Got *THAT* right. I've done Slack, 2 different versions of RH, and just
picked up SuSe 6.1 yesterday to install on a virgin hd.

But a bit bloated on install...
I threw it on, & it chewed up 1.9 gigs of footprint. KDE looks nice
(first time I'd ever seen it, btw...), but I'm having problems getting ppp
working right. For one thing, where does SuSe stash my *mail*???? It
sure ain't /var/pool/mail, unless I screwed something up...

The SuSe reconfig tools seem ok... But then, I've been using Linux for

They're spread out over 5 cd's. *sigh* For my *base* install, I tried
putting a 100 meg / partition and got told that I had too much to install
there by about 40 megs. Didn't *have* that problem with Red Hat. So, I
ended up putting my swap as the first partition, then the rest of the
drive for the Linux filesystem. Crude, but it works...

RH 3.0.3 & 4.1 with some tarballs added, and an *OLD* Slack, can't even
remember *which* version now.

My two bitches? SuSe spreads all the rpms all over 5 CDs, *AND* doesn't
put version numbers on the rpm filename. Course, I'm kinda used to the
way RH does things...

Subject: RH 6.0: pam_rhosts_auth -> rlogind: Out of ptys
Date: Sun, 30 May 1999 16:34:17 GMT
RH 6.0 has some really nifty security features, which prevent me from
logging into my machine from a remote site.
The remote user gets
rlogind: Out of ptys
or elnetd: All network ports in use
but the /var/log/message log tells me
linux pam_rhosts_auth[#]: denied to username@remotemachine for user
localuser
How come the messages from pam are so informative in telling me the
reason why a user has been denied? (E.g., denied because user "xyz"
does not appear in file /etc/somewhere.dot.)
Now, I know about /etc/hosts.allow, and I do not think this is it.
Could anyone please enlighten me?
Sincerely,
/ivo welch

I'm having problems with the stair-stepping text effect when
printing ascii text files from SuSE 6.1. With RedHat they have
the printtool program that allows for correction. Does SuSE
have another printer setup tool other than the one that comes
with YAST that allows for correcting this problem? I'm sure it's an entry
in the /etc/printcap file but in the past when I've edited this file
directly , lpd stops working all together.

Simplist Approach:
==================
If you take a look at /etc/fstab, you will
see that each file system has a option field,
which you will probably only see "rw" and "ro" for now.
Just add ",async" to it, so that it reads "rw,async"
Then when BSD boots again, it would add the async flag.
Do It Without Reboot:
=====================
Say I want to set my "/usr" system to "async", just do
mount -u -o async /usr
(If you want this to be the default from now on,
then you still need to make the changes to /etc/fstab)
Explanations:
=============
Without "async", then many changes (including directory info change)
would be written to disk immediately. This way, it is slower
but reliable. (If power failed, then it's less likely that
your file system would end up inconsistent.) With "async",
then many changes are buffered.
This is what the others mean by "FreeBSD default is safer
though slower".
Given what I understand, Linux mounts with async by default,
and thus is "faster though less safe".
"SoftUpdate" !!!
================
Note! FreeBSD now has a new "SoftUpdate" technology,
which offers equal/faster performance than async
and yet offers equal/better integrity!
As far as I understand, some people believe the "SoftUpdate"
is not yet fully tested, and so I have not used it myself.
But keep your eyes open for news regarding SoftUpdate!
(I understand there is similar new technology
in the Linux camp as well.)
Other Flags of Interest
=======================
You may also want to add "noatime" flag.
By default, accessing a file wopuld cuase the access time
to be logged.
If you set "noatime", then only "modifying a file" would be logged.
PRO for noatime:
--> When you're justing reading the files, then no
disk write occurs. So much faster.
CON for noatime:
--> With noatime you would not know if someone had read your files.
And so for certain high-security file systems,
you probably want "atime".

Look in the front of the SuSe book that came with the cd's. It's right
there on the registration cards.

hi.
I'm using emacs 20.3.1 from slackware 3.6 packages and I have some questions.
1. How do I do syntax highlighting on c mode?
2. How do I scroll just 1 line when I press CTRL+n on last line of screen?
3. What's the command to go back to previous position after long jump?
thanks.

It's perfectly reasonable so to do. An ISP is selling derived value,
on the basis of licencing access to network infrastructure at a given
price for given terms. On a commercial basis the ISP decides to deliver
certain products to market in certain price brackets. It's entirely
within their rights to specify that the customer does not then undermine
that price structure (and quite possibly the viability of the services)
by using the facilities of a cheaper product to avail themselves of the
functionality of a more expensive one. (If you as the client don't
like what the ISP wants to selll you, go to another...) Naturally
the things the ISP can't do are specify illegal restrictions
(however local law may determine that), or specify restrictions that
would be unenforcible outside of illegal behaviour. In the UK that
would mean that the ISP would need to gain, as one of its contractual
terms, the right to port-scan or whatever other measures are necessary.
