Subject: Linux UDP ports above 61000
Date: Mon, 03 May 1999 04:14:15 GMT
I recently got the Blackdown 1.2 java release running under Linux Redhat 5.2.
While porting some networking software, I noticed that the high-numbered
UDP port I had picked out of a hat was failing to allocate. A little
experiment later showed that all UDP ports above 61000, all the way up
to 65335, were failing. The same code under Irix and Windows worked in
the upper port numbers (aside from a couple ports that were being used,
probably by ephemeral ports.)
My question: what's up with the UDP port numbers above 61000? Is this
a blackdown problem, something with the way I've got my Linux
machine configured, or what?
The java code (this is off the top of my head, actual code not handy
right now) looks like this:
/**
* Test program, prints out UDP ports that can't be allocated.
* Compile: javac ClosedPorts.java
* Run: java ClosedPorts
*
*/
import java.net.*;
public class ClosedPorts extends Object
{
public static void main(String args[])
{
DatagramSocket socket;
int portNo = 1024;
while(portNo < 65335)
{
try
{
socket = new DatagramSocket(portNo);
socket.close(); // Close down, prevent too many open at once
}
catch(SocketException se)
{
System.out.println("Unable to open socket " + portNo + " " + se);
}
portNo++;
}
} // end main
} // end class

Subject: Routing to ADSL connection
Date: Sun, 02 May 1999 03:01:39 GMT
I'm having problems using my Linux box as a router to my ADSL Internet
connection.
I've set up a Linux router successfully before, so I'm not a total novice.
I think my problem has to do with using DHCP on my ADSL connection
to the Internet.
I have three ethernet cards, two in my P75 gateway machine,
and one in my P350. All work fine.
I have connectivity between my two machines on my
192.168.2.0 network, and I can reach the Internet on my gateway.
I can't however reach the Internet from my P350 from either WinNT
or Linux (I have both installed on that machine).
I compiled the kernel on my gateway with CONFIG_IP_FORWARD=y on
and CONFIG_FIREWALL=n. I'm running RedHat 5.2.
My P350 route looks like:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
192.168.2.0 * 255.255.255.0 U 0 0 2 eth0
127.0.0.0 * 255.0.0.0 U 0 0 1 lo
default gateway 0.0.0.0 UG 0 0 1 eth0
and on my gateway:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
209.226.80.0 * 255.255.255.0 U 0 0 5 eth0
192.168.2.0 * 255.255.255.0 U 0 0 3 eth1
127.0.0.0 * 255.0.0.0 U 0 0 1 lo
I did nothing to add the 209.226.80.0 route, I assume this is set up by the
DHCP. I find it curious that there is no default route, yet I can reach
arbitrary points on the Internet.
This shows what happens when I try to traceroute on my gateway (looks good)
traceroute to 128.100.8.6 (128.100.8.6), 30 hops max, 40 byte packets

I tried running routed with -d flag and a log file, but didn't get much
other than the routes.
Are there any other tools that might help me, or any kernel flags I don't
know about? Is this any thing to do with using DHCP to resolve an IP
on the gateway machine? Should I have a default route on my gateway machine?
If so what should I give as the gateway?
Any help here would be much appreciated.
Thanks

Subject: Routing by source IP
Date: Mon, 03 May 1999 13:17:06 GMT
Ciao folks !!!
I want to know if it's possible to route an IP packet depending on the
source IP address. I wanna direct all the request coming from a
particular subnet towards a gateway and other requests towards a
second one. But to do this I gotta check up the IP address of the
remote host which did the request.
Is there any program to do that?
D'you know if it ss in project for future versions of kernel? or maybe
for new distributions?
I have a Red Hat 5.1 linux os.

Subject: PPP server setup problem
Date: Mon, 03 May 1999 06:22:57 GMT
Hi all,
I'd like to setup a PPP server at home so I can
dail-in remotely into my home LAN and access
the data.
The problem I'm having is the routing. From my
remote machine, once the PPP connection
established, I can ping the PPP interface IP on
the PPP server from my remote machine. I can
even ping the eth0 interface IP on the PPP server
without problem. However, I cannot ping/connect
to some other machines on the same subnet.
The connection I'd like to achieve looks like:
Remote PPP server
192.168.0.50 <--> PPP IP 192.168.0.1
eth0 IP 192.168.2.20
^

v
LAN (Network 192.168.2.0)
The routing table after PPP established:

what should I do to fix it??

Subject: Re: Networking question regarding two offices seperated by T1
Date: Mon, 3 May 1999 01:45:09 -0500
Two methods:
1. Change address to 192.168.1.x (easy since using DHCP) and dump the
routing on the routers and put them in bridge mode. (horrible choice because
of WAN traffic generated - only an idiot would do it and unfortunately i've
seen a hundred networks configured this way)
2. Leave network as is. Setup SMB browsing between the networks using WINS
on NT or SAMBA. This will allow browsing all resources on both ends of the
network but segregate all traffic except direct connections to the shared
resources (excellent choice with low traffic over WAN - only one system on
each net sends periodic updates of resources to it's WINS partner on the
other LAN.)
DO NOT CHANGE THE SUBNET MASK TO 255.255.0.0 on a class C address
For details on SAMBA see their site us1.samba.org
For detail on WINS see any NT Server reference
If you were brought into consult on this network you should know all the
above. It's basic ip and windows networking!!!

Date: Mon, 03 May 1999 16:26:57 GMT
Your forgetting the most important part (and the answer to the question)
since all three domains will be on one machine, the alias file will not
distinguish the domains.
So [EMAIL PROTECTED] is the same as [EMAIL PROTECTED]
To fix this, you will need to have multiple instances of sendmail for each
domain and alias files.
Unless there is a better way, this is how I do it!

Perhaps you had an older version of bind running prior to the reinstall.
Bind-8.1.2 is included with RedHat 5.2 and the named.conf file format has
changed. Back up your old /etc/named.boot and /etc/named.conf and run the
script file /usr/doc/bind-8.1.2/named-bootconf.pl. You may have to copy
your old named.conf file into the directory of the script and copy the new
named.conf back into /etc. Its been a while since I had to do this...
