Running vnc server on startup
by John Woodard 12 Sep '12

12 Sep '12

I want to run a vnc server on startup as a user rather than root and seek opinion to where the best place to put the command tightvncserver :1 -geometry 1280x1024 -depth 16 -pixelformat rgb565 etc/rc.local cron job? Not sure here really if it needs to be before login so thought it prudent to run as a user. Cheers, BJ

Anyone know about and/or use libgda (gnome DB library)?
by Chris Green 05 Sep '12

05 Sep '12

While searching for ways to access databases I have hit upon libgda which is the Gnome generic DB access library. What has attracted me specifically is the gridWidget which appears to give me exactly the sort of interface to a DB table that I have been after for quite a while. (See http://www.gnome-db.org/ScreenShots at the bottom). Does anyone here have any experience with libgda? -- Chris Green

It's possible to access the built-in modem capability on a GSII: http://forum.xda-developers.com/showthread.php?t=1471241 ..but not simple unless your phone provider includes host drivers (which it seems some do). Once you have the right modem device exposed, connecting it into PC Anywhere should be a breeze :) Or you can look at soft modems like SpanDSP: http://www.soft-switch.org/spandsp_faq/index.html http://www.soft-switch.org/spandsp-modules.html with the audio paths physically connected through your mobile from the sound card, but that seems a bit silly when the GSM baseband chipset can already provide what you want, if the manufacturer will let you use it.

How do I decide which printer driver to use in CUPS?
by Chris Green 04 Sep '12

04 Sep '12

I recently found that my printers were no longer working with one particular application (glabels). The error message from CUPS was "/usr/lib/cups/filter/hpcups failed" and a bit of Googling suggested that changing the printer driver selected in CUPS might fix the error.... and it did. I'm using the hpijs driver now instead of the hpcups driver. However it raises the question of how one decide which of many drivers available for a given printer one should select. For my HP1320 there's quite a lot to choose from:- HP Laserjet 1320 - CUPS+Gutenprint v5.2.8-pre1 (en) HP Laserjet 1320 Foomatic/Postscript (en) HP Laserjet 1320 Foomatic/pxlmono (recommended) (en) HP Laserjet 1320 hpijs 3.12.12 (en) HP Laserjet 1320 Series hpijs 3.12.12 pcl3, (en) HP Laserjet 1320 Series pcl3, hpcups 3.12.12 (en) HP Laserjet 1320 Series Postscript (recommended) (en) HP Laserjet 1320 Series Postscript (recommended) (en) HP Laserjet 1320 Series Postscript (recommended) (en) HP Laserjet 1320 hpcups 3.12.12 (en) ..., and yes, the Postscript one is repeated three times with no visible differences. So how is anyone supposed to decide which driver to use, I've not found any useful guidance anywhere. -- Chris Green

Using Android phone as dial-up modem
by Mark Rogers 29 Aug '12

29 Aug '12

Situation: PC running pcAnywhere, accessible via dial-up (you know that thing we used to use before broadband? :-) At present I have to be sat in my office (or somewhere with a phone line), using a laptop with a modem in it, to dial in to site (the site does not have Internet access). Can I use my Android mobile (Galaxy SII) as a traditional modem, eg via USB connection to PC? PC would ideally be Linux but I have pcAnywhere installed on both.

Samba usershares, symlinks, etc
by Mark Rogers 27 Aug '12

27 Aug '12

If I create a Samba share (eg directly in /etc/samba/smb.conf) I can enable following of symlinks (for just that share) with: follow symlinks = yes wide links = yes unix extensions = no When instead added to a usershare (ie in /var/lib/samba/usershares/myshare) this doesn't seem to work. Indeed, these files seem very "fussy"; just moving lines around or leaving lines commented out (with # or ;) seems to break the share completely. However I can't find them documented anywhere (nor indeed can I find usershare_acl properly documented anywhere). So: Is there a way to have a usershare with the ability to follow symlinks (without globally enabling them, which is what I've done so far)? Is there some documentation I'm missing that explains how these work? I can see why allowing users to enable that functionality may not be wanted, but on the other hand having to enable it globally doesn't seem like the best alternative. Should I just add my share to smb.conf and be done with it?

