Subject: 1.1.24 & Slackware BUG???
Date: 1 Jul 94 03:52:37 GMT



     I've just come across a VERY VERY weird problem with the
new 1.1.24 kernel, and possibly earlier 1.1.xx kernels. It has
to do with the 'pkgtool' program in Slackware 1.2.0.x. 

Problem: 
        When I run pkgtool and choose remove packages from the
menu, a list of all installed packages comes up. Well here's the weird
thing: While moving the cursor with the up and down keys to select packages
to remove, the program crashes and exits!! The up and down keys, which
work normally anywhere else, seem to send weird characters in remove section
of pkgtool. If you have a new kernel and Slackware 1.2.0.x, please try this
and let me know if it happens to you too. Scroll up and down a few times
in the remove part of pkgtool and see if the program crashes.

Please try this at home !

Thanks,

Subject: List of programs which need shadow changes
Date: Sun, 3 Jul 1994 02:05:14 GMT

I am trying to compile a list of the programs which must be changed,
or have changes, to support the shadow password suite. The following
are the programs which I know. Does anyone know of others?

I am looking for those programs which need to access the password
field to do account validation. Programs such as "ls" do not need the
password and do not need to be changed.

The passwd program is included in the shadow suite. It is a new program
and, by definition, does not need changes. It is replaced.

telnetd
ftpd     { both the bsd and wu versions }
pop2d

Subject: 1.1.24 != Sound.
Date: 3 Jul 1994 05:23:42 GMT

  Since the upgrade from 1.1.13 to 1.1.24, my sound driver has been on
the fritz. The card is an antique Sound Blaster 1.5 with the standard
settings. Audio files piped to /dev/audio (or from) attempt to play
for about a second, and then die with a DMA error.

  Found in syslog after two attempts....

Jul  2 23:43:25 orbit kernel: Sound: DMA timed out - IRQ/DRQ config error?
Jul  2 23:43:48 orbit kernel: Sound: DMA timed out - IRQ/DRQ config error?
Jul  2 23:44:50 orbit kernel: master pty_close: count = 3!!
Jul  2 23:44:50 orbit kernel: master pty_close: count = 2!!

  The master pty_close messages have only appeard those two times, and
never again. (And never before). Probably not related, but...

  I've checked twice, and I didn't set an IRQ or something wrong. When
I set up the sound driver, everything is disabled except for
SoundBlaster and digitized voice. Early drivers caused my kernel to
panic, but since 0.99(pl ?10?) everything has been very reliable.

  Has anyone else had the same problem? Have any idea how to fix it,
except step back to an earlier version?

Yes and it works well. If you have a kernel > 1.1.19 i think there
is a patch for cdu33a so it works with double-speed and dma !!

( 386DX40-8MB = ~ 280KB/s )

But before you install it to the Kernel look into the source if
the baseadresss and DMA-IRQ is right !

Have you ever been able to run two jobs at the same time on a DOS box? :-)

Anyway, if you try this you will see that it basically works.  There is no
problem at all when you exit the programs on a last-in first-out basis.

It is not amazing at all that it does not affect IDE systems.
Remember, the original post was about a SCSI system, which is an entirely
different thing.

Remember, on your IDE system the two drives share a single controller
(on the master drive), so adding drives will not at all increase the
throughput.  This leaves only the effect of seek locality.

i have three Linux machines on a network, along with ten machines running
Workgroups for Windows with PC-NFS. It does work most of the time, but
every now and again the PC-NFS server decides not to talk to anybody
any more. It is 'pingable', and can telnet, ftp etc to other machines,
but it will not accept any connections. I get strange messages in my
'syslog' and 'messages' file about connection timeouts and missed interuppts

The network is in a star configuration using a 3com hub. Does anyone have
any thoughts on why this is occurring?

Any help would be most appreciated!!

The Philips CD-R *IS* a recordable cd-rom player/recorder.

So the question still stands, is there a driver for Linux to support the
Philips CDD521?

And if there is, what is the likely hood of under-buffer runs?  Recordabl

CD's are very particular about continuous data flow.

Small brain damage on my side... Partly initialized static structs
have their noninitialized fields set to 0, so as long as all drivers are

some rlogind's which don't pass off authentication to login

can't think of any others off the top of my head.

Subject: g++2.5.8 strange bug
Date: 1 Jul 1994 16:45:30 GMT

Greetings all,

        I believe I have found a pretty serious bug in 2.5.8 of GNU C++, 
at least as far as using it under Linux 1.0.8.

        The following program (though very fundamental and straightforward) 
will, when run, cause a segmentation fault:

// ------

#include <iostream.h>

class  A
{
  int i;
public:
  A() { cout << "creating A\n"; }
};

main()
{
  A* p = new A;
}

// ---- 

Any ideas?

Well consider this: If Linux and DOSEMU share the same Enet card for TCPIP
then essentially you're putting a network in a single box. Mui confusing
if you have the same IP for both.

Since the Linux kernel already handles routing, maybe it can easily be done
by doing a few things:

- Giving the DOS entries their own net IP (not loopback).
- Using a copy of the loopback interface to connect DOSEMU sessions. 
- Using the now working route interface in the kernel to route packets
  to the DOSEMU loopback interface.

Note that the standard loopback (127.0.0.X) is not the same as the DOSEMU
loopback which should be assigned a real net address.

That way DOSEMU sessions connect to the DOSEMU lookback interface, the Linux
router routes packets for the DOSEMU net to that interface. End of problem yes?

BTW I have no clue how to code this. I'm just an idea guy here.
