[mpich-discuss] handle_mpd_output 393

[吴长江]

  HI:
    I install MPICH2 under my ubuntu OS.And I have three computers.


In computer one (node0), /etc/hosts file is :
127.0.0.1       localhost.localdomain   localhost
::1     wcj     localhost6.localdomain6 localhost6
127.0.1.1       ubuntu.ubuntu-domain    wcj

# The following lines are desirable for IPv6 capable hosts
#::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

192.168.1.100 node0 server
192.168.1.122 node1 qym
192.168.1.115 node2 npp

and I use mpdcheck to test whether node0 is ok.Output ,after mpdcheck is
that :
*** the fq hostname seems to be localhost

    **********
    Your fully qualified and unqualified names do not resolve to
    the same IP. This likely means that your DNS domain name is not
    set correctly.  This might be fixed by adding a line similar
    to the following to your /etc/hosts:
 $ipaddr     $fqhn   $uqdn
    **********


In computer two (node1),/etc/hosts file is :
#::1     ubuntu  localhost6.localdomain6 localhost6
127.0.1.1       ubuntu.ubuntu-domain    ubuntu
127.0.0.1       localhost.localdomain   localhost
           
# The following lines are desirable for IPv6 capable hosts
#::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
    
192.168.1.100 wcj    node0
And ,after mpdcheck ,output is :
*** first ipaddr for this host (via ubuntu) is: 127.0.1.1

Computer three (node2) has the same problem as node1.

Meanwhile ,after mpdboot -n 3 -f mpd.hosts,output is :
/mirror/mpich2/bin/mpdboot:56: DeprecationWarning: The popen2 module is
deprecated.  Use the subprocess module.
  from popen2   import Popen4, Popen3, popen2
/mirror/mpich2/bin/mpdlib.py:15: DeprecationWarning: the md5 module is
deprecated; use hashlib instead
  from  md5       import  new as md5new
mpdboot_wcj (handle_mpd_output 393): failed to handshake with mpd on
node2; recvd output={}

  Those are the three problems which I meet,and
I don't know how to correct the problems.

Thank you !
