I pretty much have this same setup. I don't have routing enabled is all. I configure each ethx device like they were on a single network. When your system is up and running, check the routing table, using route. It'll tell you which interface can reach which networks. My setup has 192.168.a.b/24 on eth0, 192.168.c.d/24 on eth1 and I can ping hosts on both networks. There's always a possibility I don't understand your question! :) Thanks!

Well, the way I configure my servers is that no data gets stored on an OS partition. Once the server is built, I create an image of it, and store it off on another machine. For any incremental changes, I use rsync to keep track of changes for the entire system. So, if a drive should die, I can pop in a new drive and restore with g4l. Then use the latest rsync backup to restore all the changes. I've done this on several occasions, and it works very well, even on systems with terabytes of data. The key is to keep data and OS software on seperate partitions, or better yet, drives. Thanks!

I've also written up a howto on this very subject. You can read about it here: http://marks-tech-pages.blogspot.com . I got started with mikerubel, and took it further. HTH Mark

howto compile wine on centos 4 and x86_64
by Jerry Geis 22 Nov '06

22 Nov '06

Hi all, I am trying to compile wine on x86_64 for 32 bit world. I found the fedora 5 wiki which states: ------------------------- Building Wine on Fedora Core 5 x86_64 Run the following commands as root: cd /usr/lib ln -s libfreetype.so.6 libfreetype.so ln -s libXext.so.6 libXext.so ln -s libX11.so.6 libX11.so ln -s libGLU.so.1 libGLU.so All the required development packages are available in the /core/ and /extras/ repositories. Run configure with: ./configure --x-libraries=/usr/X11R6/lib --x-includes=/usr/X11R6/include --with-x make depend make ---------------- however when I do this I get errors. make[2]: Leaving directory `/home/silentm/wine-0.9.25/libs/wine' make[2]: Entering directory `/home/silentm/wine-0.9.25/libs/wine' gcc -c -I. -I. -I../../include -I../../include -D__WINESRC__ -DWINE_UNICODE_API="" -D_REENTRANT -fPIC -Wall -pipe -fno-strict-aliasing -Wdeclaration-after-statement -Wwrite-strings -Wpointer-arith -g -O2 -D__i386__ -o casemap.o casemap.c In file included from ../../include/windef.h:234, from ../../include/wine/unicode.h:26, from casemap.c:4: ../../include/winnt.h:764:1: warning: "CONTEXT_CONTROL" redefined ../../include/winnt.h:719:1: warning: this is the location of the previous definition ../../include/winnt.h:765:1: warning: "CONTEXT_INTEGER" redefined ../../include/winnt.h:720:1: warning: this is the location of the previous definition ../../include/winnt.h:766:1: warning: "CONTEXT_SEGMENTS" redefined ../../include/winnt.h:721:1: warning: this is the location of the previous definition ../../include/winnt.h:767:1: warning: "CONTEXT_FLOATING_POINT" redefined ../../include/winnt.h:722:1: warning: this is the location of the previous definition ../../include/winnt.h:768:1: warning: "CONTEXT_DEBUG_REGISTERS" redefined ../../include/winnt.h:723:1: warning: this is the location of the previous definitio This seems to be due to the fact that __i386__ and __x86_64__ are both defined in winnt.h I looked elsewhere and they mention having to install libc6-dev.i386. I tried doing yum provides to try and find it but I cannot find it. Has anyone gotten x86_64 wine to build? Can you share your steps? Or what about this libc6-dev.i386 package? Thanks, Jerry

digikamimageplugins from Karan's repo
by Aleksandar Milivojevic 22 Nov '06

22 Nov '06

Hi, I've just installed digikam and digikamimageplugins from Karan's repo. The digikam package works nicely, however if I try to use any of the plugins from digikamimageplugins, digikam crashes complaining about unresolvable symbols, for example: digikam: symbol lookup error: /usr/lib64/kde3/digikamimageplugin_adjustlevels.so: undefined symbol: _ZN7Digikam16ImageGuideWidgetC1EiiP7QWidgetbi I've noticed that there's discrepancy in versions between digicam and digicamimageplugins (0.8.1 vs. 0.7.4) which I beleive is where the problem might be. Is there digicamimageplugins-0.8.1 RPM for CentOS? If not, I could probably easilly rebuild my own. Just wondering if somebody already did it. Thanks, Alex

Postgresql-8.1.4 RPMS for x86_64 and i386 now in the CentOS-4 centosplus repository
by Johnny Hughes 22 Nov '06

22 Nov '06

CentOS has moved the postgresql-8.1.4 RPMS for i386 and x86_64 into the CentOSPlus repository. (do not forget the compat-postgresql rpm as well) Please backup your postgresql-7.x databases prior to upgrading per this link: http://www.postgresql.org/docs/8.1/interactive/install-upgrading.html (backup data, install RPMS, /etc/init.d/postgresql restart, restore data) Thanks, Johnny Hughes
