mysql 'forms' data entry designer
by Chris Green 08 Nov '04

08 Nov '04

My migration of my Access databases to mysql has started. I've got mysql, PHP and apache up and running and I've imported the data from my Access database. I can see it all in phpMyAdmin, most impressive! Now I need to be able to design/build replacements for the Access data input forms and the Access reports. Starting at the input end (seems reasonable!), has anyone got any recommendations for designing input forms for mysql databases? Searching Google isn't very helpful because as soon as you enter 'mysql forms PHP' (with or without the 'PHP' actually) you get zillions of hits on HTML forms for entering data via PHP into a mysql database. The problem is that this gives a rather backwards approach which assumes a 'typical' HTML form and that's not what I want really. For data entry it doesn't really even have to be a web form. What I'm after is essentially a view of my table with some calculations/filters between data entry and the database. I.e. when the 'form' is opened it loads up the whole database table and presents it on screen in tabular fashion. I can edit existing entries simply by moving to them and changing them, I can add entries at the end. Most fields simply get inserted unchanged in the database as I type them but some fields are automatically calculated and inserted when I enter/change other fields in the same row. This is what I've done in Access and I want to do something similar for the mysql database if I can, preferably with some sort of tool to help me! It's the sort of thing Oracle Forms does too. Surely someone must be doing it for mysql. The phpMyAdmin 'Browse' window looks somewhat like what I'm after but I need to be able to edit the data in place (I.e. move to the field and change it), add rows at the end and have 'auto calculated' values. -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice, that which can be explained by incompetence."

mysql users, I still seem to be a bit confused
by Chris Green 08 Nov '04

08 Nov '04

Well I have just about everything working now. I've managed to install apache2 and PHP5 (I don't quite understand what I did wrong the first time but going back to PHP4 and then to PHP5 again got it working). I've also installed phpMyAdmin and that's working fine too. However I still can't get ordinary users to work the way I expect. I'm using phpMyAdmin to do all this now. I deleted all the entries for user 'chris' and then added a new user 'chris' with host set to 'Any host', with password set to 'No password' and with all privileges set. This appears to work OK, phpMyadmin says I have a user as follows:- chris % No ALL PRIVILEGES Yes Edit (No is 'Password' and Yes is 'Grant') However if I then say 'mysql -uchris' and try 'use fred' I still get:- ERROR 1044: Access denied for user: '@localhost' to database 'fred' If, on the other hand, I do exactly as above except I set host to 'Local' then user chris works as expected. Something is certainly awry somewhere, it may be my understanding but at the very least things are not quite how one would expect from what one is being told. Is there some security thing that refuses to allow an 'Any host' user to have lots of privileges? No, I've tried creating a user with few privileges and 'Any Host' and they get the 'Access denied...' error too. It seems to me that the 'Any Host' doesn't work. -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice, that which can be explained by incompetence."

Anyone got a spare monitor / swap shop wiki page
by Joe Button 08 Nov '04

08 Nov '04

Hi. Does anyone else think it might be worth making a wiki page with a list of kit people have available? If people think it's a good idea I'll start one. Which is my way of introducting the cheeky question: Does anyone have a spare monitor they could sell me cheap? Mine died a while ago and I'd rather not buy a brand new one due to a combination of environmental concern and meanness. They seem to go pretty cheaply on ebay but I'd like to avoid the postage cost if possible. Also, can anyone recommend something to do with my old one? As far as I can tell no-one wants to repair it. Cheers, Joe

lastlog puzzle
by Ted.Harding＠nessie.mcc.ac.uk 07 Nov '04

07 Nov '04

Hi Folks, On one (A) of my 3 running machines, I noticed that 'ls -ls' on /var/log shows: A: 44 -r-------- 1 root root 19136220 Oct 30 10:52 lastlog which is inconsistent: 44K according to $1, but 19136220 bytes (19MB) according to $6. The latter is enormous! However, it seems that it has some validity, since # cat lastlog | wc -c 19136220 gives the same result, here obtained by byte-counting the output of 'cat'. This first got me wondering if the lastlog file or its inode contents were corrupted. (For reference below: I don't have a file /var/log/faillog on this particular machine, A). Interestingly, however, when I look at 'ls -ls' for my two other machines (B & C), I get B: 3 -rw------- 1 root root 12216 Nov 6 15:32 faillog 3 -rw-r--r-- 1 root root 16128 Nov 6 15:32 lastlog C: 8 -rw------- 1 root root 12072 Nov 4 13:17 faillog 16 -rw-r--r-- 1 root tty 146876 Nov 4 13:17 lastlog and for both machines, and also for both 'faillog' and 'lastlog', I see the same sort of discrepancy between $1 (size in KB) and $6 (size in bytes), the latter being distinctly too big compared with the former. I do not see this discrepancy for any other files in /var/log, on any of the three machines. This suggests that there's something a bit weird about 'lastlog' and 'faillog' as files, and that this is deliberate! And I'm wondering how on earth a 19MB lastlog file could arise (this machine, A, has been in use for a shorter time (about 1 year) than C (about 3.5 years) and much shorter than B (about 7 years); yet the sizes of 'lastlog' are in the reverse order!) The output of the 'lastlog' *command* in all cases is just a few dozen lines; but, again interestingly, doing it on machine (A) (the one with the 19MB lastlog) induces semi-paralysis and much swapping for a while. I'm puzzled! Comments welcome.

