Subject: Web Mail Server for Linux?
Date: Sun, 18 Apr 1999 09:59:28 -0500
I run sendmail and Apache on my 2.0.35 Linux server and was wondering if
anyone knew of a solution to permit viewing users' email via a web
connection to the Apache server. For those that have seen it, I'm looking
for something similar to the MS Exchange Server facility that lets users
access their Exchange mail via IE instead of using the Outlook client.
Thanks,
Gray

I am a newcomer to Linux and have the following problem.
I have just installed SuSE 6 on my PC, and have managed to successfully
connect to my ISP. But the problem I have is that when I ping known IP
addresses i.e.
www.demon.net I get a return of 120+ Ms from linux but only 40 to 50 Ms
from
Winblows 98!!.
I am connecting to the same phone number in both OS's and have tried
others.
I cannot see WHY my connection is slower under Linux when both OS's
report a connection speed of 64000k with a com port setting of 115200
set serial to vhi.
I have an External Hayes Accurra ISDN TA which is configured as a modem
and a 16550A serial port. Settings are COM1/ttyS0 irq 4 address 3f8 in
both w98 and linux.
My kernel = 2.0.36 and I have Eide drives 2 off
I have tried a Util called irqtune but to no avail :((
I WOULD DESPERATELY APPRECIATE SOME HELP PLEASE!!!!
Just remove REMOVEME. from e-mail address for reply

Try using the Linux Newbie Administrator's FAQ. Using this, it took under an
hour to set up an arrangement like what you are trying to achieve...
http://www.magma.ca/~bklimas/FAQ.htm#masquerading
I tried the IP_Masq howto, and got thoroughly lost. I never was able to
successfully re-compile the kernel and all that, and the instructions (to
newbie me) where chicken scratch.
However, using the instructions at the website I give had me masquerading
almost instantly, and I had setup the security measures (default policy is
deny, etc) less than an hour later.
It has worked rather well, though ICQ doesn't work correctly inside the local
network. (But everything else does)
Hope this helps.

Jayasuthan,
Thank you for your response.
A few people have recommended compiling my own kernel with the NE2000 driver,
but why go to such an extreme simply to install an ethernet card? There must
be a better way.

Oops, since you have both a 3c509b and 3c905b I got confused as
to which one was causing you problems! In other words, I thought
your problem was with the 3c509b, not the other one.

I'll probably will just get another card with the hope that someday the
driver for this "new" card will work reliably. I have used the same card on
my Win95 machines with no problems so I think it's just a driver problem.
For those interested...The Linksys LNE100TX (Etherfast 10/100 LAN Card) use
to have a DEC chip but has switched to Lite-on LC82C169 chip which is like
the DEC except that it doesn't work reliably with the current tulip driver
(V0.91 4-14-99). I'm sure in time this will be fixed.

This is from your previous post:

According to my Running Linux book the variable where you have /dev/null

Please clarify this, should the *home directory* be /dev/null or should
I stick another : in before it to make it the shell ?

I have @Home via TCI. They do allow (for the moment) a maximum of 3
assigned addresses. I got mine when it was still a beta offering, but
now you have to pay approx. $5 for each of the two additional IP
addresses. If you are also connecting a WindowsXX box you can use their
proprietary software to connect to their Member Services page and select
the Home Network option and see what it says. Of course, if you have
more than 3 machines or don't want to pay extra, just use a proxy or
masquerading. After all, you don't want others to think you're pro-M$,
do you?

Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit
I have two questions:
For my home:
I have a RedHat 5.2 installed. I have compiled my kernel with all
support for Ip masq, forwarding, firewalling ... (I haven't understand
what they all are) and I have tried to go to Internet from my NT4 behind
my Linux Box.
Of course I can't get out!! I can ping my Linux eth0 and also my ppp0
but can't ping anything outside.
I'm interested in using Ip masq and have heard of the Ipchains program.
Is that better than Ipfwadm?
For my job:
There is a way to permit or deny not only a workstation but olsa a user
to go through the firewall?
I have more than one private net with a Linux box as gateway to the
router.
I need a system that will let me grant access to the router from my
internal networks deciding on ip# and user of machine. All internal nets
are Win Nt or 98.
Thanks a lot

Well, I know that you can do this with 3c5x9cfg.exe (the setup program
for the 3c5x9 cards) using the /nopnp switch, but that doesn�t seem to
work with 3c90xcfg.exe (the one for the 3c90x cards). Could I maybe
somehow convince 3c5x9cfg.exe to work with my 3c900 card?
Hints, anyone?

Hello Yossi,
The Realtek 8029 chip is an NE2000 compatible chip.
I think your card is an PCI card, so you should take the NE2K-PCI
driver, if you dont have this driver availliable, you can use the
standard NE2000 driver, but you need to give the Adress and the IRQ
as commandline Parameter.
You can find them if you use the card under WIN95 in Device Manager
I don't use slackware, but i think they have a loadable module for
ne2kpci with their distribution.
