Re: [SLUG] Mutt Basics

I actually find it a little strange that many program options are set up from the shell using environment variables, for example for rtin: NNTPSERVER='news.xyz.com' export NNTPSERVER Why aren't these options available from within rtin/mutt ? It seems like strange practice .. :) other apps also use these env vars - hence not having to set them all over the place. I also don't understand the local mail server concept. Is it true that it's common practice to have a mail server on my system constantly receive mail and then offer it to my email programs - it seems like most email programs want to check local mail by default. mutt can have POP support built in, but the standard practise is to use a tool like fetchmail to retrieve the mail to your local machine first. mutt then checks somewhere like /var/spool/mail. sending mail requires you run a SMTP server (something simple like ssmtpd which does nothing other than forward to your ISP's mail server should be fine). when you use a more user friendly tool like netscape or evolution, they have a built in simple SMTP server for delivering mail to your ISP, and built in POP support for checking mail. cheers! -- Damien Elmes [EMAIL PROTECTED] -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug

You've found the need to delete a chunk of stuff, mark the beginning with

indent right, find matching left brace, then move the top brace back one
indent, find matching right brace, move that back one indent.
Basically, applying delete, yank, indent to some form of navigation,

Re: [SLUG] Multiple NICS under Linux
Bernhard Luder was once rumoured to have said: RTL8139 (10/100) works fine as well and costs less than $20 each. For values of fine implying low-performance. The PCI SMC cards that telstra give away with Bigpond Advance are RTL8139s. My experience has been that they do not handle heavy load too well - IMO they're not suitable for high-performance/high-demand environments running at 100Mps. You're better off tracking down a Netgear FA-310TX, or spending the extra money on a 3Com Etherlink XL (3c905 family) or Intel EtherExpress Pro 100. I personally use FA-310TXs and Etherlink XLs - Etherlink XLs tend to be plentiful and you can usually purchase them fairly cheaply second hand. The Etherlink XL is also supported by practically everything (I bought my Etherlink XLs because BeOS supported it, whereas it didn't support my Etherlink III [3c509]). The FA-310TX on the other hand was unbeatable value when Netgear was still producing them - especially at ~AUD$40 for a new card. My only RTL8139 in active duty is going to be replaced with a 3c905C when I get around to it.

[SLUG] OT: Vector data on Sydney CBD
Hi Group ! This question is a little off topic but since it is related to computers and geographical science I might have some luck asking the question here. 1) Has anyone used the CDROM version of the UBD Street Directory ? I'd like to hear opinions on the format used here, do you suppose it's vector or raster based ? This program is on display at the two-story Dymocks store in the city, it's pretty cool :) If it does use some kind of vector format, I wonder how difficult it would be to decompile the data files ? Would success here be unlikely ? 2) I am looking for simple but to-scale map of the Syndey CBD area. A flat projection of the streets would be fantastic but a scale model (including simple boxes for buildings) would really be the icing on the cake ! Any ideas on finding one ? 3) I have seen one real life scale model in the Town Hall House in the city, apparently there's another one at the Custom's House near Sydney Cove, check them out :) I wonder if the modellers have recorded their data on a computer ?

My problem is that this script checks the crontab running time against a DB file which has 8:50AM in it and doesn't match.. I can easily pass a parameter to say that it's an 8:50 run time even if it runs at 8:48 ot 8:49 yet the $1 parameter says 8:50 but that's a suck way to do it does crontab do this usually? thanks, George Vieira Systems Manager Citadel Computer Systems P/L
Re: [SLUG] OT: Vector data on Sydney CBD
Free map data for Australia would be really cool. A lot of the stuff comes from 'Public Sector Mapping Agencies'. The dept of lands for each state has the survey info for every 'parcel of land' - called cadastral data. The RTA, the railways, water board, county councils, every bloody department has some mapping data, none of it co-ordinated except by commercial bodies. None of it is free, yet we've already paid for it. The copyright must be a fine line. The raw data just is : the collation, the presentation is probably where the copyright applies. You are partially correct. The last GLIS survey was 1994, I believe, and that data is quite out of date (it was in 1995 !!). You will *not* get it for nothing, and in fact its quite expensive to purchase. I've been trying to get updated data for my Garmin eMap GPS for the last 6 months, as the stuff that Garmin were able to get suffers from a data translation problem - if the data is in (for example) AUS1994 format, and they converted it to NMEA or GARMIN format for the GPS, it shows points as being up to 500 metres out. For example, taking a reading from Richmond railway station with a 5 metre resolution (and access to 8 satellites) should be fairly accurate, yet the map says that I am 435 metres away from the station. Same applies for my offivce in the CBD - a reading (handheld, from the roof with 6 satellites and 10metre resolution) tells me that I work in Cockle Bay. To get the same accuracy as, for example, the USA enjoys (wether it be mapping CDs, GPS data or... *gasp*... M$ Roadmap) would cost you thousands of dollars, as it's not public domain in this country, whereas almost every other country on this planet that uses this makes it available either free or for a VERY minimal fee.

UBD being a commercial company makes no secret of the fact that they
have about 12 errors per map in their directory - these exists soley to
catch anyone breaching their copyright. Also the data is adjusted for
map presentation - not on road use.
Essentially UBD = Gregory's = Pacific Access = WhereIsIt = Yellow Pages.

Yes. At best, you will probably get a georeferenced raster image that

it and thought it was terrible and probably only good for a wall map.

