Bash script, find the next closed (not in use) port from some port range.
hi,
i would like to create a bash script that check which port in my Linux server are closed (not in use) from a specific range, port range (3000-3010).
the print output need to be only 1 port, and it will be nice if the output will be saved as a variable or in same file.
my code is:
than to run it i use: ./demo2.sh 127.0.0.1 3000 3010
sco unix 5.0.x, several weeks ago, I add a telnet-like service in inetd.conf, it runs well for 100 network terminals.
But nowdays, the terminals can connect to server successfully after booting machine, but several hours later, can not connect. "netstat -p tcp -a" can NOT find the port in... (1 Reply)

Hi Guys,
Please could you tell me if it is possible to have a single rule/filter to allow a certain port range instead of a separate rule for each port?
I'm sure it must be possible but I am unable to find the syntax.
Thanks

I want to limit all *outbound* traffic on eth0 (or all *.*) on port 25 to a specific (allowed) range...
I.E.
192.168.1.5 (local ip) tries to connect to 1.2.3.4:25 (outside real world ip)
It can proceed because 1.2.3.0/24 is the allowed range
Now, 192.168.1.5 (local ip) tries to connect to... (1 Reply)
In my Linux system ephemeral port range is showing different ranges as follows
$ cat /proc/sys/net/ipv4/ip_local_port_range

cat /etc/sysctl.conf | grep net.ipv4.ip_local_port_range
net.ipv4.ip_local_port_range = 9000 65500
Which will be the effective ephemeral port... (5 Replies)

mssql_connect
MSSQL_CONNECT(3)MSSQL_CONNECT(3)mssql_connect - Open MS SQL server connectionSYNOPSIS
resource mssql_connect ([string $servername], [string $username], [string $password], [bool $new_link = false])
DESCRIPTION mssql_connect(3) establishes a connection to a MS SQL server.
The link to the server will be closed as soon as the execution of the script ends, unless it's closed earlier by explicitly calling
mssql_close(3).
PARAMETERS
o $servername
- The MS SQL server. It can also include a port number, e.g. hostname:port (Linux), or hostname,port (Windows).
o $username
- The username.
o $password
- The password.
o $new_link
- If a second call is made to mssql_connect(3) with the same arguments, no new link will be established, but instead, the link
identifier of the already opened link will be returned. This parameter modifies this behavior and makes mssql_connect(3) always
open a new link, even if mssql_connect(3) was called before with the same parameters.
RETURN VALUES
Returns a MS SQL link identifier on success, or FALSE on error.
