I've got linux (Slackware2.0) recently installed on a 468-66. It has an
|
|
ethernet card and is networked to Novell and and UNIX. When ftp/telnetting
|
|
from linux to elsewhere things generally work well. However, when trying to
|
|
ftp into the linux machine (most notably from the novell network) the
|
|
session frequently freezes. Pressing cntl-C returns the ftp prompt, but the
|
|
last action ends up being truncated. A good example of this is a file
|
|
transfer. All packet but the last one get through. Then it freezes and the
|
|
last packet it lost.
|
|
|
|
Does anyone have any idea what is going on here?

I've got a tape Shuttle that runs DOSARCH on MS-DOS machines to back up
|
|
data. I'd like to use it to back up data from linux as well. The tape
|
|
shuttle is simply called "tape shuttle 525" and it has both SCSI III and
|
|
parallel connectors. The parallel connector is generally used with DOS
|
|
machines, and since my linux machine doesn't have a SCSI port I'd like to
|
|
use the parallel port.
|
|
Is there any way I can use this to back up data from linux?
|
|
If possible I'd like to use the same format (?) as Dosarch does on MS-DOS.

This misunderstanding probably comes from the fact that sendmail DEBUG
|
|
mode allowed remote execution of commands (worm etc) but smail's debug
|
|
mode simply allows to to specify the verbosity of it's commentry on
|
|
what it is doing. I've pretty carfully checked through the smail
|
|
source and can't see anywhere where having the DEBUG on causes any
|
|
problems.

Hi Folks,
|
|
|
|
I'm having a tough time setting up 'term'. When I run linecheck,
|
|
I get the following output (stderr) on the local and remote machines:
|
|
|
|
Local machine Remote machine
|
|
============= ==============
|
|
Handshaking Handshaking
|
|
Handshaking sucessful
|
|
0 sending char
|
|
|
|
After that, both linechecks hang. I start the remote linecheck as:
|
|
|
|
$ linecheck 2> /tmp/linecheck.remote
|
|
|
|
and the local linecheck as:
|
|
|
|
$ linecheck < /dev/modem > /dev/modem 2> /tmp/linecheck.local
|
|
|
|
When the remote linecheck first starts, it spits out an 'A' on the screen.
|
|
As soon as the local linecheck starts up, the remote linecheck spits out:
|
|
|
|
|
|
B
|
|
|
|
0 ABC
|
|
|
|
on the screen.
|
|
|
|
The problem seems to lie with the remote machine. Both remote and
|
|
local machines are PCs running Linux. If I make a connection to a remote
|
|
machine running Ultrix (via the same route) everything works fine.
|
|
A similar problem seems to afflict file transfers via 'sz' from the remote
|
|
system. In this case the locally-running 'rz' creates a new, zero-length
|
|
file then hangs, waiting for data. As with term, the problem goes away
|
|
when the remote host is a DECstation running Ultrix.
|
|
|
|
Here's a description of the local and remote systems:
|
|
|
|
Gateway 4DX2-66V
|
|
Linux 1.0, 1.09 or 1.50 (same results with all)
|
|
Term 1.08
|
|
'setserial -a /dev/modem' yields:
|
|
/dev/modem, Line 1, UART: 16550A, Port: 0x02f8, IRQ: 3
|
|
Baud_base: 115200, close_delay: 50, divisor: 0
|
|
Flags: spd_normal skip_test
|
|
Same reults with a 14.4 kilobaud internal modem and a 2400 baud external modem.
|
|
Seyon 2.14b or minicom 1.5beta (same results with both)
|
|
Connection to the remote machine is made via a dial-in line connected to a
|
|
Cisco terminal server.
|
|
|
|
Does anyone have any suggestions?
|
|
|
|
Thanks in advance,
|
|
Bryan

nothing would appear on screen until I typed the last 't', and then the whole

That's certainly a provincial attitude to take about it. I, on the other
|
|
hand, have heard plenty about it, almost all inferior. The system is not
|
|
standard enough to port 1/10th of the stuff we love Linux for, according to
|
|
those I have heard from. So if you want a nearly-real-time fast unix that is
|
|
too nonstandard to use any but the vendor-supplied tools on, feel free but
|
|
don't come here for sympathy.
|
|
|
|
I stand ready to accept flames since I too have not actually used QNX, but
|
|
only accepted second-hand info on this.

Have you considered using the X Display Manager (xdm)?
|
|
|
|
Xdm provides services similar to those provided by init, getty
|
|
and login on character terminals: prompting for login name
|
|
and password, authenticating the user, and running a session.
|
|
|
|
To start a xdm session simple type "xdm" at your command prompt.

Last Sunday evening I made console resizing as an application
|
|
of dynamic virtual console allocation. Hope to put kbd-0.88
|
|
on funet tomorrow or so.
|
|
It works like this: (i) get svgalib, compile and put the program
|
|
restoretextmode in your path. (ii) get (by whatever means, e.g.
|
|
by rebooting linux with vga=ask in the lilo config file, or by
|
|
using something under dosemu) the console video in the desired
|
|
state(s), and say "restoretextmode -w file" to store the state
|
|
of the video hardware. (iii) After this preparation you can at
|
|
any moment change the console size by saying something like
|
|
"resize 50x80". The program resize will reallocate console
|
|
screen memory for all virtual consoles, send a SIGWINCH to
|
|
all programs involved, call "restoretextmode -r file" to set
|
|
the video hardware, and call "setfont font" to get reasonable
|
|
characters. For me it works beautifully.
|
|
|
|
So, it seems that this replaces the question "Can I get 50x80
|
|
text mode under Linux?" by "Can I get the video hardware into
|
|
50x80 text mode?".

We have had lots of problems with the Sliplogin program here: When a user
|
|
disconnected, in some situations the program would not kill itself. The fault
|
|
is in the: close() function, which does sometimes not return. I have tried up
|
|
to kernel 1.1.50. I have written a patch in the source of sliplogin, which
|
|
kills the program after 15 seconds, if close(0) does not return. However,
|
|
this must be a Kernel problem.

Bart.
