Reply-To: [EMAIL PROTECTED]
Hello all.
I have a RH 5.2 machine set up. It installed pretty well. Now I'm trying to
get bind working properly.
First off, this little network is NOT connected to the internet. So, I made up
the IP network number and domain. Since it's not connected, it doesn't matter.
Anyway, I naively went in and tried setting up named.boot the way it was on my
old linux machine. (I'm not sure it worked there either.) Anyway I tried and
tried editing this file and restarting named. But alas, nothing ever changed.
Then, I figured out that named was using named.conf instead. Newer version of
Bind. I says "Ha hah! I've got it!" Then I settled down to figure out
named.conf. After searching on the news groups, and the like I found about the
conversion script. I ran it, and everything seemed wonderful.
But I'm not sure.
When I do a nslookup on a host name, I get, what I think, is a proper
response. For example:
# nslookup station000
Server: glwings.com
Address: 192.123.123.1
Name: station000.glwings.com
Address: 192.123.123.100
When I do a reverse lookup I get:
# nslookup 192.123.123.100
Server: glwings.com
Address: 192.123.123.1
Name: station000.glwings.com
Address: 192.123.123.100
Now, this, to me, looks right. But in the reverse file, for station000, I have
the following entry: "100 IN PTR station000.glwings.com." Including the
trailing period.
Next, I test the same commands against another computer I have defined.
# nslookup gl1200
Server: glwings.com
Address: 192.123.123.1
Name: gl1200.glwings.com
Address: 102.123.123.3
# nslookup 192.123.123.3
Server: glwings.com
Address: 192.123.123.1
Name: gl1200.123.123.192.in-addr.arpa
Address 192.123.123.3
For "gl1200" I have in the reverse lookup file: "3 IN PTR gl1200"
I believe that I shouldn't have to have the fully qualified domain name at the
end of each node name.
Let's see...
My named.conf file looks like:
options {
directory "/var/named";
};
zone "." {
type hint;
file "named.ca";
};
zone "glwings.com" {
type master;
file "glwings.hosts";
};
zone "123.123.192.in-addr.arpa" {
type master;
file "glwings.reverse";
};
zone "0.0.127.in-addr.arpa"
type master;
file "local.reverse";
};
My named.boot file looks like:
directory /var/named
cache . named.ca
primary glwings.com glwings.com
primary 123.123.192.in-addr.arpa glwings.reverse
primary 0.0.127.in-addr.arpa local.reverse
The glwings.hosts file looks like the following. I took some lines out for
brevity.
@ IN SOA glwings.com. hostmaster.glwings.com. (
1 ; serial number
10800 ; refresh rate (3
hours)
1800 ; retry (30 minutes)
1209600 ; expire (2 weeks)
604800) ; minimum (1 week)
IN NS glwings.com.
IN MX 10 email
gl1000 IN A 192.123.123.1
glwings.com. IN A 192.123.123.1
;
; Workstations
;
station000 IN A 192.123.123.100
station001 IN A 192.123.123.101
The glwings.reverse file looks like: (Also lines removed)
; reverse mappings for glwings.com
; revision history: [EMAIL PROTECTED], January 21, 1999
@ IN SOA glwings.com. hostmaster.glwings.com. (
1 ; serial number
10800 ; refresh rate (3
hours)

minutes)
1209600 ; expire (2 weeks)
604800 ) ; minimum (1 week)
IN NS glwings.com.
1 IN PTR glwings.com.
2 IN PTR gl1100
3 IN PTR gl1200
;
; network workstations
;
100 IN PTR station000.glwings.com.
101 IN PTR station001
I guess the first question I have is, is the behavior I have listed about
normal? Is nslookup and dns working properly? I can telnet to this node, ping
it, yadda yadda. And ping from it. So I know I'm at least close to the proper
setup.
The second question I have is, if it's not set up correctly how do I fix it?
When I telnet into this machine from station000, it says "last login from
station000" That is with it's current settings. But if I remove the domain
name portion of the reverse address in the reverse file it says "last login
from "station000.123.123.192.in-addr.arpa."
Anyway, I hope you can help me out. I've got a bunch of books I've been
reading. But I haven't gotten the BIND book yet. That's next on my list.
Thanks in advance,
Lyndon

