#I cannot access telnet on mac how to#

Secure Shell or SSH is a secure protocol and the replacement for Telnet and other insecure remote shell protocols. Enable Telnet and SSH: SSH Configuration. Httpd 72969 _www 8u IPv6 0x513627eaa81c8205 0t0 TCP *:http (LISTEN)ДЄlso, quit all web browsers or be prepared to filter those network connections from the above lsof command as it shows all connections over port 80. That is it, the telnet services configuration on Cisco router. Also, you will most certainly want to check whatever web server you are running to ensure it's really listening to port 80: mac:~ me$ sudo lsof -i :80 | egrep 'PID|LISTEN'Д¬OMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME It might be worth checking if you have LittleSnitch or another firewall that has rules that are blocking network access or reboot into Safe mode to test if some kernel extensions or other conflict is preventing the default reachability and access to local ports. Should you get different results, I would use scutil to determine reachability for your network destination: mac:~ me$ scutil -r localhost Telnet: connect to address fe80::1: Connection refused Telnet: connect to address 127.0.0.1: Connection refused Telnet: connect to address ::1: Connection refused If you have no web server running, here is what you should get from terminal to show that name resolution is working on all network interfaces before the telnet gives up connecting to port 80: mac:~ me$ telnet localhost 80 I have no such problems connecting to a web server when it's actually listening on port 80. This leads me to believe that the heart of the issue was a borked /etc/hosts file. I actually had this problem after setting up a new user from a backup drive on my machine at work (which is running Mountain Lion) and (just today) followed the same steps above (minus blowing away ruby and rebooting the machine), and it worked. Note: the above hosts file contains virtually the same thing that I say my hosts file contained before (see original question) however, there were other things in my original hosts file that I did not share in my question (I just shared what I thought was the relevant part), so perhaps something there got borked when I upgraded-I wish I knew for sure. I also took JakeGould's advice and blew away ruby 2.0.0 (I still had ruby 1.8.7-you cannot uninstall ruby entirely on a mac, since it uses ruby for other things) and rvm and reinstalled those but I'm not sure that had anything to do with my success, as I still had the same issues until I followed the steps outlined above. I can only guess that something weird happened with my old hosts file. After that, things appear to be working normally again. Then, I ran dscacheutil -flushcache and rebooted my computer*. # localhost is used to configure the loopback interface I moved my old hosts file ( /etc/hosts) to hosts.old and made a new one in its place that simply contained: # Thanks to bmike, I did a bit of searching on why my loopback was unreachable and came across this article. Type show run to output the running configuration of the switch. The credentials can be found in your UniFi controllerвЂ™s settings.
