Hello: I just did a fresh install of CentOS 6.2 on a virtual server. I am trying to configure Postfix but it does not seem to be reading configuration directives from /etc/postfix/main.cf Here is what I did to test it: vi /etc/postfix/main.cf and set this directive: myorigin = hello.world.com postfix reload postconf -d | grep myorigin I get this output: append_at_myorigin = yes myorigin =

Hello: I am using a CentOS server as a KVM host using bridged networking for the guest servers. I would like to limit the bandwidth available to a guest. I tried using the tc command, but it is only limiting the download speed to the guest. Is there a way to limit the upload speed from the guests?

just to follow on my earlier post, i have pointers to a couple commercial C/W manuals for RHEL administration, but both of them use an entire chapter discussing virtualization using Xen. i'm under the impression that RH is firmly in the KVM camp (at least for now), and that learning Xen on red hat/centos wouldn't be as useful as learning KVM. thoughts? rday --

Adobe doesn't seem to have acroread for x86_64 linux, or at least I don't see it anywhere. Anybody know otherwise? Evince and other tools work pretty well, but I have always liked having the "real thing" around for those occasions when they don't. -- ---- Fred Smith -- fredex at fcshome.stoneham.ma.us ----------------------------- I can do all

Are "centralized" database (SQL) servers best left out of virtualization and committed to their own hardware like the "old days" or are there some guidelines one should consider in setting them up? I'm not talking mega-large recordsets, but large enough to handle multiple years of CRMs and intensive querying, Accounting Systems and so forth. Fundamental website CMS

http://www.realvnc.com/products/enterprise/4.1/ipv6.html IPv6 support in VNC Server E4.1.7/P4.1.2 VNC Server E4.1.7 & P4.1.2 are fully IPv6-aware, but is shipped with IPv6 support disabled by default, for security reasons. IPv6 can be enabled by setting "InTransports=IPv6,IPv4" (the default being IPv4 only), either on the command-line when starting vncserver under Unix Ok.

I have always been able to browse, without any problems, http://www.mobile-review.com/index-en.shtml but for the past 2 or 3 days, Mozilla Firefox just hangs "connecting to ...." How can I tell if they have started blocking IP addresses from Colombia? I would like to do that, before I post to the IPCop mailing list.

First, I'm trying to following along on a document on "SecurityFocus" on "Securing MySQL: step-by-step". I'm on step 3.8 "Test the configuration". I have my CHROOT directory structure setup and the chrootuid is failing (haven't figured that one out, yet). So, I simply tried a 'chroot /chroot/mysql' and got: chroot: cannot run command

Hi All, I have a CentOS 5.4 web server. I have some stuff that runs on 443. When I hit https://<the site> The user gets a warning saying that site identity could not be verified and the user can add an exception if they want. How do I stop this from happing?

My 12 year old wants to learn more about servers and has memorized a lot of commands like ls, chmod, du, etc. He wants to have his own domain and server on the web and I have enough Static IP's, so why not foster this interest. I have an old ultra sparc 5. Are there any CentOS versions that support Sparc? Or recommendations? I know OpenBSD does, but I am more versed in Solaris and versions

I want to set up a cluster that is used for web hosting (RHCS cluster). Recently, I experimented with a 2 node cluster and was able to run it successfully. However, I have started facing some issues with Apache, which I had configured as a service using the Cluster configuration tool. To do this Apache needs a floating IP address. This address is in addition to the network interface IP address.

OK, first time configuring vncserver on Centos7. I have read through a bunch of old messages here on vncserver and thought I had it. Obviously not. 1) cp /usr/lib/systemd/system/vncserver at .service /etc/systemd/system/vncserver at .service 2) vi /etc/systemd/system/vncserver at .service I changed <USER> in both places to root 3) systemctl daemon-reload 4) systemctl

I have had great luck with nvidia fakeraid on RAID1, but I see there are preferences for software raid. I have very little hands on with full Linux software RAID and that was about 14 years ago.

Howdy, I tend to try out many open source apps/packages - games, editors to media tools. I have a bad habit of downloading and extracting source in the /var/tmp directory and then doing configure-make-install process. I am not sure of best practice (good practices) to be followed when installing any software. For example how and where to keep the src. Any comments and/or resources would be really
