Linux supports this printer very well. My old Laserjet III has been
running with Linux for two years, no problem. Linux uses a piece of
software called Ghostscript to turn Postscript output into PCL
commands that the Laserjet understands. Try using apsfilter to set
things up for you and all will be well.

Absolutely... 2.30 is a FAR better distro than 1.30... In fact, the just
released last month eDesktop 2.40 is even better than 2.30. You can grab a copy

It all worked perfectly. Since that time has passed... I'm now running 2.40
and it's lightyears more "pleasing" than 1.30 ever hoped to be... :')

Well... it's ipmasq ( kernel 2.0.36 from LRP). And no, port
16000 is not closed on the firewall... otherwise there's no way I
could EVER connect to the inside sshd. But I can; under a certain
set of conditions ( when I'm ssh'ing out of my in-host to out-host
and then ssh'ing from the out-host back to in-host).
But I can't connect while attempting a direct ssh connection from the
outside ( i.e. when I'm physically located outside the home ) That's
the weird part.

Well.. no. The internal machine is not firewalled. There's no such
problem. So any other possibilities ?

When I try to launch an X app via an xterm, I get a messsage:
can't open screen or connect to a TransSocket. Some other
terminals will do it. I think rxvt in Redhat 5.1. In Redhat 6.1
I can launch the apps via doing Start | Run and then type in
the app to launch.
Why can't X apps be launched from any terminal screen. What
are the issues.

Date: Sun, 30 Apr 2000 17:15:26 GMT
Okay, I'm a semi-newbie. I've run Linux for about 3 months on dial-up
and now got ADSL so I'm reconfiguring for some specific things.
First, I downlaoded RH 6.2 and installed fresh (had screwed up my
partition sizes last time) and got it working.
Next, I downloaded 2.3.99 PRE 6 and configured. Compiled okay... set
up LILO to select from my old or new kernel (thank goodness!)
When I boot 2.3.99 I get "HD: unable to get major 3 for hard disk". I
thought at first I had neglected to compile in an IDE driver, so I
recompiled with all optional IDE and HD drivers to no avail.
My hardware specs are as follows:
486 120 Mhz
VLB ide card
two small hard drives - 602MB and 327MB
2x CD-ROM (disconnected it once to see if it was the problem)
Two NE network cards (works fine)
WD VLB video card
I don't know where else to look for the problem. It will still boot
my old kernel fine which is a stock RH 6.2.

Will blow up most of your mail aliases. Will mess up some group-based
permission schemes on some systems. Will completely hose pam-based
console owensership handling. Will break /etc/crontab on many
systems. Will break large numbers of inetd run processes. May break
older applications that expect to find an entry for root. Other than
that, side effects may be light. ;)
If you _really_ want to do this, there are definately better
ways. However, it's difficult to suggest anything without knowing
exactly why you want to change it.

Anyone out there know why linux's ps command chops off its output if you
send it through a pipe? ps's output stops at 80 characters per line
when sent through a pipe, making greping for processes with long names
impossible. Using ps with pagers is also pretty useless. Any ideas?

I had a similar problem. If you look at the messages log, the box that
sshd is running on is probably complaining about attempting to connect
from a privilaged port. For me the problem was solved with the -P
option to ssh:
ssh -P -l mylogin myserver.abc123.com
which forces ssh to use non-privaledged port. This will help in
masquerading situations where port numbers are not always the ones that
client applications open (in fact they almost never are.)

Subject: X locks up solid, what can I do ?! HELP !!!
Date: Sun, 30 Apr 2000 13:42:35 -0400
Greetings:
First, apologies for the cross-post, but I believe it was necessary.
Periodically, while on the network (PPP connection to my ISP), X will
lock my machine solid, requiring a complete power down to get it running
again. Here's the situation:
This problem has accurred sporadically for the past year or so. It
happens irregularly, and /var/log/messages reports this right before the
freeze:
Apr 29 15:44:04 localhost modprobe: can't locate module char-major-108
Apr 29 15:44:04 localhost pppd[5601]: pppd 2.3.10 started by root, uid 0
Apr 29 15:44:04 localhost pppd[5601]: Using interface ppp0
Apr 29 15:44:04 localhost pppd[5601]: Connect: ppp0 <--> /dev/ttyS3
Apr 29 15:44:13 localhost kernel: PPP BSD Compression module registered
Apr 29 15:44:13 localhost kernel: PPP Deflate Compression module
registered
Apr 29 15:44:13 localhost pppd[5601]: local IP address 209.143.26.110
Apr 29 15:44:13 localhost pppd[5601]: remote IP address 209.143.26.103
Apr 29 15:44:14 localhost modprobe: no dependency information for
module: "/d
ev/ttyS3"
Then the crash happens.
I'm using a USR 56K internal modem, it's not a PnP card or a
Winmodem. This lockup has occurred through at least two separate
installations, so I strongly suspect the modem, but I have no idea what
I can do to eradicate the problem. The modem is set to use IRQ3. There
are no apparent conflicts.
I have been told that this will happen when running X as root (I'm
not), or when running Netscape (almost always happens then, but not
always). My machine is a 550 PIII with 256 MB RAM. I also have a SB
PCI128 soundcard installed and use the commercial 4Front drivers. Video
card is an ATI 8 MB Xpert@Play (AGP).
Please let me know (via email as well as on the newsgroup) if more
details are required. I would dearly love to resolve this once and for
all. Any serious advice will be *vastly* appreciated !!!
