Description of problem: It seems that this happens when munin runs. SELinux is preventing /usr/bin/perl from using the 'signal' accesses on a process. ***** Plugin catchall (100. confidence) suggests *************************** If sie denken, dass es perl standardmäßig erlaubt sein sollte, signal Zugriff auf ping_t Prozesse zu erhalten. Then sie sollten dies als Fehler melden. Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen. Do zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen: # grep /usr/sbin/munin /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:munin_t:s0 Target Context system_u:system_r:ping_t:s0 Target Objects [ process ] Source /usr/sbin/munin Source Path /usr/bin/perl Port <Unbekannt> Host (removed) Source RPM Packages perl-5.14.3-218.fc17.x86_64 Target RPM Packages Policy RPM selinux-policy-3.10.0-161.fc17.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.6.9-2.fc17.x86_64 #1 SMP Tue Dec 4 13:26:04 UTC 2012 x86_64 x86_64 Alert Count 83 First Seen 2012-12-13 11:05:57 CET Last Seen 2012-12-13 22:20:57 CET Local ID 9b07c65b-a9b0-4cfa-a2bc-09c5fcaa46c4 Raw Audit Messages type=AVC msg=audit(1355433657.317:6325): avc: denied { signal } for pid=28742 comm="/usr/sbin/munin" scontext=system_u:system_r:munin_t:s0 tcontext=system_u:system_r:ping_t:s0 tclass=process type=SYSCALL msg=audit(1355433657.317:6325): arch=x86_64 syscall=kill success=yes exit=0 a0=ffff8cda a1=1 a2=7fc387948440 a3=7fff8c280ce0 items=0 ppid=7908 pid=28742 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=/usr/sbin/munin exe=/usr/bin/perl subj=system_u:system_r:munin_t:s0 key=(null) Hash: /usr/sbin/munin,munin_t,ping_t,process,signal audit2allow #============= munin_t ============== allow munin_t ping_t:process signal; audit2allow -R #============= munin_t ============== allow munin_t ping_t:process signal; Additional info: hashmarkername: setroubleshoot kernel: 3.6.9-2.fc17.x86_64 type: libreport
