Hello, sorry if this has been posted before but i was wondering if there is a way to run a program until a segmentation fault is found.
Currently i'm using a simple shell script which runs my program 100 times, sleeps 1 second because srand(time(0)) is dependent on seconds. Is there a possible... (1 Reply)
We have a Solaris 8 server which users login to via VNC to get a desktop. On that desktop these users use Netscape Communicator 4.9 to access a very important mail account. Unfortunately Netscape has started segfaulting regularly.

Hello everyone,
I'm writing a program using the id3lib unfortunately I've encountered with memory issue that cause segmentation fault. I tried to rerun and analyze the program with valgrind but it doesn't point me anywhere. I really stuck on this one.

I have a program that allows users to specify the debug log file location and name.
I have tried using the access() and stat() but they both segfault if the drive say (d:\) is invalid. Both seem to be fine if the drive exists.
Could someone please point me in the direction to a function that... (1 Reply)
hello all,
my question is not about How code can be rewritten, i just wanna know even though i am not using read only memory of C (i have declared str) why this function gives me segfault :wall:and the other code executes comfortably though both code uses same pointer arithmetic.

Hi,
I've been trying to filter a file which has several repetitions of lines which looks as follows:
('hello

Each line has different values in them. I want grep or awk or sed to treat everything within the (' and >>) as one line and then filter for a... (2 Replies)

I was able to modify some code... (6 Replies)

mod_security - Security Audit and Trailing Functionality
DESCRIPTION
Security Audit and Trailing Functionality
EXPORTS
list_auth_users(Port) -> Users | []
list_auth_users(Address, Port) -> Users | []
list_auth_users(Port, Dir) -> Users | []
list_auth_users(Address, Port, Dir) -> Users | []
Types Port = integer()
Address = {A,B,C,D} | string() | undefined
Dir = string()
Users = list() = [string()]
list_auth_users/1 , list_auth_users/2 and list_auth_users/3 returns a list of users that are currently authenticated. Authentica-
tions are stored for SecurityAuthTimeout seconds, and are then discarded.
list_blocked_users(Port) -> Users | []
list_blocked_users(Address, Port) -> Users | []
list_blocked_users(Port, Dir) -> Users | []
list_blocked_users(Address, Port, Dir) -> Users | []
Types Port = integer()
Address = {A,B,C,D} | string() | undefined
Dir = string()
Users = list() = [string()]
list_blocked_users/1 , list_blocked_users/2 and list_blocked_users/3 returns a list of users that are currently blocked from access.
block_user(User, Port, Dir, Seconds) -> true | {error, Reason}
block_user(User, Address, Port, Dir, Seconds) -> true | {error, Reason}
Types User = string()
Port = integer()
Address = {A,B,C,D} | string() | undefined
Dir = string()
Seconds = integer() | infinity
Reason = no_such_directory
block_user/4 and block_user/5 blocks the user User from the directory Dir for a specified amount of time.
unblock_user(User, Port) -> true | {error, Reason}
unblock_user(User, Address, Port) -> true | {error, Reason}
unblock_user(User, Port, Dir) -> true | {error, Reason}
unblock_user(User, Address, Port, Dir) -> true | {error, Reason}
Types User = string()
Port = integer()
Address = {A,B,C,D} | string() | undefined
Dir = string()
Reason = term()
unblock_user/2 , unblock_user/3 and unblock_user/4 removes the user User from the list of blocked users for the Port (and Dir) spec-
ified.
THE SECURITYCALLBACKMODULE
The SecurityCallbackModule is a user written module that can receive events from the mod_security Erlang Webserver API module. This module
only exports the function(s), event/4,5 , which are described below.
EXPORTS
event(What, Port, Dir, Data) -> ignored
event(What, Address, Port, Dir, Data) -> ignored
Types What = atom()
Port = integer()
Address = {A,B,C,D} | string() <v>Dir = string()
Data = [Info]
Info = {Name, Value}
event/4 or event/4 is called whenever an event occurs in the mod_security Erlang Webserver API module ( event/4 is called if Address
is undefined and event/5 otherwise). The What argument specifies the type of event that has occurred, and should be one of the fol-
lowing reasons; auth_fail (a failed user authentication), user_block (a user is being blocked from access) or user_unblock (a user
is being removed from the block list).
Note:
Note that the user_unblock event is not triggered when a user is removed from the block list explicitly using the unblock_user function.
