[SLUG] PCMCIA 802.11g recommendations
Hi All, Yes I've STFW, Googled and checked the archives. I'm going to be upgrading my PCMCIA card on my lappy to support 802.11g (and possibly 802.11a + WPA) [1]. So far my search has yielded to potential candidates: Linksys WPC55AG [2] Netgear WG511U [3] I know to get either of these working I'll probably need to use that (evil) ndis wrapper and so gentle coaxing or possibly get them working with madwifi drivers. Does anyone have any specific experiences with either of these cards? So far I've only turned up info about models that are close (like the WPC55G and WG511T etc). Can anyone recommend an 802.11a/b/g card that supports WPA that DOES work under Linux? TIA James [1] Home is an 11b/g access point, work is 11g only (with WEP), Uni is 11a/b with WPA only (ie, no WPA==no link) [2] http://www.linksys.com/products/product.asp?grid=33scid=36prid=609 [3] http://www.netgear.com/products/details/WG511U.php -- If this fortune didn't exist, somebody would have invented it. pgpgTbm515zPU.pgp Description: PGP signature -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Also the advent of code checkers is discovering some of these exploits without intensive code review. There are always new exploits discovered and there are people who do University courses discovering those exploits the results are published. It is up to the projects to then take the problem seriously that can be difficult. Firefox is security conscious because it is being attacked but does terminal software require the same level of intense scrutiny? What would happen if I came up with an exploit in gnome-terminal would it be fixed immediately? It really does depend on the application.

[SLUG] Memory-mapping source files for faster lexical analysis
Hi all, I'm starting an honours year at uni this year. My supervisor and I are thinking of doing a paper on trying to determine if memory-mapping source files will speed up the lexical analysis phase of various compilers (instead of whatever buffering method it currently employs). While we can't find any similar publications on the subject that obviously doesn't mean no one out there has done anything on it. Has anyone heard of any work done on this kind of thing before? Thanks! -- Mike -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

IO-Lite is a related work for this. One thing to watch out for is that this is likely to be OS dependant; how the IO system, buffering and paging is implemented will have a large affect on results. From the systems I've tested on (MacOSX/PPC, Linux2.6.10/ia32), mmap is a much faster than alternatives, the question is however, how much impact that would have on the speed of the lexer. I think the main thing you would need to show first is that in current lexers I/O is the dominating factor, and not say, the actual lexing of the data. I wouldn't have expected I/O costs to be dominant, but a quick use of gprof would definately show one way or the other. gprof won't show the impact of seek times, nor blocking / async time. oprofile is a better choice AIUI. Also, trying a zero copy IO approach would be useful for comparison.

[SLUG] USB Wireless Dongles
'morning SLUGers, I have an iBook G4 which, on the weekend, at the codefest, nuked OSX from in turn for ubuntu. Everything works so far except sleep (which I'm going to look at) and the internal wireless (Airport Extreme). Any support for airport extreme looks sucky, so I want to get a USB wireless dongle (there's no PCMCIA slot). Right now I've been borrowing a netgear MA111 which works quiet well, but it's only 802.11b, and if possible, I'd like to go 802.11g. So, has anyone come across any 802.11g ones that work under linux (remembering ndiswrapper is not an option under PPC). And, if not, any reccomendations for an 802.11b one. A small usb flash-drive style is preferred. Cheers, - Chris -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

My supervisor and I are thinking of doing a paper on trying to determine if memory-mapping source files will speed up the lexical analysis phase of various compilers (instead of whatever buffering method it currently employs). The problem you've got is that lexical analysis makes heavy use of the C library's ungetc(). So gains from memory-mapped I/O are going to be lost implementing an alternative ungetc() [ie, you'll find yourself implementing the C stdio library]. Note that most of the I/O hit doesn't come from the initial lexical scan, but from the intermediate files. I'd expect C to have a lot more I/O attributable to lexing than most languages (because of it's use of .h files and it has two lexical passes -- one by the pre-compiler and one by the compiler). It's an area worth persisting with though, as almost every effort to drop the cost or amount of I/O when compiling a project has been a big win (see distcc, ccache, the gcc -pipe options, the argument for using include in Makefiles as opposed to heirarchical Makefiles, precompiled .h files). Operating systems have a hard time with compiling because of the bivariate nature of a compile -- repeatedly I/O-bound and then CPU-bound. So tuning based on recent activity (ie, most automatic tuning in OSs) fails to optimise. Personally, since this is just a honours project and you don't want something too open-ended, why not seek to accurately characterise the OS demands of a typical large project build (eg, Samba, Apache, etc). There's some nice work going on characterising the demands of the Linux boot sequence, and you could leverage those tools and techniques. Break the compiling process into stages (and the gcc tool chain is pretty modular so there's a reasonable but not complete mapping of stage to compiler program, but the tools I told you about above allow you to mark a stage transition with a small mod to the program). Now track the I/O and CPU attributable to each stage for various options (eg, heirachical v included Makefiles, -O optimisation levels, static v dynamic linking). Similarly for OS tuning. Enough raw material there for a very fine paper and thesis. -- Glen Turner Tel: (08) 8303 3936 or +61 8 8303 3936 Australia's Academic Research Network www.aarnet.edu.au -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

