CentOS 3 - Progress DB issue
by Tom Brown 03 Nov '06

03 Nov '06

Hi I have been given an issue with a progress box by one of our DBA's The issue is this.... /usr/dlc91d/bin> ldd _sqlsrv2 libprosqlsnd.so => not found libprosqlrds.so => not found libprosqlsnw.so => not found libprosqlgeneric.so => not found libprosqldb.so => not found libprosqlmm.so => not found libpronls.so => not found libprosqlss.so => not found libprosqljava.so => not found libprosqlos.so => not found librocket_r.so => not found libusort.so => not found libjvm.so => not found libhpi.so => not found libnsl.so.1 => /lib/libnsl.so.1 (0xb75c9000) libpthread.so.0 => /lib/tls/libpthread.so.0 (0xb75b8000) libcrypt.so.1 => /lib/libcrypt.so.1 (0xb758b000) libdl.so.2 => /lib/libdl.so.2 (0xb7588000) libstdc++-libc6.1-1.so.2 => /usr/lib/libstdc++-libc6.1-1.so.2 (0xb7546000) libm.so.6 => /lib/tls/libm.so.6 (0xb7524000) libc.so.6 => /lib/tls/libc.so.6 (0xb73ed000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0xb75eb000) does anyone know what package will provide those libs on a CentOS 3 box ? thanks

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 03 Nov '06

03 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.

CentOS 4: top default "solaris mode"

Is there a way to default "top" to Solaris mode for all users (without using a .toprc in every user's home dir)? We're not big fans of >100% CPU usage stats... Thanks. -- Alan Sparks, UNIX/Linux Systems Integration and Administration <asparks(a)doublesparks.net>

RE: [CentOS] mppe support in kernel-2.6.9-42.0.3.EL
by Ian Anderson 02 Nov '06

02 Nov '06

I would second this suggestion. We use OpenVPN to control access to our management network and it works really well. We currently manage over 50 people with VPN keys and the list is growing. The only drawback is that there isn't a very good web based GUI to administer your keys. When you have a security team consisting of 10 people, it can be a bit of a pain relying on bash scripts for key generation/revocation. -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of Alex Palenschat Sent: Thursday, November 02, 2006 1:39 PM To: CentOS mailing list Subject: RE: [CentOS] mppe support in kernel-2.6.9-42.0.3.EL > > MPPE required, but kernel has no support. > > > > Can anyone help me with getting this module for the 2.6.9-42.0.3.EL > > kernel??? > > > MPPE can cause you much heartache (as I learned the hard way > at my last > job...).

Using perl-Net-SSH-Perl with pubkey authentication under CGI.
by Will McDonald 02 Nov '06

02 Nov '06

Guys, I wonder if anyone can give me any pointers here, I hope it's CentOS related enough not to be too off topic, if it is then apologies. I'm attempting to setup a CGI which can connect to a remote system and execute a command. On the 'client', for the Apache user 'apache' I've given it a shell and generated a key-pair. I've configured Keychain [ http://www.gentoo.org/proj/en/keychain/ ] to load the keys for the apache user and make these persistently available via ssh-agent. I've setup a specific user 'cgissh' on the remote target system and configured its authorized_keys with apache@client's pubkey. >From the client system, running the following script from the shell returns the information I'd expect... [apache@webdev1 cgi-bin]$ cat perl-net-ssh-perl-test.pl #!/usr/bin/perl print "Content-type: text/html\n\n"; print "<HEAD><TITLE>Quick Test</TITLE></HEAD>"; $ENV{HOME} = "/var/www"; $ENV{USER} = "apache"; use Net::SSH::Perl; $sshhost='target'; $sshuser='cgissh'; $sshport='22'; $sshprotocol='2'; $sshdebug='1'; $sshcipher='3des-cbc'; $sshconn = Net::SSH::Perl->new($sshhost, protocol=>$sshprotocol, port=>$sshport, debug=>$sshdebug, cipher=>$sshcipher); $sshconn->login($sshuser); my($out,$err) = $sshconn->cmd('hostname'); print "<HTML>"; print "<BODY>"; print $out; print "</HTML>"; print "</BODY>"; It's definately using the pubkey information from Keychain as the target system ONLY accepts key-based authentication and I'm "su - apache"d to run the script so it's not picking up another users ssh-agent key info from the environment. Attempting to execute the same script as a CGI by accessing http://client/cgi-bin/perl-net-ssh-perl-test.pl results in the following in the logs...

If this was a shell script I'd have used '[[ -f $HOME/.keychain/$HOSTNAME-sh ]] && source $HOME/.keychain/$HOSTNAME-sh'. Additional info: Both systems are up-to-date CentOS 4.4 systems running the default Apache with perl-Net-SSH-Perl and its dependencies from RPMForge. Any pointers greatly appreciated. Will.

I'm not to experienced in Linux but I've done that (on 4.4) just let the downloader install it and type vmware. It'll point you to the config file and just follow the instructions, even a windows guy like me could do that, I was sorprised to find it run smoother than in Windows Server 2003. Now if I could just figure out how to export a directory in NFS 3, I could test ESX Server without the expense of SCSI <GRIN> Original Message ----------------------- hi could you please give me a notes to install vmware server on centos i will be thank full to you thanx _________________________________________________________________ Get today's hot entertainment gossip http://movies.msn.com/movies/hotgossip?icid=T002MSN03A07001 _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos
