This is from a Fedora 20 client testing to a Centos 6.5 server. I can do a ping6 with no problems, but I cannot 'ssh -6' to the server (ssh -4 works). I have reason to suspect the challenge is in my PPPoE link with a restricted MTU size that v6's PMTU is not working right with. So my question is: Is there a way to specify the MTU size for things like ssh (and http) to use?
The odds are that your PPoE stuff has problems with IPV6 addressing (as many things do). I really doubt the MTU has anything to do with it since MTU sets the maximum size of a packet and has nothing to do with the addressing mechanisms. You could have a router that doesn't like big packets, but that would affect both IPV4 and IPV6. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@xxxxxxxxxxxxxx - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - "Men occasionally stumble over the truth, but most of them pick" - - themselves up and hurry off as if nothing had happened." - - -- Winston Churchill - ---------------------------------------------------------------------- -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
