General :: Monitoring For A Change In A Web Page?
Apr 3, 2011
I'm trying to write some bash script to monitor for a change in web pages.'m using WGET (through a cronjob) to collect the pages, then use DIFF to compare the previous and current page for changes, then just sending a notification to indicate if a change is detected.This was all working great in the simple test environment until I tried monitoring a page that had a dynamic link . Where nearly every test brought up a difference.So to my question, is there a way to do a DIFF on a couple of web pages but configure it to exclude dynamic links?

I have xfce on my machine, running lucid lynx. For some weird reason, I can't change my firefox home page. I've changed it to the same one time and again in preferences, but every time I open firefox, it shows all the files in my home directory, including hidden ones. I uncheck the "show hidden files box", change it again in "preferences", but it still does this. And the home page in "preferences" is set to the right page I want; firefox just won't go there when I start it up. I really don't want my home directory in plain view like that; how do I make firefox recognize my settings?

I am running OpenSuSE 11.0 KDE 3.5.9 "release 49.1" with Kivio 1.6.3. I am using Kivio to create large flow charts (paper size is 44in x36in) and I have an HP DesignJet 800PS that is capable of printing documents this size. We handle blue prints occasionally as well as when I have large documents (size wise) to print.
Anyhow I have a table relationship drawing I have created and I need to print it out. Now I have come up with a work around (save the document as PNG, import it into OpenOffice then save as PDF and print...) but when I try to print as PDF, I get the default paper size of A4 and the option to change the paper size is ghosted in Kivio. Also I only get a small segment of the actual drawing.

I have a box that's used as an SFTP server. All users have restricted shell so they can only use SFTP to send and receive files. But it makes it hard to have them change their passwords. I thought that if we had a web page set up where the user could enter their username, old password, new password and confirmed new password, that this would be the easiest solution.

I have a document with page numbers in the Table of Contents in Roman Numurals. I would like to change them to numbers 1, 2, 3. How would I do this? I'm not finding any help on the Internet and in Openoffice help. If I change the numbers manually, they will revert back when I update the Table of Contents.

I have been trying to set up SNMP monitoring using Cricket. I believe I have Cricket running fine, however I also believe that I have SNMP set up wrong. When I do an SNMPWALK I get the following:
[Code]....
This tells me I have SNMP running, however I would expect to see a lot more data... Am I correct, should I see more data? I spoke to a friend, and he suggested that I have something not set up correctly in SNMP dealing with the community string...

I wonder if there is any tool that can read health of my HDD's? There are tons in windows but what options are there in Linux? I would really hope there is a tool a can install without using terminal cause I dont have web access for the Xubuntu right now. If anyone aware of such a tool, preferable a .deb file so I can easily install without hazzle. Also I hope tools like that are not littered with tons of dependencies. Cause those dependencies are a major challenge without online connection. If there exist any smart terminal commands that will let med check health status pls let me know and pls write down the command. I have enabled the s.m.a.r.t in BIOS.
I have 4 drives running Raid 0 if that matters.

On FC11 64 bit with Adobe flash plugin for Linux installed, I see segfault errors from "npviewer" in /var/log/messages. The only browser I have tried yet, Firefox, has glitches every now and then. Sometimes it shows the title of a page in a tab, but the page is blank. This can even happen when I try the Google main page. Is it true that npviewer has something to do with Adobe flash? Is there a way to fix the problem? If it is caused by Adobe flash, is there a different plugin that will replace Adobe flash player?

I have a problem printing to my HP printer.
What is my problem? I have a page (one page - text an graphic) to print. When I sent it to my printer it prints OK. When I sent it agian, the output is totally garbled. When I sent it again (a third time) it is OK. Sent it again (4th time) it is garbled. Sent it again ... you get the picture ;-). Alternating good and bad pages.
What is my setup? I run Fedora 14 with Cups 1.4.6. The printer is a HP Deskjet 940C. It is connected to a linksys wireless print server. It is configured in CUPS to use ipp printing. The driver I use in Cups is 'CUPS+Gutenprint v5.2.6 Simplified (color, 2-sided printing)'.

I have apache httpd server on my Fedora 10I got 2 problems:First : I copied the web page files to its Document Root <var/www/html> & Disabled the default web page. But when I visit http:/localhost ，it shows up the list of files in <var/www/html> as if a ftp server browsed in web page. So how can I set http://localhost load my default web page index.html ?Second :I want to set up a web server on Internet through my router . I applied for DDNS account & input it into router correctly . I set virtual host in server to redirect any access from port 80 to 192.168.1.2:80 in LAN . Just for in case , I also download and running the DDNS software & installed it on PC 192.168.1.2 in LAN . My DDNS provider is oray.cn . It's a Chinese server provider . I don't think there is anything wrong with oray.cn . But if you need its information just visit oray.cn (Google can translate it for you). So I want to know did I miss something to set up a web server in this kind of situation

Is there a 'top' like command for monitoring the GPU and memory usage of a video card? I am most interested in Linux commands, but and OS would be interesting. I strongly suspect that for a group of my systems the video cards are being under-utilized (but I have no idea by how much) and would like to re-allocate funds to other bottle-necks. We are using higher end cards, so the price difference between cards is significant.
