It's not env but the kernel, and it looks like it's
deliberate:

Also, consider perlrun's comment:

 There is no general solution to all of this.  It's just a mess.

Yeah, I meant env plus the bits to custom find your
real interpreter and possibly interpret additional lines
to get the args blah blah of course!  And without doing
anything of things that env really does, like actual env
stuff!

Because that 5 hours is not set in concrete. This is Telstra don't forget.
Besides, there's a million other reasons why the link could drop.  Also, if I
deliberately drop the link at 4 H 50 M, my users would be down for no really
good reason.  I've got enough problems keeping them happy as it is.

When the ping fails, I'm also doing killall pppd & pptpd before starting a new
tunnel. This should hopefully correct what James was saying about bringing up
multiple tunnels. Just checked the tunnel. It's been up for the last 14 hours &
working fine.

Re: [SLUG] Cross platform interpreter invocation

[mlh]

You could write your own env equivalent.
It's quite a simple program.

But! I suspect that the problem is not env,
but the kernel; whether and how it passes args
to the interpreter.

For perl, does the the '$if_running_under_some_shell'
hack do what you want to do?

I got a Zaurus SL-A300 recently. It's a Japanese only model hence a little
different -- smaller and without a physical keyboard, but it has good pen
input which is great for writing Japanese :)

I use it mostly for Horms' jiten (Japanese/English dictionary program),
but also for taking short notes and viewing photos. I transfer data back
and forth via an SD card -- it does have USB but I heard a rumour that it's
not USB storage and needs some special USB net software so haven't bothered.
I don't use the diary, but I do use the address book if only for the gimmick
value of actually being able to store Japanese friends' names in Japanese :)

Back on topic however, it's great being able to drop to a shell and poke
around. It runs a patched 2.4.13-ac5-rmk2- kernel out of the box, and of
course you can install random qtopia apps on it or even build stuff for it.
Plus you always know it's Linux under the hood, so it multitasks well and
corrects for daylight savings automatically etc. ...

Usability-wise, hunt-and-peck on a soft keyboard is a pretty painful way to
take more than a couple of lines of notes, or to use a shell at all, but
I'd imagine the physical keyboard would be a little faster.

cheers,

Conrad.

[SLUG] USB Printer

[Edwin Humphries]

We're trying to share an Epson USB printer via Samba on our new Fedora server.

The share is set up OK, and can be seen and opened from Windows clients. However, 
although the Fedora box can print to the Epson, the Windows boxes can.

All other Samba shares, including a laser printer connected to the parallel port, 
work fine.

Does anyone have a clue how to fix this?

Fairly sure. Google suggests it does. Compare

Certainly does on my box:

$ cat t
#!/usr/bin/env perl -w
$ ./t
/usr/bin/env: perl -w: No such file or directory

Maybe I need a more cutting-edge env.

[SLUG] NSW targets employers' email snooping

[Howard Lowndes]

I guess there are a few of out there that will be needing some legal
opinions on this one and some re-defined acceptable practice
conditions.  It looks like a minefield.


http://www.abc.net.au/news/newsitems/s1077250.htm

The New South Wales Government is moving to outlaw bosses spying on
workers' emails, unless they have a court order to do so.

The step is said to be an Australian first.

New South Wales Attorney-General Bob Debus says the union movement has
been justifiably lobbying for laws to stop employers from spying on
workers' emails.

"The Government proposes to tackle this problem and in this respect we
will be the first Australian state to do so," Mr Debus said.

"Under the template proposed by the Government, a balance will be struck
between the employee's right to privacy and the legitimate needs of
employers to protect their intellectual and commercial properties," he
said.

He says the laws being drafted will not place a blanket ban on email
surveillance but will make sure it is done ethically.

Mr Debus says the new laws will make it a criminal offence to undertake
any form of covert surveillance unless an employer can show a reasonable
suspicion of wrong-doing by an employee.

"Unless employers have a court order, they will need to give employees
notice that surveillance will be conducted," he said.

That could mean a warning box pops up when the computer is turned on.

RE: [SLUG] Cross platform interpreter invocation

[Rowling, Jill]

I recently had to handle a similar problem on a cross-platform PERL script.
If you can guarantee that your path is correct, i.e. `python` or (in my
case) `perl` will run the appropriate interpreter, then you should be able
to pass it the path to the script as an argument.
In my case,
perl /path/to/my/script
Worked OK even though the header in my script had
#!/wrong/path/to/interpreter.
In your case,
python /path/to/your/script
Should work on all platforms.
The -w argument, if required for PERL should be invoked:
perl -w /path/to/my/script

Hope that helps,

- Jill.

In general I've found the easiest way is the cop-out of making a wrapper
script that finds perl/python (or in my case I have the wrapper script
generated out of a make rule that substitutes the appropriate
system-specific values) and execs it along with any arguments you need.

Pretty messy, but it's the best I've come up with in the past. I'd also
be interested in a better way.

HTH,

James.

Why not do it the other way around and bring the connect down every 4h
50 min.  That way you could stop/halt/suspend anything that requires the
link and then restart once the link is back up

Thats always been the case. STP is not appropriate to have on random
switch ports... STP simply allows one to build a redundant LAN
infrastructure.

Re: [SLUG] Is SATA a viable upgrade for aging Linux workstations?

You should already know ;)

  ATA is/was the "new" name for IDE (Integrated Drive Electronics).  ATA (Advanced Technology Attachment) is the official ANSI (American National Standards Institute) name for IDE.

  S/P are Serial and Parallel, respectively.  SATA is the "new" technology, and since it has come into use, we had to start using PATA (instead of IDE) to tell them apart.

  So, generally speaking, they are the names for the interfaces connecting your mainboard to your hard drive.

  Older technology used names like RLL, MFM, ESDI.  Still commonly used on high end systems are SCSI and sometime FC and FC-AL (Fibre Channel-Arbitrated Loop).

Re: [SLUG] Is SATA a viable upgrade for aging Linux workstations?

[David]

for those of us who aren't up with the latest acronym, what exactly is
PATA and SATA, and should I already know??

Safe mode is already off. I'll trying doing a chmod on the uploaded temporary
file before I move it. And yes, the file name is correct (it's held in a variable).
