Apache does not directly know about physical network connections. It
relies on the underlying OS to handle that. Once you configure Linux to
handle this switch over, it will work for all applications, including
Apache.

I am having a problem updating the Netscape on RH5.2 to Netscape 4.51.
The shell script doesn't seem to like blank lines, when all blank lines
are commented out, it fails when it starts to parse the tar parameters.

The error is probably because httpd can't find a file it is looking
for during start-up. Check the errorlog in the "log" subdir of the
apache tree.
Also, you should probably start apache with the "apachectl" control
script with "# /usr/local/apache/bin/apachectl start "

Hello,
I am desperately looking for help for installing the Diald program.
I am not quit new to Linux, but I didnt succeed in installing Diald.
Also.. when i try to unzip the source and install i get all sorts
of "redefine" warnings and errors.. when i do make depend,
make and make install thereby forfeiting the software all together
The faq's and Howto's and manpages I read did not brought a solution
for me.
They all had a different solution, so now Im totally confused.
I have 2 Windoze machines and 1 Linux server (2.2.1), configures in a
LAN.
I can ping the Linux box and viceversa. It seems to work well.
Now I want those Win-boxes to dialup to my ISP using the Linuxbox as a
dialup server.
I can make a internet-connection on the Linuxbox with chat and pppd
and a script.
Now I want to use Diald to do the job.
Please, can someone explain what config files etc I have to build,
and what the contents is, and where I should place them?
Examples of config file would be great.
I want to use the standard Diald program. No extensions on it or so. I
want to
use the basic program.
I am quit hooked on Linux and desperately want to use diald.
Hope someone can help me.
Thanks in advance

Hi all,
I am fairly new to Linux.
I am running it both at home & at work. My work computer is also on a
network.
So I have it setup dual boot with W95 & Linux2.2.1
Can I browse the NT4.0 server at work?
My sys admin says Im free to do so but only if I can figure it out as he
has no idea how to do so.
I have read many times how windows can hook up to a Linux server but can
the reverse be done?
Our server is netbui & tcp/ip
I am able to ping all the machines at work so I know I have my eth0 card
set up.
Any help or a pointer to a URL that can help me would be appreciated.
Thanks,
Mike

This is also caused by incorrect or missing nameservers. Check your
/etc/resolv.conf for correct entries. Try pinging with numerical
addresses only, if that works, just add the correct DNS entries in the
above file.

I am using linux redhat 5.2 as my firewall, behind my firewall I have got
the rest of my network and my webserver.
I have setup the firewall so all users can browse the net (no problem).
The problem I am having is getting users on the web to see my webserver
NT) . The webserver worked when it was infront of the firewall.
I changed my mx records to point to the firewall now.
No luck
I am having the same problem with my mail server(Exchange).
Does not get mail out side users.
I have been using "ipfwadm" to set my rules with masquerading enabled. Have
have also set the firewall up so that all http traffic coming to my box is
sent to my webserver. Does not work!
What do I do for my web server to be on the net again ( I'm sure the problem
with exchange is similar)
Any help will be appreciated

Brian,
I read your question about diald and win'98 today. I don't have an answer to
your problem, butmaybe you can help me in setting up a similar
infrastructure; I myself tried to configure my linux server and win'98
clients for use with diald but sofar I didn't succeed.
Can you send me some help, specifically I am interested in your following
files:
/etc/ppp/options
diald.conf
Furthermore I am interested in the command you use to start the diald daemon
(which commandline options do you use). Many thanks in advance, your help
will save me a lot of time and headaches!

Shure !
The use of forwarding is not to redirect to another machine, but to
redirect to local another port.
ipchains -A input .... -j REDIRECT !!LOCALPORT!!
You must run some kind of a deamon or proxy to capture the requests from the
hosts outside the firewall and then redirect them to a proper location inside.
Sorry, but I do not know where to get thiese software.

Subject: Re: recvfrom: connection refused
Date: Thu, 25 Mar 1999 16:58:53 GMT
You have found the "enhancement" that is in UDP networking in Linux.
I found this myself several weeks ago and there is a solution.
More information on this is available in RFC1122, sect. 4.1.3.3.
There is also some information on this in the "Unix-socket-faq for network
programming" section 5.4.
There are copies of this available all over the place including:
http://www.cis.ohio-state.edu/hypertext/faq/usenet/unix-faq/socket/faq.html
I was just about to post the solution when I found your question.
So I will post the solution in this reply.
You can turn off this Linux "enhancement" by selecting BSD networking
compatibility mode. Otherwise your application will need to handle these
unusual ICMP recvfrom errors when it sends a UDP message to a IP location
that is not receiving messages.
To select BSD metworking compatibility mode you need to use the undocumented
setsockopt SO_BSDCOMPAT option on the ICMP layer.
This needs to be called sometime after the socket() call and
before the sendto
E.g.
int sock;
sock = socket(...);
.
.
.
int buf = 1;
int len = sizeof(buf);
struct protoent * protoent;
protoent = getprotobyname("icmp");
if (!protoent) {
fprintf(stderr, "Cannot get icmp protocol\n");
}
else {
if (setsockopt(sock, protoent->p_proto, SO_BSDCOMPAT, (char*)&buf, len)
== -1) {
fprintf(stderr, "setsockopt error SO_BSDCOMPAT :%s", strerror(errno));
}
}
That's it...
I hope this solves your problem.
I have spent way too much time getting to the
bottom of this. I hope others find this and
can save some time by doing so.
I wish Linux was documented better.
