Ubuntu questions
by Greg Thomas 22 Nov '07

22 Nov '07

I've just installed an Ubuntu box on an old PC (could do with an extra 256MB, but hopefully that will be sorted later today; thanks, Matt :) ) It strikes me that, unless I'm missing something, it's not quite as user friendly as I was led to believe; o There's no obvious way to get out system information; Device Manager will tell me it's a PIII, but not the speed. System Monitor will at least tell me the installed RAM, but again not the CPU speed. o "Power management" is a bit of a grandiose name, given that all it will do is turn off the PC or the monitor. No disk spin-down times, fan speed controls, etc. o There are two package managers (Update Manager and Synaptic Package Manager). The former, at least, tells me when there are updates available. I don't know yet if it will include extra packages installed by the latter (e.g. Apache WWW Server). Why two in the first place? o Disappointed that something as basic as NTP isn't installed by default. Even (spit) Windows has had this since NT4. So, is Ubuntu not quite as ready for the mainstream as I thought, or have I missed something? Greg

Surge I don't know. I can tell which router is right for /me/ - I currently use a Thomson Speedtouch (780WL). I like the fact that it provides both a web based GUI (for speed and ease of routine config) and a decent CLI for more in depth configuration. Thomson have a good guide to the CLI on-line at http://www.thomson-broadband.co.uk/codepages/content3.asp?c=7&ProductID=528 The router runs a linux kernel and busybox and unlike the BTHH (which is based on the Thomson) it isn't crippled. I also like D-LINK kit for home use. But if you really want the full flexibility of a linux firewall, then I'd go for IPcop. You /will/ need a separate box, but it has a very small footprint and will run on some pretty ancient kit (try 486 with 86Meg of RAM). Alternatively, if you really want to get your hands dirty, go for openwrt (mentioned by Adam in a different post above). Mick >What I really do care about is the hardcore access to the device.

Backup solutions for "not very linux" server destinations
by Chris G 21 Nov '07

21 Nov '07

I have just installed a 500Gb Network Server on my home network. It lives in the (very) detached garage so should be proof against even quite serious disasters to our house. However, although it runs a cut down Linux as its OS and thereby provides its services by Samba/CIFS it's not a very good or modern implementation and so it isn't easy to simply rsync files across to it. Using rsync (or the closely related rdiff-backup) results in lots of errors when the backup encounters symlinks, mixed case, etc. So I suspect I need a backup solution which packs up the files to be backed up into some sort of archive file and then just copies that file across to the server. Does anyone here use a backup solution of this sort and/or know any good ones? -- Chris Green

Secondary/Tertiary DNS to mirror hosted DNS (123-Reg)
by Mark Rogers 19 Nov '07

19 Nov '07

Anyone with 123-Reg hosted domains will probably be aware that their DNS died over the weekend. This ought not be possible, given the redundancy, but for about 24hrs nobody with domains hosted with 123-Reg (well nobody who uses their DNS anyway) will have had web/email. That includes me and several of my clients :-( Therefore I want to set up a DNS server on my own hosted server to act as (probably) a tertiary server (maybe secondary, not sure it matters for the sake of this question). In an ideal world I'd have a server which was fully (automatically) synced with 123-Reg's servers for all the domains I'm interested in. Given that I don't have any control over 123-Reg's servers I'm not sure how close I can get to that. I've also never set up DNS from scratch before (I've used various hosted DNS options which don't require me to think), but I think this would be a good time to learn more about DNS configuration. Not least because as a tertiary server it won't normally matter if I get it wrong :-) First question is pretty basic therefore: where do I start? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

