freenx vs vmware console
by Les Mikesell 18 Jul '08

18 Jul '08

After upgrading to 5.2 and the current freenx, when I start the vmware server console (from VMware-server-1.0.6-91891) in the NX client I get Xlib: extension "XFree86-VidModeExtension" missing on display ":1000.0". in the terminal window where vmware was started and a black screen where the console of the virtual machine is supposed to be. Is there a way to make this work? I would normally ssh/freenx/vnc directly to the virtual machine but for the cases that need console access I would much rather use NX with the host machine with the vmware console conneced locally than use the vmware console remotely. -- Les Mikesell lesmikesell(a)gmail.com

Custom CentOS iso's
by Tracy R Reed 17 Jul '08

17 Jul '08

I have a consulting client who has a Linux based storage appliance which is based on Fedora Core 2. I'll pause here while you laugh... They need to upgrade to something more easily supported and CentOS is the chosen distro. They have the source RPM's for their old system stored in CVS and have a very weird/complicated build system to turn it all into an iso which I am still figuring out. They version control their source rpm's but don't really use CVS version numbers to number their distros. Instead they build an iso and name/number that and then have to keep the iso around forever. I want to go through their CVS, pick out the stuff we want to port to CentOS and trash the rest. And keep it all version controlled at the same time. The current thinking is that we want to get off of CVS and move to Mercurial. Given the above and that we want to customize our CentOS build what is the best way to do that? I am thinking we would like to work with the source rpm's. Putting binaries under version control which can just be built from the source seems silly. If we put the source rpm's and any associated build scripts in version control then given any particular repository version number we should be able to reproduce any installable ISO we created in the past. I am imagining that we will have a huge source tree of exploded SRPMS and we will go through the old CVS and evaluate all of the customizations they made and whichever are worthy can be hacked into the SRPMS, RPM's get built out of these, and an ISO gets built out of the RPM's. Does all of this sound feasible? Does CentOS already have tools for automating a complete iso build from an SRPM repository? Thanks! -- Tracy R Reed Read my blog at http://ultraviolet.org Key fingerprint = D4A8 4860 535C ABF8 BA97 25A6 F4F2 1829 9615 02AD Non-GPG signed mail gets read only if I can find it among the spam.

racoon and ipsec issues
by Bill Campbell 17 Jul '08

17 Jul '08

I am attempting to create an ipsec tunnel between two CentOS 5.1 systems, network-to-network with two different 192.168.xxx.0/24 LAN segments. I have gone through the documentation on the centos web site, and have the machines to the point where the /var/log/messages show ``IPsec-SA established'' on both machines after runnig ``ifup ipsec0'' (same ipsec0 on each machine). IP forwarding is configured in /etc/sysctl.conf and in the proper /proc ``file''. ``netstat -rn'' shows a reasonable looking route on each machine with the gateway as the private IP for the internal LAN. The iptables on each machine are totally clear with no filters. Attempting to ping the private interface on the remote machine results in this where the xx.xx... is the IP address of the public LAN. >From xx.xx.xxx.xxx icmp_seq=2 Destination Host Unreachable Running tcpdump on another Linux box on the remote network that is our main connection to the internet so sits between the remote machine and our T1 does not show any packets from the machine attempting to ping the remote or attempting to make an ssh connection to the remote machine's private IP. At this point I'm at a loss as what to try to debug this. My previous IPsec experience was with Freeswan on an older SuSE box which is quite different in the system setup. The centos/rh documentation is not totally clear what IP is meant by SRCGW, but looking at the ifcfg-ipsec script, it assigns the private IP of the internal network NIC if SRCGW is not set. I expected to see an ``ipsec0'' device from ``ifconfig'', as was done with freeswan, but either that's not the case with ipsec-tools or I have something hosed.

