Write a note on ‘ld.so.conf’ file.

37.Write a note on ‘ld.so.conf’ file.
Ans.
1. This configuration file is used by ‘ldconfig’, which configures dynamic linker runtime bindings.

2. It contains a listing of directories that hold shared libraries.

3. Shared library files typically end with ‘.’ So, whereas static library files typically end with ‘.a’, indicating they are an archive of objects.

4. We need to edit the file if we have installed a program that has installed a shared library to a different library directory that is not listed in the ‘ld.so.conf’ file.

5. In this case we will get an error at runtime that library does not exists.

How to configure Network file system version 4 (NFSv4) client?

69.How to configure Network file system version 4 (NFSv4) client? Ans. 1. There are two new options listed in NFSv4 are introduced as: clientaddr and ports 2. The version 3 of NFS introduced NFS over TCP, which improved NFS’s reliability. 3. In NFSv3, users use the mount option i.e., tcp as client whether client wants to use TCP or UDP to communicate with the server. NFSv4 replaces tcp or udp with a single option i.e. ports=tcp or udp 4. The default buffer size for NFSv4 is 8192 bytes, but it can grow to as large and by 32,678 bytes, which results performance improvements. 5. Following are the mount options: clientaddr=n – Declares client to be multihomed proto=type – Declares port as either udp or tcp resize=n – declares read size of clients buffer wsize=n – Declares write size of clients buffer sec=mod – Declares security model as either krb, krb5 etc.