ISP-relay SMTP question
by ted.harding＠nessie.mcc.ac.uk 15 Nov '07

15 Nov '07

Hi Folks, I'm hoping someone with the expertise can help me! In connection with trying to diagnose email delivery problems to a particular domain, I'd like to know the answer to the following. My email procedure is: 1. Compose the email "off-line" in my MUA (XFMail) 2. "Send" it -- so it goes in the outbox 3. Really send it (batch send) -- XFMail hands the outbox over to sendmail which then does SMTP with the mail server of my ISP (Zen). Up to this point, there is no problem; and receipt of a "check" Bcc: sent to me on an external email account via the ISP verifies that the ISP accepted the mail for delivery. And of course I usually have no problems with delivery of emails to their destinations by the ISP. Except for this one domain. Now the question. When my sendamil is doing its SMTP with Zen's mail server, the first substantive request it will make is mail from: <whatever.my.sendmail.uses> After the mail has been received by the ISP, the ISP's mail servers will try to initiate connections with the destination domain's mail server. Again, once a connnection is established, the first substantive request it will make will be of the form: mail from: <whatever.my.ISP.uses> My question is: What (if any) is the relationship between <whatever.my.sendmail.uses> and <whatever.my.ISP.uses> ?? Does <whatever.my.ISP.uses> take the email address from the "From:" header in the email? From the "envelope-from"? Or does it uses its own version, as in (e.g.): mailer-daemon(a)zen.co.uk Or what? One aspect of the background to this question is that, when I try myself to do a (test) manual SMTP dialogue with one of the remote domains mail servers, while I may well get through and successfully send the mail, on many other occasions I will get a response to "mail from:" on the lines of mail from: Ted.Harding(a)manchester.ac.uk 451 4.3.2 Please try again later which will be repeated indefinitely if I keep trying. So I'm wondering if it may be a negative response to the email address used in the "mail from:" request, or has some other reason. Since I don't know whether Zen's mail server would use the same (or similar) email address in its own "mail from:" request, I can't (as yet) link the delivery failures I get with my own SMTP dialogue with the delivery failures when Zen tries to forward my emails to the destination domain. [And, by the way, how should I interpret the error message 451 4.3.2 Please try again later ??] With thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <ted.harding(a)nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 15-Nov-07 Time: 11:36:23 ------------------------------ XFMail ------------------------------

Motherboard memory problem
by Chris G 15 Nov '07

15 Nov '07

I have just bought an extra 4Gb memory for my Abit AB9 Pro motherboard, I have plugged it in and it works fine (so I now have 6Gb) but I'm not convinced I understand the optimum way to install the memory. There are four memory slots numbered 1, 2, 3 and 4, they are laid out as two pairs, 1 and 2 close together and 3 and 4 close together. The manual is very ambiguous/confusing, it says:- To reach the optimum performance in dual-channel configurations, install identical DDR2 DIMM pairs for each channel. So does that mean a matched pair in both slots of channel A and a matched pair in both slots of channel B? That's not how the dealer had installed the existing memory and it isn't how their examples are either (see below). It's pretty definite that Channel A is slot 1 and slot 2, Channel B is slot 3 and slot 4, that at least is clear enough. However this is where it gets confusing, the sample layouts are for "Dual Channel Asymmetric" and "Dual Channel Symmetric", it doesn't say which is the best and they don't make a lot of sense. For example some "Dual Channel Asymmetric" layouts are:- Slot1 256Mb, Slot2 256Mb, Slot3 512Mb, Slot4 512Mb Slot1 256Mb, Slot2 256Mb, Slot3 256Mb, Slot4 512Mb Whereas a "Dual Channel Symmetric" examples are:- Slot1 512Mb, Slot2 empty, Slot3 512Mb, Slot4 empty Slot1 256Mb, Slot2 256Mb, Slot3 empty, Slot4 512Mb Slot1 256Mb, Slot2 512Mb, Slot3 256Mb, Slot4 512Mb Slots 1 and 3 are pink, slots 2 and 4 are red. I *suspect* that I have it right, as follows:- Slot1 1Gb, Slot2 2Gb, Slot3 1Gb, Slot4 2Gb (the dealer installed 1Gb were already in slots 1 and 3) but I'd really like to *know* that I have it right! -- Chris Green

One obvious point is DNS inefficiency. If the sending MTA gets back an answer to an MX query pointing to a CNAME it then has to query again to get the A record. If there is a CNAME chain (and there may well be) then there have to be multiple queries until the A record is reached. Check out the Bat book. Mick

