Folks,
I am trying to get listen to be viewable by other users than root. I have
checked the permissions on listen and all appears OK, but when I
try to run it as a common user, I get a failure.
Here is the error message:
[EMAIL PROTECTED]:~$ listen
socket: Operation not permitted
[EMAIL PROTECTED]:~$
If I do a strace here is what I get
All above the top of the capture appears the same as the strace under
root:
read(3, "", 4096) = 0
close(3) = 0
munmap(0x40018000, 4096) = 0
close(4) = 0
socket(PF_PACKET, SOCK_PACKET, 512) = -1 EPERM (Operation not permitted)
dup(2) = 3
fcntl64(3, F_GETFL) = 0x8002 (flags O_RDWR|O_LARGEFILE)
fstat64(3, {st_mode=S_IFCHR|0620, st_rdev=makedev(3, 1), ...}) = 0
ioctl(3, SNDCTL_TMR_TIMEBASE, {B38400 opost isig icanon echo ...}) = 0
old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS,
-1, 0) = 0x40018000
_llseek(3, 0, 0xbffff580, SEEK_CUR) = -1 ESPIPE (Illegal seek)
write(3, "socket: Operation not permitted\n", 32socket: Operation not permitted
) = 32
close(3) = 0
munmap(0x40018000, 4096) = 0
exit_group(1) = ?
[EMAIL PROTECTED]:~$
The problem appears to be with the socket part, but am not sure how to
deal with it.
