Re: [ALUG] weird problems

Ha! Weird problem, undid the machine to take a look at the innards, and noticed a slight rattling sound. Odd, but get distracted and take a look a the hard drive. This has a yellow sticker on it bearing the legend Drive 1, and someone has written in marker across it Windows 7. Interesting. Think about this for a while. This is after all a new custom built machine. Then move the machine around to see where the rattle might be coming from. It seems to come from the fan, which is a stock Intel fan and heat sink. Odder and odder. Waggle it a bit, and it comes up easily on one side! In short, three of the four securing pins are not secured into the main board, so presumably the fit of the heat sink is, well, dodgy. Oh dear. This might be the solution. In the meantime my friend lost his sense of humour and trashed all the previous partitions, well, hard to blame him. So here we go again.... Peter

weird problems
by Peter Alcibiades 04 Nov '10

04 Nov '10

How about this? Friend with a windows 7 installation. He tells me he was using skype and suddenly the system crashed after which Norton had vanished and several pictures went missing. System restore done by his current helper tried twice and failed to work. I told him to buy a new oem copy of windows (his last being of dubious provenance), have his helper partition the machine into two NTFS partitions and some free space for Linux, and reinstall. He did this, but was unable to reinstall, not sure why, so brought the machine over. I reinstalled Windows with no problem, and then proceeded to Debian. Well, there was a message about the fstab not being right because of an error involving the partition id. I didn't understand this, but proceeded. All goes well, we install grub, we reboot, and the windows install is nowhere to be found in the bootloader. After a long story, I put in PCLinux instead, and this goes in and works fine, grub picks up the windows install, we can boot from either linux or from windows, no problem. He goes home, sends me a couple emails showing windows at least works. I get this message: Email from Windows, printer driver, sound, flash player, microsoft security, Admin account for Windows, and it's all still working! This morning, sad message from another computer, he is down again. It will boot neither Linux nor Windows. Do you think this might be hardware? I wonder about trying memory diagnostics or hard drive verification program? I can restore the boot sector in windows, I can also take him to lilo, but will it last any better than the others? Or if not that, any other suggestions? Peter

Hi Barry, I made a slightly bigger test file from your input for testing. ===================================================================== <table class="socialheader" width="100%" border="0"> <tr> <td width="85%" align="left" nowrap>The Three Sisters, Glen Coe</td> </tr> </table> <table class="sociheader" width="100%" border="0"> <tr> <td width="85%" align="left" nowrap>This cannot be used</td> </tr> </table> <table class="socialheader" width="100%" border="0"> <tr> <td width="85%" align="left" nowrap>This is different each time</td> </tr> </table> <table class="socialhear" width="100%" border="0"> <tr> <td width="85%" align="left" nowrap>This is not usable</td> </tr> </table> ========================================================================= I think the perl script below (or some modification thereof) will do what you want. ===================================================== #! /usr/bin/perl use strict; open(INFILE, "<$ARGV[0]"); my $social_flag = 0; while(<INFILE>) { my $line=$_; chomp($line); if($line=~m/\<table class\=\"socialheader\"/) { $social_flag = 1; print("$line\n"); next; } if($line=~m/align\=\"left\"/ and $line=~m/width\=\"85\%\"/ and $line=~m/nowrap/ ) { if($social_flag) { print("$line\n"); print("One new line here\n"); print("Another new line here\n"); $social_flag = 0; } else { print("$line\n"); } } else { print("$line\n"); } } close(INFILE); ============================================================== Hope this helps.

