Re: [SLUG] Best (most efficient method) recursive dir DEL
On 22 May 2014, at 9:10, Kyle k...@attitia.com wrote: Hi folks, I was wondering what is the best (as in most efficient method) for doing an automated, scheduled recursive search and DEL exercise. The scheduled part is just a cron job, no problem. But what's the most efficient method to loop a given structure and remove all (non-empty) directories below the top dir? The 3 examples I've come up with are; find top_dir -name name_to_find_and_DEL -exec rm -rf {} \; - what's the '\' for and is it necessary? rm -rf `find top_dir -type d -name name_to_find_and_DEL` - does it actually require the ' ` ' or are ' ' ' good enough? find top_dir -name 'name_to_find_and_DEL' -type d -delete- or won't this work for a non-empty dir? How do you define most efficient? Run time? CPU cycles? Memory usage? Forks? Disk reads/writes? Readability/maintainability? My personal guess is that a find command that locates the things you want to delete and ends with -print0 | xargs -0 rm -rf will satisfy most of those criteria. (Xargs will stuff as many file names as it thinks will fit on the command line, but sometimes it gets ambitious - you might have to use xargs -0 -n 100 rm -rf to limit it to 100 file names per invocation of rm) Or is there a more efficient manner which I can slot into a cron job? Much appreciate the input. -- Kind Regards Kyle -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

[SLUG] Reminder: Election closes 27/04/2012 16:00 (Sydney time)
One last reminder: voting for the new sub-committee is currently open at https://www.linux.org.au/membership/index.php?page=view-electionid=17 Voting closes at 27/04/2012 16:00, Sydney time. Although there are 3 advertised positions, we have 4 candidates. It is the intent of the current sub-committee to request that the LA Council appoint all 4 candidates be accepted as the new sub-committee - unless one of the 4 candidates gets significantly fewer votes than the other 3. Voting is optional preferential - you choose your most preferred candidate, and can then optionally rank more candidates below them in the order you'd prefer to see them elected to the position. If there's anyone you don't want to see elected at all, rank your other preferences but abstain from voting for the person you don't want to see elected. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] Bar Code scanners
You have an Android phone, right? http://www.mattcutts.com/blog/android-barcode-scanner/ That page has 6 lines of python that read the URL - but 2 of those are turning it into a url and looking up the book on Google Books. All you want to do is record the barcode, so you'll want to tweak that a little bit - you probably just want to record the ISBNs to a text file and look up the details later.

[SLUG] Election update - nominations close tonight!
Just a reminder that nominations for the SLUG election close *tonight* (12th Apr 2012) at 23:59 Sydney time. If you want to become a candidate in the election before then, you need to: * Already be a Linux Australia member (it's unlikely that new applications for membership will have time to be processed before time runs out) * Have two LA members nominate you at https://www.linux.org.au/membership/index.php?page=view-electionid=17 (you can nominate yourself) * Accept your nomination at https://www.linux.org.au/membership/index.php?page=view-electionid=17 Voting will open at 13/04/2012 00:00 (yes, a minute after nominations close). The voting process used in the election is optional preferential - that is, you nominate your first preference, then your second preference, and so on. You must give at least a first preference, but can choose to abstain from giving a preference for the rest of the candidates. If the 4th-place candidate in the election gets a similar number of votes as the first 3 people, we (the current members of the SLUG sub-committee) intend to ask the LA council to appoint all 4 candidates to the sub-committee for the next year. If there's a candidate you don't want to see on the sub-committee at all, don't list them as your 4th preference - you should choose to abstain from voting for them entirely. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] 2012 sub-committee election: nominations open today
It's been 12 months since Tim, Patrick, Neil, and I were elected as the last SLUG committee - which means it's time to have the first election of members to the Linux Australia sub-committee that now runs SLUG meetings. We're looking for 3 subcommittee members to run SLUG for the next year. A SLUG subcommittee member helps run the subcommittee, organising meetups and talks. A subcommittee member also represents the SLUG membership to the Linux Australia council. The election will be held online using Linux Australia's membership system, which handles the LA committee elections each. Nominations will open today at midday (AEDT), at which time you'll be able to view the election at https://www.linux.org.au/membership/index.php?page=elections. In order to become a candidate in the election a person will need to be nominated by two Linux Australia members (yes, you can nominate yourself), and will need to accept their nomination before the end of the nomination period. Nominations will remain open until 12/04/2012 23:59. Voting will open at 13/04/2012 00:00 and run until 27/04/2012 16:00, and the results will be announced at 27/04/2012 18:00, just before our April meeting. In order to nominate someone, accept a nomination, or vote, you'll need to be a Linux Australia member. LA membership is free - you can visit https://www.linux.org.au/membership/ to sign up. I'll be at the SLUG meeting on Friday night to answer any questions and guilt you all into joining the committee. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

