What could be the possible reasons of remote linux host shows terminal prompt with around 15 seconds delay
A delay of around 15 seconds before the terminal prompt appears on a remote Linux host can be caused by various factors. Here are some possible reasons for this delay: 1. **Network Latency**: Slow network connections or high latency between your local terminal and the remote host can lead to delays in command execution and prompt display. 2. **SSH Configuration**: Issues with SSH configurations, such as DNS resolution, can result in delays when connecting to the remote host. Check the `UseDNS` setting in the SSH server configuration (usually in `/etc/ssh/sshd_config`) and set it to `no` to disable DNS resolution. 3. **DNS Resolution**: If DNS resolution is slow or misconfigured, it can lead to delays in resolving hostnames when connecting to the remote server. Ensure that your DNS configuration is correct. 4. **Host Unavailability**: If the remote server experiences high load or resource constraints, it may take time to respond to incoming SSH connections and display the prompt. 5. **
