Subject: Junkbuster Forwardfile Questions
Date: 25 Mar 1999 19:06:06 +0100
Got a question, think it's simple for Experts
On my Gateway-Machine sits the Named as forwarding nameserver, the clients
behind it use the Junkbuster filtering-proxy to browse the web.
The Forwardfile from Junkbuster points at last to the Provider-Proxy, but
so my Named is never used. What should i insert before the global-forward?
What to set in the forwardfile to get contact to the local Swat (Samba-Web
Administration-Tool) ? The following forwardfile dont solve that.
# Format:
# target forward_to via_gateway_typ gateway
# Enable the following entry to use the squid proxy installed on this
# system.
#* localhost:3128 . .
:443 . . .
:53 localhost:53 . .
# Forward fuer Samba Administration Tool
:901 localhost:901 . .
# Rest geht zum Proxy des Providers
* proxy.hanse-net.de:8080 . .

It isn't discussed because there's nothing to discuss. This is the
most basic mode of operation of pppd, everything else (dial-up,
dial-in etc) is an additional complication on top.
Just run pppd on the two machines:
pppd {port} {speed} {local-IP} noauth
You may have to delete /etc/ppp/options as some distrubutions put
silly defaults in there.
You don't actually need "noath" on current versions of pppd but may
need it in future versions so it's worth getting into the habit.
You may need the "local" option if your null-modem cable is not a full
null-modem cable.

One-way cable modem? <shrug>
Have you compiled a modular kernel and installed the masquerading
helper modules?
The one you're after is ip_masq_ftp.o and it should be in the
/lib/modules/(kernel-version)/ipv4 directory. Install it with either
modprobe or insmod and you should be off to the races.
There are other protocol helpers in there, too, such as Real Audio,
IRC, and Quake :-).

Subject: Dialing into Linux box
Date: 25 Mar 1999 23:12:03 GMT
To all,
I have RH5.2 and am trying to dial into the modem that I have connected to
it. I have added the necessary line to "inittab" to respawn mgetty for
each new call. I am able to dial the modem and get a handshake from it.
But, after attempting to negotiate the username and password, it
disconnects. I believe I have the proper permissions set for the username
that I am dialing in with. Any suggestions?

I've tried setting up the Apache server (suse seems to configured everything
ok).
I've started the httpd, and have no errors in the apache log.
i've not made any changes to the httpd.conf, the impression I get from
reading it, seems to be its all operational,
i think its setup to listen for http info, on all networks cards on port 80.
When I type the ip into my netscape brower though I get nothing, I should
get the apache docs.
I know I'm missing something obvious, but the faqs are not helping me.
Any ideas???

Hi,
I've gottwo machines that I want to set up as a mini nis domain. Setting
up the server went ok, but I can't seem to get the client on the other
machine working.
Both machines run RH 5.2 and I followed the HOWTO quite closely as this
is new territory to me.
anyway, after I everything is said and done I start ypbind
[root@thor /etc]# rc.d/init.d/ypbind start
Binding to the NIS domain... ypbind
# and then we test ...
[root@thor /etc]# ypcat passwd
YPBINDPROC_DOMAIN: Domain not bound
No such map passwd.byname. Reason: Can't bind to server which serves
this domain
according to the man page ypbind stores the binding information in
/var/yp/bindings/* _but there is nothing there_...
If I run ypbind manually I get
[root@thor /etc]# /sbin/ypbind --debug

Don't start with man pages; start with the Networking-Overview-HOWTO,
the NET-3-HOWTO and the Network Administrators Guide, which is part of

Hi,
Does the following conf. sounds familiar to you? I'm running my box with
routing and firewalling capabilities. For accounting puposes I setted up
some accouning rules with "ipfwadm -A" and analyses its output every minute.
This functions pretty well but now I provides my users the proxy SQUID. But
due to Squid I can't use this to track how much of the bandwith in a
certain time-period a client used.
I doesn't have a clue. What can I do to make Squid list this in a Log. How
to read the Output?
thanks for answers

