Bug #920
closedSuricata failed to parse address
Description
I want to check subnet but exclude one ip .
I've read a documentation at https://redmine.openinfosecfoundatio...Suricata_Rules and report this example :
[10.0.0.0/24, !10.0.0.5] (10.0.0.0/24 except for 10.0.0.5)
Now, in my suricata configuration I've set HOME_NET wit :
HOME_NET: "[10.10.10.0/24, !10.10.10.247]"
But, when I start suricata receive this error :
12/8/2013 -- 08:56:09 - <Error> - [ERRCODE: SC_ERR_ADDRESS_ENGINE_GENERIC(89)] - failed to parse address " 10.10.10.247"
12/8/2013 -- 08:56:09 - <Error> - [ERRCODE: SC_ERR_INVALID_YAML_CONF_ENTRY(139)] - failed to parse address var "HOME_NET" with value "[10.10.10.0/24, !10.10.10.247]". Please check it's syntax
12/8/2013 -- 08:56:09 - <Error> - [ERRCODE: SC_ERR_INVALID_YAML_CONF_ENTRY(139)] - basic address vars test failed. Please check /etc/suricata/suricata.yaml for errors
I've Suricata version 1.4.5 RELEASE and same problem with Suricata version 2.0dev (rev ff668c2).
How can I exclude one ip from check, what is correct syntax .
Thanks

Can you check:
"[10.10.10.0/24, !10.10.10.247/32]"
?
thanks

With Suricata v1.4.5 it works fine .
It's a git version problem ?

Anoop, can you check this? Also, if it's a still an issue, a new patch should have some tests.

Does it matter if you leave or not a space between the nets?
Updated by Jesson Kang over 11 years ago
I have the same problem as Paolo Dangeli .
[root@wcc-pt-seccheck01 suricata]# suricata -V
This is Suricata version 2.0beta1 RELEASE
Updated by Jesson Kang over 11 years ago
I have tested the patch in [[https://github.com/inliniac/suricata/pull/508]]
Suricata report a error that like this " error parsing signature "alert http $HOME_NET any -> $EXTERNAL_NET any" all the same.
I think this is not only because space ,also because in parsing "!".
