How to check that a / is expired in AIX? I can check that the is expired or not with: ls -f NAME | fgrep expires

But how can I check that the 's is expired or not? Are there any other "expiring" things that can cause trouble? [so that can't , because he can only reach a server through FTP and his expired, and he can't change it, because he hasn't got SSH access to give out the "wd" command to update his .] /

3 Answers Is there any chage sort of command on AIX? check /etc/shadow file thats where the expiry information is stored. Update: It seems there is a wdexpired subroutine that can be loaded and Checks the 's to determine if it has expired. However, it seems to be used as root. http://publib.boulder.ibm.com/infocenter/aix/v6r1/index.jsp? topic=%2Fcom.ibm.aix.basetechref%2Fdoc%2Fbasetrf1%2Fwdexpired.htm This link has excellent documentation of what you would require http://www.torontoaix.com/scripting/when_pwd_exp As demonstrated earlier in the above article, the expiry of a is governed by the maxage attribute. For example: maxage=0 means never to expire maxage=2 means will expire in two weeks.

AIX stores the time in the epoch format in seconds, so first you must determine how many seconds in a week, as this is how maxage measures the time between expiry, that is in week numbers. There are 86400 seconds in a day, so multiplying that by seven comes in at 604800. So there are 604800 seconds in a week. The next command you need to look at is the pwd, which in turn queries the file /etc/security/wd. This file holds the values in seconds when a last changed their . Interrogating the file or using the pwd command will return the same result. For this demonstration, let us query the spoll: # grep -p "spoll:" /etc/security/wd spoll: = EvqNjMMwJzXnc lastupdate = 1274003127 flags =

CHG

# pwd -q spoll spoll: lastupdate = 1274003127 flags = CHG

You can see the lastupdate value in seconds from the above output. In other words, the last time the was changed: 1274003127 Next, using the ls or interrogating the file with /etc/security/, you can determine the number of weeks before the spoll will expire: # grep -p "spoll:" /etc/security/ spoll: = false maxage = 4 # ls -a maxage spoll

spoll maxage=4

You can see from the above output that the number of weeks before expiry is 4. The next task is then to multiply the number of seconds in a week by the number of weeks before the spoll is due to expire. In this case, it is 4: 604800 * 4 # expr 604800 \* 4 2419200

Next, you need to add the maxage value in seconds (604800 * 4) to the last time the was changed: 2419200 + 1274003127 # expr 2419200 + 1274003127 1276422327

You can now convert that number of seconds from UNIX epoch into a more meaningful current time presentation. You can use different tools, but for this demonstration you'll use gawk with the strftime function: # gawk 'BEGIN {print strftime("%c",'1276422327')}' Sun Jun 13 10:45:27 BST 2010

The above calculation gives the time of the next expiry. So, you now know that spoll's was last changed on ( from the pwd command):

# gawk 'BEGIN {print strftime("%c",'1274003127')}' Sun May 16 10:45:27 BST 2010

And that it will expire on: Sun Jun 13 10:45:27 BST 2010

Answers generally require more explanation than a mere command name. Please elaborate, or move this to a comment. – jw013 Nov 14 '12 at 14:25 I would add to this answer, but I can't find the man page anywhere. Mentioning what flags to give it and what the output will look like would be helpful – Michael Mrozek ♦ Nov 14 '12 at 15:22
