Camcorders (Linux friendly, of course)
by Steve Fosdick 21 Dec '08

21 Dec '08

Does anyone have any experience of or recommendation for a camcorder? For me the top priority would be able to make backup copies of the video without resorting to proprietary software, i.e. it would need to record on media that be directly read under Linux or use a communication protocol for which there is a Linux implementation. It would also be good if the video/audio codecs used by the camcorder had a Linux implementation, at least for decoding, so that I could edit the video if I want to or watch it on the PC. Of course, if I can not play the video under Linux I would also want some way to be able to transfer it back to the camcorder for watching on the TV should the need arise. TiA, Steve.

HDD recovery
by Mark Rogers 19 Dec '08

19 Dec '08

I'm trying to recover data from a (Windows 2k) HDD belonging to my sister. I first tried with the drive in an IDE to USB adapter which wasn't recognised (the adapter was, the disk wasn't) which isn't good. So I'm now trying with the disk mounted in a PC. The BIOS can see the disk and correctly shows its manufacturer/serial/etc. I booted to an Ubuntu live CD and ran GParted, and it shows the disk as 18GB of unallocated space (which is the right capacity, although obviously I'd have prefered it to show an NTFS partition). fdisk cannot access the disk. I tried dd which gives a read/write error. The disk is spinning up OK and isn't noisy. Any suggestions? Professional data recovery could be considered but is probably too expensive. It's lost photos of my niece I'm trying to recover, amongst other things. Professional recovery is likely to be too expensive to justify unless it's under <£100 and I tend to assume anyone below that price isn't going to be doing anything I can't do myself with some Linux tools like scalpel, but if anyone knows otherwise I'd love to hear from you! -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

Understanding rsync
by Mark Rogers 19 Dec '08

19 Dec '08

I'm trying to sync a directory on my PC with a directory online, using the following command: rsync -avz `pwd` user@example.com:`pwd` In other words, sync the current local working directory with the same directory on the server. Before the sync, I have 12788 files locally and 11433 files remotely. After the sync, I still have the same number of files at each end. rsync is not giving me any errors so what am I missing? (If I expand `pwd` out to the full path I get the same results so that's not the problem. The path doesn't have any spaces.) -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

Gnome context menu integration
by Mark Rogers 19 Dec '08

19 Dec '08

I'm sure a suitable Google would help me here but I'm not sure what to search for; a few random attempts got me close but not close enough. I have to work a lot with XLS files which need converting to CSV files (using a tab separator). At the moment I do this using OOo which is overkill. I could do this from the commandline using htmldoc/xls2csv but that's not all that convenient in the GUI environment either. So what I would like to do is right-click the file in Nautilus and click a "convert to TSV" menu option that I set up to use xls2csv, taking blah.xls to create blah.csv. Where do I start? There's lots of similar stuff I'm used to from Windows (eg using the context menu to create/extract zip/etc files) although I wouldn't know how to do it on Windows either - I'd rely on the relevant apps setting that up for me. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

sshd configuration problem
by Chris G 16 Dec '08

16 Dec '08

By default I have sshd set up to disallow root logins, if I want to get to root from a remote login I login as myself (one password) and then su to root (another password). However I want to allow root login from one other system on the local LAN. To this end I added the following to the end of sshd_config:- PasswordAuthentication no AllowUsers root(a)192.168.1.7 However this, of course, prevents anyone logging in from anywhere except for root(a)192.168.1.7. How can I allow any non-root user from anywhere but root only from 192.168.1.7? -- Chris Green

LAN addresses in /etc/hosts
by Chris G 12 Dec '08

12 Dec '08

Having got dnsmasq working somewhate better (thank you Brett!) I now need some advice on what to put in /etc/hosts on the machine that is running dnsmasq. The machine's name on the local LAN is "isbd", to the outside world it is known as "home.isbd.net". It has a static IP address on the local LAN of 192.168.1.4. "As built" ubuntu puts "isbd" in the /etc/hosts file as follows:- 127.0.1.1 isbd However I need dnsmasq to tell other machines on the LAN that "isbd" is 192.168.1.4. Do I just remove the above line and add:- 192.168.1.4 isbd Is the "127.0.1.1 isbd" only necessary when isbd's address is obtained using DHCP and thus not fixed so it needs to point at localhost? -- Chris Green

I can't get dnsmasq to work at all, ideas please
by Chris G 12 Dec '08

12 Dec '08

I have installed dnsmasq on my xubuntu 8.10 system using the standard ubuntu apt-get which gives me version 2.45 of dnsmasq. It seems to have installed a reasonable default configuration and dnsmasq has been started up. However I can't get it to provide answers to any DNS requests. As I understand it dnsmasq should read the contents of /etc/hosts and give out local network IP addresses in response to DNS requests, only passing requests on the the external server(s) in /etc/resolv.conf if the address requested isn't a local one. I have dnsmasq running on 192.168.1.4 whose /etc/hosts has the following in it (after the standard default stuff):- # # # Local additions # 192.168.1.1 vigor 2820n 192.168.1.4 home.isbd.net isbd 84-45-228-40.no-dns-yet.enta.net chris.isbd.net 192.168.1.5 home 192.168.1.6 maxine 192.168.1.7 nas garage 192.168.1.44 hp7310 HPEDDBB7 HP000D9D068F7D 192.168.13.254 2wire BT2700HGV gateway.2wire.net I am attempting to use it from 192.168.1.7 which has no non-default additions to /etc/hosts and has the following in /etc/resolv.conf:- # Generated by NetworkManager 192.168.1.4 ... but if I do "host maxine" on 192.168.1.7 I just get:- ;; connection timed out; no servers could be reached Sending signals to dnsmasq produces the expected responses in syslog so it is running and working, signal 1 reports "read /etc/hosts - 17 addresses". So it appears to have some addresses to respond with but the other systems on the LAN don't seem to be able to talk to it. Any ideas what might be wrong, or ways to diagnose it? -- Chris Green

What FS might be on this CD?
by Ted.Harding＠manchester.ac.uk 12 Dec '08

12 Dec '08

Hi Folks, I have a CD which was burnt using Windows Media Player on Vista. It carries a couple of directories with many (mostly PDF) files. When accessed with Vista, its contents are visisble and the files can be accessed. However, Linux doesn't want to know! For example: # mount -t auto /dev/hdc /media/cdrom0 mount: block device /dev/hdc is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/hdc, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so and # dmesg | tail hdc: media error (bad sector): error=0x30 { LastFailedSense=0x03 } ide: failed opcode was: unknown ATAPI device hdc: Error: Medium error -- (Sense key=0x03) Unrecovered read error -- (asc=0x11, ascq=0x00) The failed "Read 10" packet command was: "28 00 00 05 7c 80 00 00 02 00 00 00 00 00 00 00 " end_request: I/O error, dev hdc, sector 1438208 Buffer I/O error on device hdc, logical block 179776 UDF-fs: No fileset found Any ideas?
