What exactly do you mean by "sends a (UDP) GRE packet"? Is a UDP packet for
your office host going out the Internet interface rather than over the PPTP
channel? Check your routing tables to make sure that a route for your
office network points at the PPTP client, and on the PPTP client that it
points over the PPTP link.
A tcpdump log of this would be helpful.

Ummm...you didn't give much info so...
1. Make sure your kernel is set up for it. Read the IPMasq-Howto.
2. Make sure you use ipfwadm (kernel 2.0.*) or ipchains (2.2.*) to
set up your forwarding rules. Read the IPMasq-Howto.
3. Make sure your local net works w/o ip_masq. I.e., can your
gateway and masq'd machines talk to each other?
4. I think Redhat has some gay thing that disables ipforwarding
by default and so do the 2.2.* kernels. Try this:
"echo 1 > /proc/sys/net/ipv4/ip_forward"
5. I don't know, but I found it pretty easy.
That is all.

Subject: Linux RH5.2 USR 56k pnp modem Issue
Date: Tue, 16 Feb 1999 03:00:50 GMT
I initiate a dialup - the modem goes through the routine (i.e., it makes a
connection) but fails because of the following: not clean 8 bit serial
received; problem bit 7 is set to 0.
I do not believe I need to go into isapnptools since the OS recognizes the
modem; however, I cannot complete a connection.
Any thoughts?
Thanks

It means a name server is listed as being authoritative for a zone
(because the delegating zone has listed it in a NS record), but that
server is not actually authoritative for that zone. It basically means
someone (not you) has misconfigured their server.
See www.isc.org for the source code and documentation for named, in
which you can find a more detailed explanation if you desire. Or better
yet, get the O'Reilly book "DNS and Bind", by Cricket Liu.
You can probably turn this logging off with some magic in named.conf;
check the man page that comes with your system.
Or better yet, as someone else suggested here, turn off named entirely
and set your /etc/resolv.conf file to refer to the campus nameservers,
ns1 and ns2.berkeley.edu. You don't need to run your own version of
named; it opens up one more potential way in for crackers, and it can
use quite a bit of memory.
BTW, what version of named does RedHat 5.2 come with?

Date: Tue, 16 Feb 1999 03:30:50 GMT
Ok, I've lost too much hair trying to decipher this one, time to ask
for help.
I'm attempting to redirect certain ports to an NT machine behind a
Linux firewall. I want linux:8000 -> to nt:80, etc.
I've got the IP forwarding turned on and I'm masq'ing fine for the
whole network going to the rest of the world. Using redir nt 8000 80
works fine.
I've used ipmasqadm to set this up:
TCP linuxbox ntbox 8000 www 10 10
But a telnet linuxbox 8000 gives me a connection refused. A telnet
linuxbox 8000 when redir is running works fine. What am I missing?
I believe I have my kernel complied correctly:
CONFIG_IP_FIREWALL=y
# CONFIG_IP_FIREWALL_NETLINK is not set
CONFIG_IP_ALWAYS_DEFRAG=y
CONFIG_IP_TRANSPARENT_PROXY=y
CONFIG_IP_MASQUERADE=y
CONFIG_IP_MASQUERADE_ICMP=y
CONFIG_IP_MASQUERADE_MOD=y
CONFIG_IP_MASQUERADE_IPAUTOFW=m
CONFIG_IP_MASQUERADE_IPPORTFW=m

CONFIG_NET_IPGRE=m
CONFIG_NET_IPGRE_BROADCAST=y
# CONFIG_IP_MROUTE is not set

# CONFIG_ARPD is not set

Hi again:
I think the problem is with my bind. I am able to nslookup www.mydomain.com
which resolves to my IP address, but it should resolve to my IP address and
find my hostname and show up as www.mydomain.com in the aliases. I am not
able to nslookup mydomain.com? It says server failed.
any pointers??

IE is a terrible browser. it doesn't even browse. it doesn't even

that's right. and since i am using linux, the lack of internet
explorer means that microsoft doesn't even make a relevant browser.

Err, RTFM I guess. Found the site again and found out about

about the root mail. We forward root to the actual admins,
and it's useful. Is this inability for root to receive email
a QMail "feature," and can it be disabled? Thanks!

Reply-To: [EMAIL PROTECTED]
A newbie question. More to do with scripting than networks, perhaps.
I want to write a simple shell script that will log onto a ftp site,
upload a file, then log off.
It seems to be not possible in the bash shell, and ftp macros dont seem
to be the answer either.
The solution has to be very general. It has to work on Sun UNIX boxes too.
Any pointers in the right direction are welcome.
thanks

First off, let me start off by saying that you are a horse's ass. I've never
read such a snotty condescending post. I'm ashamed to be in the same
profession as you.
While the original poster was a bit simplistic, the fact is that web
building is about more than HTML. I personally am a systems admin, but
before I did that I used Visual Interdev 6 and SQL to create database
applications on the web. These applications worked in any browser 3.0+ and
through them I published and updated data through the web in ways that
require a deep working knowledge of HTML, Visual Basic, CSS, IIS4, SQL and
Windows NT. However, I've never been to validator.w3.org so by your esteemed
opinion I have no right producing web pages...
I just don't agree with your very vehement opinion. Web building takes all
types. I personally know HTML well enough and try not to do anything that
will break a browser. My reward is that I can focus on actually doing things
through the web. Some people focus on graphical appeal and produce beautiful
pages that may not conform to the somewhat fragmented "standard" but appeal
to their audience.
Web building is so much more exciting, fun, and powerful than your feable
pathetic definition will allow. I'm glad I see it differently than you do.

Subject: mgetty + ppp + pap = what user?
Date: 15 Feb 1999 22:45:31 -0500
Just a small problem:
I've installed mgetty to handle my ppp login using the AutoPPP feature.
Works great except users don't show up when I type 'w' or 'who'.
Redhat 5.2
Kernel 2.2.1
ppp 2.3.5
mgetty 1.1.14-5
This is my login.config entry:
/AutoPPP/ - - /usr/sbin/pppd auth -chap +pap login modem crtscts lock
I'm using a wildcard pap-secrets file so that users are authenticated
using my /etc/passwd file.
Everything is working like gold except the wtmp/utmp part. I thought
the double dash ( - - ) was supposed to handle that for me.
BTW, I've tried several ways, chap with a real chap-secrets, pap
with a real pap-secrets, the way noted above, etc..
All ways work, just no user entry (I think) in utmp/wtmp.
Also, I do get user entries when dialup users login using the "Bring
up Treminal Window after Dialing" feature of Winblows95/98.
What gives?
Thanks in advance. :^)
