Very good points, although I'm a HUGE *NIX fan... There are several ICQ
clients for *NIX, which I hear are pretty good, athough I think that
they're still missing a few of the features of the new client. I'd
really like to see somebody port AIM to *NIX, since that's the best 2
person chat client that I've found, and it does really well with
firewalls since it uses almost only UDP, from what I've seen.

I have recieved a few e-mails asking for help using my DHCP/DNS scripts
with Bind 8.2. I have two things to say:
1. 8.1,2 works fine so I am installing 8.2 on a test server this week so I
can figure out what is wrong.
2. If you write me for help, use a valid return address. Otherwise I am
going to figure you are too fscking stupid to be running any kind of
server.

Do not use GTE as your ISP. What the assholes at GTE will not tell you is
that they will pull an ADSL line to you home and connect you to a non-GTE
ISP's pop. I am using ADSL with GTE as the carrier but California Prime
Line as my ISP. Works great.
Go to: http://www.gte.com/dsl/partisp.html and find an ISP that doesn't
think it is too good to take your money...

Not as such (afaik), although you can log only SYN packates that
initiate a connection by adding the -y options.

Of course, it's possible. How much are you prepared to spend? :}
>I know commercial packages provide this functionality...
See above- loggin SYN packets will show connections attempted. If you
want something more complex than that, you have to snoop the connect
and see when it establishes and completes, which isn't really
trivial. Perhaps enforcing the use of a proxy might be a better
solution?

Redhat has no more security problems than any other distro and, so far,
Redhat has been pretty good at fixing them. =
Your basic aim with any server OS should be to turn off any funtions you =
do
not need and restrict access to the rest.

Subject: Ethernet Trouble between desktop and laptop
Date: Mon, 07 Jun 1999 03:47:21 GMT
Hello everyone!
I successfully installed Linux via PLIP after 9 hours of grief. Turns
out I had the wrong netmask on the laptop (it was 255.255.255.0 and
the route command on the desktop showed it should be 255.255.255.255,
sigh). Anyways, it's on to a new adventure: ethernet! PLIP is too
slow and since I got a free ethernet card for the laptop and the
desktop and the crossover cable was only $2, I had to try to get this
network started.
First, let me describe the laptop. It is a 486 Magitronic with Linux
2.0.36 running on it. The PC Card is a 3com 3c574. Linux saw it
during the installation and installs a module at boot for me, it's
there. This card was given to me by a friend and was pulled from a
working laptop. So, after running the NET-3-HOWTO, I issued the
following commands:
ifconfig eth0 192.168.0.2 netmask 255.255.255.255 up
route add -net 192.168.0.1 netmask 255.255.255.255 eth0
route add default gw 192.168.0.254 (this gives an error==> SIOCADDRT:
Network is unreachable)
These are some of the files on the laptop:
/etc/exports
/ 192.168.0.1
/etc/hosts.allow
ALL:ALL
/etc/resolv.conf
domain leinss.com
search leinss.com desktop.leinss.com
nameserver 192.168.0.1
nameserver 192.168.0.2
/etc/hosts
127.0.0.1 locahost localhost.leinss.com
192.168.0.1 desktop.leinss.com desktop
192.168.0.2 laptop.leinss.com
/etc/networks
loopnet 127.0.0.0
localnet 192.168.0.0
The route command gives the following
Destination Gateway Genmask Flag/Metric/Ref
laptop.leinss.com * 255.255.255.255 U/0/0 eth0
desktop.leinss.com * 255.255.255.255 U/0/0 eth0
loopnet * 255.0.0.0 U/0/0 lo
The ifconfig command gives
inet addr: 192.168.0.2 Bcast: 192.168.0.2 netmask 255.255.255.255
=================================================
Ok, now for the desktop. Don't laugh, but my other friend gave me an
old Ethercard WD8013 Elite Plus, an old combo ISA card made by SMC.
The card is at least 5 years old. Linux sees it fine and runs fine
under the diagnostic programs under both Windows and Linux. Here are
the files for the desktop
/etc/exports
/ 192.168.0.2
/etc/hosts.allow
ALL:ALL
/etc/resolv.conf
domain leinss.com
search leinss.com desktop.leinss.com laptop.leinss.com
nameserver 192.168.0.1
nameserver 192.168.0.2
/etc/hosts
127.0.0.1 localhost localhost.leinss.com
192.168.0.2 laptop.leinss.com
192.168.0.1 desktop.leinss.com desktop
/etc/networks
loopnet 127.0.0.0
localnet 192.168.0.0
Again, I issue the magicial ifconfig stuff:
ifconfig eth0 192.168.0.1 netmask 255.255.255.255 up
route add -net 192.168.0.2 netmask 255.255.255.255 eth0
(After adding this line and then running route, route hangs. Yet, if
I run route -n, it gives me 192.168.0.2/ 0.0.0.0/ 255.255.255.255 in
the route table right away???)
route add default gw 192.168.0.254 (this gives an error==> SIOCADDRT:
Network is unreachable)
The route table is as follows:
Destination Gateway Genmask
192.168.0.1 0.0.0.0 255.255.255.255
192.168.0.2 0.0.0.0 255.255.255.255
loopnet 127.0.0.0 255.255.255.255
The ifconfig shows:
inet addr: 192.168.0.1 Bcast 192.168.0.1 netmask 255.255.255.255
===================================================
Wow, that was long winded! Okay, so, the thing is, when I run
ifconfig on both, the TX/RX packets are 0. Even when I had the
netmask wrong on the laptop, PLIP showed that packets were being sent
back and forth, yet nothing is happening here. I tried two crossover
cables that we supposedly tested by the guy I brought them from.
So, does this sound like the ethernet card in my desktop is bad, too
old or am I doing some grossly wrong in the above configuration? Any
help apprecatied.
TIA,
Adam