More about sendmail sending to local machine
by Chris G 13 Nov '07

13 Nov '07

I'm beginning to think this is impossible! :-) I've been doing some Google searching about the file local-host-names, one hit suggested trying the following to see what sendmail views as local domains:- echo '$=w' | sendmail -bt ... and what does it return .... ADDRESS TEST MODE (ruleset 3 NOT automatically invoked) Enter <ruleset> <address> > home home.isbd.net localhost [192.168.1.1] isbd.net Which certainly looks as if sendmail thinks that home.isbd.net is the local machine. However when I tried using 'mail' to send a message from root to chris(a)home.isbd.net (I used 'mail' to ensure little else was involved) it *still* tries to send it out to the outside world. The entries in maillog are:- Nov 11 11:38:20 home sendmail[7883]: lABBcJ9h007883: from=root, size=64, class=0, nrcpts=1, msgid=<200711111138.lABBcJ9h007883(a)home.isbd.net>, relay=root@localhost Nov 11 11:38:20 home sendmail[7884]: lABBcKac007884: from=<root(a)home.isbd.net>, size=354, class=0, nrcpts=1, msgid=<200711111138.lABBcJ9h007883(a)home.isbd.net>, proto=ESMTP, daemon=MTA, relay=localhost.localdomain [127.0.0.1] Nov 11 11:38:20 home sendmail[7883]: lABBcJ9h007883: to=chris(a)home.isbd.net, ctladdr=root (0/0), delay=00:00:01, xdelay=00:00:00, mailer=relay, pri=30064, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (lABBcKac007884 Message accepted for delivery) Nov 11 11:40:20 home sendmail[7886]: lABBcKac007884: to=<chris(a)84-45-228-40.no-dns-yet.enta.net>, delay=00:02:00, xdelay=00:02:00, mailer=esmtp, pri=120354, relay=84-45-228-40.no-dns-yet.enta.net.

How to send mail locally, solved but I don't really understand why
by Chris G 11 Nov '07

11 Nov '07

Well I finally found a way to send mail to local recipients, quite by chance really. I have a POP3 mailbox set up at Gradwell.net to allow me to send mail to 'myself' on my home machine (I read just about all of my mail on a remote machine at Gradwell) which comes in useful occasionally when I want to send a file to my home Linux box. This is set up in my isbd.net on Gradwell so it's home(a)isbd.net. I just occasionally run mutt locally on my desktop machine and collect mail from this POP3 mailbox. So, I realised that one way around my problem of sending mail to myself on the desktop machine would be to put home(a)isbd.net as the alias for root mail in /etc/aliases. Before doing this I tried sending mail to home(a)isbd.net from my desktop machine, it failed with "Error sending message, child exited 67 (User unknown.).", huh? I then realised that this meant that sendmail was trying to send this *locally* and there's no user called 'home' on this machine. Euraka!!! If I send mail to chris(a)isbd.net on my desktop machine it gets sent to the local user chris and *not* to the place where it would get sent if it was sent from anywhere else on the internet (chris(a)isbd.net is one of my 'real' E-Mail addresses). So, problem solved, I can put:- root: chris(a)isbd.net at the end of /etc/aliases and all the root mail will get to me locally. Quite *why* it's like this is anybody's guess! :-) -- Chris Green

How to get mail to local destinations delivered?
by Chris G 11 Nov '07

11 Nov '07

I have a fairly default Fedora 7 installation, certainly the sendmail is just as it was installed. How do I get sendmail to deliver mail to local destinations? The system's hostname is home.isbd.net and it's connected to the Internet via a router. I have a CNAME set up at the hosting provider that hosts isbd.net to point at the static address of my ADSL connection. When I send mail from my system to a local address it gets the hostname added, thus mail gets sent to root(a)home.isbd.net, postmaster(a)home.isbd.net, chris(a)home.isbd.net, etc. All of this fails because sendmail attempts to connect to the SMTP port of home.isbd.net, which isn't possible because my router's firewall doesn't accept connections on port 25. I don't want to open up port 25 and it seems a bit silly anyway to send mail on such a long round trip. Is there any way I can tell sendmail that home.isbd.net is localhost (or 192.168.1.1)? I have an entry for home.isbd.net in my /etc/hosts file which is:- 192.168.1.1 home home.isbd.net but obviously sendmail is doing a DNS lookup for home.isbd.net which returns the 'external' IP address. -- Chris Green

Regex
by Ruth Bygrave 11 Nov '07

11 Nov '07

In a more-stupid-than-normal moment I ended up with a Text Edit document on my Mac with lots of capital I's in the middle of words. I tried 'check spelling' to see if it did an entire run of spell- checking through the document, but there was no dialog box. Tried to go through it in NeoOffice, which I'm not that familiar with, but NeoOffice bombed. Can somebody less brain-dead than I appear to be today come up with a bash script to pour the text into that does 'replace I not on word boundary with i'? (The infuriating thing is, I used to *know* this stuff, or at least where to look it up, but because I've been Abjuring Hackish Unixy Things since I was in mental hospital this summer, I don't even know where to start...) Also 'replace 'fI ind' with 'I find', because the reason I was messing about with I's in the first place was there's a timing error with my Alphasmart Neo keyboard and it has a tendency to transpose letters.

