Subject: Netscape - IP masquerade - WinNT
Date: Mon, 12 Jul 1999 01:19:32 -0400
Hi,
I'm running RedHat 5.2 on a linux server connected directly to a cable
modem with NIC #1. To a hub are connected the linux machine's second
network card and a WinNT machine, with more to come. I can get Netscape
connected to the internet on the linux box, but not the WinNT box; it
just keeps looking for an address. From WinNT I can ping to both cards
in the linux machine as well as pinging and tracert to the internet
successfully, using both outside ip addresses and URL addresses.
I'm running the following ip masquerade commands on the linux box:
IPFWADM -F -f
IPFWADM -F -p accept
IPFWADM -F -a m -S 192.168.0.1/24 -D 0/0 -P all -W eth1
Anybody know how I can get Netscape to work on the WinNT machine?
Thanks.
Vincent

I am planning to change from ISDN to ADSL in the near future, and need
some advise. I have 3 (currently) pc's on a home network, all dual boot
winblows/Linux 5.2. Should I reinstall Linux 5.2 using the Server
install option (on one of the pc's) and install a second nic for the dsl
modem to connect to (on the server pc)? As you can see I am a bit
confused about dsl.

I don;t have the solution but share the problem. I followed the same
steps as you, but for kernel 2.2.5. All of the modules that I
selected in makeconfig are loaded, and everything that I intended to
accomplish w/ the re-compile works. All of the modules that cannot be

Hi, David,
try "nbplkup". If the machine says "nbp_lookup: Invalid argument", then
there is no kernel-support for appletalk. In that case, try
modprobe appletalk
modprobe atp
If the modules are not found, then You should recompile the kernel, You
might compile appletalk support as a module. Then read the appropriate
manpages in order to configure properly. "man atalkd" is a very good
point to start reading.
Hope that helped

You can log in as a user and then issue the command "su -" to gain
root access.
A better way might be to use SSH. SSH will allow root access in a somewhat
secure way. One added bonus is that your transactions will be encrypted
so that no one can eavsedrop at you and pick up your password. If you use
telnet someone can, with a sniffer, get your password for the user account
and also root by looking at what you send in respons to "su -"... Telnet
also seem to be a fun toy to use by people cracking into systems (and people
seem to love to break into Web-servers nowadays...) I have disabled telnet
totally on my machines and only run SSH.
SSH can be found at ftp://ftp.replay.com/, RedHat rpm:s can be found in
/pub/replay/linux/redhat/i386
You can also look at http://www.replay.com/redhat/ for more info on
how to secure RedHat Linux.
To gain some root-access, i.e. use some programs that only root can
use, you can use sudo. But this is something I never tried so I can not
give you any more informtion about that.
Hope this helped!

Date: Mon, 12 Jul 1999 02:14:28 -0400
I've been running RedHat 5.2 for a few months now, and just tried to
reconfigure
my kernal to use IP Masquerading. I have Butzen and Hilton's book "The
Linux
Network" (which of course is for Slackware not RH) and went through the
kernel reconfig they recommend to turn on the IP Firewall / Masquerading
services.
The make procedures went well, I installed my new kernel and tested it,
but
when I go to try any of the ipfwadm commands, I get the message
"bash: ipfwadm: command not found"
It also complains about ip_forward, ipchains, and similar commands that
all the HOWTO's seem to expect I already have available.
Anybody got a hint for me? Do I gotta upgrade to RH6?
Thanks,

Hi everyone,
I was wandering if anyone has any suggestions regarding the following
diald behavior:
- diald brings up the link when it first starts up, without any
apparent requests.
- If I startup Netscape, diald brings the link up, but, Netscape never
gets the address resolved. If I stop the request and re-try, everyhing
is ok. Now this can get annoying and I end up forcing the link up via
ctrld.
Any suggestions regarding, especially the second problem would be
greatlly appreciated.

Subject: TCP packets
Date: Mon, 12 Jul 1999 00:17:45 -0700
Hi,
I am intending to write a proxy/logging user-space firewall that exploits
the '-r' redirect option of ipchains to send specific packets to a
user-socket so that they can be logged and examined in more detail. To do
this I would like to manipulate data coming from the socket
packet-by-packet (rather than the normal stream used by most
applications). I've examined opening the socket as a SOCK_RAW or a
SOCK_PACKET but both seem to be oriented towards different uses (RAW can't
even use TCP packets, and PACKET requires that an entire interface and
all packets to it be grabbed). I would also like to then forge packets
that have already been examined and retransmit them on one end of the
firewall to make them look like they originated on the other end (rather
then from the firewall itself). Treating everything on a packet by packet
basis allows me to ignore the abstraction of a TCP session and avoids many
other possible compications (as long as I faithfully reconstruct the
packet on the other end of the firewall once having examined it). Does
anyone have any idea how a socket can be read packet by packet in user
space? Any ideas vis-a-vis my packet re-writting idea (I've already
considered looking at IP spoofing code, I just havn't done it yet).
Thanks,
Sheer El-Showk

Have you checked what IRQ / Base Address the system thinks the card is
using? I think those 3com 509B usually come with firmware settings of IRQ=10
and BaseIO=0x300. Obviously the kernel has to agree with the card's firmware
settings and also those settings musn't conflict with other stuff. Most 3com
cards give you a DOS facility for changing firmware settings although it
sounds like you've already found that if the PnP is definitely turned off.
Also, what IP address are you trying to assign to the eth1? I think it must
be a separate IP network from eth0 as in AIX.
Hope this helps