[SLUG] Notice of Extraordinary General Meeting - Friday March 25 2011
Dear Sydney Linux Users Group, Notice is hereby given that the Sydney Linux Users Group will hold an Extraordinary General Meeting directly before its Annual General Meeting on Friday 25th March 2011, at the same venue as previously announced for the AGM at [1]. The meeting is convened to consider, and if thought fit, pass as a special resolution, several motions concerning the winding up of the association. The EGM will commence as soon after 6:30pm as is practical. [1] http://lists.slug.org.au/archives/announce/2011/02/msg6.html - The motions to be considered at this meeting are as follows: 1) In recognition of the fact that the aims and goals of SLUG are substantially a subset of those of Linux Australia; and furthermore, that Linux Australia is better equipped to support and sustain SLUG’s community; and further, that having SLUG exist as an Association results in a duplication of effort and inefficient use of resources - that SLUG be wound up as an association. 2) In accordance with the Associations Incorporation Act 2009 section 65, that all surplus property and funds at the time SLUG is wound up be donated to Linux Australia. 3) As the property and funds donated to Linux Australia in this way were originally donated to SLUG with intent to be used to support the open source community in the Sydney area, that we request that Linux Australia continue use the property and funds to support the open source community in the Sydney area. 4) In recognition of the fact that there exists a thriving open source community in the Sydney area, that the above actions not be taken until such time has Linux Australia has: - Created a sub-committee, charged with supporting the Sydney open source community by running monthly meetings, and by providing other such support as may be warranted; and - Appointed to that sub-committee, at minimum, the person elected as president at the next AGM to be the convenor of the subcommittee; and as treasurer, the person elected as treasurer at the same AGM; -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

[SLUG] Notice of AGM: 25th March 2011
Dear Sydney Linux Users Group members, This message is to give notice that the Sydney Linux Users Group will hold its Annual General Meeting of Members on Friday March 25th 2011 at the Google office, 48 Pirrama Rd, Sydney, NSW, Australia. Please note that the building’s front doors close at 6:30pm and access after this time is not guaranteed. The AGM will be commencing at approximately 7pm. Only current financial members will be eligible to vote, but all are welcome to attend the AGM. Please also note that your 2010 membership expires immediately before the AGM commences - only a 2011 membership is valid. Our Treasurer will be selling memberships before the AGM (and memberships be at the February meeting if you’d like to get yours early). For a user-friendly guide to the AGM, see [0]. Members unable to attend the meeting may raise issues for the committee to respond to either publicly, by mailing the SLUG Activities mailing list[1], or privately by mailing the Committee directly at commit...@slug.org.au. The draft agenda for the meeting is available online at [2]. The minutes from the 2010 AGM are at [3] for you to review prior to the 2011 AGM. Members interested in serving on the Committee are highly encouraged to nominate themselves for one or more positions. Most of the existing committee members have indicated that they will not be running for re-election. SLUG membership is $15 for students, and $25 for everyone else. Voting will occur at the meeting by show of hands by financial members (identified by possession of a membership card). Members unable to attend in person may appoint a proxy to vote on their behalf, in accordance with Section 4.11, and Appendix 2, of the SLUG constitution[4]. Parties should notify the secretary of their appointment of a proxy via digitally signed e-mail to commit...@slug.org.au, using the form mentioned in Appendix 2. The committee will ask that the members ratify its activities as detailed in the office bearers' reports were in accordance with the organisation's aims. These reports will be presented at the AGM. On behalf of the committee I would like to thank you for your continued interest in SLUG and involvement with the community to date, and encourage you to pass on any questions or ideas you may have about the organisation's future to the SLUG Activities mailing list or the committee directly.

