Full Discussion: remote ufsdump permissions
Top Forums UNIX for Advanced & Expert Users remote ufsdump permissions Post 302076322 by jabberwocky on Monday 12th of June 2006 05:53:26 AM

I checked the permissions on the device files:

bash-2.05# rsh bmsapp01 ls -lt /dev/rmt/0cbn
lrwxrwxrwx 1 root other 45 May 31 2005 /dev/rmt/0cbn -> ../../devices/pci@1c,600000/scsi@1/st@5,0:cbn
bash-2.05# rsh bmsapp01 ls -lt /devices/pci@1c,600000/scsi@1/st@5,0:cbn
crw------- 1 root sys 33,221 Jun 10 03:21 /devices/pci@1c,600000/scsi@1/st@5,0:cbn

I changed the permisssions on /devices/pci@1c,600000/scsi@1/st@5,0:cbn on the application server to:

bash-2.05# rsh bmsapp01 ls -lt /devices/pci@1c,600000/scsi@1/st@5,0:cbn
crwxrwxrwx 1 root sys 33,221 Jun 10 03:21 /devices/pci@1c,600000/scsi@1/st@5,0:cbn

However it is still not possible to get a remote ufsdump working by using either method:

bash-2.05# ufsdump 0fuc bmsapp01:/dev/rmt/0cbn /
DUMP: Date of this level 0 dump: Mon 12 Jun 2006 10:52:43 AM BST
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/md/rdsk/d10 (bmsdb01:/) to bmsapp01:/dev/rmt/0cbn.
DUMP: Mapping (Pass I) [regular files]
DUMP: Mapping (Pass II) [directories]
DUMP: Writing 63 Kilobyte records
DUMP: Estimated 10872978 blocks (5309.07MB).
DUMP: /dev/rmt/0cbn: Permission denied
DUMP: NEEDS ATTENTION: Cannot open `bmsapp01:/dev/rmt/0cbn'. Do you want to retry the open?: ("yes" or "no") yes
DUMP: /dev/rmt/0cbn: Permission denied
DUMP: NEEDS ATTENTION: Cannot open `bmsapp01:/dev/rmt/0cbn'. Do you want to retry the open?: ("yes" or "no") no
DUMP: The ENTIRE dump is aborted.

or:

bash-2.05# ufsdump 0fuc - / | rsh bmsapp01 dd of=/dev/rmt/0cbn
DUMP: Date of this level 0 dump: Mon 12 Jun 2006 10:55:26 AM BST

DUMP: Writing 63 Kilobyte records
DUMP: Estimated 10872978 blocks (5309.07MB).
DUMP: Dumping (Pass III) [directories]

Thanks,

lwp-dump

LWP-DUMP(1)						User Contributed Perl Documentation					       LWP-DUMP(1)

NAME

       lwp-dump - See what headers and content is returned for a URL

SYNOPSIS

       lwp-dump [ options ] URL

DESCRIPTION

       The lwp-dump program will get the resource indentified by the URL and then dump the response object to STDOUT.  This will display the
       headers returned and the initial part of the content, escaped so that it's safe to display even binary content.	The escapes syntax used is
       the same as for Perl's double quoted strings.  If there is no content the string "(no content)" is shown in its place.

       The following options are recognized:

       --agent str
	   Override the user agent string passed to the server.

       --keep-client-headers
	   LWP internally generate various "Client-*" headers that are stripped by lwp-dump in order to show the headers exactly as the server
	   provided them.  This option will suppress this.

       --max-length n
	   How much of the content to show.  The default is 512.  Set this to 0 for unlimited.

	   If the content is longer then the string is chopped at the limit and the string "...
(### more bytes not shown)" appended.

       --method str
	   Use the given method for the request instead of the default "GET".

       --parse-head
	   By default lwp-dump will not try to initialize headers by looking at the head section of HTML documents.  This option enables this.
	   This corresponds to "parse_head" in LWP::UserAgent.

       --request
	   Also dump the request sent.
