Can anyone describe a way in FS to get rid of crawlers and hackers testing your PBX second by second on the internet?! What is the problem? This is ls of my FS's sqlite db after some annoying behaviours of hackers and crawlers violently done: [root@freeswitch db]# ll total 705580 -rw-r--r-- 1 root root 7168 Sep 29 13:20 callcenter.db -rw-r--r-- 1 root root 14336 Sep 23 10:29 call_limit.db -rw-r--r-- 1 root root 257024 Sep 29 13:56 core.db -rw-r--r-- 1 root root 5120 Sep 29 13:20 fifo.db -rw-r--r-- 1 root root 98304 Sep 24 11:34 sofia_reg_sipinterface_2.db -rw-r--r-- 1 root root 367616 Sep 25 18:31 sofia_reg_sipinterface_3.db -rw-r--r-- 1 root root 500726784 Sep 29 13:56 sofia_reg_sipinterface_5.db -rw-r--r-- 1 root root 221003312 Sep 29 13:56 sofia_reg_sipinterface_5.db-journal -rw-r--r-- 1 root root 16384 Sep 23 10:29 voicemail_default.db [root@freeswitch db]# sofia_reg_sipinterface_5.db belongs to the interface listening on 5060 port. As you see sofia_reg_sipinterface_5.db exceed 500MB of size! and this db has crashed! and leads to drop port 5060 of interfaces. when i ask fs_cli about profiles it tells me: +OK log level [7] freeswitch@internal> sofia status Name Type Data State ================================================================================================= sipinterface_3 profile sip:mod_sofia@192.168.2.73:5080 RUNNING (0) voicemail_1 alias sipinterface_2 ALIASED voicemail_2 alias sipinterface_2 ALIASED sipinterface_2 profile sip:mod_sofia@192.168.2.73:5070 RUNNING (0) ================================================================================================= 2 profiles 2 aliases Which open source firewalls can handle automatically weird sip requests to ban?! Sincerely yours,

[Freeswitch-dev] any pre-existing routine to escape a string for any control characters/etc?
by Nathan Neulinger 01 Oct '13

01 Oct '13

The switch_escape_string seems to have a hardwired list and doesn't cover other non-printables like ^G or similar. Is there anything already existing that would cover "all non-printables"? If not, I'll put one together. (Looking for something to use in logging functions to avoid sending garbage to display.) -- Nathan ------------------------------------------------------------ Nathan Neulinger nneul(a)mst.edu Missouri S&T Information Technology (573) 612-1412 System Administrator - Architect
