Hello,
      I have a DVR server with linux embeded. It has some telnet functions but i don't have the password for it (the chinese manufacturer refuses to give me the password). I did get a upgrade folder from them and found a passwd file inside.
      So i assume that when i upgrade the firmware the password in that file will be used.
      Now i am trying to modify the file so taht i can insert a password i already know.
      The problem is that i don't know how to create the password hash from what i figured the password hash is $1$1/lfbDKX$Hmd.FqzB8IZEohPesYi961
      The file is named rom.ko and i found a command

telnetd
/mnt/yaffs/web/boa -c /mnt/yaffs/web &
/bin/cp -f /mnt/yaffs/rom.ko /etc/shadow

in a script file so i assume this is the right way.
Can you help me reconstruct a password that i know already? Tell me how or make one for me :) ?...

passwd file:

root:$1$1/lfbDKX$Hmd.FqzB8IZEohPesYi961:0:0:99999:7:-1:-1:33637592
