makedumpfile-1.1.0: SSH Transporting support

[oomichi at mxs.nes.nec.co.jp (Ken'ichi Ohmichi)]

Hi.

makedumpfile version 1.1.0 is released.
Please test it. Your opinions/comments are welcome.

Explanation of makedumpfile:
  To shorten the size of the dumpfile and the time of creating the
  dumpfile, makedumpfile copies only the necessary pages for analysis
  to the dumpfile from /proc/vmcore. You can specify the kind of
  unnecessary pages with dump_level. If you want to shorten the size
  further, enable the compression of the page data.

Changelog:
- SSH transporting support
  For ssh transporting support, -F and -R options are added.
  A panic system sends dump data to a remote host with -F option, and
  a remote host re-arranges dump data received to a normal dumpfile
  (readable by analysis tools) with -R option.
  Example-1:
  # makedumpfile -F -cd31 -x vmlinux /proc/vmcore | ssh user at host "makedumpfile -R dumpfile"

  A perl script makedumpfile-R.pl implements the same function as '-R'
  option. Perl script does not depend on architecture, and a lot of
  systems have perl command. Even if a remote host does not have the
  makedumpfile command, it is possible to transport a dumpfile to a
  remote host with running this script.
  Example-2:
  1. Transport the script.
    # scp makedumpfile-R.pl user at remote:makedumpfile-R.pl
  2. Transport a dumpfile. 
    # makedumpfile -F -cd31 -i config /proc/vmcore | ssh user at remote "./makedumpfile-R.pl dumpfile"

You can download the latest makedumpfile(ver. 1.1.0) from the following URL.
Details of the change are written on the CVS page of the following site.
https://sourceforge.net/projects/makedumpfile/


Method of installation:
  You can compile the makedumpfile command as follows;
  1. "tar -zxvf makedumpfile-1.1.0.tar.gz"
  2. "cd makedumpfile"
  3. "make; make install"

Usage:
  makedumpfile [-c] [-E] [-d dump_level] [-x vmlinux] dump_mem dump_file

Example:
  If you want to exclude pages filled by zero, cache pages, user pages
  and free pages and to enable compression, please execute the following
  command.

  # makedumpfile -c -d 31 -x vmlinux /proc/vmcore dumpfile

Todo:
  - Dumping DISCONTIGMEM kernel
