Your problem is that your / device is mirrored (c1t0d0s0 and c1t1d0s0). If you only change /etc/passwd on one device, your mirror is out of sync and cause file system inconsistency. If your file system didn\'t come up clean, the depended services such as inetd, telnet will not start. You can use svcs -xv to see the reason. You may want to try this:\r\n\r\nboot cdrom  -s\r\nfsck -F ufs -y /dev/rdsk/c1t0d0s0\r\nmount /dev/dsk/c1t0d0s0 /a\r\nvi /a/etc/shadow and delete root password\r\numount /a\r\nfsck -F ufs -y /dev/rdsk/c1t1d0s0\r\nmount /dev/dsk/c1t1d0s0 /a\r\nvi /a/etc/shadow and delete root password\r\numount /a\r\n\r\nreboot

为什么不用SUE工具盘挂接带metadb的系统呢？
