Re: syslog-ng failed, cannot open a connection to UNIX[/dev/log]

[Aleksandrov Artyom]

Hello,

I found the problem. Monit can`t open the socket because it try
another type (sock_steam instead of sock_dgram).

socket(PF_FILE, SOCK_STREAM, 0)         = 4
fcntl(4, F_GETFL)                       = 0x2 (flags O_RDWR)
fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK)    = 0
connect(4, {sa_family=AF_FILE, path="/dev/log"}, 110) = -1 EPROTOTYPE
(Protocol wrong type for socket)
shutdown(4, 2 /* send and receive */)   = 0
close(4)                                = 0
write(2, "'syslog-ng' failed, cannot open "..., 63'syslog-ng' failed,
cannot open a connection to UNIX[/dev/log]

Also there`s bug about this problem (2006 year).
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=384802

I think it will be right if Monit can try open socket both types.

What do you think about it?

Best regards, Artyom
