Hi People, The Linux Environment I am responsible for is using ssh key pairs to allow access to a number or accounts on a number Linux Servers. I currently have the opportunity to re-design some of this. So I would like to tap into peoples experiences to see what might be some good changes to make. Specifically I have a couple of questions 1. Currently all of the key pairs we are using

My server is supposed to be using ntp, with nothing changed from the defaults set up by CentOS5. However, daily I see log entries like Total synchronizations 2 (hosts: 2) **Unmatched Entries** sendto(193.6.222.20) (fd=21): Invalid argument: 1 time(s) sendto(141.89.226.2) (fd=21): Invalid argument: 1 time(s) Does this mean that ntp is failing? I assume so, and if so, how do I change

Hi folks, I have set up a cluster on CentOS 5.2 using /etc/cluster/cluster.conf - and it works fine. It's only purpose is to switch a virtual IP between two routers. Now the service is running, I can ping the virtual IP from outside - but this virtual IP is not bound to any interface. How does this work? Can I force the cluster to bind it to a certain interface? I need this because the

Mounting the /nfs4exports/share appears to be successful and the information displayed about partition size and free space seem correct but if I try to do anything inside the mounted directory the client will just hang.

Hi, In a recent security review some systems I manage were flagged due to supporting "weak" ciphers, specifically the ones listed below. So first question is are people generally modifying the list of ciphers supported by the ssh client and sshd? On CentOS 6 currently it looks like if I remove all the ciphers they are concerned about then I am left with Ciphers

Yum using proxy that requires authentication and a Password that contains the two characters \/ fails normally I can get yum to work with a proxy that requires authentication when required by doing something like http_proxy=http://<my username>:<my password>@<proxy server>:<proxy server port> export http_proxy or by filling in the appropriate information in yum.conf.

Hi People, I have just started building my own RPMS on both Fedora and CentOS and generally things have gone well. Currently I am trying to create RPMS for some commercial software that we have purchased. Step 1 was install the software using its JAVA Based installer ensuring that all files were installed into a particular directory in /usr/local. Step 2 was create a tar file of the

Hi, I am trying to get a CentOS 6 system relaying mail via my G-Mail account. I followed the instructions found at https://www.zulius.com/how-to/set-up-postfix-with-a-remote-smtp-relay-host/but there seems to be a problem with authentication.

Hi, I am trying to create a custom initrd that will work with PXE Booting on CentOS release 4.5 (Final) and Fedora Core 6. Can anyone point me to some documentation that will help with this ? The specific situation is that we have received some machines that need the latest e1000 Driver from Intel in order to detect the network card. If I install the systems without network and then do

Hi People I am trying to build a piece of software from source in this case aide 0.13.1 using this config line ./configure --with-zlib --with-selinux.

Hello, I work for a school in a New Zealand university and we are wanting to implement Server Virtualization for both CentOS and Windows systems. So I thought I would ask here what experience people have had with this and what issues that you all think should be considered? From my own research it seems that VMWare or Xen are really the two major products to be considered, are there any

Hi I use yumdownloader occasionally to grab RPMS. One thing that confuses me though is the --source option. I thought this would mean rather than getting the RPM that it would retrieve the source RPM. But it appears this isn't the case. Can anyone explain what this option actually relates to ?

Hi Everyone I am wondering if many people are using software that acts as a password safe. And if so can you recommend any software in particular? I know many people will disagree with this idea, and I myself have always followed the printed list stored in a secure location. But in our particular situation keeping this single list current and correct while ensuring that regular password

Hi People, I know this may seem off topic, but I thought for those of us who might have Debian users generating key pairs that they put on CentOS systems people should be aware that everybody who generated a public/private keypair or an SSL cert request on Debian or Ubuntu from 2006 on is vulnerable http://it.slashdot.org/it/08/05/13/1533212.shtml

Hi Everyone, I am currently reviewing the DNS records for the organization I work for and have one area I would like other peoples thoughts on. Would there ever be a situation where you need to have multiple A records pointing to the same IP Address? Currently we have a small number of cases where one IP Address has multiple A Records. This seems like a bad idea to me and I would replace

Hi, Today I have updated a CentOS 6.8 system that has MariaDB-server installed from http://yum.mariadb.org/5.5/centos6-amd64 and found that I had an SELinux issue. I know this is not really CentOS related, but thought I would check if anyone else on this list uses this repository and has also seen a problem ? Using the information at https://wiki.centos.org/HowTos/SELinux I have created a local

Hi, I am trying to install CentOS 5.2 on a Dell PowerEdge R905, and a problem that you run into is that the DVD Drive on the system is not recognized by the kernel. I have done some searching on the web and found http://kbase.redhat.com/faq/FAQ_103_13121.shtm and obtained the driver disk that it mentions. Having followed the instructions I can see and select the driver disk image but the
