In some distributions it is known as hping3 and not installed by default. hping3 is a network tool able to send custom TCP/IP packets and to display target replies like ping program does with ICMP replies.It also uses the same switches like ping for basic functionalities like -h for help and -c for count etc. Here are few basic examples for hping3.hping3 localhost -c 3HPING localhost (lo 127.0.0.1): NO FLAGS are set, 40 headers + 0 data byteslen=40 ip=127.0.0.1 ttl=64 DF id=10586 sport=0 flags=RA seq=0 win=0 rtt=3.5 mslen=40 ip=127.0.0.1 ttl=64 DF id=10657 sport=0 flags=RA seq=1 win=0 rtt=2.3 mslen=40 ip=127.0.0.1 ttl=64 DF id=10668 sport=0 flags=RA seq=2 win=0 rtt=2.4 ms--- localhost hping statistic ---3 packets transmitted, 3 packets received, 0% packet lossround-trip min/avg/max = 2.3/2.7/3.5 msFor sending TCP packet to specific port like

These options can fall short when it comes to growing with new users that aren’t already visiting a brand’s website or using its app. (This is typically when brands turn to third-party data that’s generated by cross-site tracking—the very practice users are rebelling against.)There is, however, an opportunity for privacy-respecting advertising that’s still capable of reaching new audiences. Ads that preserve privacy refrain from tracking users or building profiles, but can still be personalized and targeted. Private ads collect data that’s aggregated and anonymous, but still deliver insightful performance analytics to advertisers.In other words, it’s possible to have a thriving, healthy, and private online ad economy—third-party tracking isn’t a necessary part of the equation.Brave Ads, for example, is the first global digital ads platform built for privacy and a cookie-less future. It enables brands to carry out ad campaigns that reach otherwise unreachable audiences in a privacy-preserving way. It’s highly effective advertising without the trackers, cookies, and other creepy stuff that follows users across the Web.Those who make up the Brave Ads audience also happen to be the same people who are unreachable via traditional ad channels. They’re privacy seekers who use the Brave browser to block ads. They’re cord-cutters—80% don’t pay for cable or satellite TV. And they’re disconnectors—only 20% use Snapchat, TikTok, or Pinterest.And while this may sound like the profile of vanguard users, it’s in fact becoming the norm.How Brave Ads workBrave offers familiar ad units, like keyword-based search ads in Brave’s independent search engine, Brave Search. Brave’s search ads are privacy-preserving, text-based ads that appear at the top of a user’s search engine results page (SERP). Brave also offers a variety of other ad units that include full-page images that appear on new browser tabs, native ads in the Brave News feed, and familiar, device-level push notifications.The bundle of available Brave Ads are downloaded to the browser (and refreshed nearly every hour). But the ad matching only happens locally on-device, and ad performance isn’t associated with any given individual. No personal data makes it back to Brave’s servers (or even leaves the user’s device). Users get privacy; advertisers still get actionable insights on ad performance and ROI. And audiences are highly engaged.The aggregated reporting that Brave Ads generate provides useful details about views, clicks, site-visits, and conversions. More insights are available via privacy-respecting surveys that measure brand lift. Brands that advertise with Brave also enjoy boosted perception among unreachable audiences for making the effort to advertise in a privacy-respecting way. It’s a win-win ad model geared for the privacy-first future.Note: Brave Ads don’t replace the on-page, third-party ads that are blocked by Brave Shields. Instead, they’re unobtrusive, native ad units woven seamlessly into the Brave browser

Make sure that once you’ve launched your app, it remains running and keeps performing.What can go wrong?In order to know how and what we should monitor, it helps to have an understanding of what could potentially go wrong. The short answer is probably “well, a lot” — and as such, it’s a really tough question to answer definitively. At the same time, though, there are a range of things that we can anticipate might go wrong.Broadly speaking, we can divide these issues into a number of categories:Hitting “hard” limits; for example a full disk, hitting a physical memory limit or reaching the maximum number of processesNetwork issues; for example a site becoming unreachable, high packet losses, server connections going down or DNS failuresComponent or service failures; perhaps your database server has gone down, for example.Problems with third-party services; your S3 bucket is unreachable, your mail provider is experiencing issues, or your CDN has gone downProblems with your applications; errors and exceptions, inconsistencies in your data or even bugs in your codeKeeping third-party code or operating system components up-to-date; in particular checking for security patches or service packsThere are even silly examples of human error which, alas, do still happen; such as forgetting to renew a SSL certificate.Once you have an idea of what can go wrong, you start to get a feel for what to monitor.Important Things to ConsiderWhilst a lot of monitoring deals in metrics such as server response times, the amount of available memory or the level your CPU is running at, there’s nothing quite as important as the experience your users are having. In all likelihood there will be some correlation between the raw data from your server or application and the wait times your user faces — for example, high network latency probably means slow response