Samba question/problem
by Chris G 07 Nov '07

07 Nov '07

I have Samba installed and working on my Fedora system, it mostly does what I expect but one entry doesn't. My smb.conf file has:- # global section default service = default encrypt passwords = yes null passwords = yes workgroup = IBMPEERS nt acl support = no [snip] # # # ISBD, user is set to isbd to allow read/write # [isbd] comment = ISBD force user = isbd path = /home/isbd guest ok = yes writable = yes By my reading of the smb.conf manual page that should allow anyone in to access /home/isbd, it should make them act as the user 'isbd' and it should give write access. (Remember this is a home intranet, two users, who both want access to the ISBD files) In practice when connecting from XP I always seem to have to enter a valid password to get access. In general what's the easiest way to make Samba shares appear in XP 'automagically' without having to enter passwords etc.? -- Chris Green

Python question about reading files

I can't use an iterator because the file is read in variable length chunks whose length depends on context. -- Chris Green

BBC on amarok or whatever, how to?
by Peter Alcibiades 06 Nov '07

06 Nov '07

I'm seeking (for someone else) to get streaming BBC to play over some Linux player, don't really care what, on 64bit Debian. Once more cursing the day I ever installed 64 rather than 32bit, and on more than one machine, but that's another story. Amarok, attempting to tune into (for example) mms://wmlive-acl.bbc.co.uk/wms/radio1/radio1_nb_e1s1 gives the response Error loading media, there is no available decoder. I set up amarok in accordance with these instructions: http://www.linuxforums.org/forum/gaming-games-multimedia-entertainment/7934… and presumably having got to the point of trying to play, probably did it right. Assuming this is because there is no win codecs, I went to medubuntu and got the 32 bit ones. This was a large weighty package. They will not install being 32bit. OK, went back and got the 64 bit amd64 ones. This was a suspiciously small file, and one's fears were realized when the package installed and the message was unchanged. I have also downloaded Real Player, and made it executable, but now what to do with it? It too of course is 32bit and presumably that is why it will do zip when you try to start it. There is no problem downloading the mp3 files for previously broadcast programmes, and they play just fine (rhythmbox seems to be an acceptable interface for this). But what I'm really being asked to provide is streaming BBC internet radio. Anyone done it? Peter

How do people here manage updates (or not)?
by Chris G 06 Nov '07

06 Nov '07

Now that I have been running Fedora 7 for a while I'm beginning to see its strengths and weaknesses. One area that worries me slightly is what seems to be the 'normal' way of keeping it up to date which is to run 'yum update all' (or an equivalent) automatically at regular intervals. Most of the time this works fairly smoothly but every so often there is a hiccough and you see as a result hundreds of messages in the Fedora mailing lists saying "it's broken". For me one of the major disadvantages of this approach is that when the kernel gets updated (which is quite frequently) I have to recompile both my Nvidia display drivers and Vmware. The Vmware recompile can be a bit difficult as Vmware is only guaranteed to build against certain kernel versions and you often have to use third-party patches to get it to compile with more recent kernels. So I don't update all the time now, at least not the kernel. I'm wondering if there is a 'happy medium' somewhere between Slackware which was very conservative and stable (only went to a 2.6 kernal just recently) and Fedora which seems a bit frantically on the bleeding edge. Is there a distribution which offers pretty close to latest versions of everything when it releases but then just maintains things with only security updates and such until the next release? General requirements are:- Not too "GUI and Windows oriented", Fedora is definitely as far as I'd want to go in this direction. A reasonably good package management utility, Fedora's yum makes life a lot easier than Slackware. I run FVWM2 as my window manager so any distribution that makes it difficult to do this is out! Must run Vmware fairly smoothly, I think most probably will, Slackware was slightly messy because of its different initialisation script structure. Vmware is important to me as I need MS Access to run our company's accounts. Running them via Vmware on my desktop is just *so* much nicer than running on a separate machine that I'll never go back. It's all well backed up and, if the Linux/Vmware goes completely pear shaped I could easily enough just put them on a dedicated machine so absolute reliability of Vmware isn't necessary. -- Chris Green

Re: [ALUG] How should my hostname *really* be configured
by mbm 05 Nov '07

Chris > > I have a CNAME record in the zone file at the hosting provider that > hosts isbd.net so that home.isbd.net has the address > 84-45-228-40.no-dns-yet.enta.net which is my home machine (via ADSL). I'm assuming that enta.net give you a fixed IP address here. It certainly looks that way from their website. So the external world view of your "home.isbd.net" server will be OK and will resolve to the external address of your ADSL router. I also assume that you are either port forwarding 22 and 80 to your "home" machine or have it publicly available on a DMZ. > > So far so good, it all does basically what I want so that I can 'ssh > home.isbd.net' and log in to my home machine and http://home.isbd.net > in a browser gets to see the apache web pages on my home machine. > > > However I still don't seem to have the 'local' setup fully sorted, > i.e. how do I get things on my local intranet to work totally > correctly?

