is "inetd telnet slowness" fixed?


I just did a fresh install of 1.3.17 and setup telnetd. The login prompt
is delayed by about 3 minutes!  rlogin works just fine.

This problem was described in detail
in the mailing list towards the end of the summer.

Is there a fix or a workaround?

thanks/regards,
Tom Rodman

I wrote about a month ago with this problem,  but didn't manage to work out
a viable solution.

If I stop inetd and run "in.telnetd -debug"  All is well.  It appears to
capture the machine/user correctly and  I am imediately logged in (bypassing
the login/passwd prompt).

With inetd running, telnet starts,  then hangs for about 3 minutes,  finaly
ginving me a "Login:" prompt.  I assume that Inetd didn't pass usable
machine/user information to the in.telnetd,  and that the delay and eventual
"login:" prompt is in.telnetd  timing out waiting for  login information,
but I could be wrong about this.  Rlogind works fine with inetd,  and I
assume it uses a similar validation mechanism.   I'd appreciate any
assistance.


The diff of the Debug logs with and without inetd:

Thanks for the quick response.


Those particular machines (1.3.12) are all on different segments from each
other,  with different os's (NT,XP, and 2K). But I have tried from other
machines on both the same and different segments,  same result,  and from
different telnet clients (SGI,  Linux, NT, Cygwin...)  it seems consistant.
I even telneted to "localhost" and to the machine name and ip from
itself....  same result.  I assume reverse DNS is configured as it works (I
didn't know it was configurable)..   as a side note,  rsh/rlogin works like
a champ....