Since the limitations of NFS on the 2.0.x series of kernel were well know
why didn't you go with something like FreeBSD? They have (more or less) the
same philosophy as the Linux people and for NFS it would most likely beat
Linux hands down. (Though with the new kernel that is now more or less
changed I hear). I use both, and since I try to stick to the rule "Right
tools for the right job", I'm just curious as to your choice. If it can
pump out 600+ MB/day at ftp.cdrom.com I'm sure it can handle your
situtation. :>

Yes. SMTP is not a protocol for user agents, it's for transfer agents
only, i.e. email is transferred or sent across the Internet with SMTP,
but you pick it up and download it from your mail server with POP or
IMAP. Or by mounting the mail server's mail directory via NFS. There
are bound to be other possibilities as well, but these are the ones
I've run across myself so far.
You may want to configure your Linux box to be a POP3 as well as an
SMTP server.

They should reflect the mail account that you want replies to go to.
If you have a dial-up connection, you probably want emails to appear
to come from your provider, not from the local Linux box. You could
also run into some problems, because some providers refuse to forward
email that's not coming from them, i.e. they don't relay email. This
is an anti-spam measure and if your provider follows it, email from
you which says '[EMAIL PROTECTED]' in the from header won't be
delivered.

I think so. I'm in the process of setting up sendmail on my dial-up
Linux Internet gateway, but I'm still reading the bat book, trying to
find out how to differentiate between local and Internet mail and how
to make sendmail deliver local mail immediately, but Internet mail
only periodically.. Unfortunately, I don't have the time I need to get
anywhere fast right now, too much work to do.

Use the diald package. I'm not sure if it'll work with ISDN, though,
but since I'm getting that soon, I'll have to find out as well. I
think I heard or read something about the ISDN package supporting
dial-on-demand out of the box, but I'm not sure.

more information is needed on HOW do you connect from one machine to another,
i.e. do you do telnet x.y.z.1 or telnet <name>. can you ping 3 from 2 and
viceversa, using adress and name ? are the /etc/hosts-files identical , and
what about hosts.allow and hosts.deny?

What kind of network cable are you using and was your network working prior to
this?
When you get a specific error like that it usually means what it says....there
is a problem with the network cable.
if you are using BNC cable make sure both ends are terminiated and if it is
rj-45 TP then try replacing the cable.

And it doesn't work the same way. to use M$ proxy, not only do you
have to spend $$$ on it, you also have to set up the proxy and socks
server, then you have to reconfigure all the clients the intend to use
that box at the internet gateway to connect via proxy. Then not all
your confrencing software will work as well as the ip masq of linux
with the server running the the same machine as the proxy to peer with
the actual conference chat server at another location which means that
the remote location will need configuration. That and kiss goodbye
those "advanced" connections like realaudio, games, etc.
to sum it up, NT for no amount of money can actually do IP MASQ. Only
proxy. I heard that windows 2000 server edition may include this
feature but do we really want to get stuck in the microsoft
propritarty junk. and wait another year to do what linux can do now???

To see which files Netscape opens, the strace program might help you.
See man strace. I let strace dump its information into a text file
with
strace your_command &> error.txt
With Netscape, I guess that file may become very large. But you'll
have to search for errors like ENOENT (no such file or directory) or
"permission denied".
Good luck!

The problem is with your network card. It is trying to determine the speed of
your network (10/100) and is doing so unsuccessfully. You need to tell it
explicitly, but whether thru jumpers or command line, I can't tell you without
knowing about the card.
Dhcpd won't work until there is a valid interface to work from. As a
workaround--because your card eventually recovers--you could put a sleep before
executing dhcpd.

I recently upgraded from Red Hat 4.1 to 5.2 and with this came Apache

When you shift click on the file it prompts to be saved however the file

Any ideas.....Do I have to set some special permissions for that