Once the kernel has been compiled, save it somewhere next to the
existing kernel (for convenience). However, *don't* delete the old
one. My kernels are located in /boot/ as
vmlinuz-${version}-${release}. (If I compiled the kernel myself, the
release ended up something like 0.${compilation-number}, but that
doesn't matter.)
You'll also want to save System.map which should be in /usr/src/linux/
or whereever you put the source. I copy it, too, to /boot/ as
System.map-${version}-${release}.
>From there, I have symlinks. /boot/vmlinuz points to the kernel that
I want to be the default; vmlinuz-prev points to the last known good
kernel; System.map points to the System.map corresponding to the
default kernel.
>From here, I have /etc/lilo.conf look like this:
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
image=/boot/vmlinuz
label=linux
root=/dev/hda7
read-only
image=/boot/vmlinuz-prev
label=linux-prev
root=/dev/hda7
read-only
other=/dev/hda1
label=nt
table=/dev/hda
Pretty simple. I just changed the symlinks and rerun /sbin/lilo (as
root). That way, I don't have to modify lilo.conf every time I try a
new kernel. As long as the symlinks are kept up-to-date, I know that
I always have a working kernel in case the old one crapped out on me.
This is what the relevant files look like in /boot/:
lrwxrwxrwx 1 root root 20 Mar 22 22:28 System.map ->
System.map-2.2.4-0.1
-rw-r--r-- 1 root root 174516 Mar 22 22:28 System.map-2.2.3-0.4
-rw-r--r-- 1 root root 182795 Mar 24 13:40 System.map-2.2.4-0.1
-rw-r--r-- 1 root root 10759 Mar 22 22:40 kernel.cfg-2.2.3-0.4
-rw-r--r-- 1 root root 11545 Mar 24 13:40 kernel.cfg-2.2.4-0.1
lrwxrwxrwx 1 root root 17 Mar 24 13:39 vmlinuz -> vmlinuz-2.2.4-0.1
-rw-r--r-- 1 root root 509790 Mar 22 22:27 vmlinuz-2.2.3-0.4
-rw-r--r-- 1 root root 525648 Mar 24 13:39 vmlinuz-2.2.4-0.1
lrwxrwxrwx 1 root root 17 Mar 24 13:39 vmlinuz-prev ->
vmlinuz-2.2.3-0.4
Even when I compile a kernel of the same version, I always save it as
a different name here. For instance, the next time I compile a 2.2.4
(if I have to, that is), it'll be vmlinuz-2.2.4-0.2 so that I can keep
the 2.2.4-0.1 kernel around if I screw it up.
Redundancy is a good thing when you're talking about booting your
system. If you mess up the kernel and don't keep a good one around, I
*really* hope you have a boot-disk and/or a friend with a working
kernel for you.

I assume you mean IO address of 0x2a0, not DMA.
I would suggest setting up the card with a DOS utility that came
with it. Disable pnp, so it is stays the way you set it. My guess
is it is changing the interrupt level to something else.
Before you install the card you might want to take a look at
/proc/interrupts
and /proc/ioports.
You may need to add the 'append' statement to /etc/lilo.conf
Although with 2.0.35 and above this doesn't seem to be needed as often.

Subject: Dual NICs, only one rx/tmt
Date: Fri, 26 Mar 1999 12:51:29 GMT
After much reading of postings and HOWTOs, I have been able to configure my
linux machine (kernel 2.0.35, SuSE Linux 5.2) with 2 NICs (one Western
Digital, one 3com 3c509). Both cards are recognized in ifconfig. eth0 (the
WD) works fine if it's alone, but when eth1 is installed, only eth1 (3c509)
will receive or transmit packets. There does not appear to be a conflict
with IRQ or base address. How can I get both NICs functioning, so I can use
this machine as a firewall?
Thanks for any help you can give - I see that many others have had similar
problems.

It sounds like squid is simply running in foreground. Have you verified
that squid is working by try to use squi from another workstation? If
it is then put squid in background or put it in your rc.local script.

We did something similar. We're currently using RH5.2, I'm sure others
would do just as well.
We did find that when you use 2 ethernet cards it is best to usr 2 different
brands. It has to do with how linux recgonizes cards. The may work better
now that when we did it. We used a
3com509 and an ne2000 clone.
I personally don't like sendmail. We use qmail: www.qmail.org and it
works great, and it was quite simple to setup. There are some RPMs
available for it now too. However, you'll find more people that have used
sendmail. If you go with sendmail, make sure it is at least version 8.9 .
Basic web hosting is very simple with standard apache server that comes with
RH.
The firewall question is more complex. What do you currently use? Does it
need to
be a swapout for the NT system your using, with no changes to the clients?
Linux 2.0 has a built in simple NAT firewall which operates at the IP level,
call IP masquarading.
Linux kernel 2.2 has a more capable NAT firewall call IPCHANS. (rather new,
I've not used)
A SOCKS proxy server (with IP forwarding off, or you really don't have a
firewall), operates
at the trasport level. www.socks.nec.com We use SOCKS at work, but that
may not be best for you. I use IP MASQ for my home network.
If you can change the clients setups fairly easily, IP masqurading is the
simplest to setup.
I've never used DHCP.
Obvious advise: get things working in increments.

Please read the manual page to rpc.yppasswdd. For this reason, it was
written:
-e [chsh|chfn]
By default, rpc.yppasswdd will not allow users to
change the shell or GECOS field of their passwd
entry. Using the -e option, you can enable either
of these. Note that when enabling support for
ypchsh(1), you have to list all shells users are
allowed to select in /etc/shells.
