I have a Solaris 8 Ultra 1 on my network that we use as a utility server.
The last command, which looks in the /var/adm/wtmpx file, is not working.
When I do a last, the latest entry is dated June 3, but the /var/adm/wtmpx file is dated whenever a login is successful (verified by typing a ls -al in the /var/adm directory).
I've rebooted the server, thinking that a process/daemon was hung, but no luck.
Any thoughts? Suggestions?
Many thanks for your support. 
Does:
last -f /var/adm/wtmpx
produce the output you are looking for? Also check permissions on /var/adm/wtmpx. Should be owner and group 'adm' and be 644 permissions
I get the same result as if I had typed the last command.
The last -f /var/adm/wtmpx command returns the last date as June 3.
The permissions and owner/group are as you indicated.
The size of the wtmpx file is 1736260kb and that the time stamp does change when someone logs onto the server.
Ok a few things to check.
is the /var partition full?
df -k /var
Will tell you. Whats the final line of output from your last command ... should read something like:
wtmp begins Wed May 19 14:41
if you do
last reboot
Does it show the previous reboots correctly?
And just to be 100% sure ... Please be aware that 'last' displays the entries in revers order ... ie the most recent entries appear first. So if you run
last | more
The most recent login with be the first line on the first page.
