Hi,
as far as I know below the only three reasons about message
"telnetd: Telnet device drivers missing: No such device".
1. check by
# swlist -l product | grep -i PHNE_25913
# swlist -l product | grep -i PHNE_27393
about patch PHNE_25913 or PHNE_27393; if one of these patches is installed then you could have that message. There are known problems about these patches and that telnet message.
SOLUTION:
remove those patches and install the equivalent patch PHNE_27788 or later.
2. major/minor number of telnet device files are different:
# lsdev | grep tel
18 -1 telm strtelm
19 -1 tels strtels
The value shown by "lsdev" for "telm" would need to be equal to the minor
number of "/dev/telnetm"
- AND -
the value shown for "tels" would need to be equal to the major number of
the /dev/pty/t* device files.
SOLUTION:
To solve the problem, we need to remove the incompatible device files
and create new device files:
a.) For the "tels"-devices:
=> rmsf /dev/pts/t*
=> insf -v -d tels
b.) For the "telm"-device:
=> rmsf /dev/telnetm
=> insf -v -d telm
3. Reached the limit of connections:
SOLUTION:
by SAM increase the following kernel parameters:
maxusers
npty
nstrpty
and after reboot execute the following commands:
# rm /dev/pty/*
# rm /dev/ptym/*
# cd /dev
# insf -d pty -n 400
400 is an example if you incerased npty and nstrpty to 400.
I hope this helps you.
Best regards,
Ettore
WISH? IMPROVEMENT!
