 |
|
Every few days something rewrites /dev/null so that it becomes a standard file,
permissions 644, and not a character device, permissions 666. I can't find out
which program is doing this - has anyone else seen the problem?
Thanks - Will |

Hi cwr,
as far as i know, /dev/null should be something like 0666.
I don't know which program made that changes, but I have few ideas :
- a) a recent udev update
- b) a weird syslog-ng rule
For b), it happened few years ago; I added this rule to my /etc/syslog-ng/syslog-ng.conf :
| Code: | destination myrule { file("/dev/null"); };
filter f_myrule { program("application.*"); };
log { source(src); filter(f_myrule); destination(myrule); flags(final); }; |
And every time that I restarted my syslog-ng : it changed the chmod 
Good luck :]
