I have a server that I can connect via SSH over IPv4 address. Now I want to SSH over IPv6.
I'm sure that my server is assigned with a valid IPv6 address, and I've configured sshd to listen on v6 address (I set it to [::]:311), but when I run (on my laptop)
ssh -v -6 -p 311 PUBLIC_V6_IP -l same_user_as_v4 -i ~/.ssh/id_rsa
I got the following output:
OpenSSH_5.8p2, OpenSSL 1.0.0d 8 Feb 2011 debug1: Reading configuration data /home/winus/.ssh/config debug1: Applying options for * debug1: Reading configuration data /etc/ssh/ssh_config debug1: Connecting to PUBLIC_V6_IP [PUBLIC_V6_IP] port 311. debug1: connect to address PUBLIC_V6_IP port 311: Permission denied ssh: connect to host PUBLIC_V6_IP port 311: Permission denied
Some extra info:
- My laptop is running Arch Linux, while my server is Ubuntu Server 10.10
- sshd -V on the server shows
OpenSSH_5.5p1 Debian-4ubuntu5, OpenSSL 0.9.8o 01 Jun 2010
- ssh -V on my laptop shows
OpenSSH_5.8p2, OpenSSL 1.0.0d 8 Feb 2011
- ssh -6 ::1 on my laptop is OK.
- ping6 PUBLIC_V6_IP is OK.
- ssh -6 ::1 -p 311 on the server is OK.
- ssh -6 PUBLIC_V6_IP -p 311 on the server is also OK.
