内容

sshで繋がるホストと、scpできません。
ググると、接続先の.bashrcで他のシェルをロードしていたりしているのが原因などとありましたが、そのようなこともしていません。
-vオプションで内容を見てみるとIPv6で繋がっていることに気づきました。
ためしに、-4オプションでIPv4でつなぐようにすると問題なくscp出来ました。
IPv6でscpするにはどうすれば良いでしょうか。

実行結果

-vをつけてscpを実行した結果は以下の通りです。"Sending command"の部分で止まってしまいます。

> scp -pv hoge.example.com:/opt/backup/backup.conf .
