With sudo you can water down the ability of a user, eg can't use the shutdown command. I don't know if you can disable su -, but that would be the plus of this style. -- Best Regards, Justin Bull So Hip it MHz Studios www.sohipitmhz.com http://www.sohipitmhz.com/pubkey.txt (PGP Public Key) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

You should install an Intrusion Detection System (IDS) as they are great tools to assist you in how the crackers are gaining access into your system. We see load averages of 500+ and see people from all over the world logging into our server (used last). If I understood you correctly, you're saying that running the last command shows logins worldwide that are not yours? Immediately suspend / disable / lockdown the accounts they're logging into if they're not important (say a user thats only used for a daemon). If I were you I would immediately set up keys for your ssh, disabling root ssh login (you can gain root via su - or sudo once you login), and only enable protocol 2 for ssh. Install an iptables frontend like APF to help you ban malicious IP addresses. Are you running the latest version of CentOS? Make sure they don't have a critical exploit like a kernel privilege escalation exploit. -- Best Regards, Justin Bull http://www.sohipitmhz.com/pubkey.txt (PGP Public Key) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] x86_64 CentOS 5.3 Users - Library Issue
Hello, I need to conduct a little research. Anyone who is running CentOS 5.3 x86_64 please run the following: # yum install libxml2-devel # nm /usr/lib64/libxml2.a | grep xmlXPathContextSetCache If my suspicions are correct, if you run cPanel/WHM you will not see any output and if without cPanel/WHM you'll see something similar to this: 23a0 T xmlXPathContextSetCache Thanks for your time and help. -- Best Regards, Justin Bull http://www.sohipitmhz.com/pubkey.txt (Public Key) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

As far as I know you just run the following command as root: # mount -t ntfs-3g /dev/sda1 /mnt/windows Where /dev/sda1 is the location of your USB media and /mnt/windows is where you want your mountpoint to be. The hard drive shows in GUI, but doesn't open or mount as I expected. I didn't see you run the above mount command, what did you do to mount the device? -- Best Regards, Justin Bull http://www.sohipitmhz.com/pubkey.txt (Public Key) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Source RPM issues. Mismatched Libs?
Hello, I am having some issues with the installation of the Icecast2 software on my CentOS 5.3 x64 machine. I am attempting to install from a source RPM provided by the developer. Upon executing: # rpmbuild --rebuild icecast-2.3.2-0.src.rpm Normal compilation takes place until the following error is thrown out: /usr/lib64/libxslt.so: undefined reference to `xmlXPathContextSetCache' I've done some research and found others have a similar issue. It appears this is only isolated with CentOS 5.x x64 builds and, according to the Icecast2 developer, is due to a mismatch between libxml2 and libxslt. My machine is a brand new install and is updated from the official mirrors. libxml2-devel and libxslt-devel are installed and are at their latest version (2.6.26-2.1.2.7.x86_64 and 1.1.17-2.el5_2.2.x86_64 respectively at the time of this writing). For anyone who is interested in reading up on this, here are the Icecast2 threads related to this issue: http://icecast.imux.net/viewtopic.php?t=4851 http://icecast.imux.net/viewtopic.php?t=6506 http://icecast.imux.net/viewtopic.php?t=6210 I do apologize if I've made any formating mistakes and/or incorrect posting etiquette to the mailing list, as it is my first time using one. -- Best Regards, Justin Bull http://www.sohipitmhz.com/pubkey.txt (Public Key) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
