CentOS on Dell Inspiron 640m laptop
by techlists＠comcast.net 03 Nov '06

03 Nov '06

I ordered and just received today a new Dell Inspiron 640m laptop (it also goes by the name E1405). Anyone tried installing CentOS on this laptop? It's the wireless drivers I'm most concerned about; it's got the Dell 1390 internal wireless card (not the Intel wireless). Anyone have some feedback, on the wireless or any other issues, on running CentOS on this laptop? Thanks Paul

CentOS 4.4 and other software?
by Scott Ehrlich 03 Nov '06

03 Nov '06

I just installed CentOS 4.4 on my laptop, having good experience with Debian, Fedora Core 5, and RHEL4. I really like 4.4's overall appearance (meshing of RHEL4 and FC5), but what I have yet to figure out is how to access repositories for applications that are not part of the default install, such as ncftp. I invoked and updated yum, but it had no idea. I would also like to see what all available kernel offerings are, and maybe various development tools (i.e. dependencies). Up2Date didn't seem much of a help, either. None of the above tools seemed to know anything about ncftp, and it has been around for at least 10 years, and is available for just about every distro, sometimes by default. Am I missing something with available packages? Thanks. Scott

In my case, I have about 3TB of data that needs to be backed up, and taken offsite. So, the only real option is rsync going out to disks. We started out with using one of the recipes from the Linux Server Hacks book, #38, #41 & #42 to essentially build up a poor man's SAN. Using CentOS installed on systems with 3Ware cards, I have 2 onsite 4 TB NAS. The first one is for network use, the second is for hourly, daily and weekly snapshots of the main NAS. There's a third 4TB NAS that's located offsite in a colo facility that's fed with dual T1s. We can have anywhere from 2-5 GB of data change every day. We're a company of about 50 employees, and we do legal work - so nothing can be thrown away. This system runs 7 days a week, and it's fully automated with email alerts, etc. The big benefit is restores. We've had our graphics dept accidently delete 250GB of data, and it was trivial to scp the missing data back to the main NAS. It all happened at network speeds, over a GB switch. All the NASes have dual NICS in them, and the second NICS are connected to their own private GB switch - hence the poor man's SAN. When hourly snapshots run, all the data that changes has a seperate GB network to move the data, leaving the office network alone. No user can tell that backups are happening throughout the day. Maybe this is something I should write up in more detail. The entire system runs on just a couple of shell scripts, rsync, and Perl program to mail out logs.... HTH Mark Mark

I had a chat with someone from RedHat at LinuxWorld Boston about this. Sounded like it was something they were hearing a lot, but hadn't figured out how to address. In my case, I'd like to be running sendmail 8.13.x so as to be more up-to-date on milter compatability, but didn't want to be dealing with having to build RPMs and play the dependency issue game from there. While it's true the next major release will incorporate the newer sendmail, the selling point of longer-term support is then nullified some. It's nice to stay on a relatively stable release and NOT have major upheavals in the entire platform so often, but it would be powerful to couple that stability with the ability to easily update key componentry in just one or two areas. That way, you could have something very stable for a platform base, plus the one newer component needed for a server's core function (web-related in the case of the poster here, email-related in my case). Hopefully in the future there will be a way to deal with this.

-all-static problems when linking apps which require -lpthread and -lc
by Alexey Loukianov 03 Nov '06

