How can I telnet to an IPv6 host using Mac OS X?
- by Nate
I’m testing IPv6 on a corporate network and having problems with OS X. With most IPv6 commands, such as telnet -6 or traceroute6, I get the error:
connect: No route to host
For example, I have a web server. This fails:
$ telnet -6 fe80::… 80 # this fails
I know the server is reachable because ping6 works (note that I have to use the -I argument):
$ ping6 -I en1 fe80::… # this works
And I know the web server is running because I can telnet to it from Windows:
C:\> telnet fe80::… 80 # this works
I suspect there is some configuration flag or command-line argument that I am missing.
