Fix for 'unknown ACL condition/modifier in "spam = debian-spamd:true"'

Exim configuration error in line 438 of /var/lib/exim4/config.autogenerated.tmp: error in ACL: unknown ACL condition/modifier in "spam = debian-spamd:true" root@sh1:/etc/exim4# dpkg-reconfigure exim4-config 2015-10-25 14:09:40 Exim configuration error in line 438 of /var/lib/exim4/config.autogenerated.tmp: error in ACL: unknown ACL condition/modifier in "spam = debian-spamd:true" Invalid new configfile /var/lib/exim4/config.autogenerated.tmp, not installing /var/lib/exim4/config.autogenerated.tmp to /var/lib/exim4/config.autogenerated The one stumped be for a bit but the solution - at least on a Debian based system - is to ensure you have installed 'exim4-daemon-heavy` instead of the light packages, aptitude install exim4-daemon-heavy.If this has helped comment of follow me .

Linux Benchmarking

Simple Linux Performance ScriptWhen deploying new virtual machines with different provides I like to do basic performance tests using built in utilities like `dd` and `bc`. I had a little script linux-benchmark.sh which I have now cleaned up and making it public. When run it will do basic test for HD, Internet and CPU and save it as a timestamped text file.Sample output: root@sh1:~# ./linux-benchmark.sh Please be patient, this might take a minute or so. Hostname: sh1 IP(s): 45.55.218.113 CPU model: Intel(R) Xeon(R) CPU E5-2630L v2 @ 2.40GHz Number of cores: 1 CPU frequency: 2399.998 MHz System uptime: 60 days, 2:17, Total amount of ram: 500 MB Total amount of swap: 2929 MB Calc PI to 5000: 0m31.818s Download speed: 106MB/s I/O (conv=fdatasync): 528MB/s I/O (oflad=dsync): 293MB/s The `linux-benchmark.sh` script #!/bin/bash # Author: Daniel Sokolowski # source: https://bitbucket.org/snippets/danielsokolowski/G5oeA…

Linphone keys (DTMF) not working with Freeswitch VOIP Server

Work around to key tones not working in Linphone when connected through FreeswtichIf you find that after dialing into any IVR your key presses are not registering, and you are connecting to a Freeswitch voip gateway it is likely due to this Bug: Telephone-event codec clock-rate mismatch (leads to DTMF issue); go 'Options > Settings > Codec' and move the 8000Hz codes up.A temporary work around is to change your codec priorities in Linphone to use one of the lower quality 8000Hz ones first.

dnsmasq as an external DNS server

Creating a 'NS' record It's NOT possible - try setting u BIND instead or contacting the author to add support for it; I am creating this entry so that it would save hours of searching for others.
The basic setup that should work is to point your domain dns servers to to 'ns1.yourdomain.com` where ns1 resolves to your servers IP, however because dnsmasq can not answer with a NS record and the process fails - that is my understanding based on my readings
