hexdump formatting
by Mark Rogers 23 Nov '10

23 Nov '10

Has anyone here got any experience of hexdump output formatting? If I use hexdump -C I get: $hexdump -C -n32 /usr/bin/lsof 00000000 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00 |.ELF............| 00000010 02 00 03 00 01 00 00 00 60 97 04 08 34 00 00 00 |........`...4...| 00000020 What I want to do is extend the number of bytes per line to 32, but as there isn't a format for it that means using the horribly complicated -e option. I have got as far as: $ hexdump -n 32 -e '"%04.4_ao: " 16/1 "%02X " " " 16/1 "%02X " " " "xx" "\n"' /usr/bin/lsof 0000: 7F 45 4C 46 01 01 01 00 00 00 00 00 00 00 00 00 02 00 03 00 01 00 00 00 60 97 04 08 34 00 00 00 xx .. but haven't worked out how to insert the ascii values in place of "xx". -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Is there any way to run an rsync daemon/server on-demand as a non-privileged user?
by Chris G 23 Nov '10

23 Nov '10

Is there any way to do the equivalent of running rsync from an entry in inetd.conf that can be done by a non-provileged user? I want to run rsync from cron to backup files to a couple of places where I have shell logins (but not the privilege to make additions to inetd.conf). I suppose I could just run rsync in daemon mode using a cron job on the remote system (and kill it later) at the right time but that seems a little crude. -- Chris Green

An odd bluetooth problem
by Barry Samuels 22 Nov '10

22 Nov '10

I have just got Bluetooth working on my Thinkpad (Debian Testing/Squeeze) and it will pair with my Android 'phone but the signal keeps fluctuating. The link quality between 100% and -1%, the strength between 58% and -1 and it does this at around 2-5 second intervals. It does it even when the 'phone is next to the laptop. Can anyone suggest a reason for this? -- Barry Samuels http://www.beenthere-donethat.org.uk The Unofficial Guide to Great Britain

Well I don't know about you, but I'm convinced. Does this whitening kit run on linux though?

HDD errors
by Mark Rogers 19 Nov '10

19 Nov '10

I have a hard disk connected via a IDE/USB convertor. I was asked to look at the disk because of issues, and with a combination of tools (surprisingly mount and cp did most of what I needed!) have managed to recover most of his files (well the ones that matter anyway). However, I'm getting lots of the following in /var/log/messages: Nov 11 10:44:28 user-desktop kernel: [268615.430217] sd 10:0:0:0: [sdb] Unhandled sense code Nov 11 10:44:28 user-desktop kernel: [268615.430221] sd 10:0:0:0: [sdb] Result: hostbyte=DID_ERROR driverbyte=DRIVER_SENSE Nov 11 10:44:28 user-desktop kernel: [268615.430225] sd 10:0:0:0: [sdb] Sense Key : Hardware Error [current] Nov 11 10:44:28 user-desktop kernel: [268615.430230] sd 10:0:0:0: [sdb] Add. Sense: No additional sense information Nov 11 10:44:28 user-desktop kernel: [268615.430234] sd 10:0:0:0: [sdb] CDB: Read(10): 28 00 01 00 95 a0 00 00 08 00 Nov 11 10:44:28 user-desktop kernel: [268615.430248] __ratelimit: 41 callbacks suppressed .. and I was just curious to learn what they were telling me about what was wrong with the drive? I've Googled for some of the key phrases but don't seem to get a clear picture. I've seen references to Sense Key etc before with problems in the past (often USB thumb drives) so I figured a little extra knowledge might be no bad thing! -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Is there a fairly easy way to allow two users to write to the same hierarchy of files?
by Chris G 19 Nov '10

19 Nov '10

I want to enable two users to write to a specific hiearchy of files and I really can't see an easy way to do it. To be specific I have a hierarchy of files making up the data files of a wiki which I (mostly) edit directly but also need to be able to edit in the normal wiki fashion. Thus they need to be writeable by the apache2 process (which is user www-data) and directly by the user (which is me, user chris). Can anyone suggest a way to allow these to be writeable by both users? When a user creates a new file it must be editable by the other user as well so simply creating a common group to which both users belong won't work as, in general, the umask won't give files user write permission. -- Chris Green

Snapshots
by Chris Walker 19 Nov '10

19 Nov '10

Is it possible to take a snapshot of a running system rather in the way it's possible to do in things like VirtualBox? I'm thinking of installing some software but am not sure that once installed, I will be able to back it out with leaving files everywhere. Hence the idea of a snapshot. -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:cdw_alug@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

A customer has asked us to look at setting up a hosted sharepoint server for them. What are the best FOSS alternatives I should look at to give them some options? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

SBCs that run Linux - someone mentioned some a while ago
by Chris G 18 Nov '10

18 Nov '10

A while a go when we were discussing low-powered backup solutions someone here mentioned a couple of Linux based SBCs (Single Board Computers). At the time I was looking for something somewhat different but now I think I might have a use for such a device. Can someone point me in the right direction (the mail list archive isn't searchable so doesn't help much as I haven't a clue how long ago it was). -- Chris Green

Mostly OT: Kindle 3G
by Mark Rogers 18 Nov '10

18 Nov '10

There seem to be some Kindle fans here? £150 for the Kindle 3G seems like a good deal. I'm just looking for someone to persuade me to part with the cash! Any experiences with the "experimental" web browser? The relevant bit to this list: Any PC interaction I have with it will be from my Linux (Ubuntu) box. Any reason to have any concerns? I've never owned an eBook but I gigure something like Calibre should allow me to convert between ebook formats (the wife is concerned she'll buy an ebook from Waterstones that she can't use on it, for example; my concern is more about keeping her off MY Kindle in the first place!) -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG
