Hi Guys,

I am new to the Suricata world, and I'm trying to validate that it can deal with very large HOME_NET specifications. I am starting with Suricata version 1.2.1 running on a Ubuntu Linux Lucid OS. 

I have a customer that has between 240 and 260 HOME_NET entries. I tried entering, 248 entries in suricata.yaml, and I get strange results.

I get: "Failed to parse configuration file at line 773: did not find expected key". Line 773 is a blank line and precedes the line with EXTERNAL_NET: "!HOME_NET".

I have tried commenting out EXTERNAL_NET and all the "_SERVERS entries (i.e. HTTP_SERVERS etc), but then all rules that specify EXTERNAL_NET are dropped. I also tried EXTERNEL_NET: "any" but that gets the same line 773 failure as mentioned above..

If I leave HTTP_SERVERS: in, I get the "Failed to parse configuration file at line 775: did not find expected key" message. Again, line 775 is a blank line and precedes the line with HTTP_SERVERS:

I would be glad to furnish any additional information you may need or try anything that you suggest.

Thanks in advance, and I hope to hear from you soon.
