[syslog-ng]syslog-ng blanks in Servicename

[Lixin Liu]

Is it possible to DNS to verify the valid hostnames? Our syslog produces ma=
ny
bogus hostnames and it is almost impossible to list all of them in bad_host=
name().

Thanks,

Lixin.

options { bad_hostname("\t"); };

here's the set of special characters you can use (quoting cfg-lex.l):

<string>\\a                { append_char(7); }
<string>\\n                { append_char(10); }
<string>\\r                { append_char(13); }
<string>\\t                { append_char(9); }
<string>\\v                { append_char(11); }

e.g \a, \n, \r, \t and \v are all supported special characters (similarly t=
o
C)
