I want to kill TCP connections which have status as TIME_WAIT & no PID
(as per the output of the "netstat - p" command).
Is there any command/utility available to kill connections to a specific port or IP address.
The problem is that these connections don't have process ID (see below).
Hi,
there are two ways of "killing" TIME_WAIT connection:
1) change time of ip_conntrack_timeout_time_wait (via sysctl or by writing number of seconds to /proc/sys/net/ipv4/netfilter/ip_conntrack_tcp_timeout_time_wait by "echo" command)
2) use "lsof" (list opened files) command, eg:
But I don't see the reason why to "kill" TCP_WAIT connection - it will timeout itself after some time (see ip_conntrack_timeout_time_wait)
What is the maximum number of TCP ports that can be consumed at any one time? How can I determine what the number is or increase it?
I was under the impression that with our system (UnixWare 7.1.1) 1024 was the maximum under our current Kernel tuning parms, but I think that is really just... (4 Replies)
1. If I use an software application(which connects to the database in the server) in my local pc, how many PID should be registered? Would there be PID for the session and another PID for socket connection?
2. I noticed (through netstat) that when I logged in using the my software application,... (1 Reply)

Hi,
I wrote a script to kill a process id.
I am able to kill the PID only if I enter the root password in the middle of the execution because I did not run as root i.e after i run the script from the terminal, instead of killing directly, it is killing only after entering the pass when it... (12 Replies)

scan_ip6
scan_ip6(3) Library Functions Manual scan_ip6(3)NAME
scan_ip6 - parse an IPv6 number in ASCII representation
SYNTAX
#include <ip6.h>
int scan_ip6(const char *src,char ip[16]);
DESCRIPTION
scan_ip6 parses an IPv6 number in RFC1884 ASCII representation from src and writes the result into ip. It returns the number of bytes read
from src or 0 if the parsing failed.
scan_ip6 accepts upper and lower case hex letters, it understands "::" compression and partial IPv4 addresses as in "::FFFF:129.144.52.38".
To allow transparent usage of IPv4 in IPv6 applications, scan_ip6 also understands IPv4 addresses in dotted-decimal notation and will
return an IPv4-mapped IPv6 address (i.e. "127.0.0.1" will be parsed as "::FFFF:127.0.0.1".
Unlike many other IP parsing routines, scan_ip6 does not recognize octal (like 0177.0.0.1) or hexadecimal numbers (like 0x7f000001) in the
IPv4 part.
EXAMPLE
#include <str.h>
#include <ip6.h>
char buf[]="::1";
char ip[16];
if (scan_ip6(buf,ip) != str_len(buf))
parse_error();
