Message: [QUOTE="dusty, post: 4576515"] Sorry I took so long to reply. Forgot about this thread. I am using straight rsync. Running an rsync daemon on the servers I want. Then I setup modules for the access. The reason I do this is to avoid having ssh keys with blank passwords on my servers. Also, this is only available on the internal network, so I'll also use things like firewall rules and access-list in rsync to make sure only the machines I want to get rsync access can. Here's an example of a class that calls rsync to get a file listing in a module. ---- require 'rubygems' require 'open4' class RsyncUtils attr_reader :rsync def initialize(path='') paths = ['/bin', '/usr/bin', '/usr/local/bin', '/opt/local/bin' ] paths << path unless path.empty? paths.each() do |path| if(test(?x, "#{path}/rsync")) @rsync = "#{path}/rsync" end end raise "Cannot find rsync, please specify the path" unless @rsync end def list(hostname,path,recurs=false) recursive = "--recursive" if recurs r = run_command("#{@rsync} #{recursive} #{hostname}::#{path}") if r.exitstatus == 0 r.results = RsyncFile.parse_list(r.stdout) end r end def list_recursive(hostname,path) list(hostname,path,true) end private def run_command(command) pid, stdin, stdout, stderr = Open4.popen4(command) ignored, status = Process::waitpid2 pid RsyncResult.new(stdout.readlines, stderr.readlines, status.exitstatus) end end Here is a class that hands back my results ---------- class RsyncResult attr_reader :stdout, :stderr, :exitstatus attr_accessor :results def initialize(stdout,stderr,exitstatus) @stdout = stdout @stderr = stderr @exitstatus = exitstatus end end Here is the class that parses the filelisting to tell me about the files ------ class RsyncFile attr_reader :name, :type, :time, :size FILE_TYPE = 0 DIRECTORY_TYPE = 1 UNKNOWN_TYPE = 2 def initialize(name,type,time,size) @name = name [USER=23513]@time[/USER] = time @size = size @type = type end def is_file? @type == FILE_TYPE end def is_dir? @type == DIRECTORY_TYPE end def self.parse_list(files) results = [] files.each do |file| parts = file.split case parts[0] when /^[rwx-]{10}$/ type = FILE_TYPE when /^d[rwx-]{9}$/ type = DIRECTORY_TYPE else type = UNKNOWN_TYPE end time = Time.local(*ParseDate::parsedate("#{parts[2]} #{parts[3]}")) size = parts[1].to_i name = parts[4] results << RsyncFile.new(name,type,time,size) end results end end Here is how I'd use it in a script. rsync = RsyncUtils.new check = rsync.list(@options["--hostname"],@options["-- path"],@options["--recursive"]) if check.exitstatus > 0 raise "#{check.stderr}" end #This would list all the files - the rsync output if @options["--verbose"] puts check.stdout exit(0) end Now assume I have another class that is do a comparison of the results for me. That is where I'm calling crit.compare. That's not as important, as you can see I'm simply iterating through the results and checking the Time on the current server vs. the time on the remove file. check.results.each do |r| if r.type == RsyncFile::FILE_TYPE diff = ((Time.now - r.time) - @options["--drift"].to_i).to_i critical_files << r.name unless crit.compare(diff) warning_files << r.name unless warn.compare(diff) end end So, basically I would call the script ../rsync_file_age.rb --hostname somehost --path somedir/anotherdir/ -- warning 0:10 --critical 10:20 That would compile a command to RsyncUtils such as rsync somehost::somedir/anotherdir/ It would then use open4 to run that command and would parse the results. Hope that is helpful. BTW an rsyncd.conf file might look like this and would provide the somedir module. pid file = /var/run/rsyncd.pid hosts allow = 10.0.0.10 uid = nobody gid = nogroup use chroot = no max connections = 4 syslog facility = local5 [somedir] path = /var/somedir read only = true [/QUOTE]
