USB to serial converter, detected but not there - huh?
by Chris G 06 Aug '07

I am trying to get a USB to Serial converter working with my Slackware system. When I plug the converter into a USB port it works exactly as one would expect and hope, in /var/log/messages I see:- Aug 6 15:34:16 home kernel: usb 3-2: new full speed USB device using uhci_hcd and address 2 Aug 6 15:34:16 home kernel: usb 3-2: configuration #1 chosen from 1 choice Aug 6 15:34:16 home kernel: usbcore: registered new driver usbserial Aug 6 15:34:16 home kernel: drivers/usb/serial/usb-serial.c: USB Serial support registered for generic Aug 6 15:34:16 home kernel: usbcore: registered new driver usbserial_generic Aug 6 15:34:16 home kernel: drivers/usb/serial/usb-serial.c: USB Serial Driver core Aug 6 15:34:16 home kernel: drivers/usb/serial/usb-serial.c: USB Serial support registered for pl2303 Aug 6 15:34:16 home kernel: pl2303 3-2:1.0: pl2303 converter detected Aug 6 15:34:16 home kernel: usb 3-2: pl2303 converter now attached to ttyUSB0 Aug 6 15:34:16 home kernel: usbcore: registered new driver pl2303 Aug 6 15:34:16 home kernel: drivers/usb/serial/pl2303.c: Prolific PL2303 USB to serial adaptor driver if I unplug it and plug it back in I see:- Aug 6 15:53:18 home kernel: usb 3-2: USB disconnect, address 2 Aug 6 15:53:18 home kernel: pl2303 ttyUSB0: pl2303 converter now disconnected from ttyUSB0 Aug 6 15:53:18 home kernel: pl2303 3-2:1.0: device disconnected Aug 6 15:53:41 home kernel: usb 3-2: new full speed USB device using uhci_hcd and address 3 Aug 6 15:53:41 home kernel: usb 3-2: configuration #1 chosen from 1 choice Aug 6 15:53:41 home kernel: pl2303 3-2:1.0: pl2303 converter detected Aug 6 15:53:41 home kernel: usb 3-2: pl2303 converter now attached to ttyUSB0 The only (?!) problem is that I don't actually get a /dev/ttyUSB0, so what's wrong and/or how can I diagnose it? -- Chris Green

It's all a bit hit and miss. When I first started with Debian it tended to turn things on by default, and even now a lot of packages still seem to. While I can understand (and agree with) the logic of not dumping daemons onto a server and running them without configuring them, it's annoying how many packages seem to come without any configuration help. Even telling me which documentation to read first is better than nothing, but some don't even manage that. I should stop moaning and starting learning to maintain packages ;-) Matthew

Re: Problem getting Apache/Firefox to display PHP webpages

If it works, then probably it's as well to carry on the way it is now, but if memory serves the normal PHP handler shouldn't need any of that. CGI scripts need execute permission to invoke their interpreters, but the PHP interpreter is invoked by Apache so PHP scripts need only be readable. Although there are security advantages to segregating them like CGI scripts, PHP files were intended to live in the document space with the static content. That said, I really don't know what was causing your problem before. As for getting it to start automatically, are you sure it isn't already? Try `netstat -at` after a fresh boot to see if something is listening on 'www'. If not, look for directories called /etc/rc{n}.d, for various {n} being the runlevels your system will do. These contain symlinks to the scripts in /etc/init.d and determine which services are started/killed when entering/leaving different runlevels. Either the installer didn't put the links in, or it made them for the wrong runlevel. You can probably use `who -r` to check your current runlevel (or `runlevel` as root). Use update-rc.d to make the links in the proper formats: check its man-page for options you might want. Hope that helps, Matthew

