报错原因是ssh错误地使用了库文件/opt/csw/lib/libcrypto.so.0.9.7所致。

root用户执行ssh时报错：

root@mlctest01:~ #> ssh
ld.so.1: ssh: fatal: relocation error: file /usr/bin/ssh: symbol SUNWcry_installed: referenced symbol not found
Killed

检查ssh使用的库
root@mlctest01:~ #> ldd `which ssh`
        libsocket.so.1 =>        /usr/lib/libsocket.so.1
        libnsl.so.1 =>   /usr/lib/libnsl.so.1
        libz.so.1 =>     /opt/csw/lib/libz.so.1
        libz.so.1 (SUNW_1.1) => (version not found)
        libcrypto.so.0.9.7 =>    /opt/csw/lib/libcrypto.so.0.9.7
        libgss.so.1 =>   /usr/lib/libgss.so.1
        libc.so.1 =>     /usr/lib/libc.so.1
        libmp.so.2 =>    /usr/lib/libmp.so.2
        libmd.so.1 =>    /usr/lib/libmd.so.1
        libscf.so.1 =>   /usr/lib/libscf.so.1
        libdl.so.1 =>    /usr/lib/libdl.so.1
        libcmd.so.1 =>   /usr/lib/libcmd.so.1
        libdoor.so.1 => /usr/lib/libdoor.so.1
        libuutil.so.1 =>         /usr/lib/libuutil.so.1
        libgen.so.1 =>   /usr/lib/libgen.so.1
        libm.so.2 =>     /usr/lib/libm.so.2
        /platform/SUNW,SPARC-Enterprise/lib/libc_psr.so.1

查看LD_LIBRARY_PATH环境变量设置
root@mlctest01:~ #> echo $LD_LIBRARY_PATH
.:/afc/lib:/opt/csw/lib:/opt/csw/ssl/lib:/usr/local/lib:/usr/local/ssl/lib:/app/oracle/product/client/10.2.0.1/lib32:/usr/lib

把/usr/sfw/lib路径加入到LD_LIBRARY_PATH环境变量的最前面
root@mlctest01:~ #> export LD_LIBRARY_PATH=/usr/sfw/lib:$LD_LIBRARY_PATH

再次执行ssh成功
root@mlctest01:~ #> ssh
Usage: ssh [options] host [command]
Options:
-l user     Log in using this user name.
-n          Redirect input from /dev/null.
-F config   Config file (default: ~/.ssh/config).
-A          Enable authentication agent forwarding.
-a          Disable authentication agent forwarding (default).
-X          Enable X11 connection forwarding.
-x          Disable X11 connection forwarding (default).
-i file     Identity for public key authentication (default: ~/.ssh/identity)
-t          Tty; allocate a tty even if command is given.
-T          Do not allocate a tty.
-v          Verbose; display verbose debugging messages.
              Multiple -v increases verbosity.
-V          Display version number only.
-q          Quiet; don't display any warning messages.
-f          Fork into background after authentication.
-e char     Set escape character; ``none'' = disable (default: ~).
-c cipher   Select encryption algorithm
-m macs     Specify MAC algorithms for protocol version 2.
-p port     Connect to this port. Server must be on the same port.
-L listen-port:host:port   Forward local port to remote address
-R listen-port:host:port   Forward remote port to local address
              These cause ssh to listen for connections on a port, and
              forward them to the other side by connecting to host:port.
-D port     Enable dynamic application-level port forwarding.
-C          Enable compression.
-N          Do not execute a shell or command.
-g          Allow remote hosts to connect to forwarded ports.
-1          Force protocol version 1.
-2          Force protocol version 2.
-4          Use IPv4 only.
-6          Use IPv6 only.
-o 'option' Process the option as if it was read from a configuration file.
-s          Invoke command (mandatory) as SSH2 subsystem.
-b addr     Local IP address.

检查ssh版本
root@mlctest01:~ #> ssh -V
Sun_SSH_1.1.2, SSH protocols 1.5/2.0, OpenSSL 0x0090704f
