Any body pls let me know the procedure to recover ROOT password in Sun Netra 20 Server..I forgot the password.

boot the mashine with a cd/dvd or via net to single user, mount the internal disk and replace the password with a known value in /etc/shadow for user root.

Or just blank out the password and then set a new one when the system has booted and you logged in without a root password.

that was my first thought... but when the mashine is public a root password is better for secutity reasons

you can't recover a forgotten password, if you cannot logon you have to bring system down to the ok prompt(using stop-a) or if you are still logged on, init 0

then

ok boot cdrom -s

once system comes up, run format command to list your disks

0. c1t0d0 <SUN72G cyl 14087 alt 2 hd 24 sec 424>
/pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w21000004cfb3801b,0
1. c1t1d0 <SUN72G cyl 14087 alt 2 hd 24 sec 424>
/pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w21000004cfb3f8f1,0

ctrl+d

mount /dev/dsk/c0t1d0s0 /mnt

vi /mnt/etc/shadow

root:qR8FoxgqZibJg:13428:7:84:::: ### example

remove everything between the 1st and 2nd ':' like so

root::13428:7:84::::

umount /mnt

sync;sync;sync; reboot

Thanks a lot
