[Pdns-users] pdns-recursor Permissions Error

[Sharone]

The issue is that I need to be able to poll data from the recursive DNS
server, however I have been having trouble with permissions. This is the
error I get when I run snmpwalk from the server.


*# snmpwalk -v2c -c public localhost
.1.3.6.1.4.1.8072.1.3.2.4.1.2iso.3.6.1.4.1.8072.1.3.2.4.1.2.8.112.100.110.115.45.114.101.99.1
= STRING: "Fatal: Unable to generate local temporary file in directory
'/var/run/pdns-recursor': Permission denied"*

Below is what I get when I run the command rec_control as user pdns


*# su -c "rec_control version" -s /bin/sh
pdns4.3.0-beta1.52.master.ga9d432dc0*

Starting the recursor service

Hope this is clearer now