linux laptops
by Syd Hancock 07 Nov '04

07 Nov '04

(Sorry it's not threaded but only reading via online archives at present). The HP offering was disappointing. Very half-hearted effort especially not having the wi-fi configured. One suggestion: get an IBM Thinkpad from ebay and install a mainstream distro. The T series is good (I use a T23) and I have heard good things about the more recent X series as well. Good build quality. Thinkpads are sturdy. Three year warranty so it is easy to get one with a long warranty period remaining - mine came with 2.5 years remaining. Good support under linux with all mainstream distros - I use Mandrake 10.0 Official (although there is a gotcha with the X-windows config that you need to know about before installing). A linux-thinkpads mailing list and plenty of support and advice can be found via google etc. Lots of support for on IBM websites including linux-specific info. Did I say good build quality? :-) I added a wi-fi card and a second battery which swaps with the DVD/CD-R. It is an excellent general-purpose machine. ACPI is apparently problematic with recent 2.6.x kernels. I use APM instead and it works well. HTH Syd

Trying to install apache2 and PHP5 on slackware9.1
by Chris Green 07 Nov '04

07 Nov '04

I'm trying (as per the subject line) to install apache2 and PHP5 on slackware 9.1. I've uninstalled PHP4 and apache1.3. I've installed the apache2 and PHP5 .tgz packages. I've installed the extra library dependencies that apache2 needs. Now I get the following error when I try and start apache:- Syntax error on line 8 of /etc/apache2/mod_php.conf: Invalid command 'AddType', perhaps mis-spelled or defined by a module not included in the server configuration All seems in order to me. There is a line above the line 8 of mod_php.conf which loads the PHP5 library, i.e.:- LoadModule php5_module lib/apache2/libphp5.so No errors are reported for this line. All the lines were produced by script so typos are unlikely. Are there any old libraries in slackware 9.1 that may need updating to get apache2 to work? (I.e. libraries that aren't missing but are too old). Any other ideas? -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice, that which can be explained by incompetence."

Mozilla vs Firefox + Thunderbird
by Ted.Harding＠nessie.mcc.ac.uk 06 Nov '04

06 Nov '04

Hi Folks, Some questions about Mozilla vs Firefox & Thunderbird. Mozilla is an integrated web software suite: browser, mail client, Web page (HTML) editor. Firefox is a web browser (supposed to have HTML editor as well but I couldn't find one in the firefox I recently downloaded). Thunderbird is an email client. Details of all three at http://www.mozilla.org/products For Firefox and Thunderbird, the above website emphasizes enhanced security available in each. Security is not mentioned in the description of Mozilla. It also recommends that, rather than go for Mozilla, one should go for Firefox + Thunderbird. It is stated that Mozilla is not a combination of Firefox + Thunderbird. This leaves me somewhat pondering what the pros and cons may be. There's some advantage, in princple, in having it all rolled into one (as in Mozilla). On the other hand, if there's a distinct security advantage in FF + TB, then that's very tempting. But I have some concern that I couldn't find a Web Page editor in Firefox: as a browser, it seems to have less in it than Mozilla does. It also seems that the download size of Mozilla (12MB) is much less than Firefox (8MB) + Thunderbird (10MB). So if space were an issue, then Moz might be prefereable to FF + TB. On the other hand, the extra space may represent extra and valuable functionality. Any comments? Thanks, and best wishes to all, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 094 0861 [NB: New number!] Date: 06-Nov-04 Time: 20:43:06 ------------------------------ XFMail ------------------------------

Wireless network problem
by bjsamuels＠beenthere-donethat.org.uk 06 Nov '04

06 Nov '04

I am having some problems with my very small wireless network. I have ADSL via a 4-port Netgear DG834 router to which is connected my floor-standing machine running Debian Sarge (up to date). Connected to the router is a Netgear WG602 wireless access point. I also have a Dell Latitude (fairly old at 400 MHz) and a Netgear WG511 PCMCIA wireless network card. I bought the WG511 because I'd seen on the web that it worked well with Linux using the Prism54 drivers. I discovered shortly after the purchase that there were two versions of the card - one made in Taiwan and one made in China. The Chinese one didn't have the Prism chipset and would not work with the current Linux drivers. I, of course, ended up with the Chinese version. I then discovered 'ndiswrappers'. This Linux software acts as a translation layer between the Windows XP drivers, on the CD that came with the card, and Linux. I installed that and have a working card. That's where the problems start. I can connect to the Internet and get data transfer speeds which are the same as I'd expect with the eth0 PCMCIA network card in the laptop connected to the router by cable - about 60kb download. If I try to mount a directory on the floor-standing machine everything slows down. It takes around 7 seconds to mount the directory compared with instantaneous over the cable network, the 'ls' command takes 2 secs and 'ls -l' takes 50 seconds. During that 50 seconds the data transfer light on the WG511 flickers slowly and intermittently - the time when there is no data transfer is much greater overall than the time when data is being transferred. There is no great CPU activity either. Connecting from the floor-standing machine to the laptop is just as slow. Trying the same with X running makes it even slower. Screen repaints are also very slow under X. I just tried copying a small file from one machine to the other and typing and screen painting was very slow but the actual copy was almost instantaneous. It appears that just mounting something on the remote machine slows the laptop down and, once disconnected, every thing goes back to normal. This all makes communication between the two computers via wireless virtually unusable. Any suggestions would be gratefully received. I'm out of ideas (I never had many in the first place).