Difficulties with Seamonkey plugins on 5.2
by MHR 17 Jul '08

17 Jul '08

Has anyone else noticed this? I've been running a self-built, working 64-bit version of Seamonkey's 2.01a pre-release (alpha) version for the last six or seven months (because the "contributed" unofficial 64-bit build didn't work right and the official 32-bit release crashed all the time), and it's been working relatively well until recently, particularly in the area of plugins. After updating to CentOS 5.2, I noticed that the flash plugin didn't work right. This might be due to a major change in nspluginwrapper - it is now included in the CentOS (RHEL) release, as opposed to being a download from rpmforge. Problem is - it doesn't seem to work right. My flash plugin does not work. At all. There was a new official release of Seamonkey (1.1.10) with an available contributed 64-bit build (haven't gotten around to the 1.1.11 revision yet), so I though, maybe this time it will work better. I pulled down this revision and installed it. Works great - except for the flash plugin. (Actually, I only know that the acrobat reader plug-in works, but the flash plugin definitely does _not_.) I tried again with 1.1.11 here at work (32-bits) and it seems to work just fine. But, as of this morning at least, my home system absolutely does NOT work with the new nspluginwrapper, and the flash plugin does not work at all. This is true both on the 1.1.10 unofficial contributed 64-bit build, and also my home built 64-bit 2.01pre (with fresh source as of this morning). Does anyone have the new (0.9.91.5) nspluginwrapper working with the flash plugin on a 64-bit install of CentOS 5.2 and Seamonkey? Also, one of the "tricks" I learned with this whole setup was that the simplest way to "install" the plugins was simply to create symbolic links from /usr/lib64/mozlilla/plugins - I think that's right - to the relevant plugins directory. This worked until 5.2, or at least Seamonkey reports that the plugins are installed. (The AR8 plugin has serious problems, haven't gone all the way back to the AR7.9 plugin yet, and I haven't tested the mplayerplug-in yet, but the critical one is the flash plugin because so many web pages have flash videos on them these days.) Suggestions welcome. Thanks. mhr

Replacing custom kernel with another - with same identifier
by Antti J. Huhtala 17 Jul '08

17 Jul '08

Hi list, I just finished building a custom kernel from 2.6.18-53.1.21 source rpm - this time with ISA bus and ISAPNP support which I accidentally left out of my previous attempt. Unfortunately, this time I forgot to change my identifier in kernel-2.6.spec file. Thus I now have one *installed* kernel version *without* ISA support, and another one *with* ISA support but as rpm, not yet installed. Both kernels now have identical identifiers. What is the safe way to remove the previous installed kernel version without taking out the uninstalled new version? Is the latter safe in ~/rpmbuild/RPMS if I use 'rpm -e' to remove the former version? TIA Antti

gecko-libs dependency resurfaces
by Ben Mohilef 17 Jul '08

17 Jul '08

In doing an update of centos 5.2 this morning, I observed that the old gecko-libs dependency issue caused yum update to fail because it was required by nspluginwrapper (x64_86), devhelp, yelm and firefox. Also, a firefox (x64_86) showed the red hat splash screen rather than centos. Manual installation of affected rpms using --nodeps (I don't advise this) did not apear to impair the performance of any of the affected packages. Is everyone seeing this or do we have something missing in our installations? regards, benm

Simple IP Question
by Matt 17 Jul '08

17 Jul '08

I have a server located remotely running CentOS 5.x. I need to have two IP's on the same interface. So I have this: /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=none BROADCAST=69.x.x.199 HWADDR=00:x:x:x:c6:10 IPADDR=69.x.x.194 NETMASK=255.255.255.248 NETWORK=69.x.x.192 ONBOOT=yes GATEWAY=69.x.x.193 TYPE=Ethernet So I added this: /etc/sysconfig/network-scripts/ifcfg-eth0:0 DEVICE=eth0 BOOTPROTO=none BROADCAST=69.x.x.199 HWADDR=00:x:x:x:c6:10 IPADDR=69.x.x.195 NETMASK=255.255.255.248 NETWORK=69.x.x.192 ONBOOT=yes GATEWAY=69.x.x.193 TYPE=Ethernet Now the only IP that works is the second one. What am I doing wrong? Thanks. Matt
