I am running a Xen installation on a Centos-4.4 based test box, my desktop unit, and I am having intermittent problems installing certain pieces of software. Some time back I posted to this list regarding my inability to install Adobe Acrobat on this unit and was advised to essentially repackage the software and try again. This is beyond my present means of knowledge or time to acquire same and

In short, the reason considering (and still only considering) turning it off is to make tripwire usable again (security vs. performance, I guess). Is it possible to completely turn it off system-wide? Any additional steps needed on the existing system (that already have half of the binaries prelinked)? What order of performance degradation to expect? If it is minor, nobody is going to cry about it. My old RH 7.3 systems don't have prelinking, and I don't see them being any slower than FC2 and newer systems that have prelinking... ---------------------------------------------------...

What are the pros and cons of disabling prelinking in CentOS 4? From what I understand, prelinking is ment to be performance improvement (faster loading time for binaries). I can see some potential benefit on workstations where many different processes are started frequently. But how big is that benefit in real life? Would I slow do...

Hi, I am using Debian GNU/Linux Lenny with kernel verison 2.6.26-2-amd64 (x86_64) and want to compile wine 1.1.38 form the source Tarball. After successful compilation and installation through "make install", I get the following error when trying to run wine (e.g. when trying to run winecfg or any other application). wine: failed to initialize: /usr/local/lib/wine/ntdll.dll.so:

I have a large installer program (~400MB) that fails to run under wine (20050310). It gives me the following: err:virtual:map_image Image was mapped at 0x60640000: standard load address for a Win32 program (0x00400000) not available err:virtual:map_image Do you have exec-shield or prelink active? wine: could not load L"C:\\WebPACK_71_fcfull_i.exe" as Win32 binary The thing is that I don't seem to have either (exec-shield or prelink). The /proc/sys/kernel/exec-shield entry isn't present, and prelink isn't intalled. Other programs run fine. What's the pro...

The current /lib/tls support in Xen/Linux through rewriting faulting instructions seems to work well, but for one rather nasty issue. If you are running with /lib/tls on a system that also uses prelinking (you can check this by looking for e.g., /etc/cron.daily/prelink) then you''re /lib/tls libraries will get corrupted! The problem is that the prelinking changes cause some of the binary patches to also get flushed out to disc. It''s a particularly nasty bug because you will not...

Hey, Gang! To ensure that a file hasn't been corrupted or tampered with, you can use rpm to verify the package it came from. Well, I found this: rpm -Vv util-linux .... ........ /usr/bin/cal S.?..... /usr/bin/chfn ........ /usr/bin/chrt S.?..... /usr/bin/chsh .... Does anyone else get this? And what would be the proper course of action at this point? Thanks mucho. --

The above discussion of prelink gave me pause for thought... I have a "suite" of programs that I install in their own directory, along with their datafiles, under /opt. Would it be a good idea to add that directory to /etc/prelink.conf? What could go wrong? -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilleth...
