When a HPUX system that we have reaches 60 users, no more people can
telnet. The guy administering the system changed some kernal
parameters, and it just changes the message that we get. Now the
message says   "telnetd:  /dev/pts/t9  no such file or directory"

Does this mean that we don't have enough pseudo terminal device files?
Do I need to run insf to create the missing files? If so, could I
screw things up by running this? Thanks in advance.

Yes. Run

# insf -v -e -s <required_num_of pts>

excerpt from insf(1M).

~~
  -s nstrpty     Install nstrpty slave-side stream special files
                 for the pts driver.  nstrpty is a decimal number.
                 This option only applies to the pts special file
                 installation.

                 This option is effective only if the -e option is
                 specified or if an appropriate device class or
                 driver is specified with a -C or -d option.

                 If this option is omitted, nstrpty defaults to 60.

Thank you very much. It solved my problem. Any recommendations on a
good book(s) or website(s) that cover how different parts of the OS
work? I work more at the Database and Application level, but I'm going
to need to know more about Unix, configuring the OS, etc. I've got
enough knowledge to be dangerous, and would like to become less
dangerous. I'll probably look towards getting two books, one that is
basic. Sort of like a Dummy's book. And then another that goes into
depth on things.