When I explained what I wanted it for, AusLIG mumbled something about
$1/map for each download - right skip that.
None of it is free, yet we've already paid for it. The copyright

collation, the presentation is probably where the copyright applies.
The Geographic Information Systems industry is dominated by US companies
because the US governement took this approach. They have all this data
to play around with to develop product to sell. Australia has a USER

The expensive part in GIS is data acquisition. The real problem with

big problem.

Why Not?
1) GPS receivers are not accurate enough.
2) GPS receivers are not reliable enough.
3) GPS receivers have a coverage like mobile phones = big holes.
4) GPS receivers do not have the capacity (waypoints) = required laptop.
5) Cost - software - very expensive, or Grass
6) Cost - labour - who is going to pay the person to process the data?
For personal use, you could 'screen scrape' some whereis

where he has laid GPS data over this style of map.
On the positive side, someone (apologies forgot where I'm filing stuff)

Is anyone interested in this sort of thing? - i.e doing an open source

Bicycle Australia (http://www.woa.com.au/ba) has basically decided the
way forward for them is currently just to direct people to existing
commercial maps and later put some maps, as A5 landscape images, onto
WWW pages for people to download and print off themselves. Currently
each would need to be digitized and created as a graphic. It would be
better however, it there was an online GIS system that people could just
create the map they want.

if the data is in (for example) AUS1994 format, and they converted it to NMEA or

How is it out?

The US makes it available for the cost of delivery. Most other

[SLUG] Epson Printer Problem
Hello Slug, I have an old Epson LQ-570+, ESC/P2 dot matrix printer. It is still a great printer, my daughter uses it for school. The problem we are having is the printer seems to be set for too many lines per page. The first page prints out, but the print is close to the page bottom. Then the next page starts down too low and the bottom of that page prints on the next page. This gets progressively worse as multiple pages are printed. The only way we can print multiple page documents is to cue the printer to print each page separately. My brother suggested that the lines per page may need resetting. Does that sound like the problem? If so what is the solution? Any Help you could offer would be appreciated.

It's true you can make mutt retrieve mail from a pop server (only one though) but don't bother, use fetchmail to do it for you. For doco, have you checked /usr/doc/mutt* on your system? there's manuals and faqs etc that come with it (or see www.mutt.org). Mutt is simply a mail reader. So to do what you want you would normally have 3 programs working together: - fetchmail to retrieve your pop email - mutt to read it and compose email (MUA - mail user agent) - sendmail/postfix/exim/ssmtp (or whatever) to send the email out to your ISP (MTA - mail transfer agent) This is the traditional unix way of having small simple programs each doing a single job well. I also don't understand the local mail server concept. Is it true that it's common practice to have a mail server on my system constantly receive mail and then offer it to my email programs - it seems like most email programs want to check local mail by default. yes, in the case I've described above the MTA is your local mail server which receives the email (from fetchmail in this case) and stores it in /var/mail (or /var/spool/mail). So fetchmail retrieves the email from your ISP, passes it to your local MTA which stores it in /var/mail ready to be read by your MUA (ie. mutt).

[SLUG] Check my thinking please
Hi all, I need some collective wisdom on a process I have planned. I have AUC running on a RH7 server, no problems. However I want to add another package that requires me to rebuild Apache with MySql and PhP support - again no trouble using Apache toolbox, I have done this as far as 'make'. The original Apache server was installed by the RH installer, assumedly from an RPM. It is important that this server be down for a minimum of time ie minutes rather than hours. My thoughts are that I should be able to shutdown the existing Apache, unistall the RPM and then do the make install on my new server. Assuming I have the conf file correctly setup, with the web root and doc root in particular, then all I should have to do is to start the new server and we are back in business. If that works then I need to do something similar with MySQL as I have 'upgraded' from source over the top of an rpm install and there are stray files all over the place! So shutdown MySql, uninstall the server, get rid of any of the binaries from the source install - taking care to protect my databases - re-install (perhaps the binary version) and re-start.

Re: [SLUG] BIOS upgrade (OT... a bit)
Hi Slugs, The BIOS is all OK now and reading the larger HDD. The docs on the BIOS motherboard site said that the 2Mb BIOS upgrade accepts a larger HDD. The docs did not mention in the 1Mb upgrade that is fixes the large HDD problem. I only had a 1Mb BIOS not the 2Mb BIOS. So I flashed it anyway. Turned out to be the correct decision as the BIOS now recognises the larger HDD. To answer Grant Parnell's question, I did try to manually set the BIOS without auto to every config it would take.

They aren't any faster, they don't really have any special features over cheaper boards, etc etc .. so why do people buy them ? Should I just go with a Gigabyte board ?

Nope. Your data will survive on 2 drives. Three is the minimum drive
number for a raid 5 set. If a drive failure when you've only got 3 drives
lost data, then it couldn't legitimately be called raid. However, you run
huge risks {see point 2 below} if you don't replace it immediately.
Must I be including a hot spare? I know I should, but must I?
Of course not. However, there are advantages to doing so.
1) You are guaranteed matched drives. This might sound trivial, but if you
buy three drives and run them for, say, three years, have you any idea
what your chances are of replacing one which fails?
2) The onus of immediately replacing any failed drive {in a three drive
set} is reduced. Your hot spare takes over, and you've still got a valid
raid 5 set with full recoverability. You can withstand _two_ drive
failures in short order - and anyone who thinks that's unlikely hasn't
worked with large raid sets much. :-)
