$ ssh-agent
SSH_AUTH_SOCK=/tmp/ssh-JvfzN17863/agent.17863; export SSH_AUTH_SOCK;
SSH_AGENT_PID=17864; export SSH_AGENT_PID;
echo Agent pid 17864;

使ssh-agent生效

eval `ssh-agent`

6.1. ssh-add

私鑰管理

neo@netkiller:~$ ssh-add
Identity added: /home/neo/.ssh/id_dsa (/home/neo/.ssh/id_dsa)

neo@netkiller:~$ ssh-add -l
1024 e5:16:5a:ca:5c:ca:a6:66:89:2d:bf:f2:22:94:3c:d6 /home/neo/.ssh/id_dsa (DSA)

let's add a few one-off keys

$ ssh-add ssh-keys/id*

Delete all keys from the agent

neo@netkiller:~$ ssh-add -D
All identities removed.

6.2. Lock / Unlock agent

neo@netkiller:~$ ssh-add -x
Enter lock password:
Again:
Agent locked.
neo@netkiller:~$ ssh-add -X
Enter lock password:
Agent unlocked.

6.3. Set lifetime (in seconds) when adding identities.

neo@netkiller:~$ ssh-add -t 10
Identity added: /home/neo/.ssh/id_dsa (/home/neo/.ssh/id_dsa)
Lifetime set to 10 seconds

neo@netkiller:~$ ssh-add -l
1024 e5:16:5a:ca:5c:ca:a6:66:89:2d:bf:f2:22:94:3c:d6 /home/neo/.ssh/id_dsa (DSA)

neo@netkiller:~$ ssh-add -l
The agent has no identities.
