What is “libnsl.so.1” for RHEL?
“libnsl.so.1” is a shared object library file for the libnsl library. libnsl is a library that provides a number of network services, including the functionality for programs to make network connections using the transport layer protocol TCP, as well as other functionality related to networking. It provides a number of standard C library function calls that are used by programs to perform these services.
On Red Hat Enterprise Linux (RHEL) systems, libnsl is a system library that is required by many network-related programs and utilities, such as the rpcbind service and the rsh and rlogin utilities. It provides the implementation of the functions of the Network Services Library API, which provides a number of services that are used by programs that need to communicate over the network.
It’s also worth noting that, libnsl is commonly used by programs written in C, but can also be used by programs written in other languages as well through the use of wrapper libraries.
