The settings are invalid. Your netmask does not fit the gateway's
address - presently, it's on another subnet than your own IP address,
which means that the gateway can not be reached at all.
Try a netmask of 255.255.0.0 instead.

I'm not exactly sure what your are looking for. What behavior
are you trying to modify? The call sys_syslog in printk.c is
doing the writing and its called all over the place. There is
not syslogd.c what I know of.

Date: Sat, 13 Feb 1999 11:33:05 -0500
Greetings all,
I recently setup a file server running Linux (RedHat 5.2). The network
hardware fully supports 100 Mbits and Samba is running so that WIn95
workstations and share files on server. (the create mode is set to 0766).
Copying, saving, etc is pretty quick except for one thing; I have shared
Access databases (.mdb) located on the Linux server that are used
simultaneously by several users and saving operations that normally should
only take 3-10 seconds now take 3 to 10 minutes! What's going on? Any
suggestions?
Thanks for the advice,

Do what I did. I had him install it the win95 PC and then I had moved it
over within a half hour after he had left. By the way, he offered to
install it on the linux box and didn't give a darn about it. Just something
to look for from your installer. You'll want to do it yourself though.

Yup. You'll need to install another NIC card on your linux box and chain
your other network to it. Linux is well suited to it. Setup your
hosts.allow and hosts.deny for security and use ipfwadm judiciously as well.

Don't lisen to them. the cable compaine does not know what they are talking
about. I have tci@home in my linux server. it works great. What you do is
put a second network card into your linux machine. than you plug the cable
modem into second card. you setup the linux box so that the cable modem is a
gateway.

Hi, I am new in this list, i�ve installed linux RedHAt on my machine(dual

me some headache!
I confugured the modem on /dev/cua1 and it is dialing to the ISP but when
the message of "connecting to the network" appears it gives a message "pppd

Date: Sat, 13 Feb 1999 17:02:12 -0000
Having read all the threads here I would have to agree whole heartedly to
almost everything said.
I run a 22 PC network with MS Small Business Server (includes Exchange 5.5)
controlling most things.
Outlook 97 has caused me endless problems with it crashing and refusing to
co-operate with Netscape.
Having upgraded to Outlook 98 I still am totally unsatisfied with the
reliability of these clients.
As for Exchange, it frustrates me to hell that there is no decent support
for an ISDN network dial-up solution.
Either you use a modem or you use a leased line, if you're stuck in the
middle you end up with big ISDN bills.
I have worked around that problem by using scheduled batches to stop and
start the internet mail service, although
that isn't the best solution as the mail server sometimes gives up on
restarting before the ISDN router has finished connecting.
Also Exchange dislikes attachments and quite often garbages them or loses
them completely!
I would happily move to something else although I doubt my users would cope
with the change.
What are the options for client/server mail on Linux, especially on the
client side?

Subject: slow telnet logins in RH 5.2 (again) vs. Slackware/Caldera
Date: 13 Feb 1999 16:39:54 GMT
I just installed RedHat 5.2 on a Dell 75/40/3BG machine that will
eventually be a mail server. Like many others I experienced the "slow
telnet logins" problem, went to Deja News, and read some suggestions
about adding the inbound machine's address to the hosts file.
This is all well and good and may get around the problem, but consider
the following: when running Slackware 3.2 there is NO slow telnet
problem. OBVIOUSLY the Slackware distribution doesn't come
pre-configured with all the other hosts in my network (or anyone
else's!) and it works just fine, so there's got to be another, better
answer to this problem. I've also read that Caldera has no such
problems as well. It has to be something peculiar to Red Hat.
I am just starting out setting up this mail server and am learning a
lot in the process. However I would rather not deal with a
distribution that has a lot of weirdities like this telnet thing.
Honestly, telnetting into the machine was the first thing I tried and
ran into this problem, not a good sign IMHO.
Slackware install was not as smooth as RH. Once the install was done,
there were fewer nasties along the way with Slackware and things worked
pretty much the way the HOWTOs said they would. I may just scrap RH
and go back to Slackware but support is a concern as well (RH seems to
have a pretty decent support infrastructure)
I'd be interested in hearing anyone else's experiences & thoughts about
any of these issues.

Date: Sat, 13 Feb 1999 16:35:50 +0000
I am setting up the TIS firewall toolkit on RedHat 5.2 (kernel 2.0.36)
I have read and reread the various FAQs (DNS, Firewall, TIS), but have
hit a roadblock.
I have set up the htt-gw, and have pointed my browser to the proxy
machine. The proxy machine is also running a name server.
If, in my browser, I put in a URL, the TIS proxy server comes back with
'hostname unknown' (the full message in the syslog is 'failed to connect
to http server www.tis.com'(80))
However, the name server is working properly - pinging www.tis.com
brings back the correct address. Furthermore, plugging the ip address
directly into the URL in the browser works OK via the proxy.
Any advice gratefully received.

Thousands of people do this EVERY DAY with linux. Actually I do it EVERY
day
with Linux. What you describe you want to do is EXACTLY AND I MEAN EXACTLY
what Linux users do every day to dailup to the internet!!!
Read the thousands of FAQs on PPP connections and dialups. Read the
thousands
of FAQs on bridges, routers, gateways.
What you need:
1. PPP Server at location 1 (Read the DIP FAQs)
2. PPP Server at location 2 (Again, read the DIP FAQs)
3. Routing strategies (Read the route and bind FAQs)
4. DNS server (you will want this probably) (Read FAQs on named)
5. Samba (just to keep your Win95 boxes connected).
6. .....etc.
This is not something to jump into lightly. But this is only one of the
things Linux does best.
Where to start you ask?
1. Install and configure linux on 2 boxes.
2. Put modems in both and Ethernet Cards in both.
2a. Assign network cards ip addresses 192.168.0.1 and 192.168.1.1
(You will have two subnets)
2b. Assign the modem cards 10.0.0.1 and 10.0.1.1
(You will have two more PPP subnets to link)
3. Put both machines on your desk right next to each other and get two
phone lines and
plug them in to the modems.
4. Practice with PPP dialup server/client connects until you get bo
Note: This is only ONE way out of thousands and my not be the best way.
Read the FAQs
You can do this without the 10.0 network, as it's an approach only!
Machine 1 Machine 2
Ethernet NIC Modem Modem Ethernet NIC
192.168.0.1 10.0.0.1 10.0.1.1 192.168.1.1
OR
Machine 1 Machine 2
Ethernet NIC Modem Modem Ethernet NIC
192.168.0.2 192.168.0.1 192.168.1.1 192.168.1.2
Ether way it's up to you. My approach is always the first one
so that nothing gets confused with the sub-nets. There are
hundreds of other configurations that will work too. Just try
one out.
Maybe someone will post a better solution...I'm sure one exists!
Good Luck!

Mine definitely isn't swapping. In fact I haven't managed to get it to
swap except when I tested it (reserving 128Mb with malloc and then writing
to all of it, it took a /long/ time), 48Mb is ample for what I do.

The difference I've seen between receiving and sending may be an illusion,
I haven't managed to prove it one way or the other.

That's certainly the case in the later stages, you might just have missed
the intervening bit where packets stopped in one direction first.

Ah, I have it with both my ISPs (BaWueNet in Germany and Demon Internet in
Britain). Originally I thought it was a modem problem with BaWueNet (in
spite of the fact that the same modem happily does PPP for hours under DOS
and Windows), but I tried it in Britain with the same results.
Well, it at least looks like a real problem, not my imagination or a hex
on my machine. That helps...

I just installed KDE 1.1 for RH5.2 (very nice, I must say), but when I

This never happened before I installed KDE.
