i can't make link with the command 'ln'
 

when i make a symbolic link of libdha.so.0.1,but shell says it's not an allowable operation
[root@zd libdha]# ln -sf libdha.so.0.1 libdha.so.0

the file libdha.so.0.1 exits in the directory,the information is as follow:
-rwxrwxrwx 1 root root 286656 5? 14 13:49 libdha.so.0.1

what's the matter?

More info needed. I doubt the shell says "not an allowable operation". I've never seen it. I could be wrong. So, we need more info. What's exact error? What exactly does "ls -l libdha.so.0.1" output? What's the "5?" doing in the ls -l output? What shell? Which distribution?

i'm sorry.
i made a mistake.
the language of my operation system is Chinese,so i must translate the error into English.
and '286656 5?' in the information of libdha.so.0.1 is the date of libdha.so.0.1

Hi,

You still haven't given me the info I asked for. Alongwith that, give me the output of the command "lsattr" on the file, ie:

lsattr libdha.so.0.1

Arvind

[zd@zd libdha]$ lsattr libdha.so.0.1
lsattr: Inappropriate ioctl for device While reading flags on libdha.so.0.1

i know now why i can't make a symbol link.The file which i want link is in fat32 partition
thank you
