FC3 and ghostscript
by Bill R. Williams
I went straight from FC1 to FC3 and something ugly has appeared.
(I mention this because it might have appeared in FC2, but I wouldn't
know.
The ghostscript output UGLY! Big clunky-looking font.
Easy to create example: (using yum startup -- any [ba]sh script will do.)
$ enscript -p out.ps -G -C --color --pretty-print=sh /etc/init.d/yum
$ gv out.ps # or whatever GS viewer you use
The above example you can do a perl script (--pretty-print=perl) or
whatever.
Part of the problem is easy to notice that because there is COLOR in
out.ps the gv display will have some text "backed-up" over preceding
characters. Not so noticeable for those who don't do a lot of
'enscript' of scripts, is that the font is big and clunky and runs off
the right-hand side of the "page".
I do quite a bit of programming in various scripts and sometimes
C/C++, and I have a need to produce nice program listings.
I have used 'enscript' for years; from RH v7.x through FC1 it produced
exactly what I needed. With FC3, it is just unusable for my purposes.
Note that NO FONT is specified, so I am used to getting the default
which is mono-spaced resulting in output that has all characters lined
up as they should be. (No variable-width character adjustment.
Kerning?) I have tried many variations specifying a font to get back
to what I want. If I specify something which produces variable-width
characters, the output is "correct" in that there is no "backed-up"
text due to the color specification; however, this type of font is no
good for program listing purposes.
I have determined that the problem is with ghostscript! (Any utility
I use which displays postscript uses ghostscript.) I can produce my
standard enscript output on my FC3 system at home, take it to my
office and look at it on my RH 7.3 system with gv and it is as I want
it to be.
This problem is significant to me for several reasons, and affects my
intention to upgrade my system at work to FC3.
Help will REALLY be appreciated!
(Including the proper "official" place to post this.)

CUPS: howto avoid that CUPS disable LPD printer
by Dario Lesca
If I send a job to a LPD printer (lpd://printServ/port1) and if the
printer is off, after a lot of minutes CUPS disable the printer.
When I turn on the printer CUPS not re-enabled it and I must run as
root /usr/bin/enabled printname or use http://localhost:631/printers
Is possible to avoid the "disable feature" :-( ?
Or I want install a cron job witch every 5 minutes check if the printer
is disabled and re-enabled it?
Many thanks.

dual-net problem
by Terry Horsnell
Hi all,
I have a system with dual gigabit ethernet ports.
I've assigned them each an ip address, and am using
tcpdump and ping to check that they work as expected.
They dont.
If I ping, from another box, the address associated with eth1,
the traffic appears on eth0. This only happens when I ping from
another Linux box - if I ping from one of my Alpha boxes, everything
works as expected, i.e. pings addressed to the ipaddress
allocated to eth0 appear on eth0, and pings to the ipaddress
allocated to eth1 appear on eth1.
I'm running FC3 with kernel 2.6.10 on the dual-eth box, and I've
tried pinging from RH7.3, RH9 and FC3 boxes, all with the same
result.
It appears from the tcpdump output below, that ls1 is returing the
mac address of the eth1 interface *and* the address of the eth0
interface. Is this proper? What am I doing wrong?
Cheers,
Terry.
e.g.:
FC3 ping source:
[root@dev1 ~]# arp -d ls1
[root@dev1 ~]# arp -d ls1-2

Did this help?
FWIW, I now have an FC3 package of the new BitTorrent 4.0.0 client (no
longer a beta) at:

Tape backup software recommendations
by Gérard Milmeister
I am looking for backup software for DDS tapes. Apart from tar, star,
cpio and their relatives I found taper (taper.sourceforge.net), which
seems perfect for my needs (single system backup). However this software
hasn't had an update for over 2 years, and since it uses a non-standard
(i.e., non-tar, non-cpio) format for its backup, it is uncertain that
backups will be retrievable in the mid to far future. Suggestions for
current solutions similar to taper would be welcome.

create a restricted user
by Zacharie Elcor
I want to create a restricted user without password that can only use
a web browser.
I added a user named "visitor" and created in his home dir a file
.xsession that contains:
firefox
so that when he logs in, firefox is launched, and when he closes
firefox, he is logged out.
This works fine but he is still able to ctrl+alt+F(1-6) and log in to
browse the file system.
To prevent that, I tried to set /bin/false as the default shell for
that user in /etc/passwd but this also prevented him to log in
graphically.
Is there a way to be sure that "visitor" will only be able to browse
the web and not the file system ? any security issues ?
Thanks for help