[SLUG] Motion to be put at the AGM: Wind up SLUG
I've BCCed the main SLUG list on this email; please direct responses to the activities@ list. SLUG is an incorporated association. This places many burdens on the association; in the main, we end up merely duplicating work and expenses that Linux Australia does. In addition, the aims and goals of SLUG seem to largely mirror those of Linux Australia - with the exception that SLUG is exclusively focused on the Sydney area while LA has a larger scope. I'm proposing that we ask LA to take over the functions SLUG has performed, and then wind up SLUG as an association. This move would free the local open source community from: - The requirement to have a Public Officer for SLUG (LA has a public officer already) - Requirements to lodge reports with the Dept. Fair Trading (LA has to lodge more paperwork than SLUG does; but taking on SLUG's responsibilities would not add to their burden) - $800/year in insurance - this currently consumes almost 100% of our income. If freed from this burden, we would not need to ask for membership fees (LAs existing insurance would cover SLUG at no extra cost, if SLUG was a subcommittee of LA) - The requirement to have more than two members on the committee (more on this later) (It's still a good idea to have 2 people, and we probably want to have 3-4 - but as a subcommittee we can tweak that number as needed, whereas now we're required to have at least 4; and tweaking requires a special resolution to be passed at a General Meeting..) The suggested structure for a replacement for SLUG is as follows: - Linux Australia would create a subcomittee (tentatively named the Sydney Linux User Group subcommittee), and delegate to this subcommittee the responsibility of running regular meetings and coordinating other such activities as may seem useful to support the open source communities in and around Sydney. - The subcommittee can later, as needed, recruit other members as required - Linux Australia will appoint two people to this subcommittee: the people elected as President at the SLUG AGM in March 2011 to act as convenor of the subcommittee, and the person elected as treasurer to act as treasurer for the subcommittee - SLUG would, pursuant to a Special Resolution passed at the March 2011 AGM, apply to the Director-General for approval to wind up the association - SLUG would, pursuant to the same Special Resolution, apply to the Director-General to disburse all assets to LA, to be used by LA to support the operations of the SLUG subcommittee I’ve drafted the motion I’d like to put at the AGM onto the wiki (http://wiki.slug.org.au/windup). The final wording needs to be announced 21 days before the AGM, so please submit any feedback you have in the next few days.

Re: [SLUG] coding
Depends on what you're trying to accomplish. However, there's not much point running through both grep and sed - sed's featureset is (roughly) a super-set of grep: andromeda:tmp polleyj$ cat afile.txt This is a line This is another This is the third line And this is a fourth. andromeda:tmp polleyj$ grep line afile.txt | sed 's/third/second/' This is a line This is the second line andromeda:tmp polleyj$ sed -e '/line/!d' -e 's/third/second/' afile.txt This is a line This is the second line andromeda:tmp polleyj$ The various arguments and parameters passed to sed are described under `man sed`.

