  • Why NFS servers generally have a 'reply cache'

    In the beginning, NFS operated over UDP, with each NFS request and each NFS reply in a separate UDP packet (possibly fragmented). UDP has the charming property that it can randomly drop arbitrary packets (and also reorder them). If UDP drops a NFS client's request to the server, the NFS client will resent it (a 'retransmit' in the jargon of NFS). If UDP drops the server's reply to a client's request, the client will also resend the request, because it can't really tell why it didn't get a reply; it just knows that it didn't.

  • How to review Apache tomcat access logs – Linux Hint

    Nowadays, there is a tremendous pace in the software development cycle. All the Organizations have codebases containing a huge number of codes consisting of web pages interlinked. There are many circumstances when a system crashes or behaves unexpectedly.
    To analyze and debug the issue, developers and system administrators look into the Log files to find the system’s problems. In reality, when a system is down, log files are often used as the primary source of information.

    In every system, system administrators maintain all the activities related to requests received from various users and store them in a file called log files.

    To debug the system, we can refer to the individual log files to gain insight into the system and move through the various timestamps to know the system’s state.

    In this article, we’ll go into the specifics of these logs below: we’ll go through what’s stored in Apache access logs, where to find them, and how to review Apache tomcat access logs. It makes the system admins keep track of all the information and activities happening within their system.

  • Is List Only Directories Recursively in Linux?

    The word “recursive” refers to the fact that a Linux or Unix operating system commands deals with the contents of folders, and if a folder has subfolders and documents, the instruction still functions with all of those documents (recursively). It could be possible that the child directory has its own set of files and folders (for example, large folders), so on and so forth. You will use different Linux instructions to recursively traverse each folder before making it to the edge of the specified folder. At that level, Linux instructions return to a turnoff of the tree and repeat the process for any sub-folders that exist. In this tutorial, you will learn all the methods to list the directories recursively.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
