Subject: Resolving IPs
Date: Mon, 16 Aug 1999 14:36:57 -0700
I'm trying to cut down traffic on unauthorized sites for our network.
Many of the sites are unresolveable sites (unresolveable by me anyway)
and show IP addresses only. If I try to access the site from a web
browser, the browser usually times out.
Anyone know how to resolve this type of IP address?
Another question:
I've been using tcpdump to monitor and capture traffic. Some of the
sites are only accessable if you use the fully qualified name. But they
actually resolve to a different name. If I try to go to the site it
resolves to (the IP address) I'm taken to a different site. Anyone have
any ideas why or how this happens?
i.e.
(I found this site at Yahoo while scanning tcpdump)
shorthair.com (a site about dogs)
nslookup shorthair.com returns
Non-authoritative answer:
Name: shorthair.com
Address: 192.41.43.186
nslookup 192.41.43.186 returns:
Name: displayservice.com
Address: 192.41.43.186
The only way to get to the site is by using "shorthair.com". Any other
means (IP or displayservice.com) go to a different web page.

If you want to ping the other end to keep the connection open.
The output from ping will goto >/dev/null, you won't see it.
Ping -i 60 = send ping every 60 seconds to remote = $5.

Subject: Do Two PCMCIA NICS coexist?
Date: Mon, 16 Aug 1999 23:15:36 GMT
I'm trying (and having little success) to set up an old 486 laptop as
a Linux masquerading router through my Cable Modem.
My Hardware: 486DX2/50, 20 MB, 2 GB, two Xircom PS/CE2 PCMCIA Ethernet
NICS.
My software: RedHat 6.0, box stock.
My Intended configuration:
Eth0: address 192.168.1.1 connected to local net (192.168.x.x)
Eth1: address (withheld) connected to Cable Modem (also withheld, call
it CM_Addr)
All local traffic masqueraded to the Internet.
No services running on the Linux box.
My symptoms:
PING to the local network works great.
PING to the Cable modem, I can see (using a packet capture tool) Eth1
transmit an ARP looking for the Modem. I can see the Modem respond.
Then I see Eth1 transmit an ARP (ad infinitum). It appears as though
Eth1 is either igoring the incoming packets, or never receiving them.
All the Addresses (MAC and IP) look as expected.
ARPing or PINGing Eth1 from the Cable Modem network elicits no
response from the card.
PINGing an Internet address from a host on the Local network
(configured with the Linux box as it's router) causes Eth1 to ARP for
the Cable Modem. Eth1 ignores the replies coming back.
IFCONFIG never shows any Transmit or Receive packets on Eth1; they
seem to get assigned to lo, the loopback interface. Eth0 counts
correctly.
My troubleshooting:
Route shows:
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.1 * 255.255.255.255 UH 0 0 0 eth0
(withheld) * 255.255.255.255 UH 0 0 0 eth1
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
(withheld).0 * 255.255.255.0 U 0 0 0 eth1
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
default (CM_Addr) 0.0.0.0 UG 0 0 0 eth1
IPCHAINS -L shows:
Chain input (policy ACCEPT)
Chain forward (policy ACCEPT)
Chain output (policy ACCEPT)
The same symptoms occur after executing:
ipchains -A forward -i eth1 -j MASQ
Thinking I might have a bad card, I removed Eth0 (but didn't touch
Eth1), and rebooted. Eth1 was now reassigned as Eth0 (as expected),
and worked perfectly on the local network (once the patch cable was
swapped; I left the dongle attached). I tested the patch cables to
make sure they hadn't broken, and they were OK.
My guesses:
1. A driver conflict exists because two identical cards are installed
that keeps the Receive interrupt from the second card from being
recognized.
2. I don't have something configured correctly. I have enabled packet
forwarding using
"echo "1" > /proc/sys/net/ipv4/ip_forward"
as well as by changing
FORWARD_IPV4 to TRUE in /etc/sysconfig/network
My questions:
1. Can two identical PCMCIA cards, specifically two Xircom PS/CE2
cards, co-exist and function?
2. Is there anything obviously wrong with my configuration?
Thanks,
/frank

Not the politically correct answer in this newsgroup, but if you must
share a net connection via an NT box, check into SyGate.

