server blocked when using distcc

[JCX]

Hi all,

I compile code using distcc in two eight core machines. In the server
machine, i use the command "distccd --daemon --allow 10.1.4.0/22" and
see the distccd process when i use "ps -ax | grep distccd". In the
host machine, i set the environment variable DISTCC_HOSTS="localhost/8
pek-office/8". However, when i use the "distccmon-text 2" to see the
compile process, i got the result:

 22723  Connect     pngpread.c                     pek-office[0]
 22747  Connect     pngrio.c                         pek-office[1]
 22763  Connect     pngrutil.c                        pek-office[2]
  4304  Compile     RenderTableSection.cpp   localhost[0]
 27914  Compile     pvmf_protocol_engine_common.cp                localhost[1]
  4291  Compile     RenderTableRow.cpp        localhost[2]

 22723  Blocked     pngpread.c                     pek-office[0]
 22763  Blocked     pngrutil.c                        pek-office[2]

It seems all the files are compiled on localhost. pek-office server is
in either "connect" or "blocked" status.

So, can someone explain what could be happening here? What can i do to
sort this problem out?

Thanks for your help.

Have a look in the server's log file.

I use the command "distccd --log-file /tmp/distccd.log --daemon
--allow 10.1.4.0/22". And the distccd.log is:

I don't know why this error happens. Can you give me some suggestions?

Thanks,

Because the address is already in use. :-)

Use 'netstat -tlp' to see what process is listening on that port.
Maybe inetd is also trying to serve distcc?

Use 'netstat -tlp' to see what process is listening on that port.

Or maybe you have another distccd server running (perhaps stopped).
Try "killall -9 distccd".

Thanks for your help.

I use "netstat -tlp" command. The following is the result:

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address      Foreign Address   State
PID/Program name
tcp        0      0           *:41990                 *:*

      LISTEN      13521/cupsd

tcp6       0      0          [::]:ssh                  [::]:*
        LISTEN      6264/sshd


I don't know which process is listening to the same port. What's more,
I use "killall -9 distccd" and then "distccd --log-file
/tmp/distccd.log --daemon
--allow 10.1.4.0/22" command. However, the server is still blocked.

Do you have any suggestions?

Thanks very much,
Caixia

I'm guessing that means that process number 7854 ("distccd") is the one using the "distcc" port (port 3623).

That process may be running as root, or as the "distcc" user, in which case you would need to use "sudo killall distccd" or "sudo kill 7854" to kill it.  (Try again with "-9" if that doesn't work.)
