Information contained in the shadow file<\/p>\n\n\n\n

If anyone is interested this is how I worked out what the password was.<\/p>\n\n\n\n

I did a backup from the cmd line and transferred the cho-dat file to my laptop, I then used 7-Zip to open the archive and went to CHO-DAT\\CHO-DAT~\\\\etc\\ and opened the shadow file using notepad ++.<\/p>\n\n\n\n

The format of the file is as follows with each element separated by a :<\/p>\n\n\n\n

root:$1$jrTtj3TY$.rhLPcNiiLy8IyKWLwKXm0:16403:0:99999:7:::<\/p>\n\n\n\n

Which equates to<\/p>\n\n\n\n

    \n
  1. Username, up to 8 characters. Case-sensitive, usually all lowercase. A direct match to the username in the \/etc\/passwd file.<\/li>\n\n\n\n
  2. Password, 13 character encrypted. A blank entry (eg. ::) indicates a password is not required to log in (usually a bad idea), and a “*” entry (eg. :*:) indicates the account has been disabled, the first three characters here indicate the type of algorithm used (which in this case is MD5<\/li>\n\n\n\n
  3. The number of days (since January 1, 1970) since the password was last changed.<\/li>\n\n\n\n
  4. The number of days before password may be changed (0 indicates it may be changed at any time)<\/li>\n\n\n\n
  5. The number of days after which password must<\/em> be changed (99999 indicates user can keep his or her password unchanged for many, many years)<\/li>\n\n\n\n
  6. The number of days to warn user of an expiring password (7 for a full week)<\/li>\n\n\n\n
  7. The number of days after password expires that account is disabled<\/li>\n\n\n\n
  8. The number of days since January 1, 1970 that an account has been disabled<\/li>\n\n\n\n
  9. A reserved field for possible future use<\/li>\n<\/ol>\n\n\n\n

    Now at this point I was wondering if it would be possible to edit the file line for root with a known password (it maybe as I didn\u2019t have to go that far) but instead when I read 3 above I realized that the password had not been changed since Saturday, November 29, 2014 which is probably the date that I finished installing it originally, there are a number of web pages that do this for you if your keen the one I used is https:\/\/www.epochconverter.com\/seconds-days-since-y0<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
