USB key installed OS; file system goes read-only randomly...

10 May '10

This happened a few times now, I (soft) reboot and do the fsck thing and all is fine until it happens again. Any ideas?

which gcc package?
by Michael Klinosky 09 May '10

09 May '10

Hello. I tried to compile a program (plugger), but I don't have *any* sort of compiler installed. This is on Cent5.3. So, I used Package Manager, concentrating on gcc. But, it seems that I have a choice, thus: gcc-4.1.2-46.el5.i386 gcc-4.1.2-46.el5_4.1.i386 gcc-4.1.2-46.el5_4.2.i386 gcc-c++-4.1.2-46.el5.i386 gcc-c++-4.1.2-46.el5_4.1.i386 gcc-c++-4.1.2-46.el5_4.2.i386 ... along with some others (Fortran, Ada, Java, and Obj-C). I'm thinking that I need only 1 'flavor' (say, gcc-4.1.2-46.el5.i386 and gcc-c++-4.1.2-46.el5.i386) - correct? I tried a google.com/linux search - the only link that seemed helpful was http://gcc.gnu.org/ -- where I found only this: "The core distribution includes the C language front end as well as the shared components." I have no clue which package would be the FE, and what the shared components are. Perhaps 1 of those packages is the core?

Broken upgrade to memcached
by m.roth＠5-cent.us 09 May '10

09 May '10

Yum checkupdate tells me I should update memcached, that the x86_64 1.4.5-1.el5 needs an update, I go to do that, and it complains that it's missing a dependency of libevent-1.4.so.2 (this is all 64 bit, CentOS 5.4). Clues... or is this actually broken? mark

08 May '10

Hi all, Not having much luck adding a user to more then 1 group in OpenLDAP thats provided in Centos. Any suggestions to have the outcome of having a user belong to multiple groups? Should I create a new group that has multiple GIDs and assign a user to that new group? If so, how? :) Thanks in advance.

Apache Tomcat/5.5.23
by testwreq wreq 07 May '10

07 May '10

I have a new instllation of tomcat on centos. My $CATALINA_HOME is /usr/share/tomcat5 and tomcat is running. http://localhost:8080 brings up the tomcat page & one of the option is "Administration". I would like to use this web interface and even give some of the test webapp users ability to restart tomcat. According to the home page, users are defined in $CATALINA_HOME/conf/tomcat-users.xml. Currently my file has the following content more tomcat-users.xml <?xml version='1.0' encoding='utf-8'?> <tomcat-users> <role rolename="tomcat"/> <role rolename="role1"/> <user username="tomcat" password="tomcat" roles="tomcat"/> <user username="both" password="tomcat" roles="tomcat,role1"/> <user username="role1" password="tomcat" roles="role1"/> </tomcat-users> I tried logging to the administration web interface with tomcat/tomcat but it did not work. Can anyone guide to configure this file? I am very new to tomcat. Thank you.
