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?
I was told that:
To figure out where I could put new MTU values:
“find /sys |grep mtu”
To set the MTU for my eth0, as root:
“echo 1300 > /sys/devices/pci0000:00/0000:00:03.0/0000:02:00.0/net/eth0/mtu”
"ifconfig eth0" reports an MTU of 1300 now.
And this works. But it is not my problem. Still not getting a TCP connection.
Going to have to check with wireshark. Maybe it will help me...