Ther apache error is probably not a DNS issue, but more likely caused by a configuration problem in apache2.conf (or httpd.conf). Try setting the ServerName directive to the FQDN "home.isbd.net". Apache will then use that and should stop complaining. > My home network is behind a router and most machines have static IP > addresses in the 192.168.1 range, the router is set up to allow ssh > and http through (with limitations). > > In my /etc/hosts file I have:- > > 127.0.0.1 localhost.localdomain localhost > ::1 localhost6.localdomain6 localhost6 > 192.168.1.1 home home.isbd.net > 192.168.1.5 garage > 192.168.1.10 chris > 192.168.1.40 netpr > 192.168.1.44 hp7310 HPEDDBB7 HP000D9D068F7D > 192.168.1.254 speedtouch > > Searching in google suggests that I need to add my proper hostname > (i.e. home.isbd.net) to the 127.0.0.1 line in /etc/hosts but that > sounds like it's incompatible with the 192.168.1.1 line. I recommend you don't alias your hostname to local loopback. Leave that to localhost. The 192.168.1.1 entry is fine. So long as all your hostfiles are in synch and your machines all look at local hosts files first (/etc/host.conf says "order hosts,bind") then they will all resolve "home.isbd.net" to 192.168.1.1. Alternatively you could run a local DNS server (possibly on your router) but for a small network that is probably more hassle than it is worth. > I want to end up in a situation where:- > > /bin/hostname returns 'home' (as opposed to home.isbd.net, so that > my prompts and window titles are sensible) > > home.isbd.net is a valid address on my local network and connects > to the linux server machine > > There are no complaints from apache (or others) at startup Just set each hostname locally to "foo" and ensure that /etc/hosts has alias entries for "foo.bar.net" as appropriate. Your example hosts file is fine, but you should have aliases for "garage.isbd.net", "chris.isbd.net" etc. to ensure proper resolution. HTH Mick

YUM: missing baseurl
by Yvonne Everett 05 Nov '07

05 Nov '07

I've just installed Fedora 6 and am having problems getting YUM and Software Updater to work properly. For instance, the extract below shows the "Error: Cannot find a valid baseurl for repo: core" error which is exactly the same error I get with Software Updated: [root@ukl20943l etc]# su -c 'yum grouplist' Loading "installonlyn" plugin Setting up Group Process Setting up repositories Could not retrieve mirrorlist [url]http://mirrors.fedoraproject.org/mirrorlist?repo=core-6&arch=i386[/url] error was [Errno 4] IOError: <urlopen error (-2, 'Name or service not known')> Error: Cannot find a valid baseurl for repo: core Any ideas anyone?

Boot question
by Chris G 05 Nov '07

05 Nov '07

My Fedora system has two (identical, but that doesn't matter) disk drives. Fedora is installed on /dev/sdb which uses LVM. Currently /dev/sda is partitioned the 'old fashioned' way. Now that I'm happy with the Fedora installation I want to tidy things up and use LVM for /dev/sda as well. Backing up and copying the data across is straightforward enough, I can cope with that. I have enough space that I can empty /dev/sda completely and partition it from scratch. However what worries me slightly is that there is presumably an MBR (that's what DOS used to call it) on /dev/sda which the BIOS goes to when the system is powered up. If I repartition /dev/sda will I lose this boot record? How does this get created in the Linux way of doing things? -- Chris Green

Re: [ALUG] How do people here manage updates (or not)?
by Bev Nicolson 05 Nov '07

FWIW.(Maybe not much but anyway...) Yes, it would be helpful if the Ubuntu update dialogue box gave more information about what was being fixed (when there is something to fix.) Mildly ironic given how user friendly it is. For relative newbie like myself the tech speak is not helpful so unless it actually looks useful I don't install it. On the other hand, most of the time you don't have to faff about configuring anything as it does it for you, although there are exceptions. I have had to venture into apt (with assistance) to get a program I wanted installed.
