[BackupPC-users] Solaris backuppc_dump and tarclient process dont communicate

[Christophe J. <chr...@cn...>]

Hello

On solaris 2.7 I use backuppc to backup a linux client via rsh.
The backup seems to begin quite well:
    - the tar command is launched on the client
    - The log file tells me that a full dump has begun
But nothing happens: though all processes stay alive , no network traffic
occurs.
i tried to trace the backuppc_dump command code and it seems that the tool keeps

stuck on a select system call:

...
    print("started $type dump, pid=$xferPid, tarPid=$tarPid\n");

    #
    # Parse the output of the transfer program and BackupPC_tarExtract
    # while they run.  Since we are reading from two or more children
    # we use a select.
    #
    my($FDread, $tarOut, $mesg);
    vec($FDread, fileno(TAR), 1) = 1;
    $xfer->setSelectMask(\$FDread);

    SCAN: while ( 1 ) {
        my $ein = $FDread;
        last if ( $FDread =~ /^\0*$/ );
#Everything gets well until here
        select(my $rout = $FDread, undef, $ein, undef);  ## seems not to return
        if ( vec($rout, fileno(TAR), 1) ) {
            if ( sysread(TAR, $mesg, 8192) <= 0 ) {
                vec($FDread, fileno(TAR), 1) = 0;
                close(TAR);
            } else {
                $tarOut .= $mesg;
            }
        }

Anyone can help?...
Thanks
