Hi, Anyone on here using Charter Telephone VOIP service? I've currently got Verizon, but the wife hates it because our phone lines get flaky all the time, esp when it rains. So I'm thinking to save money and combine all my stuff onto Charter. I've already got High Speed internet and regular old cable. Not wild about Digital Cable since I'm happy with Tivo and I don't want yet another set top box to have to deal with... So, any horror stories about Charter Phone VOIP quality and service? Thanks, John

Overriding NIS accounts

by Bill Mills-Curran

I have an issue at my work with the configuration of one of our several flavors of linux servers. The goal is to override the NIS-specified login directory definition by using this syntax in /etc/passwd: +userx:::::/home/userx: +@grpx:::::: +:::::: /etc/nsswitch.conf has (in part): passwd: compat shadow: files nis group: files nis The distribution is Red Hat Enterprise Linux Server release 5.2 (Tikanga). If this was working I would get the following: > echo ~userx /home/userx Instead, I'm getting the login dir specified in NIS. I've successfully configured a Red Hat 6.3 server to work properly, but this one is driving me batty. Any suggestions? TIA, Bill

Possible intrusion?

by Bill Mills-Curran

I was looking at the output of "last" recently and found several entries like this on my home server: userxx pts/0 c-24-91-141-172. Sun Dec 2 14:57 - 15:09 (00:11) (userxx represents my username) I did a reverse lookup on 172.141.92.24: host 172.141.92.24 24.92.141.172.in-addr.arpa domain name pointer AC8D5C18.ipt.aol.com. Looks like something from AOL. I got a little freaked, so I changed my password and also blocked that IP in /etc/hosts.deny. I'm not an aol user, but my wife is... but the "last" output shows this as connecting with my username. Any ideas? Thanks, Bill

Re: [Wlug] Using Facebook as a Website

by Steven Greenberg

I don't think it is a question of Facebook or a website. Maybe the title of my email gave that impression. We can use both. Use Facebook for what it is good for (if that is anything), and use the web site for what it is good for. Creating events and managing RSVP might be something to leave to Facebook. Although, if we used one of the CMS software systems, it could probably do that job. For instance, I use my personal Facebook site only to have links to my blog articles on my web site. I agree, that I want to own the data on my blog. All my photo albums are on my own website. On the Facebook create group page there is an option to set privacy to: Privacy: Open Anyone can see the group, who's in it, and what members post. Actually, I suppose that may already be the setting. The description does not imply that you do not need to at least login to Facebook to see the group. /Steve -- Steven Greenberg Email: steve(a)ssgreenberg.name 251 Holland Rd.

Using Facebook as a Website

by Steven Greenberg

In the meeting, I also mentioned using Facebook. This is just about the easiest thing to set up. Here is an example Facebook Page that I have created. You do not need to sign in to Facebook to read it. https://www.facebook.com/SturbridgeForElizabethWarren /Steve -- Steven Greenberg Email: steve(a)ssgreenberg.name 251 Holland Rd.

Re: [Wlug] Using Facebook as a Website

by Steven Greenberg

https://www.facebook.com/SturbridgeForElizabethWarren does not require a login to Facebook. Facebook presents you with a login page, but you can just dismiss the login page to read the original. This is not true of https://www.facebook.com/groups/worcester.linux.users.group/ If the owner of https://www.facebook.com/groups/worcester.linux.users.group/ could open up access to this page so that you do not need to log in to read it, then this would be a great step forward. This facebook page ought to be mentioned on the web site. http://www.wlug.org/. That way, knowledge of the facebook page would not fade into memory in the archive of these emails. /Steve -- Steven Greenberg Email: steve(a)ssgreenberg.name 251 Holland Rd.

Setting up a Wiki

by Steven Greenberg

Some mention was made of setting up a Wiki web site. I have set up and contributed to Wikis in several companies where I worked. Those are internal web sites, so I cannot show examples. The software I used was Twiki. http://twiki.org/ /Steve -- Steven Greenberg Email: steve(a)ssgreenberg.name 251 Holland Rd.

Re: [Wlug] Need some help with digital signal processing ...

Jeff, I will look at reddit forums. However, I am hoping for someone local for beer and pizza based information interchange.

I will do the programming. We've got some smart folks on this list, no doubt, but it might serve you better to ask this question in a more focused forum.

Examples of Websites Using Different Techniques

by Steven Greenberg

I have examples of three different techniques that I have used for creating web sites. My personal web site is mostly hand coded HTML and CSS, with some custom Javascript and PHP. The drop down menus are pure HTML and CSS. http://www.ssgreenberg.name/ The politics link on my website takes you to my politics blog that uses Wordpress. http://ssgreenberg.name/PoliticsBlog/ I have my experimental website using Drupal 6. http://www.ssgreenberg.name/Drupal/Drupal/ the last example is the Friends of The Joshua Hyde Public Library on which I have used Drupal 7 http://www.sturbridgelibraryfriends.org/ I did a much more complex web site in Drupal 6 for a Square dance club, but that site is no longer available. I'll be happy to discuss the pros and cons of each technique. /Steve P.S. I have some Javascript which I use often for doing Outlines on web sites in HTML. http://www.ssgreenberg.name/SSGSoftware/OutlinesInHTML/ I also have some Javascript which I use to display all my photo albums on the web. One example is: http://www.ssgreenberg.name/Pictures/2011/10-28-Snow/index.php The software at the bottom of these pages that keep track of and displays the info about how many reads and readers there are for each page was also written by me and uses a MySQL database to keep the data that drives the display of information. -- Steven Greenberg Email: steve(a)ssgreenberg.name 251 Holland Rd.