Kerberos
by Richard Lewis 02 Nov '10

02 Nov '10

Hi ALUG, I've just tried to add a new user to a Debian unstable system I manage on a virtual server but have run up against some sort of authentication problem. As normal, I used adduser: $ sudo adduser interface Adding user `interface' ... Adding new group `interface' (1002) ... Adding new user `interface' (1002) with group `interface' ... Creating home directory `/home/interface' ... Copying files from `/etc/skel' ... But then it said this: Current Kerberos password: passwd: User not known to the underlying authentication module passwd: password unchanged Try again? [y/N] n Hitting n continued like this: Changing the user information for interface Enter the new value, or press ENTER for the default Full Name []: Interface2011 Room Number []: Work Phone []: Home Phone []: Other []: Is the information correct? [Y/n] y It seems I can't set a password for this user now: $ sudo su interface $ passwd Current Kerberos password: passwd: User not known to the underlying authentication module passwd: password unchanged I've heard of Kerberos and it all sounds great, but as far as I know, I don't "use it" (if that's the right expression) on this system. And I'd prefer just to use an ordinary UNIX password, because I just want it to work. I tried commenting out a line in /etc/pam.d/common-password: #password requisite pam_krb5.so minimum_uid=1000 password [success=1 default=ignore] pam_unix.so obscure use_authtok try_first_pass sha512 But I'm not whether: a) this has been effective; or b) would solve the problem anyway. Any ideas how to make it not try and use Kerberos?

Is there any way to 'ssh and cd'?
by Chris G 01 Nov '10

01 Nov '10

I'd like to set up some logins to various places around my LAN which not only ssh to the relevant place but also do a cd to a specific directory. Can anyone suggest a way to do this? By default if you give a command to ssh at the end of the line then it executes that command and then closes the connection - it only keeps the connection open if there is no command at the end. In addition doing a cd is even a bit more difficult because it's no use at all to execute it in a sub-shell. -- Chris Green

Thunderguts 2.# in Usenet mode
by Anthony Anson 30 Oct '10

Can anyone explain why, when I download headers there will be (say) 5 unread in a group, but on accessing it, a couple will disappear without trace? It happens most times the server is accessed. They haven't been eaten by the killfile - indeed, on most gruppen I don't have any filters. -- Tony Anson www.girolle.co.uk/

TV & Computer display screen
by ted.harding＠wlandres.net 29 Oct '10

29 Oct '10

Hi Folks, Once again picking the brains of the hardware-savvy amongst you! A friend of mine has asked me about what to get for a flat-screen which can double as TV and computer display screen. The size would need to be big enough to serve as a comfortable YV (so, I guess, at least 19/21 inch, probably larger). The intention is to plug the TV aerial into the back and use it as the TV, or plug the computer in and use it as the display. One computer is a not-too-recent laptop (no details held), but not very old. Dunno whether it has an S-video socket. Two other computers are rather old desktops dating back some 10 years (and with a Win of the vintage of Win 98 as OS, though I'm not certain of the exact version). Almost certainly no S-video, probably only standard monitor socket on video card. I'm clueless[*] about this sort of hardware question, so I'm asking for advice/comments! I guess the real question is whether a standard monitor socket can be connnectied to a TV (for suitable choice of TV); with associated question of whether large screen size may not work well with the computer. With thanks, Ted. [*] Not completely -- I have succeeded in connecting a recentish laptop to a TV using an adaptor cable from Maplin's, with S-video (1 connector) plus audio (2 connectors plus adptor to stero plug-in for computer's line-out socket) at the computer end, and a SCART plug at the other end for the TV. But this may be irrelevant for the present question! -------------------------------------------------------------------- E-Mail: (Ted Harding) <ted.harding(a)wlandres.net> Fax-to-email: +44 (0)870 094 0861 Date: 28-Oct-10 Time: 19:22:59 ------------------------------ XFMail ------------------------------

postgresql client question
by Jenny Hopkins 28 Oct '10

28 Oct '10

Hullo all, I've written a shell script that sends a line of insert sql to a postgresql database - or it's supposed to. If the script is run on the same host as the database, there is no problem. However, I want the sql to be sent and inserted from a client running ubuntu, to a debian server, without having to install the entire postgres package on the former. I read about postgresql-client-common being the tool for the job, duly installed it, but when it ran the sql "psql -h hostname -U username dbname < filename" it grumbled "Error: You must install at least one postgresql-client-<version> package". After googling some, I then tried sticking a default cluster in /etc/postgresql-common/user_clusters on the ubuntu client: "jenny jenny 8.3 CWMain dbname" but it seems to be looking at itself, rather than the host specified on the sql line: "Error: /etc/postgresql-common/user_clusters line 24: version 8.3 does not exist" The postgres version on the server is 8.3. Is there a different approach I can take - I feel I'm missing something incredibly obvious? I've always had postgresql installed on clients in the past and haven't come across this. Many thanks, Jenny
