I offered to either give a talk on home virtualization or ownCloud (or both) depending on people's interest (ownCloud is basically a privately hostable Dropbox solution).

The box should already be semi setup to use an address between 192.168.1.101-105, or something like that. I don't remember exactly what I used and I'm not at home to check. The LANCE part is the ethernet chip, eth0 is the interface you need to use to access the net. Do you have any errors in the log file when you run dhcpd on the box? It might need to have some stuff put into /etc/dhcpd.conf to get it working right. I can check this at home if need be. And if need be, I can rip a copy of RH 6.1 for Sparc and bring it to the next meeting for those who'd like to get packages for it. John

PGP Key Signing Party

by Eric Martin

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 This upcoming meeting we are going to have a PGP Key Signing Party. For those of you who don't know what PGP is, allow me to briefly explain. This is all base off of the GPG Key Signing HOWTO (http://www.rubin.ch/pgp/kspa/gpg-party.en.html) which I suggest for further reading. Those who do know can feel free to skip down to the next paragraph. PGP stands for Pretty Good Privacy, and is a Public Key Infrastructure that allows us to communicate securely and deal with data in a secure fashion. There is a public key that one would typically upload to a server and a private key that you hold on to. With the private key you can decrypt / sign, and with the public key you can encrypt / verify emails and documents. Key signatures come into play when you validate that a specific key belongs to a specific person and extend the web of trust. Here's what needs to be done BEFORE the meeting on your computer, or on a secure terminal (e.g. not in a computer lab on your campus). I'll post directions both for GPG (Gnu Privacy Guard) and Kgpg (the KDE front - -end to gpg for all of those who like GUIs). 1. Generate a Key Pair / Verify your key won't expire soon gpg --gen-key (Default values of DSA/Elgamal is fine and the default of 2048 is good.) I recommend 3 - 5 years for a key lifespan (how long the key will be good for) 1a) for those of you wishing to use Kgpg, goto Keys -> Generate Key Pair and fill in the dialog box Once you create the New key pair, check the Save As box under _Revocation Certificate_ to save a Revocation Certificate (see 2) 1c) For those of you who already have a key, make sure yours isn't about to expire (like mine did). If it has expired, you can extend the life by $ gpg --edit-key <key-id> and typing expire at the command prompt next, generate a new key-pair and sign your new key with your old key so anyone who trusted your old one will trust the new one. 2) Generate a revocation certificate Revocation certificates are for situations where you forget your passphrase, the key becomes comprised, etc you can revoke your key. $ gpg --output revoke.asc --gen-revoke <key-id> Save this in multiple places, print a copy etc in case you need it. 2GUI) If you didn't create a revocation cert in Kgpg, just right click on your new key and select Revoke Key. when the box pops up only check Save As 3) Upload your key to the Designated server for this party (pgp.mit.edu) $ gpg --send-key --keyserver=pgp.mit.edu <key-id> 3GUI) Right Click on the Key, select Export Public Keys, select Default Key Server (make sure it's pgp.mit.edu under Settings) 4) Email me your key's fingerprint so I can add it to the list $ gpg --fingerprint <key-id> Copy and Paste that into an email to the coordinator (me, Eric Martin). 5) print out a copy of that same output and bring it to the meeting. I'll make up a check list and bring them to the meeting for everyone to use. Example output from Step 4: pub 1024D/A9413B9F 2007-04-09 [expires: 2010-04-08] Key fingerprint = D1C4 086E DBB5 C18E 6FDA B215 6A25 7174 A941 3B9F uid Eric J.

Martin <freak4uxxx(a)gmail.com> sub 2048g/01F81B8E 2007-04-09 [expires: 2010-04-08] my <key-id> is A9413B9F (which is always the same as my last 8 hex digits of my fingerprint). If like me you don't always remember your key-id you can use your email address and it will still work. My full key information is: Key ID: A9413B9F Key Type: DSA Hex Fingerprint: D1C4 086E DBB5 C18E 6FDA B215 6A25 7174 A941 3B9F Key Size: 1024 (The DSA key is always 1024 bits. The ElGamal Encryption key is 2048 bits in my case, but isn't needed for the keysigning party.) What you should bring to this party 1. Yourself, no exceptions 2. Two forms of positive photo ID - driver's license and passport are good 3. Key Id, Key Type, Hex Fingerprint and Key size info ***Please print out your own copy of your info to compare against mine when you arrive *** 4. Pen / Pencil What you Should Not Bring 1. Computer I want to thank Chuck Anderson for helping me out. If you have any questions please let me know.

From the viewpoint of a jit.si watcher, that was one of the most fun demos of a program I have seen at a WLUG over the decades. But eye-candy aside, I was most interested that the demonstrator claimed to understand how it works and to have some links. The meaning of words changes over time. More change in less time now. A cartoon generating program is called "artificial intelligence". I can't draw cartoons, so I must not be intelligent. The words "machine learning" were used. As I said Thursday, I did my dissertation on machine learning. At that time, it meant a computer (with appropriate programming) would input a sequence of examples, each marked as in or not in a certain class. The computer would then (we hoped) be able to correctly classify examples that had not been explicitly shown before. I didn't see anything like that in the demo. It was said to be based on a "neural net", but neural nets have been around since Minsky started inventing words back in the fifties. What changed to make neural networks suddenly start working? -- Keith

Hi gang, Thanks for the additional info. I'll take a look at this info shortly. I've also found some information in "Grokking the GIMP" with regard to how to use some features of the GIMP to enhance scanned images. This was most helpful when I discovered that scanning images from a magazine or calendar (printed material) caused a speckling effect to appear in the resulting image. The GIMP has a despeckling filter that removes this rather well in many cases. This entire topic has me wondering if a detailed examination of the features of the GIMP might be a good discussion for a future meeting. There seems to be much more there than originally meets the eye. Later, Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org

John, I can't make it to tonight's WLUG meeting. However, I'd like to buy two of these (@ $40 each) if we can make other arrangements for pickup.

Hello, My name is Forrest I am a gamer and a Linux enthusiast that mainly uses a Arch Based distro called Manjaro. My friend reached out to the group for me and then emailed and told me about it so I thought I would create a account and introduce myself. I would also like to say my level of understanding is probably more on the beginners level of things and have been learning slowly and would like to learn more about other things like raspberry pis and servers since I recently obtained a server from a family members work because they upgraded, I will also leave specs of the two custom built computers I own and the name of the server I have down below, I look forward to meeting you all next meeting.

Re: Reminder: Virtual Meeting today at 7PM Topic: Emacs awesomeness.

by gmcaplan＠gmcaplan.org

I was hoping to attend, but it looks like I will not be able to. I hope it will be recorded because I, too, would like to learn about emacs. Also, I have two questions: 1. I am running Ubuntu 18.04 LTS. When I update to ver. 20 or 22, I would prefer to do a "clean" re-install, but I have a question. Does that mean I must get a list of all my installed software and re-install them one at a time after I upgrade the OS? If so, is there an easy way for me to get the list? 2. I have been learning to use the software language R. I have a couple of questions and I would like to hear from anyone who has R experience. Thank You.