At least here, athome specifies "no servers"; your contract may differ.
Also, since athome owns the ip address, you will have to coordinate through
them, or reverse lookup on your address won't work.

What does the rpcinfo on the SUN tell you?
If you are trying to mount an export from the SUN to the LINUX,
wouldn't the error tell you that something on the SUN is not running

Looks very much like you haven't got a ftp server with
a builtin ls. You can grab the latest fileutils package
from any GNU mirror and compile a static version. Copy
it to ~ftp/bin/ls and done you are.
Yes, it is possible too to use a dynamic linked version,
but then you need much more in ~ftp.
As a quick test you can do this ...
main() { puts( "foo" ); }
... compile it with -static and copy the binary
to ~ftp/bin/ls. If "foo" shows up when you do a
ls you know for sure.

Subject: Diald, masquerading and dynamic IP addresses
Date: Mon, 16 Aug 1999 23:31:25 +0100
I am trying to setup a Linux server for a small home network with about four
machines, unfortunately the ISP that I use is running using dynamic IP
addressing. I have managed to setup diald and it works great and all of the
appropriate masquerading and routing is done using the addroute script,
however the packets which seem to start the connection do not get through to
their destination or the TCP connection is reset. However if any packets
are sent after the initial connection they are fine.
As far as I can tell I have followed all of the directions in the
README.masq file, does anyone have a sample configuration that I could view?
Any help would be appreciated,

If you are logging in as a native user, most likely that user is a
member of the USERS group and, because all other users are also
members, the account can see other people's files (depending on the
chmod mask used).
What you need is to allow anonymous access and keep it well
controlled. You need to read the man pages on in.ftpd and ftpaccess.

Hi Doug,
Please try JProxyma( http://www.intellectronix.com/jpro/ ).
It takes minutes to install on your NT machine. You can
also run it on your Linux box(or any Java-enabled machine)
and turn your Linux computer into your Internet gateway as
Andrey suggested. If you run JProxyma on Linux I strongly
recommend that you use IBM's Java virtual machine.
There are several reasons why you may be better off running
a proxy server rather than using IP-Masquerading:
- a caching proxy server reduces network traffic and improves
content access time
- proxy servers often provide many useful security features.
- imho, proxy servers are simpler to install and easier to
manage/administer than doing IP-Masquerading. if
you choose to run a proxy server you will not need any
luck (-:
Hope this helps.

Subject: ncpmount will not mount on bootup
Date: Mon, 16 Aug 1999 21:35:41 -0400
Hi all,
I am using ncpmount to connect to a netware filesystem. The problem is,
that ncpmount will not mount if it is invoked from rc.local or from a
script started from there. If I invoke it manually after the boot, it
mounts just fine. I am guessing some problem with the process group or
/etc/utmp or something of that sort. Any ideas ?
Thanks in adv, Fritz

(All the following presumes that you have compiled kernel or module
support for the 3c509.o module Mine is compiled into kernel 2.2.5)
I have dual 509's running in my home network. The first thing you do
is in linux
cat /proc/interrupts
that gives you a list of IRQs pick 2 that are not used
cat /proc/ioports
that gives you the io addresses that are used pick two unused ones.
next put ONE card in and boot to DOS use the 3COM utility/diags/setup
disk #2 (not #1 it is windows) do an info on the card. Write down
its mac address that will be a long string maybe called hardware
address. write that down. Now set the IRQ to an unused one and the
io to an unused one. Disable the PNP.
Shut down/power down.
Exchange cards and repeat that procedure fro card #2
Shut down, install both cards noting which card is above or first as
regards that hardware address.
Boot linux
run linuxconf got ot networking basic defaults and set the card with
the LOWEST hardware address as eth0 do not put in the IRQ or the io
address Do give it the lowest IP address
move down to #2 and enable that as eth1 also NO IRQ or ioaddr.
Remember to give your hostname at the top.
exit and reboot
Watch carefully during boot you shuld get an ok for first lo then eth0
and then eth1
At this point you are ready to tackle the network
DO NOT BOOT those cards under windows, it will reset the PnP.
