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

Search and replace(insert) - can anyone help?

<table class="socialheader" width="100%" border="0"> <tr> <td width="85%" align="left" nowrap>The Three Sisters, Glen Coe</td> </tr> </table> I have over 2500 pages with the above HTML in ( the "Three Sisters, Glen Coe" bit is different in every file) and I want to add two lines so: <table class="socialheader" width="100%" border="0"> <tr> <td width="85%" align="left" nowrap>The Three Sisters, Glen Coe</td> <One new line here> <Another new line here> </tr> </table> The pair of lines to be inserted is identical in each case but the only unique identifier is the "class=socialheader". Is there any way I can do it with a script? -- Barry Samuels http://www.beenthere-donethat.org.uk The Unofficial Guide to Great Britain

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

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

ALUG library
by Wayne Stallwood 25 Oct '10

25 Oct '10

I am still looking to rid myself of having to store the ALUG library. The fact is that since being librarian (2003ish) we have lent exactly no books. Most of it is now horribly out of date...a long time ago I abandoned the magazines. There are a few newish titles I have added and a recent donation of "linux in a nutshell" from O'Reily. The online catalogue is offline due to the hosting it was on being broken. I have backups but it was pretty crufty anyway. More donations can be sought..but to get more out of O'Reily they were wanting us to do online and open access reviews and comments about the donated titles. I no longer have the time or the enthusiasm to do this. I see two potential futures. Somebody takes it over and tries to resurrect it by getting a book review section up on the wiki and therefore hopefully attracts more relevant donations..clears out the crud and tries to resolve the logistical issues of free book lending to remote members. or we disband it.... If this was decided then I would post a catalogue and members could claim anything they wanted to keep for themselves. After a time I would take whatever is left and donate to a charity shop or similar. Please can you respond and let me know your ideas...I don't want to go giving it away without approval from those that helped build the collection or if anyone sees a potential future for it. At the same time however it has long been a burden for me to store and I need the space in my study back...currently it consists of about 3 stackable boxes full of books. Many Thanks Wayne

Re: [ALUG] free or cheap web hosting

Thanks, guys. Turns out on investigation that 1and1 has a much cheaper basic package than I realized, at around 2.50 a month for the entry level one, but he seems most impressed with the daily.co.uk package. The year in advance is a pretty decent deal. Thanks. Peter

free or cheap web hosting
by Peter Alcibiades 23 Oct '10

23 Oct '10

A penniless artist asked me to suggest free or cheap web hosting. Obviously he will not have a lot of traffic, and what he wants to do is put up his pictures for view, but not particularly high res. So it does not have to have a lot of space. I don't know whether own domain is important or not. Might be nice. Any suggestions? I had thought of 1and1, which seems to do a basic package for around £120 a year including domain. But if there is anything anyone would recommend thats cheaper and still decent, the pennies would help. Peter
