SELinux is preventing /usr/sbin/pppd from 'write' accesses on the directory ppp. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that pppd should be allowed write access on the ppp directory by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep pppd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:pppd_t:s0 Target Context system_u:object_r:pppd_lock_t:s0 Target Objects ppp [ dir ] Source pppd Source Path /usr/sbin/pppd Port <未知> Host (removed) Source RPM Packages ppp-2.4.5-17.fc15 Target RPM Packages Policy RPM selinux-policy-3.9.16-29.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.38.7-30.fc15.i686 #1 SMP Fri May 27 06:02:17 UTC 2011 i686 i686 Alert Count 1 First Seen 2011年06月12日 星期日 11时18分15秒 Last Seen 2011年06月12日 星期日 11时18分15秒 Local ID 1cda388a-2c6e-417c-b1b5-8f8e7ff5419e Raw Audit Messages type=AVC msg=audit(1307848695.157:108): avc: denied { write } for pid=10297 comm="pppd" name="ppp" dev=tmpfs ino=11860 scontext=system_u:system_r:pppd_t:s0 tcontext=system_u:object_r:pppd_lock_t:s0 tclass=dir type=SYSCALL msg=audit(1307848695.157:108): arch=i386 syscall=open success=no exit=EACCES a0=a9e760 a1=800c2 a2=1a4 a3=a9e760 items=0 ppid=795 pid=10297 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=pppd exe=/usr/sbin/pppd subj=system_u:system_r:pppd_t:s0 key=(null) Hash: pppd,pppd_t,pppd_lock_t,dir,write audit2allow #============= pppd_t ============== #!!!!

I added a label for /var/lock/ppp but I overlooked allow pppd_t pppd_lock_t:file manage_file_perms; Tommy, you can allow it for now using # grep pppd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp A new build will be available tomorrow, Thank you for testing of the ppp package in update-testing repo.
