Remote access with DansGuardian / FireHOL / TinyProxy
by Andrew C Wilkin 28 Aug '09

28 Aug '09

Is there anyone local who knows about DansGuardian? I'm having trouble logging into my work and I'm 95% positive it's because of DG. It's probably some configuration thing I don't know about. Any help?

looking for PHP 5.2.x help
by John Stoffel 28 Aug '09

28 Aug '09

Guys, I'm looking for some help with PHP5.2.x hacking on a web site to cleanup how the user submitted search form is handled. Basically I want to make it simple for the end user to a) refine their query, b) not have to answer popups if they hit the reload button, and c) so I can leanr more PHP. I found this nice reference: http://us2.php.net/manual/en/language.variables.external.php which has two sections by "wayne" and "Jonas Lindel" talking about how you can take the results of a PHP POST request, stuff the vars into your session, and redirect back to the same page without the POST vars set, then complete the query. The idea is so that when people hit the "back" or "reload" buttons, they don't keep getting asked whether they want to resubmit their data. It's not strictly needed, but it would be a nice cleanup of the interface. Here's the snippet I'm trying to use, which bombs out with: Fatal error: Cannot re-assign $this in .... on line 45 And the code I'm using is: <? // We want to put the search query into a session so we can restore it // easily when users goto look at full_holdings.php and then return to // the overall display page. We'll need to do a session_destroy in // index.php I think. See the tutorial(s) at // http://www.phpf1.com/tutorial/php-sessions.html // http://us3.php.net/manual/en/book.session.php session_start(); // Now see Jonas Lindel's & Wayne's code at // http://us2.php.net/manual/en/language.variables.external.php for // this *nice* trick. //is there POST or GET data we should look at if($_POST or ($_GET and (!isset($_SESSION['skipnextget'])))) { //is there GET data? if($_GET) { $newgetarr = array(); foreach($_GET as $key => $value) { if(is_array($value)) { //if it's an array, convert it to comma separated $newvalue = implode(',',$value); } else { $newvalue = $value; } $newgetarr[] = $key.'='.$newvalue; } $newget = implode('&',$newgetarr); $_SESSION['skipnextget'] = 1; } foreach($_POST as $key => $value) { $this[$key] = $value; } $_SESSION['postvars'] = serialize($this); //put POST in the session header("Location: http://" .$_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'] . '?\ ' . $newget); //reload page without POST data and shorter GET data exit(); } else { //after reloading we'll come right to this spot session_unregister('skipnextget'); if(isset($_SESSION['postvars'])) { //load the POST variables from the session // Error on this line below! $this = unserialize($_SESSION['postvars']); session_unregister('postvars'); //delete the session stuff we //don't need anymore. return $this; } }

getting rid of some monitors
by Jared Greenwald 20 Aug '09

20 Aug '09

I apologize in advance for spamming the list with my want ad. I need to get rid of some CRT monitors and am wondering if anyone on the list would be interested. They are as follows... 1x Gateway Vivitron (circa '95) 17" 1x Compaq MV940 19" 2x Digital re-branded Trinitron 21" (matched pair) The 19" and 21" monitors can each run at 1600x1200 and the 21s have dual input, which is nice. I used the 21s in a TwinView setup on my main Ubuntu-based workstation at home for years until I got a LCD last Christmas. I have power/video cables for all of them, so they are ready to roll. I had them up on craigslist to try and sell them, but haven't gotten any hits and it's just time to clear out the space. The catch is that you would need to come pick them up from me in Uxbridge. Please respond to me privately so we don't spam the list. Thanks, Jared Greenwald

Re: [Wlug] Wlug Digest, Vol 70, Issue 17

The issue with 60 Hz and the LCD was not flicker. I mentioned visual defects. I meant things like missing pixels. I had to use the analog connection because that was all that was available on the PC that I had just bought. I just looked at the setting now to see if I had really chosen 120 Hz which is still a harmonic of 60Hz. Unfortunately for looking at the setting, I moved three years ago from the house where the office had fluorescent lights. When I set up my computer again in the new house, I must have somehow gone back to the default 60 Hz. There are no fluorescent lights around and there are none of the visual defects I saw in the other house. When I brought my unit back to Fry's electronics they had no such problem in the store from the ceiling lights which were a good 15 or more feet away. They gave me a replacement anyway just to keep me happy. I had not even suspected fluorescent lights at that point. When I got the replacement home, it had the same problem as the first one. I was about to give up on Samsung in disgust when I asked around at work if anybody could figure out the problem. Our computer hardware support person mentioned the fluorescent light idea. I went home, changed the frequency and the problems disappeared. The fluorescent lights in my home office were probably only 4 feet from the LCD. The cause of the problem might have been something completely different, but I cannot come up with another explanation that fits the observations. Maybe I had sympathetic 60 Hz fluctuations from my neighbor's ham radio. Whatever was the cause, getting away from 60Hz seemed to be the solution. /Steve -- Steven Greenberg Email: steve(a)ssgreenberg.name 251 Holland Rd.

Here I am begging again.
by Ken Jones 20 Aug '09

20 Aug '09

I have not been making the meetings. That does not mean my SUN ULTRA1 running Aurora Linux can no longer create 'interesting' problems. This time the second SUN ULTRA running Gentoo is in cahoots. I have a new SAMSUNG SyncMaster flat screen monitor. I have attached this monitor via a Belkin SUN adapter to my ULTRA1's. It does not work!! The monitor flashes a little square window saying something about "Not optimum mode". It feels that it has not been configured correctly. The buttons on the right of the monitor, which are there to set it up, also do not work with the SUN's is attached. The monitor works fine with PC type machinery. The Belkin worked fine with a regular old tube monitor. (I have not dug out the old monitor to check whether it still works. I suspect it does.) Anybody have any ideas?

I have a Samsung SyncMaster 204B, but it is on a Windows PC. As for the frequency, 60 Hz is not good in close proximity to fluorescent lights. I had a lot of visual defects in two different units, until I changed to 120 Hz(I think). /Steve -- Steven Greenberg Email: steve(a)ssgreenberg.name 251 Holland Rd.
