I write a script which will stop an application, then restart it.
Sometimes it is succesful, sometimes not.
The problem is, when stop the application, some ports are still listenning (or not released). When start the application, it reports that ports are used, and can't continues.
I use
to delay the start job, but seems somtime I need wait for more than 5 minutes to release the ports.
Are there any way to detect the ports, and wait until the ports are all released?
I believe i have most of samba configured right but i get this error each time time try to run it. I was given suggestion that i touch the file, i did, but i still cannot rid myself of this error.

Hi,
I need to run an application (Hudson) listening to port 8080 on a remote Solaris server. I have managed to start that application and tried to access it with my browser from my local PC, but unsuccessfully.
I need to find out what is blocking the access to that port (or any other). A... (9 Replies)
Hi there,
I'm driven crazy by a new problem.
It seems very complex to me and I see no way to come around.
In my script, I receive the path to a tgz file and I want to output the md5 sum of the file inside the tgz. I want a way to detect if tar fails.
I'm using the following command

Does anyone know if there is a C API call to get the status of a TCP port? As opposed to running netstat and parsing the results. At the moment I have to attempt to bind() and pick up on the address in use error which isn't very elegant
Thanks

Hi gurus,
1st:
Is possible to detect port scanning just by using utilities included in linux (netstat, iptables...), Yes there is utility called psad but I would write some scripts for my own and learn something new :)

Hello,
Is there any API or any other approach to detect whether the network cable is connected to the network adapter, say, en0, en1 or en2?

portreserve
PORTRESERVE(1) TCP port reservation utility PORTRESERVE(1)NAME
portreserve - reserve ports to prevent portmap mapping them
SYNOPSIS
portreserve
DESCRIPTION
The portreserve program aims to help services with well-known ports that lie in the bindresvport range. It prevents portmap (or other
programs using bindresvport) from occupying a real service's port by occupying it itself, until the real service tells it to release the
port (generally in its init script).
It is intended that portreserve runs from an initscript of its own, and services wishing to interact with it should use portrelease.
When the portreserve daemon is started, it examines the /etc/portreserve/ directory. Each file not containing "." or "~" in its name is
considered to be a service configuration file, and must contain a service name (as listed in /etc/services) or a port number. UDP services
may be specified by appending "/udp" to the service name, and TCP services by "/tcp". Several services may be specified, one per line.
For example, /etc/portreserve/cups might contain the string "ipp" or, equivalently, "ipp/tcp" and "ipp/udp" on separate lines.
For each service configuration file, a socket is created and bound to the appropriate port. A service wishing to bind to its port must
first run portrelease, which instructs portreserve to release the port associated with the service.
Once all the reserved ports have been released, the daemon exits.
