Both /bin and / have 'drwxr-xr-x' permissions and /bin/zsh has the |
| 14 |
same, of course without 'd'. |

[root@darkness:/usr] # file /bin/zsh |
| 21 |
/bin/zsh: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), stripped |
| 22 |
|
| 23 |
So, it is a normal executable file. |

/lib64/ld-linux-x86-64.so.2 is a symlink to /lib64/ld-2.5.so which can |
| 32 |
be executed, /bin/zsh is /linked/ to the symlink and their permission |
| 33 |
are IMHO correct: |
| 34 |
|
| 35 |
-rwxr-xr-x 1 root root 137226 2007-06-17 16:20 /lib64/ld-2.5.so* |
| 36 |
lrwxrwxrwx 1 root root 9 2007-06-17 16:21 /lib64/ld-linux-x86-64.so.2 -> ld-2.5.so* |

Well, I think it's the right one. See above. |

As stated earlier, there is no noexec flag: |
| 49 |
|
| 50 |
/dev/sda2 on / type ext3 (rw,noatime) |

That's due to the ZSH settings/command. |
| 65 |

PS. |
| 67 |
I really dislike this problem :D |
