This in reality is a application id. I just happen to know the password. The application uses this id to ftp files in and out. There are some other FTP jobs too that login using this id.

That just makes me think of the password locking (after x invalid attempts) as a bad practice. If I want to bother you, I would type your password wrongly for x times everyday.
Unless there is a way to identify (atleast the originating ip address) of the machine from which wrong attempt has been made, this see this as a bad practice.
I had this problem with DBA's trying to login as "oracle" and fat-fingering the password several times which locks the account. That by itself is not bad ... but ... then the cron jobs for "oracle" stop running and I get paged. So, to prevent this from happening I added the following line in /etc/user_attr:
This prevents the account from being locked if the password is not entered correctly after a few tries. There are security risks in doing this (brute force password guessing among others) so be careful if you implement this method.
Hello all. I think I have a big problem. the /etc/passwd file got overwritten and now I can't su as root when I telnet into this machine. I am running yp on a different machine and tried to push the passwd file out to all machines, but it didn't help. I noticed that there is a passwd file in... (12 Replies)

I have an K580 HP server.
All I did was change the IP address on the NIC and now I can't telnet into it.

Also, it won't boot if the console monitor is plugged in.
ANY IDEAS??? (1 Reply)

_lwp_mutex_unlock
_lwp_mutex_lock(2) System Calls _lwp_mutex_lock(2)NAME
_lwp_mutex_lock, _lwp_mutex_unlock, _lwp_mutex_trylock - mutual exclusion
SYNOPSIS
#include <sys/lwp.h>
int _lwp_mutex_lock(lwp_mutex_t *mp);
int _lwp_mutex_trylock(lwp_mutex_t *mp);
int _lwp_mutex_unlock(lwp_mutex_t *mp);
DESCRIPTION
These functions serialize the execution of lightweight processes. They are useful for ensuring that only one lightweight process can exe-
cute a critical section of code at any one time (mutual exclusion). LWP mutexes must be initialized to 0 before use.
The _lwp_mutex_lock() function locks the LWP mutex pointed to by mp. If the mutex is already locked, the calling LWP blocks until the mutex
becomes available. When _lwp_mutex_lock() returns, the mutex is locked and the calling LWP is the "owner".
The _lwp_mutex_trylock() function attempts to lock the mutex. If the mutex is already locked it returns with an error. If the mutex is
unlocked, it is locked and _lwp_mutex_trylock() returns.
The _lwp_mutex_unlock() function unlocks a locked mutex. The mutex must be locked and the calling LWP must be the one that last locked the
mutex (the owner). If any other LWPs are waiting for the mutex to become available, one of them is unblocked.
RETURN VALUES
Upon successful completion, 0 is returned. A non-zero value indicates an error.
ERRORS
If any of the following conditions are detected, _lwp_mutex_lock(), _lwp_mutex_trylock(), and _lwp_mutex_unlock() fail and return the cor-
responding value:
EINVAL The mp argument points to an invalid LWP mutex.
EFAULT The mp argument points to an illegal address.
If any of the following conditions occur, _lwp_mutex_trylock() fails and returns the corresponding value:
EBUSY The mp argument points to a locked mutex.
