I used to use a shell script that would use diff to compare two directories and all their subdirectories. I mainly used it to verify that a backup CD of crucial data had been written correctly. I have since written it as a perl script which is a bit nicer. Note that I have never got around to tidying up this script to use proper arguments, etc. It currently is set to comparing the current directory to the CD. Edit the line "@totals = &dodir(".","/media/cdrom");" if you want to change the directories it uses. Cut out the script from below and save it as whatever you want to call it and remember to set the execute bit on it. #!/usr/bin/perl # sub dodir { local ($dir) = $_[0]; local ($refdir) = $_[1]; local (@totals) = (0,0,0,0); opendir(F,$dir) || die "ERROR: cannot opendir $dir"; foreach $name (sort readdir(F)) { if ($name ne "." && $name ne "..") { $fullname = $dir . "/" . $name; $refname = $refdir . "/" . $name; if (-d $fullname) { printf "%-50s [d] ", $fullname; if (! -d $refname) { print "ERROR - not on CD\n"; $totals[0]++; }else{ print "(entering)\n"; @subtot = dodir($fullname, $refname); $totals[0] = $totals[0] + $subtot[0]; $totals[1] = $totals[1] + $subtot[1]; $totals[2] = $totals[2] + $subtot[2]; $totals[3] = $totals[3] + $subtot[3]; } }elsif (-f $fullname) { printf "%-50s ... ",$fullname; if (! -f $refname) { print "ERROR - not on CD\n"; $totals[1]++; }else{ $retval = system("cmp -s '$refname' '$fullname'"); if ($retval != 0) { print "ERROR - files differ.\n"; $totals[2]++; }else{ print "OK.\n"; } } }else{ printf "%-50s [can't handle]\n",$fullname ; $totals[3]++; } } } closedir(F); @totals; } $ok = 1; @totals = &dodir(".","/media/cdrom"); print "\n"; if ($totals[3] > 0) { if ($totals[3] == 1) { print "WARNING: There was one [reference] file that I couldn't read.\n"; }else{ print "WARNING: There were $totals[3] [reference] files that I couldn't read.\n"; } } if ($totals[0] > 0) { $ok = 0; if ($totals[0] == 1) { print "WARNING: There was one missing directory.\n"; }else{ print "WARNING: There were $totals[0] missing directories.\n"; } } if ($totals[1] > 0) { $ok = 0; if ($totals[1] == 1) { print "WARNING: There was one missing file.\n"; }else{ print "WARNING: There were $totals[1] missing files.\n"; } } if ($totals[2] > 0) { $ok = 0; if ($totals[2] == 1) { print "WARNING: There was one bad file.\n"; }else{ print "WARNING: There were $totals[2] bad files.\n"; } } if ($ok) { print "All OK.\n"; } Cheers Michael

RE: [wlug] Memory for weird things.
by Lindsay Druett 24 Jul '03

Well, up until now, I had been using Kingston RAM in Cisco devices, however, if the equipment is under warranty and/or under contract with Cisco directly, then there is a fundamental issue with using Kingston RAM which is not the case with using the RAM from these guys. These guys seem to be cheaper than purchasing Kingston RAM for Cisco devices from TP. That's also taking in account exchange rates, delivery, etc. Also with my experience with delivery, well, let's put it this way. If Federal Express opened business in New Zealand, then all the other couriers (CourierPost, NZ Couriers, etc, etc) would be out of business within no time. -----Original Message----- From: David Nicholls Sent: Thu 24/07/2003 9:16 a.m. To: wlug Cc: Subject: RE: [wlug] Memory for weird things. jeepers you guys, why not just order kingston ram? you can order equivalents for every system from dell to hp to whatever, and its cheaper. thats what the uni does. we just go to the kingston site and match system codes to get the right ram (i think its the us site so the price roughly doubles of course), then we order from NZ suppliers. theres bound to be someone around who is cheaper than our "oficial" supplier (tech pacific) that gets in kingston ram. cheers... david -----Original Message----- Oliver Jones wrote: > Howdy.

I've done that and selected the ppp option. If I were you, I'd start by reading http://www.wlug.org.nz/HowFirewallingWorks, I'd skim-read about how Perry's firewalling script works (at http://www.wlug.org.nz/PerrysFirewallingScript) and then I would install the .deb, which I'd find at http://www.wlug.org.nz/archive/debian/linuxserver-firewall_0.3_all.deb. (hint: wget the file, then dpkg -i) Then, you need to go into /etc/linuxserver-firewall/interfaces.d, check the mapping between interfaces and classes (which you learnt about in your skim-read), edit the files as required and type '/etc/init.d/linuxserver-firewall restart' And then you're done, and you did some good learning along the way too. ;) Future versions of the Debian package will do automatic guessing of interfaces and network addresses.

Glen I sent you a long text off list, Hope it helps Covers IP routing and stuff, You probably only need the last bit, but ut was easier to send it all to you.

