问题 there must be various ways to find string in txt file by using python, but what is the best way? ( for speed, for resources .. ) My first idea was as below. file = open('/home/socfw/src/edl/outbound_monthly.txt') inputIP = '127.0.0.1' while (1): line = file.readline() if inputIP in line: print("ok") break But, it's too slow to use web service properly (it is actually backend logic of my web service) txt file looks like as below test.txt ( IPV4 addresses are in here, and they counts almost 60k

问题 I have an IPv4 address. Ex. 172.19.20.21 I used to do this $fs = @fsockopen($ip,$port,$errno,$errstr,3); if( !$fs ){ $error = 'SSC is down'; return Redirect::to('/')->with('error', $error ) ->withInput(Request::except('password')); } It works perfectly fine. Now, I have an IPv6 Address Ex. 3000::1 if ((strpos($ip, ":") > -1)){ // Code for IPv6 check $fs = @fsockopen($ip,$port,$errno,$errstr,3); if( !$fs ){ $error = 'SSC is down'; return Redirect::to('/')->with('error', $error ) ->withInput

What is the meaning of 0.0.0.0 address while receiving broadcast (or other packets)?

被刻印的时光 ゝ 提交于 2021-01-29 13:58:35
问题 I have two scripts, first sends a broadcast, second is receiving UDP packets. It is working only when the receiving script has his IP address set (via bind) to 0.0.0.0 . Why? This address should be something like "not existing address", so how can the script have it set like his own address? Why 127.0.0.1 (or exactly 192.168.0.xx ) does not work? Thank you, RA 回答1: Probably your machine has two or more interfaces with different IPs, as you already know the 127.0.0.1 IP means your local

Get only IPv4 ips via NodeJS express

允我心安 提交于 2020-06-27 10:01:07
问题 I have a NodeJS express service running on Centos and listens to GET requests and I need to identify the IP of the user. Currently, I'm using this script ip = req.headers['x-forwarded-for'] || req.connection.remoteAddress || req.socket.remoteAddress || req.connection.socket.remoteAddress The problem is that sometimes the IP returned is IPv4 and sometimes it is IPv6. Is there a way to get only IPv4 IPs? 回答1: Update Base on Micheal's comment, if client is connected via ipv6 there will not be an
