I am getting glibc errors

[Tenaka]

I do not know anything about this, so I`ll post some lines from my logfiles:

Any idea how to track this error down and remove?

What OS and version are you running?


What version of glibc is it? Please post the output of one of the following:

RedHt/Fedorea:

# rpm -qa | grep -i glibc

or

# rpm -qa | grep -i libc6

or something...


Debian:

# dpkg -l libc6

Did you manually upgrade that at some point? On my 3.1 box I have version 2.3.2.ds1-22...


Check out this forum... your not the only one having those issues with libc6 2.3.5*... http://www.linuxquestions.org/questions/showthread.php?threadid=349135

[Tenaka]

I already googled around, I remember seeing that post too, but as I have not programmed anything, using only ready - made packages (almost) I thought no longer about this issue...

I guess I'll try a downgrade tonight but I do not remember who or what programm requiered newer version of libc6...

[Tenaka]

if I downgrade to that version with apt-get install libc6=2.3.2.ds1-22 there are a lot of packages marked for removal.
How would I also mark those dependencies for downgrade ?

While waiting for help I will upgrade libc6 to its unstable version which will only upgrade 2 more packages to unstable, maybe the problem is solved with the never package!?

the upgrade helped with ftp uploads, it no longer disconnects me when uploading but when trying to list a remote folder it still gives glibc errors...

any suggestion on how to downgrade libc6 and its dependencies? or might an upgrade of proftpd help?

[Tenaka]

to revive that old post:

I did not succeed in downgrading, upgrading did not help.

maybe someone can help here:

if I downgrade to that version with apt-get install libc6=2.3.2.ds1-22 there are a lot of packages marked for removal.
How would I also mark those dependencies for downgrade ?

[falko]

To be honest: it's not the best idea to upgrade/downgrade glibc, because too many programs rely on it. If you do it nevertheless, chances are good that you mess up your system.

If it is not a production system, I'd suggest that you re-install the system from the beginning.

[Tenaka]

ok I udnerstood that but is it technicall ypossible?

i.e. If I upgrade a package, packages relying upon it are automatically marked for upgrade as well, but if I downgrade a package the packages depending on it are marked for deletion instead, so how would I go about this if I would want to do it?

[falko]

I've never been able to upgrade/downgrade glibc without getting dependancy errors, so - theoretically it should be possible, practically it's more than difficult... :(

[agelospanagiotakis]

i get these error too on ubuntu 6.06 LTS dapper drake! :mad:

Where are you getting these errors?


I had a issue a few weeks ago where a box had a mismatched version of ZendOptimizer and PHP. Basically, Zend was causing the glibc error, and Apache was segfaulting. If it is related to Apache/PHP, try the following:


php < /dev/null


You should get no output. However, if you get the glibc error, then it is related to PHP. Uninstall Zend, re-install the proper version:

PHP 4.x -> ZendOptimizer 2.6.x
PHP 5.x -> ZendOptimizer 3.x


Or something like that... if this is even related to PHP/Apache...

[agelospanagiotakis]

with
php < /dev/null
i get no errors
my PHP is versioned 5.1.2

i have apache
Server version: Apache/2.0.55
Server built: May 29 2006 01:52:53
installed

i recently installed ISPconfig..... and then my server on the address
https://________:81/
can not go from main ISPConfig page (index.php) to login.php (wants me to download a file named login.php ) - witch is empty!
the apache log file is posted in my prev post

[agelospanagiotakis]

i forgot to mention that the end of a NOT FOUND web page
I GET THESE:

Apache/2.0.55 (Ubuntu) mod_auth_kerb/5.0-rc6 DAV/2 SVN/1.3.1 mod_fastcgi/2.4.2 mod_jk/1.2.14 mod_ldap_userdir/1.1.8 mod_mono/1.1.10 mod_python/3.1.4 Python/2.4.3 proxy_html/2.4 mod_ruby/1.2.5 Ruby/1.8.4(2005-12-24) mod_ssl/2.0.55 OpenSSL/0.9.8a

SOULDN'T there be a mod_php ( parammeter) ?
i know that ISPConfig makes it not default to apache.
so i guess the error is from ISPConfig , right ?

[falko]

You're mixing things up.

Apache/2.0.55 (Ubuntu) mod_auth_kerb/5.0-rc6 DAV/2 SVN/1.3.1 mod_fastcgi/2.4.2 mod_jk/1.2.14 mod_ldap_userdir/1.1.8 mod_mono/1.1.10 mod_python/3.1.4 Python/2.4.3 proxy_html/2.4 mod_ruby/1.2.5 Ruby/1.8.4(2005-12-24) mod_ssl/2.0.55 OpenSSL/0.9.8acomes from your main Apache, not from the ISPConfig Apache (ISPConfig comes with its own Apache that serves the ISPConnfig web interface on port 81).

If the ISPConfig Apache doesn't serve the ISPConfig interface correctly, then there's something wrong with ISPConfig's PHP.
What's the output of ls -la /root/ispconfig/php? What's the output of /root/ispconfig/php/php -v?

[agelospanagiotakis]

well the problem was solved .... i uninstalled everithing
firstly ispconfig , then mysql and then apache/php ... then installed again.
thanks anyway!
now the cmd promt returns

What's in Vhosts_ispconfig.conf?

[agelospanagiotakis]

the file
/etc/apache2/vhosts/Vhosts_ispconfig.conf
is empty....

is that so bad ?

[falko]

That means that your vhsot configuration wasn't written. What's the output of ls -la /etc/apache2/vhosts?

[jeffrey.moncrieff]

I have setup one of clients with ispconfig. Evey thing seems to work but I am get a error Message when we boot up the node like

You should have installed ProFTPD instead of vsftpd, as described in this tutorial: http://www.howtoforge.com/perfect_setup_ubuntu_6.06

ISPConfig has better support for ProFTPD than for vsftpd.

[djtremors]

I'm getting this same problem. I did install vsftpd and then was hoping after ispconfig installed I could just change it in the gui.. i guess not.

/etc/init.d/ispconfig_tcpserver start

Any way around this now? What is actually causing the error so I know where to fix/replace this?

thx

[djtremors]

ok, easy fix (i hate when i dig 1 minute later and find the fix)...

removed the old traces of vsftp.conf files......
