Updating Licenses on Remote Iguana Servers

I work for a vendor that bundles Iguana on our servers and I’ve been working to automate Upgrading Iguana. Upgrading the application is straightforward enough (stage new files, stop service, deploy files, start service) but updating the licenses has been a manual process so I set out to automate the chore.

I am able to update all of our servers using this Lua script because we are using a site to site VPN connection so I have http access to our Iguana instances. I have them all registered in Iguana’s Remote server list and I have synchronized credentials across them. If these conditions cannot be met this script will fail.

The license file is a CSV formatted simply as ServerID,License. It was obtained from the Interfaceware website after I opened each customer and refreshing the maintenance expiration date. I then downloaded, by clicking ‘Save to CSV’ and manually removed the columns we don’t need.

require("stringutil")
require("node")

serverList = {}
user       = 'admin'
password   = 'password'
licensefile = 'D:/activations.csv'

function main() 
   getServerIPs()
   getRemoteIDs()
   parseLicenseFile()
   updateLicenses()
end

function getServerIPs ()
   local f =    io.open('IguanaConfiguration.xml','r')
   local iguanaConfig = f:read('*a') 
   f:close()
   local parsedConfig = xml.parse{data=iguanaConfig}
   local remoteList = parsedConfig.iguana_config.remote_iguana_list   
   for i=1, remoteList:childCount() do
      local s = remoteList:child('remote_iguana',i)
      serverList[i]={ip=s.host}
   end    
   return 'Remote Server IPs read from IguanaConfiguration.xml'
end

function getRemoteIDs()
   for i=1, #serverList do 
      local s=serverList[i].ip
      local serverInfo=net.http.get{url='http://'..s..':6543/monitor_query?',
         auth={username=user,password=password}, 
         timeout=60, 
         live=true}
      local x=xml.parse{data=serverInfo}
      serverList[i]={ip=serverList[i].ip, id=x.IguanaStatus.IguanaId}
   end
   return 'Retrieved Server IDs from Remote Server List'
end

function parseLicenseFile()
   local f = io.open(licensefile)
   local r = f:read('*a')
   f:close()
   
   local t=r:split('\n')
   local x ={}
   for i=1,#t do 
      local s = t[i]:split(',')
      x[s[1]] = s[2]
   end
   
   for i=1, #serverList do 
      local l = x[serverList[i].id:S()]
      trace(l)
      serverList[i]={ip=serverList[i].ip, id=serverList[i].id, lisc=l}
   end
   trace(serverList)
   return 'Server Licenses Mapped to IPs'
end

function updateLicenses() 
   for i=1, #serverList do 
      local u = 'http://'..serverList[i].ip:S()..':6543/submit_license_settings.html?NewLicenseHex='..serverList[i].lisc
      trace(u)
      local updatelisc = net.http.get{url=u,
         auth={username=user,password=password},
         timeout=60,
         live=true}
   end
   return 'Server Licenses Applied'
end

Upon further review this isn’t actually working, the update settings page requires javascript. I was tricked because the first chunk of my license were already updated. I’m going to post this in the questions forum.
