This is openssh version on my linuxbox centos 5.2

# ssh -V
OpenSSH_4.3p2, OpenSSL 0.9.8b 04 May 2006

I connected with other box through ssh with password.
But by ssh-agent, I could not make any connection.

My problem is this.

[root@localhost ~]# eval 'ssh-agent -s'
SSH_AUTH_SOCK=/tmp/ssh-mgyhm14530/agent.14530; export SSH_AUTH_SOCK;
SSH_AGENT_PID=14531; export SSH_AGENT_PID;
echo Agent pid 14531;
[root@localhost ~]# echo $SSH_AUTH_SOCK
/tmp/ssh-bHKeO13270/agent.13270
[root@localhost ~]# echo $SSH_AGENT_PID
13271
[root@localhost ~]# ssh-add
[root@localhost ~]# ssh-add -l
The agent has no identities.
[root@localhost ~]# cd /tmp/ssh-mgyhm14530
[root@localhost ssh-mgyhm14530]# ls -al
12
drwx------ 2 root root 4096 11 19 20:35 .
drwxrwxrwt 16 root root 4096 11 19 20:35 ..
srw------- 1 root root 0 11 19 20:35 agent.14530


1. Why "ssh-add -l" shows "The agent has no identities"?
2. Why "agent.14530" shows "0 byte"?

Here is my sshd-config:

Protocol 2
HostKey /etc/ssh/ssh_host_rsa_key
HostKey /etc/ssh/ssh_host_dsa_key
SyslogFacility AUTHPRIV
#LogLevel INFO
RSAAuthentication yes

Pleas help me for solving this problem.

Use backticks around `ssh-agent`, not single quotes. Or use "eval $(ssh-agent)".

jschiwal,

Thanks a lot.