[SLUG] SLUG picnic - Dec 18 2010
Instead of having a meeting on the 5th Friday of December (which this year would be the 31st), we traditionally have a picnic around mid-month. This year, that picnic will be on Dec 18th. We're still deciding on a venue: the top contenders at present are: - Pyrmont Point Park - http://goo.gl/maps/NDbt (the aerial pictures there are woefully out of date; the park now extends all the way along Pirrama Rd as far as the intersection with Harris St - http://www.nearmap.com/?ll=-33.863952,151.191809z=18t=hnmd=20100916 has a more recent picture). The park has 5 free BBQs and a cafe and children's playground in the newer area - Blackburn Gardens - http://goo.gl/maps/RgIH, http://www.woollahra.nsw.gov.au/services/parks/parks_and_playgrounds/blackburn_gardens - has a beach, gardens, a cafe, and a library If you have comments on either of these, or other suggestions, please comment or suggest by the 24th, so that we can announce the location at this month's meeting. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Ubuntu’s Canonical decided that, they needed a more event driven init system and both Ubuntu and Fedora have been using Upstart in a backwards compatible arrangement for more than 3 years but with 10.04 are now starting to move away from the old init scripts. ==BOFs== OLPC Friends: Sridhar Dhanapalan will be giving a brief talk an QA session about OLPC Australia’s recent deployment in Yirrkala in East Arnhem Land. ===Second Half=== ==Main Presentation== Erik de Castro Lopo: Programming: How can we do it better? Part II (Part I available at http://www.youtube.com/watch?v=tZDy7ExHjMM) As developers, we hear a constant stream of complaints about how software (not necessarily our own) is buggy and crashes. In this presentation I plan to look at what we can do now and in the future to make software development more reliable, repeatable and scalable. ==BOFs== =Multimedia= Peter Chubb - Basics of shell scripting Peter will cover #!, variables, including arguments and shift, pipelines and jobs, and the 'while' statemnent. Presentation will be in a tutorial format - you'll get more out of it if you can bring a laptop and follow along.

Please don't think that your presentation has to be something enormous (e.g. how to recreate Ben Hur using FOSS). It can be something very simple as well. Time is also flexible in terms of your presentation - if you just want to show how to do something cool which only takes a few minutes, then this will be readily accepted too. For all you know the application, tool, format or process may well be unknown to the rest of us. You can even video the presentation if you like (screenshots etc) and we can run that. Any new apps etc are always good to highlight. If you send me your idea/s, I can then arrange with you how to present etc and send a schedule out so that we can let the rest of the list know what's happening in the multi-media BOF. This was we can attract more interest and more attendees :)) So, put on your thinking caps and get to it. Remember: Don't be too shy :)) Regards, Patrick Just to add a tiny bit of impetus to what Patrick has said - I'm hoping to be able to send an announcement about the meeting tomorrow (ie, Tuesday, possibly today by the time you're reading this) night; it would be awesome if you could contact Patrick today so that he can put a program together before I send the announcement. -- Linux - you use it everyday -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] March meeting: AGM + Programming: How can we do it better?
Date: Friday 26th of March Start Time: Arrive at 6:00pm for a 6:30pm sharp start Format: Erik de Castro Lopo on Programming: How can we do it better?, AGM, Pizza Dinner Where: Google Australia, Level 5, 48 Pirrama Road, Pyrmont (opposite Star City) As this meeting contains the AGM, all previous memberships expire and you'll have to pay dues ($25, $15 concession) if you wish to remain financial (including if you wish to participate in the election). First up, we have Erik de Castro Lopo, speaking on the topic of Programming : How can we do it better? As developers, we hear a constant stream of complaints about how software (not necessarily our own) is buggy and crashes. In this presentation I plan to look at what we can do now and in the future to make software development more reliable, repeatable and scalable. This will be followed (after the break) by the 2010 AGM - see [1] and [2] for more details. Meeting Details SLUG is the very mis-named Sydney Linux User Group. We are a general Open Source interest group which runs our primary event on the last Friday of every month (except December). Meetings are open to the general public, and are free of charge. Our venue is Google, Level 5, 48 Pirrama Road, Pyrmont. It's across the road from Star City Casino. You will need to sign-in to enter the venue. This can be performed when you arrive, but to help us organise adequate catering we ask that you do so online beforehand at [3]. If you are unsure, please sign up as a 'maybe'. This allows us to organise adequate meeting space and facilities. You do not need to create an account to indicate your attendance. Meeting Schedule We start at 18.30 but we ask that people arrive at least 15 minutes early so we an all get into the building and start on time. Please do not arrive before 18.00, as it may hinder business activities for our host! * 18.15: Open Doors * 18.30: Announcements, News, Introductions * 18.45: Programming: How can we do it better? * 19.30: Intermission * 19.45: AGM * 20.30: Dinner Hacker Space We have heaps of room available to us at Google. If the talks do not grab you, feel free to come along and hack away on your favourite project in the designated Hacker Space. Dinner We order in a selection of pizzas for dinner after the meeting. The cost is $10 per head, and we will be collecting money from the beginning of the meeting. If you have any particular dietary requirements (e.g. vegetarian), let us know beforehand. Dinner is a great way to socialise and learn in a relaxed atmosphere :) For those who want to continue the conversation after dinner, some of us will be heading to a pub in the local area.

