I am using the while-loop to read a file.
The file has lines with null-terminated strings (words, actually.)
What I have by that reading - just a first word up to '\0'!
I need to have whole string up to 'new line' - (LF, 10#10, 16#A)
What I am doing wrong?

Along with pulling out the variable, I need to convert some url coding like a + to a space, etc.... (4 Replies)

Hi all
I have spent half a day trying to create a shell script which reads a configuration file on a line by line basis.
The idea of the file is that each will contain server information, such as IP address and various port numbers. The line could also be blank (The file is user created). Here... (1 Reply)

tcpdrop
TCPDROP(8) BSD System Manager's Manual TCPDROP(8)NAME
tcpdrop -- drop TCP connections
SYNOPSIS
tcpdrop local-address local-port foreign-address foreign-port
tcpdrop [-l] -a
DESCRIPTION
The tcpdrop command may be used to drop TCP connections from the command line.
If -a is specified then tcpdrop will attempt to drop all active connections. The -l flag may be given to list the tcpdrop invocation to drop
all active connections one at a time.
If -a is not specified then only the connection between the given local address local-address, port local-port, and the foreign address
foreign-address, port foreign-port, will be dropped.
Addresses and ports may be specified by name or numeric value. Both IPv4 and IPv6 address formats are supported.
The addresses and ports may be separated by periods or colons instead of spaces.
EXIT STATUS
The tcpdrop utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
If a connection to httpd(8) is causing congestion on a network link, one can drop the TCP session in charge:
# sockstat -c | grep httpd
www httpd 16525 3 tcp4
192.168.5.41:80 192.168.5.1:26747
The following command will drop the connection:
# tcpdrop 192.168.5.41 80 192.168.5.1 26747
The following command will drop all connections but those to or from port 22, the port used by sshd(8):
# tcpdrop -l -a | grep -vw 22 | sh
