Hi Mike, Thanks for the reply, but please be a bit more specific. In the link you provided me, at what section of the page I am supposed to look for the solutions to the problems I encountered ? Please tell me, I really want to learn. And, as you can see from my post, I own two different set of systems (a Desktop PC and a Lenovo laptop) which can be used for testing purposes, so can I be of any assisstance to the Fedora Developer team ? As a novice, this is the best way I can participate in the development of FC and learn in the process too. As far as my educational background is concerned, I completed B-Tech in Computer Science & Engineering (CSE)in 2006, an equivalent to US based four year BS Computer Engineering program. I am good at programming in C and core Java. I am currently applying for MS Computer Science program in US Universities for the Fall 2008 session. I really want to learn and apply my creative skills effectively. So, if I can in any way participate in the development of Fedora Core, please let me know. Thanks and regards, Cyberbob Alt.

Let me know if there's anything I can do to help. I think that the big thing now is testing... FUDCon is starting in a few days so I don't want to make many major changes to the config but we need to make sure that it's going to be suitable for usage during FUDCon. Jeff

FC6 guests
by Luke Macken 09 Jan '08

09 Jan '08

So, we still have a handful of FC6 guests lying around in PHX. After a quick look, it seems that we're using them for the following services. publictest1 - pkgdb-dev - ns-slapd - mysqld - postgres - wevisor publictest2 - my mash/bodhi playground publictest4 - asterisk test1 - security irc bot / xmlrpc. Please feel free to chime in with any services / guests I'm missing. With regard to publictest2, this guest can go away and not come back. I'd be fine doing mash/bodhi testing on any guest that has a couple gigs of RAM and read-only access to /mnt/koji. So, in order to get this ball rolling, we need to determine which guests we want to upgrade / destroy, what OS we want to upgrade them to, and if the services are currently able to run on that OS. Also, when would the best time to upgrade be? luke

Announcing a new FIG! sysadmin-tools
by Mike McGrath 08 Jan '08

08 Jan '08

Similar to the web group the sysadmin-tools group has access to a number of our collaborative tools (in the future to include asterisk, gobby and likely mailman). If you're interested, stop by and join! I'm also looking for sponsors from those of you already in one of our groups. http://fedoraproject.org/wiki/Infrastructure/FIGs?action=show#head-8be7a537… -Mike

Fudcon and a busy week
by Mike McGrath 08 Jan '08

08 Jan '08

Hello everyone, just sending a reminder about FUDCon. Lots of us will be there, as such it will be harder to get ahold of us (unless you're also there) Additionally I'll be in Raleigh from the 9th to the 16th in many meetings so even after FUDCon I won't be as available as normal. -Mike

the syncmail script
by Mike McGrath 08 Jan '08

08 Jan '08

I know there's a lot of history around the syncmail script, does anyone know why we don't just stick a & at the end and fork it? I'm refering to the ctl+c to skip notifications issue. -Mike

I am having a peculiar problem
by Cyber Bob 07 Jan '08

07 Jan '08

Hi, I am an user of Fedora Core since 2003, and I've used versions 1.0 and 6.0. Though I've used both versions for quite some time now, I would still like to consider myself to be a novice, since Linux is still like a mysterious lady to me :). I am facing three peculiar problems with FC6 in two systems: 1. I own an Intel D865GBF based PC running an Intel 2.8 GHz processor with 512 MB MB (dual channel) DDR RAM. It houses two Seagate Baracuda 80 GB HDDs. FC6 was installed in a dual boot environment with WinXP, FC6 was installed in three primary partitions in the second HDD. Now the problem was that, whenever I tried to boot into FC6, system hanged at the "loading udev" line. I traced the source of this problem to be kernel-xen; since the problem vanished as soon as I unchecked the "Virtualisation" segment in all of the fresh installations post problem. I observed that it installed only "kernel" and not "kernel-xen". Can anyone please tell me whether my observations are correct or not, and whether there exists any solution to the problem with "kernel-xen" ? 2. I own a Lenovo 3000 Y500 notebook with 512 MB DDR RAM and 120 GB HDD. FC6 is installed in a dual boot environment with Win Vista that came preloaded. As soon as I update kernel, from the next boot onwards, the updated kernel is unable to detect the laptop keyboard whereas the default kernel works fine. The problem persisted even after updating hal, cups, seliux-policy targeted and xorg-x11. Am I doing something wrong ? The same setup seems to work fine in my PC. 3. Even after installing the latest JDK and JRE, the latest version of OpenOffice.org components fails to start even after giving a "installation success". I didn't installed the following bundled products: OpenOffice, Java, Java runtime, eclipse, firefox and thunderbird. I installed the latest releases of the above mentioned softwares from their respective sites. Any solutions ? Please give me a reply as soon as possible. I am eager to become a part of the FC6 Developers team, but before doing so I need to upgrade myself from novice status. For now, I would like to observe things and explore the way things work here. Wish me luck. Wishing you all a very happy prosperous new year, regards, Cyberbob (A)