Re: [SLUG] Syncable wiki?
The slug wiki (horrendous as it is) is DokuWiki, which amongst its other features, stores all its data in plain text files on disk, which makes it amenable to all the usual tools for dealing with textual content - eg, stick it inside bzr, people can check it out, take a copy with them, and merge changes when they get home. As the files are plain-text, they should be somewhat readable on a PDA... http://www.dokuwiki.org/dokuwiki for more details. The next nearest thing I know of (aside from ikiwiki, which I hadn't heard of till Rob mentioned it) is TiddlyWiki (http://www.tiddlywiki.com/) - it's a self-hosting wiki-in-a-file where all the code to make the wiki work is in javascript inside the file. It's portable, bzr might work to merge changes (I don't know, haven't tried, don't know enough about its innards). It definitely makes it easy to take a copy with you on a thumb drive or similar, but I don't know how all the JS is going to render on a small screen.

Re: [SLUG] GPS data logger
If you're specifically looking for running, Garmin make a nice range of sports gps/heartrate monitor/watches called Forerunner. They don't provide any linux support; but gpsbabel can apparently get most data from them (including heartrate date, so you can see how your heart rate varies over time as well as the track). there's also garmintools ( http://code.google.com/p/garmintools/) but it only works on older models. Garmin also provide a website where you can upload your data and get analysis, set goals and track your progress etc ( http://connect.garmin.com/features/). http://braiden.org/?p=62 suggests it's possible to use garmintools + some xslt to push this data from linux. If all you want is track logging, openstreetmap have a hardware guide ( http://wiki.openstreetmap.org/wiki/Hardware_Guide), which is the best listing of devices that work with Linux that I know of.

If you think you might come, please visit http://anyvite.com/ewaqa64bwu and sign up. == July SLUG Monthly Meeting == You can read the full version of this announcement at http://slug.org.au/node/116. When: 18.00 - 21.30, Friday, 31 July, 2009 We start at 18.30 but we ask that people arrive 15 minutes early so we can all get into the building and start on time. Please do not arrive before 18.00, as it may hinder business activities for our host! Appropriate signage and directions will be posted on the building. Where: Our venue for this meeting is Google, Level 5, 48 Pirrama Road, Pyrmont. It's across the road from Star City Casino. A map of the area can be found here[1], and public transit directions are at [2]. Appropriate signage and directions will be posted around the building. You will need to sign-in to enter the venue. This can be performed when you arrive, but to save time we recommend that you do so online beforehand at Anyvite[3]. If you are unsure, please sign up as a 'maybe'. This allows us to organise adequate meeting space and facilities. You do not need to create an account to indicate your attendance. General Talk Tom Worthington: Learning to lower costs and carbon emissions with ICT Tom designed the first globally accredited course on Green ICT and has been teaching it via the web since January 2009. The talk will discuss how ICT can be used to reduce greenhouse gas emissions 15% by 2020. Also outlined is how to use the web for running formal, university accredited courses using free open source software with open access content delivered to smartphones. The Istanbul public transport system also gets a mention. ;-) See Tom's Web site[4] for more information. Tom runs green IT courses at ANU and ACS. You can read the free open access version here. In-Depth Talk: Rob Collins: Massively parallel testing via Subunit Subunit [https://launchpad.net/subunit] is a streaming protocol for test results. I used it in bzr to parallelise the test suite and make effective use of multi-core machines (something python isn'tintrinsically good at), and to run tests in a massively parallel way via amazon ec2. Subunit is likely to be useful for anyone doing nontrivial automated testing, particularly when distributing or otherwise running the testsin a noninteractive fashion. SLUGlets General discussion and QA about Linux, free software and open source.