Weirdo gnome thing
by ted.harding＠nessie.mcc.ac.uk 04 Aug '07

04 Aug '07

Hi Folks, I just had a weird experience with Gnome. Context: I have 10 "workspaces" with, at present, respectively 3, 1, 0, 0, 5, 2, 1, 2, 5, 1 windows on them for various tasks. One of the 5 windows on workspace 5 is my mailer program, and the window on workspace 10 is my browser (firefox). In workspace 5, in the mailer, I middle-clicked on one of the mail messages in the list. The normal effect of this is to pop up a new window with the message in it. This it duly did -- but I was switched into workspace 10 with the message window on top of the browser window. After I'd dealt with that, I then found that every single window in every workspace had been shifted down by the same amount (about 15 pixels) and right by the same amount (about 2 pixels). This is weird! Anyone ever seen the like? Thanks, and best wishes, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <ted.harding(a)nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 04-Aug-07 Time: 13:18:49 ------------------------------ XFMail ------------------------------

Video Turtorial at next Ipswich meet
by Wayne Stallwood 04 Aug '07

04 Aug '07

Monday the 20th of August at The Milestone Beer House 8PM http://www.alug.org.uk/wiki/moin.cgi/Meetings As promised I will be hosting a beginners guide/introduction to video editing and production on Linux at the next Ipswich Meeting. The general lesson plan is to go through all the steps necessary to produce a DVD (with front menus) from some raw DV footage taken from a standard digital video camera. Most of the steps will also be relevant to creating video content for online services such as youtube. During the production of this DVD (using very short clips so that the lesson does not mostly comprise of watching progress bars) we will cover clipping and editing of footage, modification and dubbing of soundtracks, applying post-production effects, building DVD menus and producing the DVD itself. In addition to the film clip we will also be producing a slideshow from some digital photos. With additions to the DVD menu to allow the end user to select this from the front screen. If we get time I will also demonstrate a quicker way of making a DVD with just the slideshow, which is a useful way of distributing pictures to friends and family who do not have a computer but may have a DVD player. This as I said will be a beginners introduction, anybody that has spent any time with these tools will probably be at least as well informed as the instructor :) Hope to see some of you there Wayne

Problem getting Apache/Firefox to display PHP webpages
by sagr 01 Aug '07

01 Aug '07

Following the advice of some ALUGers in a previous thread I am in the process of upgrading our fileserver to Ubuntu 7.04. I have successfully installed Ubutu on it and then apt-get installed the modules "apache" and "php5-mysql". I have created a simple three line "hello world" PHP prog and saved it in /var/www as hello.php : root@wildebeest:/var/www# cat hello.php <?php echo "Hello World"; ?> If I type the URL http://localhost/ into firefox I see the default apache index.html holding page as expected (so I know apache is running). If however I type the URL http://localhost/hello.php a box pops up in Firefox saying: "You have chosen to open: hello.php Which is a: PHP script From: http://localhost What should Firefox do with this file? 1. Open with gedit (default) 2. Save to disc." Why doesn't Firefox simply display hello.php as a webpage? What am I doing wrong? Do I need to configure something in apache and/or Firefox to display php files as webpages? Any help welcome! Sagr.

Evolution downloads duplicate emails each time it connects to POP server
by sagr 01 Aug '07

01 Aug '07

Hi Folks, I have recently installed Ubuntu 7.04 and am using the Evolution mail client version 2.10.1 to access my POP server hosted by 1&1. I access my emails via two PC's (one running Windows, the other Linux) so have set Evolution (on my Linux PC) to "Leave Message On Server" so they are available to download on my Windows PC (I currently use Windows as my main PC but just want occasional access to email on my Linux PC). The problem is that when I tell Evolution to "Send & Receive" it downloads all the emails on the POP server even though it has already downloaded them earlier. I am therefore downloading a complete duplicate set of emails each time I do a "Send & Receive" filling my Evolution inbox with multiple copies of the same emails. Is this a problem with Evolution, Linux, my ISP's POP server, or just because I have incorrectly configured something? Any suggestions welcome! Sagr.
