Subject: Setting up a news server
Date: Wed, 13 Jan 1999 15:25:30 GMT
Hello. I have a redhat 5.2 linux box, and I want to set up a news server.
Where could I get throughout information about it? I'd like to know what
server I should use (INN or CNEWS) and also where can I get a feed. I'm
planning to start with just a few groups for testing purposes, and then add
most of the news groups available. I have no hardware limitations, my line is
not that fast tough.
Thanx

The Microdyne NE2500s are PCnet boards. Best bet is to use the DOS utility
to configure them as non-P&P at one of the four ports that are probed by the
lance/PCnet driver, ie., 0x300, 0x320, 0x340 or 0x360. You can pick whatever
is available in your system for the IRQ and DMA since they'll get detected
by the probe. I have heard that they don't work when you try to install the
driver as a module so you might have to compile support in the kernel. The
install disk has the driver in the kernel so this last part may not be
necessary if you use the installation kernel.

Yes the command in deed does set it to have root privileges. But it
still will not execute for a user. Here is the command I use in my perl
script which calls the pppd command.
$command="/usr/sbin/pppd name \"".$NAME."\"".
" -d connect \'/usr/sbin/chat -t 45 -v ABORT BUSY \"\" ATDT".
$PHONE." CONNECT \"\"\' ".$MODEM.
" 115200 noipdefault modem defaultroute crtscts";
As you can see I pass pppd the name option here. The error message I get
is
FranksPC frank ~> ppp-on
/usr/sbin/pppd: using the name option requires root privilege
If I look at the file with a ls -l I get the following output
FranksPC root /home/frank> ls -l /usr/sbin/pppd
-rwsr-sr-x 1 root root 106876 Jun 8 1998 /usr/sbin/pppd*
Showing in fact that it is indeed setuid root.
If it is setuid root how come a user cannot execute the command? Am I
missing something silly here? I have tried every possible combination of
permissions but no luck only root can execute the script.
Thanx in advance.....

If you are running Slackware then run pppsetup
It will ask various questions.
You will need
the domain name of your ISP
your login name for the ISP
your password for the ISP
your ISP's DNS (Domain Name Server ) IP Address
your phone number for the ISP ( note well to read the questions fully eg
at this question your answer will be ATDT123456 not just 123456 )
unless you have a special setup you answer no to call back
My version screws up if you put in any initiaisation string just press
Enter on this. If you want to know how to correct it email me. I might
edit the source and re-compile some day.
When it has finished
run ppp-go
do tail -f /var/log/messages if you want but it will come back with a
local and remote IP address eventually
If it fails at this point make sure you have no default route already
set.
do
route del default
if you have.

Good that you have no hardware limitation. I handle a small part of
what's available, about 26k groups, and I handle about 11GB/day, keeping
my article size small.
I would use INN, Cnews probably won't keep up with "most of the news
groups available" any more. Diablo is nice, also.

Another stabe option is to setup sendpage on your Linux box. This was a great
free solution for solving paging problems that I once had.

Subject: ISDN and PPP over HDLC
Date: 13 Jan 1999 16:18:04 GMT
Reply-To: [EMAIL PROTECTED]
Hello all,
I have an Lasat unique 1280i external ISDN modem which has a RS232
interface. It works fine under Windows, but I can't make it work on Linux.
I am using the same init string as the windows software. It is
AT&FE0V1&C1&D2S95=47S0=0\P1&B2\C1&K3 which puts the modem in PPP over
HDLC mode (rfc1662). PPP negotiation goes well and ppp interface goes
up. But the IP packet does not go through this connection. Actually
what happens is that PPP frames are not received correctly from the kernel.
I tried a lot of ACYNCMAP and ESCAPE option combinations (and the most
wide used asyncmap a0000, escape FF) but it still does not work.
I have also PPP packets from the Windows software printed. The windows
software starts with LCP ConfReq asyncmap 0xa0000, pcomp, accomp, callback
0x600. The peer at the other side is a cisco router.
Thank you for any help or ideas.
Alex

I can't answer that. I seriously doubt that it's a problem with the
router. I'd almost bet money on it! By all means, try the udprelay and
I hope it works! Maybe this has something to do with the fact that
you're using a modem and udprelay would help that out. Like I said,
I've never masqued with a modem before so I know nothing about that.
If you have the HDD space, or an extra HDD laying around (heh, don't we
all??), try installing Linux on the Windows computer, establishing your
ISP connection, and then playing Quake from there, if your box is
inaccessible.
At any rate, good luck and I hope udprelay solves your problem!

Subject: tcp wrappers
Date: Wed, 13 Jan 1999 15:36:40 GMT
I've just tried to set up tcp wrappers on my server and have come
across a problem I can't work out.
Following the examples given in the default hosts.deny and .allow
files that came with the RH5.1 install I added the following;
hosts.deny
portmap: ALL <-- this was already in the file
ALL: 0.0.0.0/0.0.0.0 <-- added by me
hosts.allow
portmap: 194.129.122.0/255.255.255.192 <- this was already in the file
in.telnetd: 194.129.122.0/255.255.255.192 <-- added by me
in.ftpd: 194.129.122.0/255.255.255.192 <-- added by me
The problem is that when I do this I can't use ftp or telnet even
though the address of my PC is definitely in the network supplied. I
can only get it to work if I make the IP addresses 0.0.0.0/0.0.0.0.
Does anyone have any pointers as to where I've gone wrong?
TIA,
