Re^2: Why Perl misses installed modules ?

Hi,

thanks for the tip. That solved particular problem...I thought this will help also in other cases, but I still get weird results (although am pretty much sure I'm wrong again)...

I've change chmod a+r on other directories and files too, but still get error on other file:

sudo -u asterisk ./zoip.agi  /usr/share/asterisk/agi-bin/ZORK1.DAT
Can't locate Asterisk/Games/Zork/StoryFile.pm in @INC (@INC contains: 
+/usr/share/asterisk/agi-bin/lib /etc/perl /usr/local/lib/perl/5.8.8 /
+usr/local/share/perl/5.8.8 /usr/lib/perl5 /usr/share/perl5 /usr/lib/p
+erl/5.8 /usr/share/perl/5.8 /usr/local/lib/site_perl .) at ./zoip.agi
+ line 18.
BEGIN failed--compilation aborted at ./zoip.agi line 18.

but I've checked path and file :

It must be my mistake again, but have no clue what I did wrong...

Thanks in advance,

Ah, the mysteries of unix file permissions ;-). Check out the chmod lines in my previous answer. I used a+r for the file, but a+rx for the directories. For a directory the flags r and x have different meaning than for files. The r-flag allows access to files in the directory (if you already know the name). The x-flag allows you to read or search the directory. So except for special cases you normally want both flags either on or off In your case both Games and Zork need another x.	[reply]

You have it backwards. The x-flag allows access to files in the directory, which is why you need it at a minimum. The r-flag allows you to read the directory.	[reply]

I'm sure I'm right with this. This was the way on Solaris and when I use 'man 2 chmod' on linux, I find the following sentence (translated from german): `S_IXOTH 00001 Execute rights for others, on directories: others + are allowed to search directory` [download] I also used this effect a few times to make dirs unreadable, but allowed the files in it to be read (security by obscurity, but better than nothing). UPDATE: Sure I was, but wrong. As wrong as the man page.	[reply] [d/l]
