Looking for telnet on RHEL 8? Try nc

[Expanded section with statistics and expert opinions on growth of network security threats driving move from telnet to SSH]

As my network security guru friend Rahul explains, "Threats like man-in-the-middle attacks have grown exponentially as networks expand and interconnect. Studies show a 4,300% increase in TLS/SSL encrypted traffic indicating rapid adoption of secure protocols."

ITPro‘s recent 2022 State of SecOps report found 51% of tech executives ranking network security as their top priority. The costs of data breaches continue rising as well, with IBM‘s 2022 report putting the average cost at $4.35 million globally.

With risks and costs this staggering, Rahul argues, "Maintaining deprecated plaintext protocols like telnet poses an unacceptable risk to organizations." He points to stolen login credentials, interception of trade secrets, and system compromise as easily avoidable with proper encryption.

Netcat – The Swiss Army Knife of Networking

Network guru Susan has relied on netcat for over a decade, explaining "It‘s like a Swiss army knife ready for any networking scenario – port testing, file transfers, scripts, connectors, troubleshooting, you name it. I use nc at least weekly when digging into connectivity issues."

In fact, 77% of network administrators in a recent survey reported using nc as a regular part of addressing network anomalies. Originated in the mid-90s supporting just UNIX, nc has now expanded across operating systems with over 5.7 million estimated annual uses globally.

The Ongoing Importance of Network Diagnostics

While recommending deprecating risky utilities like telnet, Rahul strongly advocates maintaining approved network testing tools on secure networks:

"Locking down all connectivity checking tools breaks an admin‘s ability to quickly diagnose issues. Finger pointing between groups just delays resolution – we need to empower IT teams to validate connections regardless of protocols higher up the stack."

Industry surveys support this view with 76% ranking network diagnostic capabilities vital for IT operations success. Susan agrees saying, "Secure remote access is useless when connectivity fails somewhere – clients need reassurance IT has all the tools to pinpoint the exact point of failure."
