Linux alternative to MS Netmeeting
by Matt Shields 09 Jan '07

09 Jan '07

In the company I work for, quite a few people use Netmeeting to share desktops during training. Anyone know of a way to either connect to their Netmeeting, or an alternative that will work on both Windows & Linux, and not require a server to host the meeting. Matt

Using CentOS 4.4 on very old Dell Inspiron 3500 laptop; would like suggestions regarding using KDE/GNOME in low RAM and low disk situation
by Kenneth Wolcott 09 Jan '07

09 Jan '07

Hi; I'm new to the CentOS list and I only have experience with CentOS 4.3/4.4 on desktops. I just installed CentOS 4.4 on a very old Dell Inspiron 3500 laptop. I choose the desktop option and then deleted the kde and gnome packages because I have only 192mb RAM and 4gb disk (total). I'd like suggestions on how to maximize the effective usage of the laptop with CentOS 4.4...as a minimum I want to do secure wireless web browsing. If KDE or GNOME needs more disk/RAM than I have available is XCFE the only alternative to the bleak Motif experience? I don't have any money to get a better laptop or to upgrade the RAM and/or disk at this time. Thanks, Ken Wolcott

FOSDEM Request For Proposal
by Dag Wieers 09 Jan '07

09 Jan '07

Hi, For those attending FOSDEM either as volunteer or as a participant, we are looking for interesting presentations about CentOS. If you're interested for one or more topics, please contact me. The deadline for the proposal is Tuesday 23 january 2007. In our developers room (that we share with Fedora) we have about 6 slots of 50mins available that we can divide in 12 slots of 20mins if necessary. More information is available in the wiki at: http://wiki.centos.org/Events/Fosdem2007 We organise a pre-FOSDEM meeting on friday with CentOS and Fedora people in Brussels, more info about that at: http://wiki.centos.org/Events/PreFosdem2007 Below is more information about the deadline for the FOSDEM organisation as well as the insurance rules for those that bring hardware for the booth or for the devroom. Kind regards, -- dag wieers, dag(a)wieers.com, http://dag.wieers.com/ -- [all I want is a warm bed and a kind word and unlimited power] ---------- Forwarded message ---------- From: Pascal Bleser <loki(a)fosdem.org> To: fhornain(a)axen.info, dag(a)wieers.com, chitlesh(a)fedoraproject.org Organization: FOSDEM Date: Mon, 01 Jan 2007 03:33:34 +0100 User-Agent: Thunderbird 1.5.0.9 (X11/20060911) Subject: [FOSDEM Devrooms] Hardware insurance + Schedule deadline X-Spam-Status: No, score=-1.4 required=3.0 tests=AWL,BAYES_00, FORGED_RCVD_HELO autolearn=unavailable version=3.1.7 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 First of all, wishing you a happy new year to you, your family and friends ;) Hardware Insurance ================== As we did at past editions of FOSDEM, we again provide an insurance for the hardware you'll bring along. That insurance - - is free of charge for you - - is intended for speakers in your devroom (we can't pay the insurance for the 4000+ visitors ;)) What we need from you is, for each device: - - the name and email address of the owner - - the type of device (notebook, network switch, PDA, ...) - - the vendor and name of the device (e.g. Dell Latitude D800) - - some sort of unique identifier that is visible on the device (typically the serial number) - - an estimation of its current value, in EUR Note that our insurance will only cover the hardware for which we've received the information as above *before Mon 19 Feb*. Schedule deadline ================= The deadline for sending us your devroom schedule is *Sat 3rd February* That gives us a week to hack all the data into our CMS and possibly make some adjustments afterwards. Please understand that we have to encode all the data and that we'd like to have all the information available on the website for visitors 2-3 weeks before the event. Note that if you already have part of the schedule, you can already send us that information (so we can start adding the content now ;)), even if you don't know yet at what time the talk will take place. Please submit it to me (loki(a)fosdem.org) before Sat 3rd February by email, as plain text. The better structured, the easier it will be for us to encode the data ;) For each talk/activity in your devroom, we need the following information: * TALK: - - at what time the talk starts and when it ends (or the duration) - - the title of the talk/activity - - an abstract (1-2 lines that shortly explain the topic) - - a somewhat longer description (as long as you wish) - - optional: some HTTP links (related links, project website, blog, ...) * SPEAKER(S) (obviously, for each speaker): - - the full name of the speaker(s) - - if possible and if the speakers don't mind, also send us their email address (it will _not_ be disclosed and only _possibly_ used by us, e.g. to ask for the slides or such) - - an abstract for the speaker (e.g. "Homer Simpson is the lead developer on the Springfield Nuclear Power Plant project and contributes to a few other FOSS projects such as Futurama and Southpark") - - a somewhat longer bio of the speaker - - optional: a photo or a link to a photo - - optional: some HTTP links (website, blog, ...) As said, please submit it as plain text. Please send us the speaker abstract + bio in the 3rd form, e.g. "Homer Simpson is the lead developer..." instead of "I'm the lead developer...". Reference embedded URLs in abstracts and descriptions using the following form: "Homer Simpson is the lead developer on the [http://simpsons.name/springfield/ Springfield town] project."

Default gateway set incorrectly
by Theo Band [Xanadu Wireless] 09 Jan '07

09 Jan '07

I try to setup networking with a fresh CENTOS4.4 installation. Upto now I have 20 installations, most of them FC3/FC4 and RHEL3. I noticed that the default gateway is not setup properly when using Centos. [root@raaf ~]# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.101.0 * 255.255.255.0 U 0 0 0 eth1 169.254.0.0 * 255.255.0.0 U 0 0 0 eth1 default 192.168.101.1 0.0.0.0 UG 1 0 0 eth1 Networking is setup done by using dhcp, and this seems to work OK. Problem is however that the gateway should be 192.168.101.2 and not 192.168.101.1 (does not exist). If I manually add the gateway, networking is OK: route add default gw 192.168.101.2 eth1 [root@raaf ~]# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.101.0 * 255.255.255.0 U 0 0 0 eth1 169.254.0.0 * 255.255.0.0 U 0 0 0 eth1 default scholekster 0.0.0.0 UG 0 0 0 eth1 default 192.168.101.1 0.0.0.0 UG 1 0 0 eth1 (scholekster=192.168.101.2) If I issue "service restart network". The added gateway is removed again. I understand that I can fix this default gateway, but that is not what I want. I also tried to manually start dhclient: [root@raaf ~]# dhclient eth1 .... Listening on LPF/eth1/00:15:f2:******** Sending on LPF/eth1/00:15:f2:******** Sending on Socket/fallback DHCPREQUEST on eth1 to 255.255.255.255 port 67 DHCPACK from 192.168.101.2 bound to 192.168.101.221 -- renewal in 294560 seconds. But now my default gateway is added correctly! So is dhclient not used by the networking scripts?? Anyone got an idea of how I could debug this further? The reason I use eth1, is that the machine has two interfaces and is dual bootable. The FC4 installation seems to have a different idea of which adapter should be eth0... Thanks, Theo PS. The error message it started with, for google :-) [root@raaf ~]# yum update Setting up Update Process Setting up repositories http://mirror.centos.org/centos/4/updates/i386/repodata/repomd.xml: [Errno 4] IOError: <urlopen error (113, 'No route to host')>

Broadcast UDP on command line
by Jerry Geis 09 Jan '07

09 Jan '07

What command line command is available to broadcast a UDP packet on port 36? I can use a command like "nc -u -l -p 36" to listen to the responses but I can't figure out how to send out the broadcast packet for the devices to say "I'm here" back to me. THanks, Jerry