Outages
by Mike McGrath 07 Jan '08

07 Jan '08

we've had some strange hardware outages over the last week or so. Basically 3 box reboots, one time xen6, and once or twice xen1 (I'll have to comb the logs more carefully) They appear to just lose power but by looking at the logs it seems they all lose connection to iscsi just before hand so something else might be going on. Just the same keep an eye out for anything strange. Those with access feel free to comb the logs for more information. I've contacted RHIS to see if they've seen any issues in the colo (brown out, issues with the netapp, etc) -Mike

Builder update
by Dennis Gilmore 07 Jan '08

07 Jan '08

We got ppc1 back on friday. Thanks to Mike for dealing with IBM to get it fixed and working again. I refreshed the OS on it so its now running RHEL5 the same as the other builders. its back in action and seems to be working fine. a few builds have gone through it ok. In the process of rebuilding ppc1 i renamed it from ppc1.fedora.redhat.com to ppc1.fedora.phx.redhat.com this is because it really does not cope well running both plague and koji. it only has 2 gb ram, ppc2 and ppc3 have the same cpu's but 4gb ram they are the two ppc boxes that can be used for plague. so to give a breakdown of the builders we have hammer2 plague koji xenbuilder1 plague koji xenbuilder2 plague koji xenbuilder4 koji ppc1 koji ppc2 plague koji ppc3 plague koji ppc4 koji now that FC-6 is EOL plague is only used for EPEL. to allow building of epel in koji requires some fairly invasive work. If any one wants to help please raise your hand. -- Dennis Gilmore

Intrusion Detection (aide review)
by Jason 06 Jan '08

06 Jan '08

Hey gang, I was talking to Mike McGrath the other day on IRC and inquired about the projects use of an IDS. Mike mentioned that project currently employs only hosts.deny type stuff. I recently setup aide for use on a personal server but it looked flexible enough for use in a more robust type environment. The idea behind this write up is to see what others think about employing something like this to give an idea of what aide in particular is capable of. The Name: AIDE (Advanced Intrusion Detection Environment) What it Does: Constructs a database of files as specified in the configuration file (aide.conf). The database stores file attributes including permissions, inode number, user, group, file size, mtime, ctime, atime, growing size, number of links and link name. Based on options specified at compile time, acl, xattr and selinux attributes can be stored as well. When initialized and when checks are run, aide creates a crypto checksum/hash of each file watched using any number of algorithms (e.g. sha1, sha256, etc.). The Config File: This is where the directories/files to be watched (and what in particular is watched on the files) and the directories/files to be excluded, reporting options (default goes to /var/log/aide/aide.log) Misc. Notes: * Postgres can be used to store databases * For usage in multiple machine environments, the database can be stored in a central location and aide ran with --compare to limit resource hogging. * The database and config file can be signed, this makes it so that if a change is manually made to either file, aide will refuse to use it, as the signature will have been voided. * Aide can be run with --update which will create a new database, however it doesn't take effect until manually copied to the check database. This allows updates to be frequently tracked but not put into the check database. The main weakness I noted was in the reporting capabilities. According to the config file notes, reporting can be done via stdout, stdin, stderr, file://, fd: (file descriptor). I only have the one machine and it runs a pretty vanilla config as I don't do anything too fancy with it. With the config I have it seems to work as advertised. So there it is, thoughts? Regards, Jason
