Cisco recommends dual DNS: public (external) and local (internal) DNS in order that Mobile and Remote Access can work more efficiently. Pinpoint entries (a zone created for a single host only) as suggested by Cisco could be a solution, but our DNS server is authoritative for the parent domain, so this wouldn't work. With the follwing setup and by using RPZ, jabber requests coming from the internet, are forwarded to Expressway-Edge and requests coming from the internal network are forwarded to Expressway-Core. Public (External) Records needed : _collab-edge._tls.example.com      SRV 10 10 8443 expe1.example.com. Local (Internal) Records needed: _cisco-uds._tcp.example.com        SRV    10 10 8443 cucm1.example.com _cuplogin._tcp.example.com         SRV    10 10 8443 cup1.example.com Cisco states that a client first searches for internal DNS records: For example, Adam McKenzie's services domain is example.com when he starts the client. The client then issues the following query:

You can still use Adobe Flash as of January 2021 by "whitelisting" certain sites. I mostly use it to manage some old Enterprise Appliances. All you have to do is edit your mms.cfg file, located in:   C:\Windows\System32\Macromed\Flash   or C:\Windows\SysWOW64\Macromed\Flash So, the file should look be edited as following: EOLUninstallDisable=1 AutoUpdateDisable=1 EnableAllowList=1 AllowListRootMovieOnly=1 AllowListURLPattern=*://mydomain.example.com According to the Adobe Flash Admin guide, AllowListUrlPattern syntax is the follwing: AllowListUrlPattern = <scheme> ://<host>:<port>/<path> <scheme> = ‘*’ | ‘http’ | ‘https’ <host> = <any char except ‘.’ and ‘*’> <port> (optional) = <any valid port number> <path> = ‘/’ <any chars>   With EnableAllowList=1 set, administrators can then specify a discrete URL or pattern to allow

Before shutting down your system, copy the output of your current fstab in order to mount your partitions: # cat /etc/fstab Boot from a live cd (I used an ubuntu 14.04) You 've got to mount somewhere the original filesystem in order to copy it, preferably as read-only: Assuming our old disk is /dev/sda with 3 partitions (all of them LVM): # mkdir /mnt/olddisk /mnt/olddisk/oldboot /mnt/olddisk/oldroot /mnt/olddisk/oldvar # mount -o ro /dev/mapper/vg1-lv_XXX /mnt/olddisk/oldboot # mount -o ro /dev/mapper/vg1-lv_XXY /mnt/olddisk/oldroot # mount -o ro /dev/mapper/vg1-lv_XXZ /mnt/olddisk/oldvar Your old fstab should look like this # cat /mnt/olddisk/oldroot/etc/fstab / dev / mapper / vg1-lv_XXX / ext3 defaults 1 1 / dev / mapper / vg1-lv_XXY / boot ext3 defaults 1 2 / dev / mapper / vg1-lv_XXZ / var ext3 defaults 1 2 tmpfs / dev / shm

In my previous post I explained how to run a custom script triggered by an IFTTT reipe. In this post I will explain how to get a SIP call when an IFTTT action is triggered. I assume you have created the recipe, linked Dropbox and configured incrontab as explained here . Requirements: -A cli SIP client, pjsua (from the pjsip library) is perfect for this job -expect package (in order to "talk" to pjsua with spawn) -festival package (this includes text2wave for text-to-speech) I didn't find pjsip as a package for Debian, so I had to download it from  http://www.pjsip.org and compile it manually, it's straightforward (configure-make dep-make). pjsua is located inside the /pjsip-apps folder so you may either copy it somewhere convenient or create a soflink in order to run it. Create your pjsip conf file (this may depend on your SIP provider) and paste: --null-audio --registrar sip:your.sip.provider.com --realm=* --id sip:sipuser@your.sip.provider.com --us

Requirements: -an IFTTT account -a Dropbpx account linked to your IFTTT account -a server running linux (mine runs Debian linux). - incrontab package, available on most linux distros. First of all, install Dropbox on your linux box. You may find instructions here: https://www.dropbox.com/install?os=lnx Run Dropbox and create a folder named IFTTT on your home Dropbox folder. mkdir ~/Dropbox/IFTTT Then, you have to create your IFTTT recipe at ifttt.com. You may use whatever "this" statement you wish. On "that" statement you chose Dropbox, and create a file. Give a name to your file, for my example I use "runme". In the content you may put whatever you want. In Dropbox folder path you use IFTTT. Create your script file on your home folder named "script.sh" and make it executable: chmod  +x script.sh. Make sure your script executes properly: ./script.sh Add the user that has both rights to run the script and to write into the Drop
