After this you can run su.

sudo passwd root

This is where the bash variable handling makes it even more interesting. Instead of just doing something like "mv $var", we can replace text in the filename using this syntax:

${var/originaltext/replacetext}

So now, if we run this command on our directory:

for f in *;do mv $f ${f/test/prod};done

I would like to know how to create a parsing using the class HTTP Connection, I have to get the data from / ip-do-server/cgi-bin/mailgraph.cgi and switch to
Another page in PHP.


// description of your code here

// insert code here..

// it's simple to add one key but this helps when i'm on a machine w/ multiple authorized hosts
// use like `ssh-copy-id ww1.example.com` -- make sure you have `ssh-agent` running and have added keys w/ `ssh-add` (use `ssh-add -L` to check)
// got this from the OpenSSH in Ubuntu, don't have it on mac afaik?

#!/bin/sh

# Obviously, the remote machine must accept password authentication,
# or one of the other keys in your ssh-agent, for this to work.

Now try logging into the machine, with "ssh '$1'", and check in:

Fix errors like
svn: Your .svn/text-base directory may be missing or corrupt; run 'svn cleanup' and try again
svn: Can't open file 'blabla/.svn/text-base/entries': No such file or directory

require 'pathname'

def recurse(dir)
  for child in dir.children
    next unless child.directory?              # ignore files
    next if child.basename.to_s == '.svn'     # ignore .svn directory
    next unless (child + '.svn').exist?       # ignore unadded directories
    text_base_dir = child + '.svn/text-base'  # path to text-base dir
    next if text_base_dir.exist?              # ignore existing text-base dirs
    text_base_dir.mkdir
    puts text_base_dir
    recurse child
  end
end

recurse Pathname.new('.')

dump the repository to a text file

svnadmin dump repositoryPath > repository.dumpfile

create the new repository on the new machine

cd /path/to/new-repository-parent-directory
svnadmin create repository-name
svnadmin load repository-name < repository.dumpfile

transfer your local svn project to the new machine. Use absolute paths!

svn switch --relocate oldurl newurl

Example:

svn switch --relocate http://myoldcrapserver.com/svn/myfunkyproj svn+ssh://mykickingnewserver.com/var/svn/myfunkyproj

To connect Tomcat to lighttpd use the following code:

server.modules  += ( "mod_proxy_backend_ajp13" )
$HTTP["url"] =~ "^/tomcat/" {
  proxy-core.balancer = "round-robin"
  proxy-core.protocol = "ajp13"
  proxy-core.backends = ( "localhost:8009" )
  proxy-core.max-pool-size = 16