In the words of Agent 86, If only he had used his video skills for good instead of evil. :)) I've offered Ken to assist in editing the videos from the monthly meetings (and any others we put up). As editing, merging, transcoding etc is not that hard, I thought I'd also create an intro and outro for the videos, as well as add credits etc where necessary. This would give them a little more polish. So here are some pieces I've been working on. There are four which are similar. One each of white and black backgrounds with borders around the letters and one each of white and black with no borders around the letters. My favourite is the black with border - it makes the video stand out more. Each of these has moving images inside the letters. The video is from creative commons video and some I've downloaded from our site and others I've been given by Ken. The fifth is a mosaic of photos which dissolves into the slug icon with text at the bottom. The length of the videos is not indicative of what I'm proposing for our video, just to let people have a look and see what they would prefer.

Re: [SLUG] Scripting mystery
Searching for works from command line but not via cron shows that you're not alone :) Usually, this stems from the fact that cron doesn't execute your various shell initialisation scripts - ~/.profile, ~/.bashrc, ~/.bash_profile, ~/.login, etc. A common problem is thus that $PATH isn't set (when the script runs under cron) to what you expect (based on what you see when you're running it by hand). However, all sorts of other things could be different: your ~/.bash_profile might set a non-standard umask; or set up some aliases that don't exist when the script runs under cron. Changing the shebang line to #!/bin/sh -x will cause each line to be echoed; if you then change the cronjob to /var/log/cronlog or similar you should get some more information about what cron is actually running, and what the rsync commands are doing. A random guesses, aside from the things I've mentioned above: the shebang line stipulates /bin/sh; I'd bet you're not using /bin/sh as your shell. On some systems /bin/sh is bash; on other systems it's something different - maybe sh, maybe dash, maybe bash-in-sh-compatibility-mode. Another random guess: if the cronjob runs as a user who doesn't have 192.168.0.20 in their ~/.ssh/known_hosts file, ssh will ask questions about whether you really want to connect. It's possible that when you do it by hand you have a pre-populated ~/.ssh/known_hosts, but the cronjob runs as a different user and doesn't have that. On Sun, May 10, 2009 at 2:14 PM, Rick Phillips ri...@suntech.net.au wrote: Apologies for the HTML posting - it is necessary to get the command scripting to show more correctly. All of the commands in the script are one liners. I have a situation I am trying to deal with via automation .i.e.cron. The story to be brief is this - my boss is paranoid about security. A little time ago we ran an external server with an internal network connection controlled securely using iptables, very strong passwords and deny all except local ip addresses in hosts allow. In fact this group reviewed my security last year. There has never been a successful penetration but despite this, the boss demanded that I disconnect the server from the internal network so that it could only be accessed from outside. We are only talking about web access here. After an horrendous couple of months when everything slowed down to hell as our internal internet bandwidth is pretty much maxed out all of the time, he asked me to come up with a solution which allows the staff at home to access the server at night but during the working day, he wants absolute speed. He still will not allow the internal connection however. This server is on a separate dedicated internet connection BTW. We have a spare server so I have set this up on the internal network and have written some scripts which effectively shut down the internal network, connect to the external network and allow the external server to pull or push the data via the temporarily opened joint connection. It is a lot of work but it does work to a point. What is happening is that when I run the scripts via cron, the job does not complete properly i.e. the syncing is incomplete in both directions. When I invoke the scripts manually from the command line they do complete properly. The minor scripts work properly via cron - these are the ones which change permissions and create and delete some files and open and close the ports. The most crucial ones do not work properly and these are the pull/push scripts. One of these is below. The biggest sync job is the first one in the script which must transfer 11Gb data but when run via cron sends precisely 25Mb. As said earlier, when run from the CLI it performs correctly. It's as if the cron instance just races through the script and I can't understand why it should do this. I have resorted to putting full paths into the script for the commands. It is impractical (I think) to run this script as separate syncs as the completion time of the main one is hard to judge. This needs to be foolproof in case I am not there to intervene. #!/bin/sh /bin/touch /var/www/moodledata/1/maintenance.html ## Flag to make the site unavailable /bin/chown apache: /var/www/moodledata/1/maintenance.html ## Just changes the permissions /usr/bin/expect -c 'spawn /usr/bin/rsync -vrux /var/www/moodledata/ r...@192.168.0.20:/var/www/moodledata/ ; expect password ; send mypassword\n ; interact' ## This one invariable does not complete /usr/bin/expect -c 'spawn /usr/bin/rsync -vrux /var/www/html/moodle/ r...@192.168.0.20:/var/www/html/moodle/ ; expect password ; send mypassword ; interact' /usr/bin/expect -c 'spawn /usr/bin/rsync -vrux /var/lib/mysql/moodle/ r...@192.168.0.20:/var/lib/mysql/moodle/ ; expect password ; send mypassword ; interact' The inside server allows a root connection and the cron job is run as root as is the CLI job. The major sync jobs are run on the outside

