[comp.sys.ibm.pc.rt] RT/AIX network problems

psiders@umn-d-ub.D.UMN.EDU (Paul Siders) (03/26/90)

Thanks to all who offered help for my problem installing VRM 2.2.1 .
I tried responding to several of you individually, but I don't know if
my mail reached you.

  [  moody@moody..austin.ibm.com                              ]
I used James Moody's instructions, as follows (THANKS!):
    Boot the machine.  Hit ctl-alt-numpad4 (only works if you have
    some display connected to the RT that is not the megapel).
    You are now in the VRM debugger.  At the prompt, do the following:
       >al F0008828 F0 [enter]
       >g [enter]
    You should be back in AIX now.  Shutdown and reboot from diskette.
        -------------------------------------------------- 

Now that I have AIX 2.2.1 installed, I am having trouble reaching the
network.  I have an ethernet connection to a local (U of Minn - Duluth)
network.  My RT's internet address is 131.212.32.10 .  I can telnet and ftp
out to the local network, but not to off-campus sites (e.g., not to
128.101.16.3    sc.msc.umn.edu ).  I do receive mail on the RT from campus
machines, but apparently not from off-campus machines.  (The mail address
I've given below is on another campus computer.)  I cannot telnet 
into the RT ("rtchem.d.umn.edu") from even the campus network.  I can't 
start telnetd - error message is below.  I have an old (1986) tcp/ip manual,
but didn't find much helpful in it.  I have asked my local IBM office to 
order a new tcpip manual for me, but that's likely to take a few months.  
I would appreciate suggestions.

Below are three commands that ran when I had AIX 2.2 installed, but 
now fail.  I am using the old /etc/hosts file. 

 I enter:/usr/lpp/tcpip/etc/telnetd &
response:/usr/lpp/tcpip/etc/telnetd: getpeername: No such device

 I enter:route add 128.0.0.0 ags 1
response:add net 128.0.0.0: gateway : Network is unreachable
  
 I enter:telnet   (or telnet -e vt100)   (Of course, it was "tn" in AIX2.2)
response:Can't emulate a 3270 terminal on a vt100 terminal
response:                                                 telnet>
Then the terminal stops echoing characters and the rt stops responding to
things I type, except that ^c does get me a new prompt.  Note: I have set
EMULATE=vt100 .

Ideas?  What does the "getpeername" message refer to?  I have tried what 
I found in chapters 7 and 8 of the "Managing the AIX Op Sys" manual.  I also
looked around in /usr/lpp/tcpip/samples and tried customizing named.boot there:
( domain 10.32.212.131 ) but I didn't know what I was doing with named.boot,
and the resulting named.rev and named.data files don't look good:
   setting default domain to ... "."  .

Thanks for your help.
