SSH vs Telnet

Developers should learn SSH for securely accessing and administering remote systems, such as Linux servers, cloud VMs, or containers, especially in DevOps, sysadmin, and backend roles meets developers should learn telnet for legacy system maintenance, network troubleshooting, and understanding foundational remote access concepts, as it is still used in some embedded systems, routers, and older infrastructure. Here's our take.

SSH

Nice Pick

Developers should learn SSH for securely accessing and administering remote systems, such as Linux servers, cloud VMs, or containers, especially in DevOps, sysadmin, and backend roles

Pros

• It is critical for tasks like deploying applications, troubleshooting issues, and automating scripts via remote execution, offering a more secure alternative to older protocols like Telnet or FTP
• Related to: linux-command-line, networking-basics

Cons

• Specific tradeoffs depend on your use case

Telnet

Developers should learn Telnet for legacy system maintenance, network troubleshooting, and understanding foundational remote access concepts, as it is still used in some embedded systems, routers, and older infrastructure

Pros

• It is valuable for testing network services (e
• Related to: ssh, tcp-ip

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. SSH is a tool while Telnet is a protocol. We picked SSH based on overall popularity, but your choice depends on what you're building.

The Bottom Line

SSH wins

Based on overall popularity. SSH is more widely used, but Telnet excels in its own space.
