Sea= rching in SINGLE files or in a directory which contains only *.sh-files is ok= ): ... 07:42:32 kernel: mc[17515]: segfault at a39349a0 ip a2fbdf81 sp b0f41af4 err= or 4 in libpcre.so.1.2.9[a2f94000+44000] 07:42:32 kernel: grsec: From 192.168.100.1: Segmentation fault occurred at a= 39349a0 in /usr/bin/m c[mc:17515] uid/euid:0/0 gid/egid:0/0, parent /bin/bash= [bash:16795] uid/euid:0/0 gid/egid:0/0 07:42:32 kernel: grsec: From 192.168.100.1: denied resource overstep by requ= esting 4096 for RLIMIT_CORE against limit 0 for /usr/bin/mc[mc:17515] uid/eui= d:0/0 gid/egid:0/0, parent /bin/bash[bash:16795] uid/euid:0/0 gid/egid:0/0 ... The same happens on a fresh test installation. Right now I'm thinking about using 'paxctl' on '/usr/bin/mc', but I'm not re= ally sure...: 1. If this would be a solution 2. Which options to use - and 3. On which parts ('/usr/bin/mc'?) exactly. I'm testing with: ... paxctl -cm /usr/bin/mc ... But had no luck until now. Anybody got a hint or experiencing the same?