[SLUG] Cyrus
Hi All, Since it's been adopted as the standard IMAP server for UserLinux, I thought I'd check out Cyrus (on Debian Sarge). I am finding the documentation more unfriendly than is usual for free software (which is saying something), and third-party documentation rather thin on the ground. I am consequently having trouble getting my head around some fairly fundamental concepts. Or perhaps I'm just getting too old for this sort of thing, and my brain is no longer sufficiently elastic. I have set up /etc/imapd.conf for virtual domains with a global admin user as per the docs. However, when I try to set up a mailbox associated with a particular domain thus: # saslpasswd2 -c [EMAIL PROTECTED] # cyradm --user cyrus localhost localhost.localdomain cm [EMAIL PROTECTED] createmailbox: Permission denied Is the result. I can set up users without explicitly specifying a domain, which I suppose puts them in the default domain set in /etc/imapd.conf: localhost.localdomain cm user.name But curiously, I can't then delete the mailbox: localhost.localdomain dm user.name deletemailbox: Permission denied I am sure I'm missing something pretty basic, but I haven't the foggiest what that is.

Apache runs as uid gid 72, so I changed fstab to :- /dev/hdh1 /Win2k vfat defaults,umask=002,uid=72,gid=72 0 0 and remounted /Win2k. Still no dice, Apache wouldn't read it. ??? I added apache to root user group (yeah, I know... just as a test) but still didn't work - I thought that if apache was in the root group it should gain all the access priviliges of root ? Reason I'm using vfat is I want to be able to fall back immediately to Win2k dualbooted if something goes wrong with Linux... hence I've put email, working .docs etc on this common partition.

Re: [SLUG] Cyrus
Matthew Davidson wrote: Hi All, Since it's been adopted as the standard IMAP server for UserLinux, I thought I'd check out Cyrus (on Debian Sarge). I am finding the documentation more unfriendly than is usual for free software (which is saying something), and third-party documentation rather thin on the ground. I am consequently having trouble getting my head around some fairly fundamental concepts. Or perhaps I'm just getting too old for this sort of thing, and my brain is no longer sufficiently elastic. I have set up /etc/imapd.conf for virtual domains with a global admin user as per the docs. However, when I try to set up a mailbox associated with a particular domain thus: # saslpasswd2 -c [EMAIL PROTECTED] # cyradm --user cyrus localhost localhost.localdomain cm [EMAIL PROTECTED] createmailbox: Permission denied Is the result.

Re: [SLUG] security different on vfat compared to ext ?
So the situation you are describing is that you have a critical server on Linux that you want to be able to switch over to Windows if you screw up its setup? If that's the case then how about actually having another image of Linux on another partition and boot to it if you screw up the primary image? It would also mean that you have only one kind of OS and an entire set of software/patches/config files to share between the two images.

Re: [SLUG] PCMCIA 802.11g recommendations
James Gray wrote: Hi All, Yes I've STFW, Googled and checked the archives. I'm going to be upgrading my PCMCIA card on my lappy to support 802.11g (and possibly 802.11a + WPA) [1]. So far my search has yielded to potential candidates: Linksys WPC55AG [2] Netgear WG511U [3] I know to get either of these working I'll probably need to use that (evil) ndis wrapper and so gentle coaxing or possibly get them working with madwifi drivers. Does anyone have any specific experiences with either of these cards? So far I've only turned up info about models that are close (like the WPC55G and WG511T etc). Can anyone recommend an 802.11a/b/g card that supports WPA that DOES work under Linux? TIA James [1] Home is an 11b/g access point, work is 11g only (with WEP), Uni is 11a/b with WPA only (ie, no WPA==no link) [2] http://www.linksys.com/products/product.asp?grid=33scid=36prid=609 [3] http://www.netgear.com/products/details/WG511U.php I use a DLink DWL-G650 which is an Atheros based chip. Using the MADWiFi driver under Linux works. And yes I've even got it to work with WPA at UOW. However, since I installed the 2.6.8 kernel I had problems. This however was many months ago and have not investigated it since. I will however will be trying again very soon as uni has recommenced and I suspect there have been changes to MADWifi with better support under 2.6.x Anyway, I'll catch up with you at UOW and you can try out my card for yourself. All findings of course shall be posted to SLUG. :) - Rocci. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Check the logs; cyrus (at least the old 1.5 which I'm still using) is pretty good at logging why things failed. Also, the global admin user may still need cm perms on the specific vdomain, although that I'm not so sure of.
