iPhoneのOpenSSHを安全に使う設定(jailbreak後)を見てもよく分からなかったので
クライアント（PC,Mac,Linuxなど）側から
$ ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/Users/xxx/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /Users/xxx/.ssh/id_rsa. Your public key has been saved in /Users/xxx/.ssh/id_rsa.pub. The key fingerprint is: 2b:b4:84:10:57:79:36:00:73:c8:e7:7f:c0:db:da:fb xxx@xxxxx.toyholic.com The key's randomart image is: +--[ RSA 2048]----+ | ..+++o | | oooo + | | . o + . | | . .. o | | . o.S+ | | o .o.o | | o .+ | | .. . | | .oE | +-----------------+ $ cd .ssh/ $ pwd /Users/xxx/.ssh $ ls id_rsa id_rsa.pub known_hosts
公開鍵をiPhoneに転送する。パスワード認証を切っていないのでパスワードを入れて
$ scp id_rsa.pub mobile@xxxxx.toyholic.com:/var/mobile/.ssh mobile@xxxxx.toyholic.com's password: id_rsa.pub 100% 404 0.4KB/s 00:00
sshサーバー(iPhone)側に移動して
$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
公開鍵で入れるかな。
$ ssh -v mobile@xxxxx.toyholic.com

セキュリティ的にmobileってユーザー危ないけど削除したら大変だろうな。
chmod -R 755 /private/var/でCydiaも何もかも起動しなくなったんだな。う〜ん