Hi Marco
Just had some Beachvolley-Event (with very bad swiss weather and no
beach) over the weekend so I couldn't answer earlier. So here is some
very short explanation to make your 'wish' real.
So first off: Go to the link Bryan suggested and get all neccessary
files, like:
*ucd...snmp...3.6.2.tar.gz
*the first html-page with all linkz
*x-ucd-snmpd-tar.gz
(ft://ucd-snmp.ucdavis.edu/contrib/x-ucd-snmp.tar.gz) or
http://www.mhinc.com/tcl/ftparchive/sorted/net/scotty-2.1.5/scotty-2.1.5.tar.gz
but not HP-OpenView, coz it's not free and it is the hell. Just try to
find some specific IPACCT-Rules and you end up with a mess. Then
try once to configure HP-Openview to your exact needings:
There are just to much buttons. You can't involve your own
MIB-Modules or I couldn't involve the Modules and and and ... but
sure, you can take HPOV. Scotty works best for me and x-ucd..
I don't know yet, have to try out.
*Link: http://www.csc.liv.ac.uk/~daves/Misc/UCD/guide.html (to write
your own MIB-Modules.
After compile and install all. (You don't need to configure snmpd.conf
for a first walk) Then you should start the snmpd daemon and off you go.
Try:
snmpwalk -R public YOUR_DEST_IP
And there should be quite a big list scrolling down, depending on which
MIB-DB you install. Now changing a setting is pretty easy. Just hammer:
snmpset YOUR_DEST_IP MIB_ENTRY TYPE VALUE
YOUR_DEST_IP=IP of node you want to change an MIB-Entry
TYPE=The type is a single character, one of:
i INTEGER
s STRING
x HEX STRING
d DECIMAL STRING
n NULLOBJ
o OBJID
t TIMETICKS
a IPADDRESS
VALUE=The new value
This info can be gained by reading the first html-page
(http://ucd-snmp.ucdavis.edu/)
So I have to work a little bit, but if you have any questions
suggestions, just ask.
P.s.: There are some big bugs in the IPACCT-MIB. If you want to use
that, I could send you our fixed version.
Regards
ratz

Hey, as of RFC 1812, subnets of all 0s and all 1s are legal and most routers
do support them. If yer gateway doesn't support all 0 / 1 subnets, you must
be using old software. Maybe there's an upgrade available?

Hi,
Yes, it does, but in a tricky way.
Create a .netrc file in your home directory (possibly the permissions
areto be 600) with the format
machine remote.machine.org login yourlogin password yourpassword
Ater it is done, you can use a command such as
(echo cd /path; echo bin; echo get yourfile) | ftp remote.machine.org
You can also use reget, of course. I recommend also to include the
echo hash
so you know if it is still going.
Important. Do not forget the echo commands.
Good luck, Vilmos

Subject: gated icmp_redirect solutions ? I need some help.
Date: Mon, 12 Jul 1999 08:45:33 GMT
The problem:
I have 3 nic(s) in a linux box. The first nic(eth0) has it's own IP and Gateway. The
second nic(eth1) has it's own IP and Gateway. The third nic(eth2) has a class C IP of
192.168.1.1. ( *never mind on aliasing* ;)
What I am trying to do is avoid some ugly traffic generated by the service ftp and http
serving within one box and have NAT(Masquerade)services along side it with different
IPs
and Gateways.
Thing is eth0's gw is taking over for the eth1's gw. Is there a work around?
I was told to use Gated and ICMP_REDIRECT. I haven't found documentation on these yet.
I run a 2.2.10-ac10 kernel. With Firewall and Masquerading.
(redirect 1) had to add routeing/kernel config for my MASQed boxes to get out. ?
=================
=================
this is my set up for the nic cards.
#! /bin/sh
ifconfig lo 127.0.0.1
#route add -net 127.0.0.0
#
ifconfig eth0 55.5.75.207 netmask 255.255.254.0 up
route add default gw 55.5.74.1 eth0
#
ifconfig eth1 55.9.180.43 netmask 255.255.254.0 up
route add default gw 55.9.180.1 eth1
#
ifconfig eth2 192.168.1.1 netmask 255.255.255.0 up
I have tried simple rules for ipchains just to get it working
So far I have used
##
ipchains -P forward DENY
ipchains -A forward -s 192.168.1.0/24 -j MASQ
or
ipchains -A forward -s 192.168.1.0/24 -i eth1 -j MASQ (was trying to make it listen to
me <g>)
##
with ip_forward & tcp_syncookies set on.
the top MASQ gets me out but using the IP/GW of eth0 (from the MASQed boxes) *needs
routeing in kernel*
the second MASQ doesn't get me anywhere because the eth1's IP and GW are totaly
ignored
cause of eth0..so it's stopping there dead.(this is the same as the top if I didn't
have routeing)
(turned on in the kernel along with MASQ
and FIREWaLLs)
==================
==================
sumed up- I want eth0 to run the everything(ftp/web/ect) but MASQeradeing for me (yeah
I cant
have X number of exter boxes to do these) and I want eth1 to handle its own GW and IP
and let
my other boxes have access to the www). There has to be a way... So that I can have 2
Gateways
each with it's own IP. I think I can handle things if I got past this point. I heard a
few say
I needed to use the gated deamon and ICMP_REDIRECT, I have found nothing on these yet.
Well I tried to be as brief as I could.
I would be very grateful for any help.
Thanks,
Steve Udell

what's in /proc/sys/net/ipv4/ip_dynaddr ?? if it's not 1 then set it to
1 -> echo 1 > /proc/sys/net/ipv4/ip_dynaddr
hope this does the trick...

What is the difference between logging in as root and using su?

Will it handle permissions, links etc?
