Subject: accidentally changed permissions of /var - *nothing* works!
Date: 21 Oct 2000 17:55:47 -0400
I ran chmod -R 755 . from the wrong xterm (as root, naturally) and
screwed up:
man pages
lpd/lprng (I've reinstalled both but can't get either to work anymore)
exim/procmail
probably syslogd, but haven't seen signs of it yet.
I'm running debian, so, after comparing permissions to match my laptop
(which didn't work), I just purged and reinstalled the following:
lprng, magicfilter, exim, anacron, at, biff, cron, logrotate,
metamail, procmail and procmail-lib, mailx, nmh.
I thought that would fix everything, since /var was just about empty,
but when fetchmail tried to place things in my spool/mail directory,
it failed.
I got man to work by changing /var/cache to 755 and g+s on cache/man,
but opening my in with mh-e still says either:
inc: unable to lock and fopen /var/spool/mail/busey
with permissions of /var/spool/mail/busey 660 (busey.mail owner/group)
or I can read the messages but not delete them with unsafe
permissions.
What should I change things to?
I'm ready to repurge everything, set /var as it should be, then
reinstall packages if necessary.
Any help or directions of where to look further would be appreciated!

Also look at the BIOS interrupt settings and try swapping between
level triggered and edge triggered interrupts.

Minicom cannot send or receive files. It can, however, run a separate
programme to send and receive files. Such as "sz" (send z-modem) or
"rz" (receive z-modem) (which are also used with some switches for x and y
modem transfers) or "kermit" (if you have that). It should be able to
send, not an ascii file, but ascii text from a file (taking the data and
typing it into the terminal for you).
Check the configuration (alt-o) and file_transfer protocols. Also check
the man pages on sz. You will have to edit the commands to reflect where
you have your versions of the programmes installed and perhaps change the
directories where they are saved (alt-o and the filnames and paths item).
Does your ISP offer you a dialup terminal account (not telnet - but a real
terminal emulation dialin)? If so, that is what minicom is best for.

I get the same message + hdb (= my cdrom) irq timeout + resetting ide(don't
know exact layout) sometimes lately when ripping cd's. The problem is,
ripping always worked fine. It isn't connected with scratched cd's either,
when I run cdscratchcheck (on windows), it happens also to cd's with a
scratch value of 45 (wich is very good, most new cd's have about 50-200,
old ones sometimes over 2000).
It doesn't look like an bandwith problem either, nothing else is using ide
too much, and it's a 32x cdrom drive, but I don't think it's broken yet.
What could cause it?

One thing to remember: you have to compile with optimization
enabled for the inb/outb functions to work.

I use vmware and really love it. It's a bit heavy on resources though,
I'm much happier with 256M of RAM than I was with 128M, my 450MHz K6 is
enough, but I don't even consider running it on my other machines, which
vary between a 120MHz Gateway Laptop with 48M of RAM on the slow end,
and and a 233 MHz Pentium desktop with 64M of RAM, second fastest to my
K6.
I've been reading good things about a program called win4lin, and am
consdering it for the slower machines when I get the time to play with
it.

They have a free evaluation version, and their prices are very good,
assuming you're willing to use proprietary software at any price, that
is... :-)

If you have spaces in the filename the shell is going to interpret
the parts as separate pieces unless you wrap quotes around them.

For anything moderately complicated that won't be repeated often
I usually read the initial filename list into vi (:r !ls pattern),
then use substitutions to turn it into the needed shell commands,
then :w !sh (pipe buffer through shell).

The shell will happily process things like */*/pattern.

I know of four packages that may do what you want:
- VMware (http://www.vmware.com)
- Win4Lin (http://www.netraverse.com/index.php)
- WINE (http://www.winehq.com)
- Willows TWIN (http://www.willows.com)
The first two are essentially machine emulators. You install Windows 9x
in the emulator and run it, allowing you to run most programs that run
in the native environment. Of the two, VMware does a more complete
machine emulation (you can run Linux, FreeBSD, Windows NT/2000, and
perhaps other OSs as well as Windows 9x and DOS), but is slower; Win4Lin
only allows you to run Win9x, but is much snappier in its emulation. The
two also differ in various other ways. Both are commercial packages
(Win4Lin is cheaper).
The second two re-implement the Windows API, so they don't let you run
Windows per se, but they do let you run Windows programs. Neither is
anywhere near complete, although a handful of useful programs run in
each. I occasionally try my collection of semi-important Windows
programs in WINE, and it usually runs about 5% of them well enough to be
useful. Each time, it comes closer to running at least some of the
remaining 95%, but it's rather like Zeno's Paradox -- the emulation
keeps getting 1/2 the way between the prior state and completion, but
it's never ALL the way there. I've not tried TWIN, so I don't know how
good it is from firsthand experience. WINE is open source, and I believe
TWIN is, too, although TWIN has corporate sponsorship.

Yep. You see, when you step through that command, what the shell is
trying to execute is this:
mv my - file my: file
which will not work; you want
mv "my - file" "my: file"
and the solution should be obvious from there.
( for i in *-* ; do
$j=`echo $i | sed -e 's/ - /:/' `
mv "$i" "$j"
done
)
>Also, how would I use these for multiple subdirectories at once?
TMTOWTDI, naturally. Put that command above into a script or a shell
function named "FOO", then do:
for i in LIST_OF_SUBDIRS ; do
cd $i
FOO
cd ..
done
Or you can use bash's argument variables $1 through $9; that way you can
pass the script parameters on the command line, cd to each directory in
turn, and run the echo/sed/mv thing inside of each directory. For bonus
points, figure out a way to make it recurse through a bunch of
directories. (use [] and -d!) Welcome to the nifty world of shell
programming.

That is not really a firewall matter. All the traffic necessary for
generating a pop-up can take place over port 80, and if you block port
80, you are going to have some very unhappy users. I suppose you could
set up the Squid proxy server and have it search through all HTTP
traffic for the Javascript commands that pop up additional windows and
silently terminate them with extreme prejudice. Your call, but the
easiest way to fix this is most likely to disable Javascript within
Netscape.

It appears as if I'm stuck without DSL/cablemodem access for at least 2
months, so I'd appreciate advice on a reasonable dial-up ISP in the
Lansing, MI, USA area.
I was looking at http://voyager.net ; they seem to have something
reasonable going on. Buried in the Tech Support section of their page
are DNS numbers, confirmation that they use PAP for authentication,
and info on POP3 and SMTP access. Everything I can see from there
makes me think that their service would work just fine with Linux.
Heck, I would've signed up with them on Friday, but they don't take AmEx
and my Visa card is currently lost in the depths of bureaucracy.[0]
Anyway, if anyone has concrete info on whether this ISP will perform
with Linux (or suggestions for a better one in the Lansing area!), I'd
appreciate it. Please post to the NG; I can use slrnpull to check it
from my job without the boss getting too upset....
