Re: [Wlug] Linux From Scratch??

by Karl Hiramoto

Yes, I did it as some research into an embedded linux system. I setup the kernel and used busybox for base system. I also messed around with making my own /sbin/init for the embedded system that was only to have one process running. just for kicks, try putting a "hello world" program in /sbin/init sometime. make sure you have a backup & boot disk/CD though. > Have any us tried to build a Linux From Scratch? > > <http://lfs.oregonstate.edu/lfs/news.html> > > How did it go?

RE: [Wlug] Linux From Scratch??

by Skip Gaede

Ken, I used the modules and instructions on the web site back in the 2.x - 3.x days. In the process of building all the modules, you learn a lot. I even built a Linux distro that ran on a PPC Macintosh. There's also a couple of additional projects: ALFS (automated LFS) and BLFS (Beyond LFS) that cover modules you might need after getting the base system working.

Missing symbols usually indicate that the program wasn't compiled against the correct versions of your system libraries, or was compiled with different features enabled, etc. Perhaps your KMail can't use that libgpgme.so? Is there any other .so on your system that may work in place of that one? If both components (KDE Network and libgpgme.so) are stock from the distribution version SuSE 9.0, I would file a bug report with SuSE about it. If either component isn't stock, or is from a different version of SuSE than the other, then they will probably tell you it is unsupported. If you want to try to fix this yourself, you can try recompiling either component. It is probably easiest to try libgpgme.so first. rpm -qif <path-to-libgpgme.so> Download the Source RPM: shown in the output of that command and type: rpmbuild --rebuild foo.src.rpm During compilation, any errors about missing symbols should show up, or there may be "configure" output that says something about enabling/disabling certain features due to missing support in other parts of your system. Note that you may need to install several other development packages in order to compile that package, such as kdenetwork-devel or whatever SuSE's equivalent is.

I added the lines recommended by you, but I still get the same error about symbol "initialize" in kdenetwork3.so. I did restart the gpg-agent daemon.

Signed e-mails and Kmail

by Andy Stewart

Hi all, I'm playing around with digital signatures in e-mail, and I have that working on Kmail (KDE) wnen I send the e-mail. However, when I receive a signed e-mail, Kmail isn't able to automatically check the validity of the signature (unless I sent it). Within Kmail, I click on Settings->Configure Kmail->Security and point to libgpgme.so in the Crypto Plugins tab. I select that plugin and activate it. I then click the "configure" button and try to start the certificate manager. >From the KGpgCertManager, I get an error indicating that the symbol "initialize" was not found in libkdenetwork.so.2. I'm running SuSE 9.0 Pro, Kmail 1.5.4, and KDE 3.1.4. I've scoured the net to no avail. Does anybody have this working in Kmail?

Next meeting - PGP Keysigning?

by Charles R. Anderson

Ok, I'm not sure if this will fill the meeting's entire timeslot, so feel free to come up with another discussion topic. If you want to participate in the PGP Keysigning Party, here's what you need to do. This is based on GPG Keysigning Party HOWTO (http://www.cryptnet.net/fdp/crypto/gpg-party.html) which I highly recommend you read if this is the first time you are using GPG. You'll need to do these ahead of time *before* you arrive at the meeting, preferrably on a secure, local terminal (i.e. not in a computer lab or the public library or remotely from another system, or on a system running an insecure OS). 1. Generate A Key Pair gpg --gen-key (Default values are good. I would use 2048-bit key.) 1.5 Generate a revocation certificate gpg --output revoke.asc --gen-revoke <keyid> (save this revocation certificate offline in multiple places, print it out, put it in your safe, etc.) 2. Send Public Key To Designated (pgp.mit.edu) Keyserver gpg --send-key --keyserver=pgp.mit.edu <keyid> 3. Send Public Key Info To Coordinator Please email me (cra(a)wpi.edu) the output of: gpg --fingerprint <keyid> 4. Print a paper copy of your Public Key info from Step #3 I'll collate the keys and prepare copies of the public keys for all participants to use as a check list. Example output from Step #3: pub 1024D/49BB5886 2001-04-11 Charles R. Anderson <cra(a)wpi.edu> Key fingerprint = EBA3 A106 7C93 FA07 8E15 3AC2 C367 A0F9 49BB 5886 sub 2048g/B0817A13 2001-04-11 In this case, my <keyid> is 49BB5886, which is the same as the last 8 hex digits of the fingerprint. You can use your email address as <keyid> in the command if you forget your actual key id. So my full key information is: Key ID: 49BB5886 Key Type: DSA Hex Fingerprint: EBA3 A106 7C93 FA07 8E15 3AC2 C367 A0F9 49BB 5886 Key Size: 1024 bits (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.) 3.2 What participants should bring to the party 1. Themselves - you cannot participate virtually 2. Two forms of positive picture ID - a driver's license and passport are good 3. Key ID, Key Type, Hex Fingerprint and Key Size info (NOTE: please print out your own copy of your key to compare against my copy when you arrive.) 4. A Pen/Pencil 3.3 What Participants Should Not Bring to the Party 1. A Computer

How Barbaric!

by sageman＠WPI.EDU

--- "Hello, I'm running gentoo with 2.6.4 kernel" 2.6.4! 2.6.5 came out, like almost a whole 9 days ago! Let's see these priorities right already and upgrade this archaic, elder kernel already! Yeah, that's definitely sleep-inside-spinlock checks though. Just run your favorite kernel configurator (make config, or make xconfig or something), and under "Kernel Hacking" uncheck the "sleep-inside-spinlock checking" box. Hope it helps ^_^ http://sageman.res.wpi.net
