Code and config in these examples are tested on a debian box.<\/p>\n
What we need:
\n-A software for speech synthesis
\nespeak is good for this purpse. quiet configurable and the voice quality is OK.<\/p>\n
apt-get install espeak <\/p>\n
-A software that can trigger events, when certain log entries appear
\nswatch is our friend here. it reads logs in realtime and triggers a command if a specific pattern is found.
\nIn our case it will just trigger espeak to say something.<\/p>\n
apt-get install swatch <\/p>\n
Now that we have our tools lets make a sample talker…
\nWe want our box to report, if new (no-spam) mail arrived.<\/p>\n
I’m using spamassassin to filter my mail.
\nI get a line similar to<\/p>\n
Jul 26 16:34:04 star spamd[13365]: spamd: clean message (-2.4\/0.5) for mailbox:1001 in 1.9 seconds, 7128 bytes.
\nin \/var\/log\/mail.log<\/p>\n
everytime a good messages reaches my inbox.<\/p>\n
So create a config file for swatch to look out for lines like that<\/p>\n
File: \/etc\/swatch\/ham<\/p>\n
watchfor \/clean message\/
\nexec “espeak new_mail &”<\/p>\n
The only thing left to do now is to start the swatch daemon<\/p>\n
\/usr\/bin\/swatch –daemon –config-file=\/etc\/swatch\/ham –tail-file=\/var\/log\/mail.log<\/p>\n
I think you got the point. The possibilities are endless. Everything that is logged can be spoken.<\/p>\n
But there are other interesting possibilities. Lets say you want your box to report new available updates to you.
\nThis little script can do it when run from a repeating cron-job:<\/p>\n
#!\/bin\/bash
\napt-get update
\nUPDATELINE=`apt-get –simulate upgrade | grep remove`
\nEINS=`echo $UPDATELINE | cut -d ” ” -f 1`
\nZWEI=`echo $UPDATELINE | cut -d ” ” -f 3`
\nDREI=`echo $UPDATELINE | cut -d ” ” -f 6`
\nVIER=`echo $UPDATELINE | cut -d ” ” -f 10`
\n((UPDATES=EINS+ZWEI+DREI+VIER))
\nif [ $UPDATES -gt 0 ]; then
\nespeak “REPORT: i need $UPDATES updates! please install as soon as possible”
\nfi<\/p>\n
Now you have got all the tools to make your server an absolutely anoying brabbling box.<\/p>\n","protected":false},"excerpt":{"rendered":"
