Another day, another thing to learn , this spices up my job. Today i built a dashboard , i want the user provide me a list of keywords from an input text, then i will search based on that. The challenge is it’s a list of keywords separated by comma. It’s easy if the user provide a string like this: hostname=”hostA” OR hostname=”hostB” OR hostname=”hostC” , instead the user will provide me this : hostA,hostB,hostC . I know that i have to split this our and turn the list keywords into a format that Splunk can understand. I know how to turn this hostA,hostB,hostC intoRead More →

In my last post, i shared that we can use Fiddler to bypass cloudflare protection. I used it for a few days and realized that Fiddler is not stable. I decided to do more research. It turned out that Cloudflare use some signature in TLS protocol to identify the client. Chrome/Firefox/Edge using different library. Luckily there are some library developed to simulate these TLS protocol. The tool name is curl-impersonate , check it out here https://github.com/lwthiker/curl-impersonate#Advanced-usage I have a thought about this, Cloudflare spends a lot of efforts on this to detect the bots. But now, we know where cloudflare get the data and weRead More →

Another day, another thing. I’m running a PHP site on Azure App Service, the site needs to convert some documents to pdf. We know we need wkthmltopdf, unfortunately the default image doesn’t have it, we need to do it ourself. First i install wkhtmltopdf – it seems pretty simple: apt-get install wkhtmltopdf It installed successfully, unfortunately when we run it, we got this error: QXcbConnection: Could not connect to display Aborted (core dumped) Google the error and found the recommendation is to run like this: xvfb-run wkhtmltopdf -q test.html test.pdf I tried that, unfortuately, it said xvfb-run not found. OK, let install it: apt installRead More →

if you need to write a crawler script and that script needs to crawl a site protected by cloudflare. you will face a challenge, you got 403 error. It’s because somehow Cloudflare knows that we use some tools instead of browser. Even you open the Chrome Inspector and copy the curl command , you still got the error. I did some try and found some ways pass this. if you use curl : you need to use it through a proxy (Fiddler with HTTPs decrypt) If you use wget you will need a proxy (Fiddler with HTTPs decrypt))+ change the user agent to Blackberry.

With recent data privacy law, somehow i thought that our identity will not be easily shared between sites. This is wrong, i found it today. I’m using my personal laptop for non-work related things, sometimes i use it to open our company email. Since our company will not never share our data, but somehow when i open some internet sites, i see them connect to some identity services to track the location. Surprisingly, i see it know what company i’m working for. This is the company providing that service – not sure how they make it but i bring a lot of concern to me.Read More →
