Reply-To: [EMAIL PROTECTED]
i set up a dns on my linux box. it works internally and it works from
network connected clients. but i also want to use it for dial-in clients
via modem pppd.
the single line in the dial-in's .profile is:
exec /usr/sbin/pppd modem passive debug pppmaster:pppclient ms-dns
90.1.1.10
on the client-side i tried out both settings, get dns from server and
explicitely set it to 90.1.1.10
when connecting form nt4-cleint the messages log say:
Aug 16 08:59:43 support pppd[8021]: rcvd [IPCP ConfReq id=0x7 <addr
0.0.0.0> <ms-dns 0.0.0.0> <ms-dns 0.0.0.0>]

Aug 16 08:59:43 support pppd[8021]: remote IP address 90.1.1.48
which seems to be okay for me?!
ipconfig/all also states 90.1.1.10 as dns. but e.g. web-browser don't
find the site by name, only by 90.1.1.0.
"nslookup" on the client does not start with 90.1.1.10 as default. i
have to give the command
server 90.1.1.10
first, then it works. is this right, that i have to do that? standard
software (www-browser, ftp-clients) obviously don't use the right dns
and fail to connect on names (ip okay).
any idea? what did i forget? any answer please as well to my address

As far as I know, telnet is a BSD copywritten thing without public source
code. NetCat accomplishes the same tcp connection + telnet handshake as well
as other features and is open source, search for nc110.tgz. Also an encrypted
shell session client already exists, it's called ssh and is widely used.

Subject: setting up linux box as loghost
Date: 16 Aug 1999 07:24:16 GMT
I have Redhat 6.0 box setup behind an OpenBSD masq (along with a couple
of other comptuers). I also have a nameserver set up for the private
network, running on the masq. I want the linux box to be the loghost
for my fake domain. I have the /etc/syslog.conf file on the OpenBSD box
set up to log to a loghost and I have the nameserver setup with a CNAME
to the linux box as loghost.
The problem is that I'm not sure what I need to do on the linux box,
beyond running syslogd with -r, so that it will accept the log messages
from the masq. Do I need to add an entry to inetd.conf for the syslog
service? If so, is the line:
syslog dgram udp nowait root syslogd -r -m 0
and, if I do need to add an entry to inetd.conf, can i use tcpwrapper
with syslog. If I don't need to add anything to inetd.conf, what do I
need to do for a loghost?
Thanks

That card uses the ne2k-pci kernel module. I have 2 of them and they work
fine under linux. I have heard that Linksys has a linux support page on
their website now; you might want to check there, too.
And, not to be overly anal, but there is no such animal as linux 5.2.
There is a Redhat linux distribution that is at version 5.2. Redhat !=
linux. A distribution is just a collection of linux software and a linux
kernel and a nice installation program. Linux itself is currently at
version 2.2.11 stable and 2.3.12 (??) unstable.

Subject: DHCP AND WINS ISSUES. Here an answer I have found...
I posted a question earlier in the week,
I am able to issue IP, but my wintel box aren't able to login to NT Server.
=============
Everyone been telling me it a DNS problem, but it wasn't. I had to add to
more option lines to my dhcpd.conf file for WINS support.
You see all my wintel machine were getting IP and they were able to browse
the internet, but they weren't able to log in to the NT Server. The message
I was getting unable to find Domain to login to. So I try ping the NT box,
you could, but I could arp it.
So I sat down, print out the man page on dhcpd.conf and found that there are
options to add for WINS support. I try these two;
option ntp-servers
option netbios-name-servers
Some have say to just add the second line, but you need both. Wintel aren't
happy unless they see both.
Now my wintel boxes and happy cuz they can log in the network and surf the
internet, and they don't know that are using DHCP.
Thanks again.
Chuck

I have a problem in a similar vein:
I have PPP set up for root - with ppp-on being used to call pppd and chat,
etc and it works fine.
However, I want ppp to be available to a specific group of non-root users,
namely the group pppusers.
Accordingly, I have done the following:
made pppd suid root, and owned by group pppusers
Made the relevant users members of the pppusers group
When I call ppp-on (or even just /usr/sbin/pppd /dev/ttyS1) from one of
these users' accounts, I get a permission error on /dev/ttyS1. i.e. even
though pppd is running as root, the system will not let it access the
modem.
/dev/ttyS1 is owned by root and has tty as its group.
The only thing I can think of is that pppd is calling a shell script
somewhere and so the kernel is revoking its suid status perhaps.
I can understand this if I call pppd from ppp-on, but not when it's called
by itself. Any ideas?
(Of course, I could always change the group ownsership of ttyS1 to
pppusers but then I would be giving them direct access to the port)
(I'm running Mandrake 6.0.)
Thanks,
Richard.