Nothing non standard about my bash profile but on this system, both root and my own bash profiles are identical. Sorry, my ramblings weren't very clear The point is that cron doesn't load *anyone's* profile; it doesn't matter what's in roots, it will never be looked at. The usual problem is that even the standard profile includes path mappings that the cronjob doesn't get; but you seem to have allowed for that by explicitly defining paths. Changing the shebang line to #!/bin/sh -x will cause each line to be echoed; if you then change the cronjob to /var/log/cronlog or similar you should get some more information about what cron is actually running, and what the rsync commands are doing.

I have changed it to bash but won't know until tomorrow morning if it is going to behave.

It currently is running Mandriva Server 3 which is getting old and I am in the throws of setting up a new server using Centos 5.2. Most of the web based stuff that I serve is based on Joomla but one customer has had a professional web designer create a new site for him which I have uploaded and all is working just fine. I have never allowed FTP, SFTP nor SSH access to the server for security Recent versions of openssh (5.0 onwards at least, possibly some of the later 4.x series too) allow you to set up per-user chrooting; have an internal sftpd which can run in the chroot without you needing to do anything to set up the chroot; and allow you to stipulate that user X must run command Y Taken together, this make it fairly easy to give a user (or a group of users) SFTP access, with no possibility[1] of shell access; limited only to their 'homedir' (which can actually be any directory you specify, as long as they have the correct permissions - /var/www/username would work just as well.

Both are so brief as to look like summaries rather than detailed walkthroughs, but that's just a function of how little setup there is to do. To lock it down further, you can lock down their access to only certain IPs - via iptables, or via a Match block in sshd_config (or ideally, both). [1] no possibility - aside from, eg, bugs internal to openssh/sftpd that allow the remote user to run arbitrary code, etc. Compared to older ways of trying to force users to only have sftp capacity, this is a godsend. reasons (other than myself) but this customer wants to directly edit his new web site from time to time. I don't run C Panel (can't afford it) nor can I run ISPConfig which has some features missing such as mailing lists which a couple of clubs I host use. I am looking for suggestions as to what members might think would be an easy but secure way for this customer to do what he wants to do - make changes to his web site directly on the server. I run name based virtual domains and I guess I could set all other folders which other customers use with chmod 700 and perhaps set up his folder as 750 and make his username part of the apache group. I would then make his home area his web page folder but I am looking for a better way - if there is one. Would webdav be the ticket although I have never successfully set this up or is it just as easy for him to use an FTP client using SFTP to access his web root and make changes?

