? OK, next.
Exceed "XDMCP Broadcast" mode can be set to use a file listing
hosts to contact. Yes, they call it broadcast but it isn't. Are
you set to this mode? If so, maybe the Debian box isn't on the
list. Or maybe try this mode and put it in there. Does that work?
Hope some of this helps.

recompile the kernel with ip-masquarading. Then read all howtos. I know
that seem to be the stock answer but you will not know the questions to

I noticed that there is the following entry in this file:
May 2 22:22:57 teesmachine in.telnet[504]: connect from 12.220.47.110
I have a ppp connection to the internet and my question is did someone
from the above named ip address try to telnet into my computer ? Was he
successful ? How did he determine my ip address, since it is generated
randomly by my ip provider ?
I'm trying to learn about Linux, as you can probably tell.
Thanks for any responses !

Please try to use a more descriptive subject. It really helps us help you.
Your ISP may have switched to a different authentication scheme instead of
"ogin" "ssword" -- a site that uses PAP or CHAP exclusively would look like
that in the log, because it would dropping you directly into ppp and then
try to negotiate your identity in that stream of 'garbage'. But if your old
script still connects when you power-cycle the modem, that doesn't sound
like the whole story. Bottom line: rather than tearing apart your system,
have you asked THEM what THEY may have changed?
That part about the CD/TR lights staying on when the OH light went off is a
weird occurrence, all right!

a)Set up AutoPPP on mgetty. Use say chap authentication.
b)write a script based login for Win, where the script does the loggin
in and starting of ppp.
The first option is easier.

Doing this from out of inittab is plain silly. There is a specific

"man mgetty" would tell you about using a /etc/nologin.ttyS*
