Compling Apache 1.3.37 w/mod_ssl on x86_64 fails
by Mike 25 Oct '06

25 Oct '06

This procedure works fine for years on RH/CentOS 3+ The current machine is a core 2 duo with x86_64 CentOS 4.4 (updated) Compile, make and install openssl in /usr/local/openssl configure mod_ssl for apache 1.3.37 configure apache using SSL_BASE=/usr/local/openssl SSL_INCDIR=/usr/local/openssl/include SSL_LIBDIR=/usr/local/openssl/lib ./configure --with-layout=Apache --prefix=/usr/local/apache --enable-module=most --enable-shared=max --enable-module=ssl make dies here: gcc -L/usr/local/openssl/lib -shared -o libssl.so mod_ssl.lo ssl_engine_config.lo ssl_engine_compat.lo ssl_engine_ds.lo ssl_engine_dh.lo ssl_engine_init.lo ssl_engine_kernel.lo ssl_engine_rand.lo ssl_engine_io.lo ssl_engine_log.lo ssl_engine_mutex.lo ssl_engine_pphrase.lo ssl_engine_vars.lo ssl_engine_ext.lo ssl_scache.lo ssl_scache_dbm.lo ssl_scache_shmht.lo ssl_scache_shmcb.lo ssl_expr.lo ssl_expr_scan.lo ssl_expr_parse.lo ssl_expr_eval.lo ssl_util.lo ssl_util_ssl.lo ssl_util_sdbm.lo ssl_util_table.lo -lssl -lcrypto -L/usr/lib/gcc/x86_64-redhat-linux/3.4.6 -lgcc /usr/bin/ld: /usr/local/openssl/lib/libssl.a(s2_srvr.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC /usr/local/openssl/lib/libssl.a: could not read symbols: Bad value collect2: ld returned 1 exit status make[4]: *** [libssl.so] Error 1 make[3]: *** [all] Error 1 make[2]: *** [subdirs] Error 1 make[2]: Leaving directory `/downloads/apache_1.3.37/src' make[1]: *** [build-std] Error 2 make[1]: Leaving directory `/downloads/apache_1.3.37' make: *** [build] Error 2 It seems there's something wrong with mod_ssl on 64bit OS, but yet I see RPM's that claim to work (haven't tried). I have googled for hours but haven't found anything helpful. Anyone out there familiar with this issue and it's resolve? Thx

Hi, I run a fully updated CentOS 4.4 machine. This morning I got the errors below in my daily Logwatch report (Sendmail part). What has happend? Just some new bogus spammer that cant get the protocol right or is the server under attack? I have googled around but cannot fins any answer or I just suck at googleing... Any ideas ?

Also, the use of spamcop should (in my opinion) be suggested with a caveat that the user read up on their own description of their criteria for blocking mail. I have seen large email providers and even ISPs etc blocked by this list, even if temporarily. Just my 2 cents, Alex

detecting ECC errors?
by Christian Nygaard 25 Oct '06

25 Oct '06

How do you detect ECC memory errors when CentOS is booted? Just had a strange hardware error where a server machine hang during anaconda install it passed memtest86 test but the bios dmi log showed dimm bank 1b had failures. Now I wonder what would happen if a machine running in production would get such problems, how do you detect it without having to go into bios? Hints on what to use? Chris

Gnome's profiles tool?
by Jordi Espasa Clofent 25 Oct '06

25 Oct '06

Hi all, I'm looking for a tool to create and manage the users' profiles in GNOME desktop environment. I've searched Pessulus (included in GNOME admin tools by default according GNOME docs) whitout success. I've tried to compile Sabayon (the CentOS rpm is not avaiable I think) but there are a lot of dependencies to resolve. ¿Any ideas? Thanks in advance. -- Jordi Espasa Clofent PGP id 0xC5ABA76A #http://pgp.mit.edu/ FSF Associate Member id 4281 #http://www.fsf.org/

Help request...recovering LVM on centos 4.2
by Sanjay Arora 24 Oct '06

24 Oct '06

I installed a Centos 4.x system using a lvm install across four HDDs. It is my first install using LVM. System had a power-failure and stopped booting up. A new trainee simply took out the HDDs and restarted the file-server on a fresh HDDs. Now the problemis that the four HDDs have data. But the order of the HDDs (of install....1st primary, 2nd primary etc.) is unknown. Earlier we used to boot with knoppix live cd and recover data through rsync. Knoppix is not automatically recognizing lvm partitions. My query is to ask for step by step instructions on finding & mounting my lvm partitions correctly using knoppix or installing earlier hdds one by one in the new file-server & restoring data to users. Pointers on any howtos or detailed examples of recovery would also be appreciated. With best regards. Sanjay.