Attempt to use openvpn client as proxy server
by Jenny Hopkins 26 Aug '12

26 Aug '12

Hullo alug, I've got a computer here at home running debian that gets packages from a remote repository running behind a firewall at work using an openvpn connection. Local address is 192.168.10.6, remote webserver is known as repo.tcl.office. Remote nameserver is 192.168.10.10. Openvpn uses a tunnel of 12.3.3.0. I have a second computer on my internal network, address assigned as 192.168.1.whatever by the dhcp server (192.168.1.2) that i would very much like to be able to access this repository. At the moment all the second computer (a balloon-type board) knows is that it is on the network 192.168.1.0 and that its nameserver is 192.168.1.2...not much use to me at all, especially as the nameserver is not on the openvpn and has no idea about tcl.office. I had a try at assigning a static address on the 12.3.3.0 network to no avail, it couldn't ping the computer here on its tun 12.3.3.6 address. Adding various addresses to /etc/resolv.conf on the balloon make no difference. Is this an impossible mission, or are there any tricks and tools i can be using to make this happen? Running openvpn on the balloon is not an option, alas. Hints gratefully received. Thanks, Jenny

Screen resolution stuck
by Bev Nicolson 23 Aug '12

23 Aug '12

Screen resolution is resolutely stuck at 1024 x 768. Attempting it increase this or decrease it results either in it going awol (higher) or impractically large to deal with (lower). I can't do anything with the auto button the monitor. >From xrandr (I have been googling) : Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192 VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 304mm x 228mm 1280x800 59.8 1280x768 59.9 1024x768 75.1 75.0 70.1* 60.0 832x624 74.6 800x600 72.2 75.0 70.0 60.3 56.2 848x480 60.0 640x480 75.0 72.8 72.8 66.7 60.0 59.9 720x400 70.1 So, people, does this mean a new/another monitor might be an idea?

Android updates for cheap tablet
by Mark Rogers 20 Aug '12

20 Aug '12

I have a cheap Android tablet, branded Synapse, I think it's this model although I paid nothing like that for it: http://www.dee-sign.co.uk/products/synapse-tablet-top-spec What are my options for playing with Android versions? I'd like to experiment with (eg) CyanogenMod but haven't done it before; I was thinking it better to risk my cheapo tablet than my Galaxy SII but on the other hand at least the GS2 has been well tested... I believe the tablet is just the same as any number of cheap imported tablets and I don't want it to be stuck on the version it shipped with (albeit that it came with ICS). -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Keyboard and mouse 'crash'
by Bev Nicolson 19 Aug '12

19 Aug '12

Every so often (not too often happily) both keyboard and mouse will stop functioning. It seems to happen most often when I plug a camera or MP3 player in. The only way to get them going again is to switch everything off. (If I touch the off button it will shut down in 60 seconds from the shut down dialogue box.) What I'm wondering is, has anyone here come across this problem and is there another, more permanent, solution to it? I would add that I've never had to install any drivers for any such devices, so I'm pretty confident that's not the issue. [Unbuntu 11.04.] Bev.

Wanted - algorithm for bufferless search for a pattern in a stream
by Chris Green 08 Aug '12

08 Aug '12

I can see how to do this in principle but I can't iron out the details and I'm sure there must be some ready made code for doing it 'out there' on the internet. It's just rather difficult to come up with search terms when I don't know what to call it. To explain in detail I want to search for a (constant) string in a byte stream that I can't rewind and I don't want to use any significant buffer space (the constant string I'm looking for is quite long). So, obviously one reads a byte at a time from the stream to see if it matches the first character of the constant string, if that matches one moves on to the second, etc. When the whole string has been matched then it's found - so far so good. However, when a character *doesn't* match one can't go back up the input stream, *but* we know the previous characters as they're the ones in the constant string that we have matched so far. Thus we can 'wind back' by using the constant string for the number of characters that did match and then continue down the stream. If anyone can follow that rubbish explanation then could they possibly tell me what the algorithm is called and/or point me at some sample code? -- Chris Green