03 Nov '06

Hello all, I used to use fully statically linked PHP, which I build into RPM using own-written spec-file. I need to do this as there are a lot of boxes with old linuxes (RedHat 6.2, 7, 9) which I can't upgrade to CentOS3/4 right now for a several reasons I don't want to explain here. When I've been using CentOS 4.0 and 4.1 - there were no big problems to link PHP as static executable (i.e., when ldd says that "php not a dynamic executable"). All I have to do, is: LIBS="`pkg-config openssl --libs` `pkg-config --libs libxml-2.0` -lungif -lstdc++" \ LDFLAGS="-static -static-libgcc" \ CFLAGS="`pkg-config openssl --cflags` $RPM_OPT_FLAGS" \ ./configure ..... and LDFLAGS="-all-static -static-libgcc" \ CFLAGS="`pkg-config openssl --cflags` $RPM_OPT_FLAGS" \ make %{?_smp_mflags} It was sufficient to successfully compile totally static executable. After up2dating my compile box to CentOS 4.3 I receive following errors when trying to link PHP statically: ... ....(cuted a lot of lines and minor warnings).... .... /usr/lib/libpthread.a(lockfile.o)(.text+0x0): In function `flockfile': : multiple definition of `_IO_flockfile' /usr/lib/libc.a(flockfile.o)(.text+0x0): first defined here /usr/bin/ld: Warning: size of symbol `_IO_flockfile' changed from 30 in /usr/lib/libc.a(flockfile.o) to 18 in /usr/lib/libpthread.a(lockfile.o) /usr/lib/libpthread.a(lockfile.o)(.text+0x0): In function `flockfile': : multiple definition of `__flockfile' /usr/lib/libc.a(flockfile.o)(.text+0x0): first defined here /usr/bin/ld: Warning: size of symbol `__flockfile' changed from 30 in /usr/lib/libc.a(flockfile.o) to 18 in /usr/lib/libpthread.a(lockfile.o) /usr/lib/libpthread.a(lockfile.o)(.text+0x14): In function `funlockfile': : multiple definition of `_IO_funlockfile' /usr/lib/libc.a(funlockfile.o)(.text+0x0): first defined here /usr/bin/ld: Warning: size of symbol `_IO_funlockfile' changed from 30 in /usr/lib/libc.a(funlockfile.o) to 18 in /usr/lib/libpthread.a(lockfile.o) /usr/lib/libpthread.a(lockfile.o)(.text+0x14): In function `funlockfile': : multiple definition of `__funlockfile' /usr/lib/libc.a(funlockfile.o)(.text+0x0): first defined here /usr/bin/ld: Warning: size of symbol `__funlockfile' changed from 30 in /usr/lib/libc.a(funlockfile.o) to 18 in /usr/lib/libpthread.a(lockfile.o) /usr/lib/libkrb5.a(cc_file.o)(.text+0x1add): In function `krb5_fcc_generate_new': : warning: the use of `mktemp' is dangerous, better use `mkstemp' collect2: ld returned 1 exit status make: *** [sapi/cli/php] Ошибка 1 As you can see, the trouble is that there are same functions defined in main glibc lib and in libpthread: [root@cappa SPECS]# nm /usr/lib/libc.a --defined-only 2>/dev/null | grep flockfile flockfile.o: 00000000 W flockfile 00000000 T __flockfile 00000000 T _IO_flockfile [root@cappa SPECS]# nm /usr/lib/libpthread.a --defined-only 2>/dev/null | grep flockfile 00000000 W flockfile 00000000 T __flockfile 0000003c T __flockfilelist 00000000 T _IO_flockfile So, the question is: what the hell?! Are there any ways to successfully compile PHP statically on CentOS4.3 box? And why the hell are this functions defined in both libc and libpthread, making impossible to link any programme statically when using both glibc and nptl? Of course, I can downgrade my compile-box to CentOS 4.1 or 4.0, but that wouldn't be cool as I'll loose any bug-fixes made to general libs in 4.2, 4.3 and following. So I dislike it . Thanks in advance. P.S.

Apache 2.2X
by Tim Uckun 02 Nov '06

02 Nov '06

Hello All. I am trying to set up a rails+mongrel+mod_proxy_balance application. Unfortunately the stock apache install on centos is the 2.0 series which does not support mod_proxy_balance. I could not find the 2.2X RPMs on dag or dries either. Is there a yummy way to upgrade to the 2.2 series of apache? I tried with the individual RMPS but no joy there due to comples web of dependencies.
