#28 Bug in c snmp plugin: Handling of histfile length

[Sascha Ittner]

There is a bug in the handling of maximum rows of the counter history files. There are two problems:

1. there is no constraint which limit the maximum number of lines that are read. This could lead to overwritten variables and buffer overflows.

2. the file_read function calculates the starting line correctly, but doesn't use the calculated value.

Please find attached by suggested fix.

Kind Regards

Sascha
