Huh,
I use netscape (4.5) under linux. When I click on a mailto-tag, netscape
close itself automatically. Why?
(It was funny when I downloaded 35M from an 42M file)
What is the solution?
- Don't click on it?
- Patch it?
- Change it to iexplorer? (sorry, dumb joke :-)
- What else?
thank U for assistance.

Date: Wed, 21 Jul 1999 13:20:44 +0200
Can someone help me for the following problems?
1 GIVEN: Under X the program minicom works very good; but in a normal
textconsole the program minicom doesn't work:
# minicom //textconsole
minicom WARNING: configuration file not found, using defaults
DEVICE /dev/modem is locked
QUESTION: how can I unlock the device /dev/modem ? The symbolic link to the
device /dev/modem is of course OK. Ik have a dynalink V1433VQE modem.
2 # ifconfig ppp0 is in order (all values except MTU (=1500) �n Metric
(=1) are 0, but the de interface is not yet "up")
#ifconfig ppp0 up
SIOCSIFFLAGS: device not configured
QUESTION: how can I configure this ppp0 interface , knowing that this
device by netcfg (X)(cfr. http://users.skynet.be/jmi/netcfg is configured
and that the automatic made script /etc/sysconfig/network-scripts/chat-ppp0
seems to be completely OK)
3 GIVEN: if I "ACTIVATE" with netcfg (X) in the tabpage interfaces the
interface ppp0 , then after saving, each time she is automatic desactivated?
QUESTION: how can I KEEP the interface ppp0 ACTIVE ?
4 GIVEN: Netscape doesn't recognize my hosts (there is for instance not an
entry to home.netscape.com)
QUESTION: what am I suppose to do that Netscape should recognize my
hosts and that the server could localise home.netscape.com ?
5 GIVEN: telnet pop.skynet.be 110
QPOP (version 2.4b2) at foxbert starting
user ........
pass ..........
QUESTION: which is the "help"-commando that I can use for finding what are
the command's that the mailpakket QPOP (version 2.4b2) is using? Can I find
in the Internet a helpfile (http://......) for the mailpacket QPOP (version
2.4b2) that is describing that the commands?
I hope really that someone can help me:

Subject: ppp0 and eth0 ip address problem
Date: Wed, 21 Jul 1999 10:24:04 GMT
when dialing in on a NT RAS Server I have the problem that the local
address it gives me for the ppp0 device is the eth0 address.I call in
on a nt RAS server.
This works according to /var/log/messages
Jul 20 12:13:53 mobajs1 pppd[746]: local IP address 194.171.168.107
Jul 20 12:13:53 mobajs1 pppd[746]: remote IP address 192.168.1.130
The strange thing is that ppp gives me the eth0 ip address as local.
When I call in from WINNT it does work, but I want to get rid of WINNT
I dial with pppd. I use pppd call sol0. Here is my sol0 script:

ping 192.168.1.1 does not work as also all other ip addresses in this
net.
this all is very weird to me. What's happening? shouldn't the ppp0-local
address be something else? It is when dialing in with NT.
Can somebody help me with this?

Greetings all,
Recently, I've started getting error messages during my boot
process. They are:
Module redhatppp does not exist
Module inittab does not exist
I think they came about when I installed some later version of linuxconf
and then reinstalled the one from the Redhat5.2 CD.
Any help in fixing this problem would be greatly appreciated.
Thanks!

What Lew said. You see, Carlos, your "client" machine is sending out
packets that say "these packets should come back to 192.168.0.2" -- but
when they arrive anywhere outside your own LAN, the recipient says "Oh,
those are local, non-routable, do-not-put-onto-the-Internet packets." And
promptly drops them on the floor. Which is GOOD. You don't want your
local LAN trafffic running around the Internet. You did the right thing in
assigning your local LAN addresses the way you did.
IP Masquerade will translate those local addresses on the way out of
the machine that has an Internet connection, so when they arrive at the
remote site, they will have a return address that points back to your DSL
connection (I'm jealous! Want one!). That machine will in turn change the
address back to 192.168.0.2 and send it out the other NIC to the machine
they originally came from.
It's very important that you use only Internet addresses that have been
assigned to you; otherwise your traffic will get hopelessly lost (and
whoever owns the random address you picked out of a hat will come looking
for you with a baseball bat, if not a warrant.)

I didn't understand the question, so I guess some others
didn't either !
What do you mean by "splitting " a TCP connection ?
TCP is not a wire !
And what is a "network emulator" ? Do you mean hub ?

Hello,
Interface eth0 cannot start on my machine which uses AMD 79C970 Ethernet
controller, because this controller is implemented on the same board as
the SCSI controller, so that the two devices share the same IRQ number.
Does someone know if there is a later release of the Linux kernel which
supports this paticularity and where I can find it ? The current version
of my RedHat 6.0 kernel is 2.2.5.

We are running a Linux file server serving Macs, Windows
95/98 and of course Linux. We us Samba for the Windows part
and Netatalk for the Mac part.
Samba is relatively easy to configure, there is a nice tool
called SWAT that makes it possible to set it up via a
web browser interface. If you dont have any Linux/Unix
experience, it wont be a one day thing, but I guess thats
also true for NT.
Stability is as good as it can be with Linux, i.e., the
only reboots necessary are when I upgrade the kernel. We
have the server runnning for about half a year now.
Someone else mentioned that you might want to migrate
gradually from NT to Linux.
Give it a try, you will love it.
Good luck (though you wont need good luck wit hLinux,
itworks without it)

Lee,
By default, most distro's of linux disable sendmail from being what is
called an "open relay". This is a good thing, considering that >50% of all
email servers on the internet still allow relaying. This is how the spammers
of the world send their trash to your inbox. They simply use your email
server (as a relay) to send thier S@%T.
To fix the problem you described, you will need to edit one or more of the
following files to allow your clients and/or network address (i.e.
192.168.0.0/24) to "relay" email off of your server. I'm going from memory
on RH5.2, but most of the files in /etc/mail directory have some comments
within describing their purpose in life.
/etc/mail/access (RH6.0)
/etc/mail/ip_allow (RH5.2)
/etc/mail/name_allow (RH5.2)
This should get you headed in the right direction
