howdy,

two questions about snort 2.9.0 on sparc.


one on daq and another on an odd behavior of http_inspect and ftp_telnet
configuration..

the first,  about daq 0.2 compilation  was about some errors like the
following (see email thread below for complete list).



In file included from sf_gencode.c:87:
sll.h:86: error: syntax error before "u_int16_t"
sll.h:86: warning: no semicolon at end of struct or union
sll.h:87: warning: type defaults to `int' in declaration of `sll_hatype'
sll.h:87: error: ISO C forbids data definition with no type or storage
class


Was finally able to compile by removing the following lines in sfbpf/sll.h

$ diff sll.h sll.h.orig
82,83c82,93
< #define SLL_HDR_LEN 16          /* total header length */
< #define SLL_ADDRLEN 8           /* length of address field */
---
#define SLL_HDR_LEN    16          /* total header length */
#define SLL_ADDRLEN    8           /* length of address field */

struct sll_header
{
    u_int16_t sll_pkttype;      /* packet type */
    u_int16_t sll_hatype;       /* link-layer address type */
    u_int16_t sll_halen;        /* link-layer address length */
    u_int8_t sll_addr[SLL_ADDRLEN]; /* link-layer address */
    u_int16_t sll_protocol;     /* protocol */
};


Thanks for reporting this.  We'll look into it.


2nd question.  Are the http_inspect and ftp_telnet preprocesors related in
any way?    It seems that the configuration parsing may be mixing them up?
(or it may just be my configuration?).


No - at least the shouldn't be.  It sounds like maybe you have an old ftp so
registering as http?  Definitely weird.  Did you uninstall the old dynamic
preprocessors first?  Have you tried changing the order of preprocessor
configs in your conf (http, ftp and then ftp, http)?


When I enable ftp_telnet global, with the following on the conf file:

       preprocessor ftp_telnet: global inspection_type stateful
check_encrypted encrypted_traffic no


 I get the following error:

ERROR: snort.conf(236) => Stateful HttpInspect processing is not yet
available.  Please use stateless processing for now.
Fatal Error, Quitting..


why would the ftp_telnet configuration error with  'HttpInspect' .

if I set the ftp_telnet inspection to stateless, I get the following error:

ERROR: snort.conf(238) => Global configuration must contain an IIS Unicode
Map configuration.  Use token 'iis_unicode_map'.
Fatal Error, Quitting..



Once again this error seems to be from http_inspect (as that directive is
set in that preproc)

If I completely remove (comment out) all ftp_telnet lines (global, server
and protocol), then snort starts up fine..


am I missing something here?

The DAQ developers *are* on this list, however, the best bet for these

Thanks.

howdy:

does anyone know if the 2.9.0 snort can be compiled in Solaris (sparc?).

I'm currently stuck trying to compile the daq 0.2.  it errors at the
following:

any help would be appreciated.
