Subject: Odd Modem Problem (Modem not responding) (Not a WinModem!)
Date: 3 Mar 2000 06:11:08 GMT
I've been around Linux off and on since kernel .99.15o, so believe me
when I say that this is _not_ a WinModem problem. :)
I just installed Debian "potato". Clean install, and few problems,
but I can not make this box talk to my modems. When I start minicom,
everything I type gets echoed back, but the modem doesn't respond
(other than to echo back what I type). The echoing is odd-- it
only echoes the carriage return when I hit <enter>; I can manually
type a new line, but that doesn't help. The modem doesn't act
on anything I type; e.g. typing "atdt33333" doesn't make any noise
(and should; at least the external modem I'm _sure_ is set to
make noise, since it does when hooked up to another machine, and that's
the factory default).
Just so you know I'm not crazy:
It's not an interrupt problem. The same thing happens with an
external and an internal problem, and with seterial /dev/ttyS2 irq 0
Moreover, I'm setting the interrupt by jumper.
It's not a setserial problem. If minicom isn't talking to the
right port, then nothing gets echoed back. Only when it's talking
to the right port do I even see the echoing.
I did get the external modem to talk back, by telling it to ignore
DTR. However, that caused other problems (most notably, my ppp
connection getting garbage that caused it to hang up; my ISP is
a bit draconian :)
statserial shows DTR always 1, DCD always 0. I can give more info
if necessary.
The modems are a Gateway Telepath ISA (w/ jumpers :) and a USR 28.8
Fax/Modem. The box is a gateway P5-120 that I got for $25.
Any ideas? I'm open to suggestions...
Thanks in advance,
Me

You have two posibillities to solve your problem:
1. tell fuka2 where to send packages for the subnet 192.168.20.0/24 -> fuka3
and tell fuka3 where to send packages for the subnet 192.168.10.0/0 -> fuka2
2. use default routes fuka2 <--> fuka3. this is a bit dangarus, while sending
packages for example to 1.2.3.4 ==> flip/flop between fuka2 and fuka3
Also you have to check if ipforwarding is enabled on both fuka2 and fuka3:
"cat /proc/sys/net/ipv4/ip_forward" *must* give you 1.
To enable ip_forwarding just type "echo 1 > cat /proc/sys/net/ipv4/ip_forward".
Bay the way, if you hope you will see any Client from the 10.x net in the 20.x
net => forget it! In this case you have to setup an wins server (shit!) or to
configure your linux router as ipx-routers and install the ipx network on each
windows client. This is also shit (while windows is shit) but it works :-)

Another way to get your cable modem to cache your NEW MAC address is to turn
the bugger off for a few minutes. When it is powered up again, it sniffs
around and caches the MAC address of the first NIC it finds.

This is all very interesting - Thanks Guys.
What kind of CPU/hardware overhead is required; does it slow disk access
markedly?
Is the look and feel similiar to a conventional ext2fs?
What kind of considerations are there for HD/controller type - SCSI/IDE?

Hmm, Kernighan & Pike's _UNIX programming environment_ (1984) says
: Why are there three grep programs? fgrep interprets no meta-characters,
: but can look efficiently for thousands of words in parallel (once
: initialized, its running time is independent of the number of words), and
: thus is used primarily for tasks like bibliographic searches. The size
: of typical fgrep patters is beyond the capacity of the algorithms used in
: grep and egrep. The distinction between grep and egrep is harder to
: justify. grep came much earlier, uses the regular expressions familiar
: from ed, and has tagged regular expressions and a wider set of options.
: egrep interprets more general expressions (except for tagging), and runs
: significantly faster (with speed independent of the pattern), but the
: standard version takes longer to start when the expression is
: complicated. A newer version exists that starts immediately, so egrep
: and grep could now be combined into a single pattern matching program.

Yes, most likely. Your variant will start one egrep per file found by find.
xargs will usually only run one grep but in the case of many files it will
start several greps (in sequence) to avoid the "Arg list too long" problem.
There is an alternative syntax which might look a little more
straightforward:
grep 'stringIwant' `find . -type f -name '*' -print`
But this will get "Arg list too long" if too many files match the name.

Subject: diskless root mounted nfs permission problems

I have a root mounted nfs system, 2.2.14 kernel, and the /bin /usr and
other directories are mounted read-only with no_root_squash.
I can't figure out why I can't switch user from the root account, to a
regular user. I get unable to run /bin/tcsh permission errors. Which don't
make sense because the file is set executable as 'chmod 755' and the
directories likewise the same, even the root partition '/' is NFS mounted
as 755.
Any ideas? What have I overlooked?

In addition to the progs mentioned in the other replies:
The newer gnome-applet packages come with the screenshooter applet if

1- I write a session in a cdrom with cdrecord (cdrom still open)
2- I mount the cd and i see the session OK
3- I umount the cd
4- I write another session into cdrom (cdrom still open)
5- I mount the cd and i don't see the new session, only the first...
i must open the tray an close the tray to see the new session.
I guess the TOC is not read refresh after first session, is there a way to
see the new session without open the tray ?
With a 2.0.36 kernel it work fine, but now with the new 2.2.13 kernel, i
have this problem.
