/bin/cat: Permission denied

Mon Jun 26 22:43:32 UTC 2006

Hello.

I suddenly cannot run "cat" command as /bin/cat file appears to be without
execute permissions (all other files in /bin directory are with them) and I
get "/bin/cat: Permission denied" error.

I had a misfortune to "chmod 555 /bin/cat", then my machine panicked (when
trying to run "cat") and was not able to boot until I changed the /bin/cat
permissions back to read-only. Anyway the system running again but I cannot
install almost any port that uses cat in ./configure script.

I am running FreeBSD 5.4-RELEASE-p16 on Intel(R) Pentium(R) 4 CPU 3.00GHz
(2992.52-MHz 686-class CPU), with two 200GB SATA disks and RAID1 geom
mirror.

Output of dmesg is attached as file.

Question#1: How can I get rid of this problem and repair my cat file to be
able to install new ports again?

Question#2: Why did this happen? I mean everything worked fine for a year or
more until I decided to use hylafax on my machine and found that it cannot
do documet conversion.

Thank you.

Viktoras
