Possible Duplicate: vim re-edit as root I could have sworn I saw this question asked. But after looking though every search result for “vi” I’m stumped/lazy.

Asked by MathewC I think you want something like this: :w !sudo tee “%” I first saw it on commandlinefu. The quotes are only necessary if the file [...]

I would like to use my own outbound email server Haraka with Node.js and Google Apps for inbound mail. Now my domain registrar gives one click Google Apps setup, however I’ve already set up my own outbound server and it says: Caution: The main domain name (www.)mydomain.com is using MX : mail.mydomain.com already. If you want to add Google Apps, you need create a subdomain, e.g. xyz.mydomain.com or remove MX : mail.mydomain.com. So how can [...]

I have a constantly running script that I output to a log file: script.sh >> /var/log/logfile I’d like to add a timestamp before each line that is appended to the log. Like: Sat Sep 10 21:33:06 UTC 2011 The server has booted up. Hmmph. Is there any jujitsu I can use? Asked by Antonius Bloch You can pipe the script’s output through a loop that prefixes the current date and time: ./script.sh | while IFS= [...]

Their main spiel seems to be bonding across different media. It’s something that I’d really like to use for a couple [...]

I have an saslauthd setup to authenticate against PAM. It seems to do its stuff: root@sasltest:~# testsaslauthd -u quest -p #### -s smtp 0: OK “Success.” I have libsasl 2.1.23, postfix 2.7.1.

I need to change the DNSs of my domain, and I’m getting an error that the DNSs aren’t registered. Maybe they simply haven’t propogated yet, but it ocurred to me that what I’m doing seems kind of recursive. If my domain is example.com and my DNSs are ns1.example.com and ns2.example.com, is there a problem with doing that? It seems like I’m trying to point the domain to itself. And in case you’re wondering, I didn’t [...]

I have a module named drbd which I need to use in another module named hacluster. Initially I thought to segregate drbd’s stuff in its own class like this: modules/drbd/[stuff] # this is the DRBD module modules/hacluster/manifests/init.pp # class hacluster { include hacluster::drbd } modules/hacluster/manifests/drbd.pp # class hacluster::drbd The hacluster::drbd class installs and configures DRBD like this: class hacluster::drbd { class { ‘drbd’: service_ensure => undef, service_enable => false, } class { ‘drbd::global_common’: …more stuff… [...]

Here’s the background to my question: A number of people deploy changes to our ASP.NET website … designers deploy HTML and CSS changes, .NET developers deploy ASPX, DLL files, graphic designers deploy images, etc etc. In theory all these deployments are done in a very controlled way – source code is maintained in SVN, deployment packages are created and version controlled, deployments are tested first on a pre-production site, deployments to live are documented. In [...]