Subject: Connection using PAP authentication fails -- please help (more info)
Date: Mon, 7 Jun 1999 09:56:36 +0530
Hi,
I have a Redhat Linux 5.2 system. I was connecting to my ISP using the
traditional
username-password login procedure.
Recently, my ISP started supporting PAP as well as login. So I made the
necessary
changes and tried but somehow it does not work.
I am attaching all the scripts that I use.
When I was logging in to my ISP using the Login process, my username was of
the form
user@md3.
I tried placing the 'name' value in /etc/ppp/options and all other relevant
places as 'user' and
'user@md3' and it still is not working.

**********************************************************************
Also I had to start PPP on the remote server after logging in. But now what
should I do to mimic that??
I read in the PPP-HOWTO that getting a 'serial link not 8 bit clean' error
may be due to that.
Thanks for your help

I'm seeing the same results. In addition it can have woeful
performance when reading too. In one test, smbclient to
a decrepit NT box was almost 100 times faster then
tar cf - <nfs mounted directory> | (cd foo; tar xf -)
Simple read/write tests confirm the problem. In one
case it took 760s to write 42 Mb to a Sol 2.6
server, 560s to a 2.5.1 server. This normally takes
about 50s on our network b/w workstations. When
reading from Sol 2.5.1 it took 143s whereas a Sol
client will do the read in 50s. However, Sol reading
or writing from/to Linux has no problem. The problems
only occur when linus is the NFS client.
These test were done with a Dell Poweredge 2300/
400Mhz PII using RedHat 5.2 and repeated using 6.0
This is serious, something has to be done about it.

Subject: DNEWS 5.0 News Server Mthly Pointer to FAQ
Date: Mon, 07 Jun 1999 05:37:45 GMT
This message is a brief description of the DNEWS 5.0 News Server
features and a pointer to the FAQ and binary areas.
DNEWS is a high performance NNTP News Server. It is suitable
for large and small ISP's and Corporate Intranets. DNEWS is
available for all common operating systems, installs easily and
is designed to run unattended.
Design :
Database : DNEWS incorporates a database specifically
designed for News, enabling DNEWS to handle full news feeds
more efficiently and faster than other news server software.
This is important as news volumes continue to grow rapidly.
DNEWS can provide significant performance improvements
particularly where resources are limited.
Dynamic Sucking Feed Option: In addition to traditional news
feed options DNEWS also provides the unique Dynamic Feed
option. A Dynamic News Feed offers business and smaller sites
several important advantages over traditional full or
partial news feeds. The Dynamic Feed can deliver enormous
savings in Network bandwidth and diskspace while providing all
the advantages of a full news feed.
Performance is significantly enhanced as the high redundancy
of the full feed is automatically eliminated. Unlike the older
traditional partial feed a Dynamic Feed does not require users
access to be limited or the maintenance of updating selected
groups to meet users changing needs.
By dynamically reflecting users reading habits the server
automatically only gets and maintains those news
groups that users actually want to read. In this way users
retains all the advantages of the full news feed while
enormous saving in network bandwidth and diskspace are
possible.
The process is completely automatic so there is no
ongoing administration .
News Reader Efficiency: The advanced design significantly improves
news server efficiency. On similar Hardware DNEWS will
typically support 2 times as many news readers per server
with the same fast interactive response time.
Scalability: Designed for high scalability DNEWS design will
handle 0-60 Gig news spools most efficiently. Can be
configured with 2-10 Multiple Server processes on single
server each handling 50-200 concurrent users.
DNEWS can be configured to take multiple full news feeds
and up to 16 dynamic suck feeds and can efficiently send
multiple full feeds with built-in Live feed technology.
Easy Installation and Management: Designed to run unattended
DNEWS is easy to install with virtually no ongoing management.
Key Features:
Easy Installation - totally configurable without recompiling.
Low Maintenance - designed to run unattended.
Support for Multiple IHAVE Feeds
Support for Multiple Dynamic Suck Feeds
Built in Live Feeds Technology for sending full news feeds to other
servers with the efficiency of a news router.
News to Web Gateway , for putting news onto web pages , with full
text searching .
New to Mail Gateways (both ways)
PGP authentication (optional)
Flexible Access and Security options for reading and posting.
Flexible Expire Options allowing intelligently response to number of
items and available diskspace.
Advanced 'SPAM' detection and filtering mechanisms.
Email confirmation of posts.
XOVER extensions implemented in software removing the need for a
separate ' XOVER' database
Streaming extensions are built in speeding up feed throughput