Forcing "Sender:" in exim4
by Ted.Harding＠wlandres.net 05 Aug '12

05 Aug '12

Greetings All! I have just (!!! -- after about 4 years ... !!!) that in my Debian Etch setup 'sendmail' is aliased to 'exim4': ls -l `which sendmail` /usr/sbin/sendmail -> exim4 My mailer (MUA) setup presumes sendmail. I have configured the MUA so that, in the headers for outgoing mail, I have set: Sender: ted.harding@wlandres (same as my "From:" and "Reply-To:" addresses). That is how the header appears while the message is still in the "outbox" folder. However, when I send the mail out, it seems that exim4 changes the "Sender:" address to "ted@deb", "deb" being the name of my machine on my home LAN (as set in /etc/hosts), and "ted" being the user. As a result, when the mail is received outside my LAN, the receiving host sees the header: Sender: ted@deb instead of what I want it to be! This sometimes results in rejection when the receiving host does not recognise the sender domain. Now, while I know my way round sendmail itself, I find I am disorientated by trying to make out how to customise exim4 configuration. (I've tried reading the man pages). What I want to do is ensure that exim4 (aliased as 'sendmail') either does not change the "Sender:" header as it is while still in the outbox, or else sets it anyway to Sender: ted.harding(a)wlandres.net And it could also be useful, though not essential, if, should I happen to mail as a different user on the same machine, e.g. "efh", it could preserve the domain and insert the user, e.g. Sender: efh(a)wlandres.net My mind is blank about how to set about configuting exim4, so I need very basic instructions (preferably with outline explanation). Maybe a configuration file (where and how?) change, or a command line option to exim4 (the latter is probably simpler for me, since I can enter such options in my MUA setup). With thanks!

LAN traffic sniffing/monitoring - good tools and methods - help wanted
by Chris Green 31 Jul '12

31 Jul '12

I want somehow (if it's possible) to monitor the packets going into and out of one ethernet address/MAC address on my LAN. I think it's currently plugged into a port on my 8-port Gigabit switch but I'm not absolutely sure of that. The LAN comprises a Draytek Vigor ADSL router talking to the outside world and a Linksys 8-port Gigabit router with most of my LAN systems plugged into that. I think a couple of the four ports on the ADSL router may be in use in addition to the one that connects to the 8-Port Gigabit switch. Is there any 'easy' way to monitor all traffic to/from one specific IP address on the LAN from my desktop computer or will the switches on the LAN prevent it seeing most of the traffic? Actually even being able to see all traffic between my desktop and the device I'm interested in would probably be sufficient as 'lack of traffic' might well be enough to tell me what I want to know. So what are the best/easiest packet sniffers to run on a desktop machine that would allow me to 'see' all traffic to/from a specific IP address? -- Chris Green

Xen and OOM killer
by Richard Lewis 30 Jul '12

30 Jul '12

Hi ALUG, I've been managing a Xen hypervisor for about nine months now and occasionally I get problems with DomUs running out of memory. The clients are all students and most of them are running WordPress blogs. The instances of OOM errors I've seen seem to be related to Apache and students serving up large image files. I'm thinking that this shouldn't really be happening; serving up a few ~1MB files shouldn't really be causing Apache to make the OS exhaust *all* available memory, should it? Even if it were servicing several requests simultaneously. Some details: * The host is a Dell PowerEdge x86_64 system with 32 GB RAM * The host OS is Debian 6.0 * We're running Xen 4.0.1 from Debian * The guests all run Debian 6.0 * Each guest has 15 GB of storage, 512 MB RAM, and 1 GB of swap * We currently have ~40 guests running Below is some console output from a DomU that suffered this problem earlier today. You can see that the OOM killer killed Apache. And I'm guessing it killed sshd too as I couldn't connect to the guest. I couldn't find any errors in Xen's logs. Any thoughts on what might be going on here? And come September we'll have a short window in which we could alter out setup. Any suggestions for better ways of providing virtual machines? Perhaps alternatives hypervisors? Or some mechanism other than hypervisors?

OT Maths Jam
by Steve Engledow 26 Jul '12

26 Jul '12

Hi folks, Would anyone be interested in a Norwich maths jam? See http://www.mathsjam.com/ for (fairly vague) details or check the twitter account (@MathsJam). tl;dr: We get together in a pub on the second-to-last tuesday of the month and be geeky. I know, it sounds like the pubmeet; but this time we be geeky about mathsy things! I reckon there ought to be enough maths geeks among the linux geeks for this to be relevant :) Steve
