1) Ftape
I thought I'd do a backup today while studying.
Ftape seems to really misbehave with my Iomega Ditto 420
drive with approprite QIC-Wide tapes. Here are exempts
from /var/adm/messages from kernel 1.3.66 (which works
wonderfully) and 1.3.75 (were ftape is unusable)
using the same tape!. I would also like to mention,
that ftape 2.07 doesn't work on 1.3.66 either.
Somebody screwed something up between those to
releases, I guess. And since the NR_MEM_LISTS vanished
in kernel 1.3.74, ftape 2.06 doesn't even compile
with the newer kernels =(
(Ftape was compiled as module in all cases).
Here is ftape-2.06 in kernel 1.3.66:
ftape-2.06 28/01/96
(c) 1993-1995 Bas Laarhoven (bas@vimec.nl)
(c) 1995-1996 Kai Harrekilde-Petersen (khp@pip.dknet.dk)
QIC-117 driver for QIC-40/80/3010/3020 tape drives
Compiled for kernel version 1.3.66
ftape-read.c (read_header_segment) - calculated tape length is 410 ft.
.... and from here it goes WITHOUT error messages.
Here is ftape 2.08 in kernel 1.3.75
ftape-2.08 960314
(c) 1993-1995 Bas Laarhoven (bas@vimec.nl)
(c) 1995-1996 Kai Harrekilde-Petersen (khp@pip.dknet.dk)
QIC-117 driver for QIC-40/80/3010/3020 tape drives
Compiled for kernel version 1.3.75
fdc-io.c (fdc_config) - Using the standard fdc controller.
fdc-io.c (fdc_probe) - Type 8272A/765A compatible FDC found.
ftape-ctl.c (ftape_activate_drive) - drive wakeup method: Colorado.
ftape-ctl.c (ftape_get_drive_status) - error status set.
ftape-io.c (ftape_set_data_rate) - post QIC-117B drive @ 500 Kb/s.
ftape-io.c (ftape_set_data_rate) - 750 ft. QIC-80 tape.
^^^^^^^^^^^^^^^^^^^^^^^^^
This is incorrect, I am using 400ft. QIC-Wide
tapes; so this misinformation probably causes
the problems.
ecc.c (correct_block) - ECC failed (0 CRC errors, >1 CRC failures): .
ecc.c (correct_block) - attempt to correct data at 255.
ftape-read.c (correct_and_copy) - ecc failure on segment 0.
ftape-read.c (read_segment) - ecc failed, retry.
ftape-read.c (read_segment) - interrupted by non-blockable signal.
ftape-read.c (read_header_segment) - header segment damaged, trying backup.
ftape-read.c (read_segment) - interrupted by non-blockable signal.
ftape-read.c (read_header_segment) - no readable header segment found.
2) PPP
With 1.3.75 the PPP protocol behaves quite odd. File transfers
either take forever, or abort prematurely. I also have trouble connecting.
Also, Netscape 2.0 gives those "Connection Reset by Peer" messages
again. This might be buggy Netscape, but I didn't get those in .66.
Again, here are exempts from /var/adm/messages:
Here is 1.3.75:
Jun 18 15:01:08 (none) chat[420]: send (PPP^M)
Jun 18 15:01:09 (none) pppd[418]: Serial connection established.
Jun 18 15:01:10 (none) pppd[418]: Using interface ppp0
Jun 18 15:01:10 (none) pppd[418]: Connect: ppp0 <--> /dev/cua1
Jun 18 15:01:28 (none) pppd[418]: Modem hangup
Jun 18 15:01:28 (none) pppd[418]: Connection terminated.
Jun 18 15:01:28 (none) pppd[418]: Exit.
Notice that after the connect, PPP never actually
establishes a connection, but rather dies.
Look at 1.3.66 for a change:
Jun 18 15:11:37 (none) chat[248]: send (PPP^M)
Jun 18 15:11:37 (none) pppd[246]: Serial connection established.
Jun 18 15:11:38 (none) pppd[246]: Using interface ppp0
Jun 18 15:11:38 (none) pppd[246]: Connect: ppp0 <--> /dev/cua1
Jun 18 15:11:39 (none) pppd[246]: local IP address 205.240.87.95
Jun 18 15:11:39 (none) pppd[246]: remote IP address 204.214.4.7
Here in 1.3.66, everything works fine and ppp establishes
a connection. I believe it's not my providers fault, I
tried this several times, and it can be reproduced =(
What a big message I've produced -- I guess I'll go back to what
I'm supposed to do - study ;)
Cheers,
Jochen
P.S. The new kernels are really cooooool. Go Linus! =)
