Thank You.
I will look in there. I am curious, where does the +128 come from.
I was receiving an error message, but I understood it was a print issue within
the GUI and not an actual character limitation "**ERROR** Buffer too short @
httpd.c:1431"
It looks as though I may be wrong. I also am not a programmer, so any help
would be greatly appreciated. It looks like the globals-defines.h defines the
LEN_GENERAL_WORK_BUFFER, would this be where I make the change? The 1024 of the
General Work Buffer seems to fit.
M
#define LEN_TIMEFORMAT_BUFFER 48
#define LEN_CMDLINE_BUFFER 4096
#define LEN_FGETS_BUFFER 512
#define LEN_HUGE_WORK_BUFFER 4096
define LEN_GENERAL_WORK_BUFFER 4096
#define LEN_GENERAL_WORK_BUFFER 1024
#define LEN_MEDIUM_WORK_BUFFER 128
#define LEN_SMALL_WORK_BUFFER 24 /* nnn.nnn.nnn.nnn\n */
#define LEN_ADDRESS_BUFFER
sizeof("FEDC:BA98:7654:3210:FEDC:BA98:7654:3210")+4

My current BPF filter is 1,151 characters with no spaces and 1037 characters

Sounds like the limit is 1024 + 128 = 1152. Do you get any errors in the log
when your BPF is too large?
I'm no C or Ntop codebase expert, but I think the bit of the code that is of
interest is in util.c around line 1532.
