Date: Sun, 15 Aug 1999 23:52:05 GMT
In order to "kill" a connection, you would need to know what port/app they
intruder was using. Then use a command like "ps auwxf" to find out if there
are any associated processes involved in making that connection. For
instance, telnet uses port 23, and ftp uses ports 20/21. If an intruder was
using telnet, then you would see an associated in.telnetd process that was
"spawned" by the inetd process.
Using Telnet as an example, the following would illustrate the process tree
for a telnet session (your process ID's would be different.
[scowles@voyager scowles]$ ps auwxf | more

In the above, process 362 (inetd, the parent) spawned child process 6678
(in.telnetd) which in turn spawned child process 6679 (login) which in turn
spawned child process 6680 (bash) which in turn spawned the ps|more commands
(I typed those in). The reason you need to know the parent/child
relationship comes into play when you want to "kill" a process.
In this case, you would want to kill the processes in reverse order. By NOT
killing a process tree in reverse order, you stand a chance of a child
process going "defunct". Which is not good. A defunct process is typically a
child process that tried to return to the parent process (like typing exit
or logout), but the parent process had already died. I have had cases where
a defunct process could not be killed (even using kill -9). I had to reboot
in order to get rid of the defunct <groan>
In the above example, I would kill the intruders telnet session by issuing
the following command (as root)
kill -HUP 6680
The -HUP will send the proper Hangup Signal to all other parent process in
the stack. There should be no reason to issue the following commands. They
should all dissapear.
kill -HUP 6679
kill -HUP 6678
If you want to limit access to your Linux box (from the internet) add the
following to your /etc/hosts.allow and /etc/hosts.deny files. This will keep
a lot (not all) of the intruders from gaining access to your system.
ipchains commands can help with the rest of the "script kiddies" out there.
#
# hosts.allow This file describes the names of the hosts which are
# allowed to use the local INET services, as decided
# by the '/usr/sbin/tcpd' server.
#
# Allow only computers on the 192.168.9.0/24 (Local) network access to all
services
ALL: 192.168.9.
#
# hosts.deny This file describes the names of the hosts which are
# *not* allowed to use the local INET services, as decided
# by the '/usr/sbin/tcpd' server.
#
# Disallow ALL access to this system by default. NOTE: hosts.allow is

I've got limited experience with RedHat 5.2 (kernel 2.0.36), and in the
near future, I will be building a computer for use as a web server at
work. I work in a small office that publishes newsletters for various
clients, and we are exploring the possibility of publishing our
newsletters on the web. This part is easy enough.
But, I'd like to put a huge drive in the computer (12 gig minimum) and use
the Linux box as a file server for the rest of the computers in our
office, which are all Macs. From what I've heard, this is possible, but I
would like to know how easy or hard this is. I know Macs forwards and
backwards and upside down, so configuration on that end is not an issue.
Thanks for all the help, people.
Please e-mail replies. Thank you.

For 25 PCs masq will work like a charm. I have a friend how implemented
the same thing in an office about the size of yours. They only had one IP
address to start out with and their connection was ISDN.
I think it would be better to have masq going as you talking about and
have the Linux box also do firewalling. This would be much better then each
pc having its own 'real' IP for which crackers can try to hack on.
So I believe if the Linux box is setup right (sounds like you have that all
set) you will not notice any problems with speed. I think it can be safer
for your internal lan as well.

"ipchains -D" will delete the matching rule. That's probably not what you
had in mind.
>/sbin/ipchains: invalid mask `213' specified
That's because your netmask has to be either dotted-quad or a single
number from 0 to 32 representing the number of "1" bits in the mask.

There is no method to include an address range in the firewall. You may
be able to accomplish the same thing by banning the smallest complete
subnet that contains them all, or break the list into several even smaller
subnets and ban each one.

Actually, your speed is determined primarily by the bandwith of your
connection (64K), and has little to do with whether the IP addresses are
real or not.
You may be affected, however, by other traffic on your internal network. At
my office, the network is primarily used for Microsoft Networking, with
lots of print jobs etc., so I sometimes see slowdowns due to general net
loading.

Before you configure anything as static or dynamic, you should call your ISP and
ask them how you ip is allocated. Don't make assumptions when a quick call will
do. As far as the ip addresses, you need to put in the ip addresses of the
Domain Name Servers that your IP uses. Just ask them what they are and they will
tell you.

Does anyone know of a way to create a global address list on a linux (samba)
server that exchange clients would be able to use to check names with?
