If you look in /usr/include/socketbits.h down where you
see the list of PF_* stuff, you'll see that 3 and 6 refer
to AX.25 and Netrom, neither of which you are likely to have.

Are you sure this is the cause? It's not that standard
Redhat bug which makes it so that your hostname resolves
to 127.0.0.1, causing sendmail to wait around 3 minutes
while booting?
Wait longer or boot off a floppy or cd and check your
/etc/hosts. Make sure that your hostname is not on the
same line as 127.0.0.1
Hope this helps

I've just got an opportunity of installing RH 6.0 yesterday, took quite a while
for me to figure out some of the stuff inside RH 6.0 since some configuration
files have changed. And guess what, /dev/ttyS* are all rw for root only and not
for the others, and pppd is not setuid root. Good for a secured environment, but
for us who're running Linux in our spare time, this can be a disaster.. finding
what went wrong.. RH 6.0 also has /dev/cua* which made obsolute by kernel 2.2.X
and this made my /dev/modem to be linked to /dev/cua* by pcmcia script file. I
need to delete the /dev/cua* to get it working (tho' I can surely edit the
script.. but since /dev/cua* are no longer needed, deleting them won't harm).
Anyway, moral of the story, the standard installation sometime doesn't work for
you, you still need to read the HOWTOs and READMEs and need to manually tweak
your system.

My system is set up to work with _several_ of these services. I personally
telnet and ftp to my machine from work. Imap is mail and pop3 is mail...
which of these do I need for sendmail to send and receive mail (both internet

Unfortunately, the way the GUI draws widgets is determined by the widget
set used by the PROGRAMMER of an application. You can't normally change
that yourself, and it'll vary from program to program. A few widget sets,
such as GTK, do let the user choose from among several different "looks"
for widgets, however, so if you want to choose an application based on the
widget set it uses, and/or if you want to program your own applications,
all is not lost.

I was completely unable to make ppp work with a 2.2.1 kernel, configured
identically to my 2.0.34 (35?) kernel, in which ppp works just peachy.
The 2.2.1 kernel was downloaded; the 2.0.34 kernel and the
rest of the system was as-distributed SuSE 5.3.
So, I've backed off to 2.0.34 until this is resolved.

Oh, you mean such that other users, who don't want that color trash, have to

Really a great idea.
Is there a specific reason why you didn't put it into your private

I'm sure theres a way, and it could probably be done with a little trial

Anybody have any good examples of using pptp for linux ??
I would like to know if its possible to use pptp on linux to connect to
a network that is using ms-chap, and secureid authentication ?? Right
now I have to use an NT workstation : and the setup requires :
1) ppp connection to local ISP.
2) an nt user account/password for an NT domain to connect too at the
other end of the pptp connection..
3) secureid username / password..
Any ideas ??

Linux is Linux, no matter what distribution it be (ie. RedHat,
Caldera, Debian, SuSE, etc.) As for book, there are a lot of good quality
books out there, some better than others. I can't really make a pick out
of any of them since none are perfect. What I can do is tell you which
ones to avoid. The IDG one's (ie. ... for Dummies) Linux books completely
suck, IMO.

Subject: Odd Kernel panic
Date: Tue, 25 May 1999 02:43:21 -0400
I am having this small, but annoying problem, with Redhat 6.0 on a Dell
Inspiron 3200 (dual boot linux/win98).
If I allow LILO to time out and automatically launch linux I get the
following error:
VFS: Cannot open root device 00:30
Kernel Panic: VFS: Unable to mount root fs on 00:30
If I just hit enter at the LILO prompt to start linux everything works as it
should.
This happened first with the 2.2.5 kernel from the redhat cd. I compiled
and installed the 2.2.9 kernel and am having the same problem. I've ran
both
Slakware and SuSE on this machine without any problems.
Any help would be appreciated

This creates a stub. You must uncomment only the settings that work for

Then you run isapnp:
isapnp /etc/isapnp.conf