Re: [SLUG] Need a lesson in memory
In short: that's normal, and shouldn't cause your machine to be slow - unless it's starved of RAM, in which case the solution is to get more RAM, not to cache less. Here's some sample output from my machine right now: poll...@andromeda:~$ free total used free sharedbuffers cached Mem: 823512026884845546636 0 815620 697696 -/+ buffers/cache:11751687059952 Swap: 2097136 02097136 The values reported under buffers and cached represent files read from or written to disk, which the kernel is cached in RAM in case they're needed again soon. If you take the buffers and cached values from the first row and subtract them from the used value (or add them to the free value), you get the values on the second row, which are (usually) the more important figures. You haven't mentioned swap though - is your machine eating into swap? My machine isn't - hence the 0 in the used column on the third row. If your machine is chewing into swap, the slowness could be caused by the machine having to constantly swap things in and out of RAM. There's a slight chance you could fix this by tweaking the swappiness of your kernel - but more likely, you'll swap one kind of slowdown (applications swapping in/out) for another kind (commonly-used files having to be read from disk every time, rather than being cached in fast memory) The classic example of this is a memory-limited desktop machine running both GIMP and Firefox. Dumping buffers/cache means that both Gimp and Firefox run sluggishly, but you can swap between apps at will. Swapping out applications makes GIMP run faster while you're using it - but causes the whole system to freeze for a second when you swap to Firefox, and then freeze again when you swap back. http://kerneltrap.org/node/3000 has a lengthy discussion about the swappiness parameters (from the linux-kernel mailing list, back in 2004). In short, /proc/sys/vm/swappiness controls how much the kernel swaps - 0 means the kernel will avoid swapping at all costs and dump cached files instead; 100 means the kernel will swap out anything it can in favour of lots of caching. The best solution though is to get more RAM. It's cheap, and it makes everything faster. That is, assuming this is actually your problem (if this email is incoherent, it's because my morning coffee has had time to perk me up, but not enough time for me to actually be awake yet) On Fri, Feb 20, 2009 at 8:48 AM, Kyle k...@attitia.com wrote: Hi Slugger's It appears I need a lesson in Linux and memory management.

Re: [SLUG] Distro for fast web browsing on old machine.
It would be helpful to know more about what's causing the problems with the distros you've tried. Is it a runaway processing chewing CPU? Is it the browser itself chewing CPU? How is the RAM situation - is it full (and consequently spending a lot of time swapping)? If it is - how much is free before you start Firefox? How much is Firefox using?

Ideas? edit /etc/sudoers create a line along the lines of: username all=NOPASSWD: /bin/kppp This will allow username to run the command /bin/kppp as root without needing to enter a password. You could then put the insmod and the kppp into a single script, which would run without needing a password. Discovering whether or not this is needed, whether or not it's a good idea, and whether or not there are better ways to accomplish this are left as exercises for the reader.

Re: [SLUG] Wireless router with Optus broadband cable
Yes - as of hardware version 5 of the WRT54G, they switched to VXWorks as an OS instead of linux. This enabled them to halve the amount of memory needed, and thus make the unit cheaper. However, they were sensible enough to know that most of the reason why the original WRT54G was popular was the linux support, so at the same time the rebadged the version 4 WRT54G as the WRT54GL and continued selling that. http://en.wikipedia.org/wiki/WRT54G#WRT54GL has some of the detail.

Application-layer proxies are the only way I know of to achieve this. DNAT works at the transport layer; at that layer, the only addressing information you have is the source/destination IPs and source/destination ports. The information which you need to use to distinguish between the internal hosts is a few layers up - in SMTP to: headers or HTTP host: headers. Unfortunately, you're not going to get any of this data until, at the very earliest, the first packet after the TCP three-way handshake; there's no possible way to perform the DNAT earlier than that because you don't know what the internal destination is going to be. The only way to achieve what you're looking for (that I can think of anyway - I'd be thrilled to be proven wrong) is with an application layer proxy.
