telnetd /dev/pts/ta

[Trevor Stone]

Hi,
I am running a HPUX 11.x on s B180L and the problem I am running into is I can't telnet from a remote box to this B180L box, as it seems like devices ta and soem other are missing under /dev/pts. I was looking into making those device(s) but before that I wanted to see some more suggestions. I am up-to-date on my patch level.

Please forward any suggestions.

Hi,

You can recreate any missing or corrupt device files with insf. For you case,

insf -eC pseudo

will give you what you need. If it is just the pts files,

insf -ed pts

will install the files for the pts driver. See the man page for insf for more information.

Mujeeb,
At 11.0, I've seen this problem most often after a customer has upgraded the telnetd patch. There are certain patch interdependencies that need to be satisified, including updating the insf patch PHCO_17090 (or later). Also the telnet streams PTY devices naming convention is different at 11.0, and changed again after the recent versions of the telnetd patch. The telnetd patch special instructions contain this information, along with this:
NOTE:
For getting more user logins, the kernel configuration parameter 'nstrtel' needs to be modified to the desired number and rebuild the kernel. Ensure that the extra telnet pseudo ttys are created by doing 'insf -d tels'.
You didn't indicate which telnetd patch was installed, but I read the above from the PHNE_21822.text file.
I hope this additional information helps you resolve the issue.