Howdy. Thought I'd let people know I've found and awesome supplier of weird memory. I wanted to upgrade our HP 1300 from it's puny 16MB of ram to 80MB. Basically so large OpenOffice docs print without barfing half way through. Techpac are the suppliers of HP gear in NZ. Their prices for ram upgrades on printers are stupidly high. Well you can get 64MB upgrade for a 1300 from www.MemoryX.net for 30 USD + ~ 30 USD for FedEx express. It costs 10 times as much to buy the same ram from Techpac.

For some reason when I type vcopsystems.com, my mozilla browser corrects my obvious mistake to www.vcopsystems.com and it fails, even when it folow the link it works in that i see the page, but the address bar shows the www, which is wrong, thus my cut and paste was wrong link, in short annoying, Galeon does the same, so its probably an error in the core, must be time to upgrade it. All the rest of my mozilla installs work fine. its just that machine, its also the first time I've noticed it.

And the short answer is that >it won't. You will find that it does some things better (might be more >stable, might have more functions), but it does some things worse. Or >everything differently. > > We have no idea what they want to use it for on Windows though. For you to make the statement on the wiki, along the lines of 'All this linux sofware is at a basic equivalence level with its Windows partner' is completely missing the point, that you actually have no idea what people want to do with it or not. Moreover, the statement as it stands is highly likely to put anyone off using the alternatives - they are only a basic equivalent after all.[1] One example here. Gnumeric is a very polished replacement for Excel. It supports all the Excel spreadsheet functions, and a whole lot more. It doesn't have VBA, but I'm to understand that it supports perl/python/tcl scripting instead. It has a graph builder, advanced mathematical support, solver support, etc etc, and can even read / write Excel95/97/2k etc files. This is completely irrelevant if the user wants to build a basic spreadsheet with a few SUM and AVERAGE functions thrown in, and some formatting. Its completely irrelevant if the user is actually, due to its nice column layout structure, using it to generate a template for school reports. I have no idea what the user wants to use it for, and therefore I can only suggest that it might do the job. Likewise: VS is perhaps the de facto IDE under windows. Thats nice. It's entirely possible you'd be able to code just as well, if not better, under vim, or emacs, or joe, with another xterm open and use of make / gdb and cvs. It is perhaps worth noting that joe isn't as feature-full as VS (in fact, its just a text editor), but that is rather different from implying that there is no way to do the things you do in VS, under linux. >If your concern is "Linux Acts Just Like Windows Does" then Windows scores >100% and Linux scores in the lower half of the spectrum. That was the point >I was trying to make. Linux's goal isn't to OSS Windows (interestingly, > > If you meant this, you said it very badly. As what you had said sounded more like "Nothing under Linux does as good a job as the Windows version", which is a very broad reaching statement, and I might add, highly subjective based on your view of what people actually want to do with a program under Windows or Linux. It *is* fair to say that there are differences in the program, and that while Openoffice.Org Writer or Abiword might, at first blush, be an adequate replacement for MS Word, but lack some features that *some* people *might* want, but that wasn't what you were saying. While we're on the discussion of that wiki page, it was asking for what people use instead of a program under Windows. I dont use Windows. So instead of using MS Word, I use Abiword. It doesn't matter at all if its feature-equivalent to the MS Word. It's WHAT I USE UNDER LINUX. Likewise, I use gvim/gcc/make/cvs/gdb under Linux for development. It's *my* IDE. Highly subjective, of course, but the page was asking for individual responses. >there is a project that aims to do this, and they almost have NT4's cmd.exe >down pat). It will keep evolving whichever way it does. Linux doesn't have >the commercial app support (and it may never, and it may never matter). You >can't do everything you can do in Windows on it. But the price of freedom > > I dont see that 'you can't do everything you can do in Windows on it' is true. I *can* do everything that *I* do in Windows under linux. You can propose that 'Joe Windows User' would say otherwise if you like, but until we actually have a good, objective, understanding of what 'Joe Windows User' actually does with his computer, then its all speculation, and as I pointed out before, highly subjective and based on our own view. As far as I'm concerned, there is nothing stopping people using linux as a desktop fulltime. You disagree. Who of us is right? Daniel (From his linux desktop, on which he does all his work, and all the stuff he would want to do in Windows) [1] IF you want to do real comparisons, then do a feature matrix. And do full comparisons, so list things that both equivalents do, or perhaps grade them if you think one is better. Phil's comparison of The Gimp to Photoshop is a good candidate here, as would a comparison bettween MS Office and Abiword, Gnumeric, Oo.O, Kword, etc etc.

Mandrake 9.1 and Red Hat 9
by Matthias Dallmeier 19 Jun '03

19 Jun '03

Anyone who wants a three-CD set of Mandrake 9.1 or Red Hat 9, please let me know as soon as possible and bring along $5 to the meeting on Monday. If you cannot afford $5 or are not interested in attending the meeting, feel free to bring your own blank CDs (including at least one additional CD for the obligatory coaster) to 35 Galway Ave, Hamilton East and I can put Mandrake 9.1 or Red Hat 9 on them for free. Please write me an e-mail or give me a call on 021 615104 to make an "appointment" before you turn up at my place though. Thank you. -- Matthias
