| Information About This Lsof Distribution
|What You Have
|If you got this far without being confused, then you are probably
|familiar with the construction of the lsof distribution or you have
|read RELEASE.SUMMARY_4.85. If either is the case, please skip to
|the Inventory section. If you haven't read RELEASE.SUMMARY_4.85,
|I suggest you do it now, because it explains how the lsof distribution
|is constructed and other useful things about lsof, including a
|summary of changes for the past few lsof revisions.
|Even though you may have thought you were getting lsof.tar.bz2,
|lsof.tar.gz or lsof.tar.Z with ftp, you really got lsof_4.85.tar.bz2,
|lsof_4.85.tar.gz or lsof_4.85.tar.Z. That's because the triplet of
|lsof.tar.* files are symbolic links to their longer-named counterparts.
|The bzip2'd, gzip'd or compressed tar files with lsof_, followed by a
|number, are wrapper archives, designed to package the lsof source
|archive, this file, other documentation files, and a GPG authentication
|The number, 4.85, is the lsof revision number. When you bunzip2'd,
|gunzip'd or uncompressed lsof_4.85.tar.* and used tar to unpack
|lsof_4.85.tar, you got: 00.README.FIRST_4.85, describing the contents
|of lsof_4.85; README.lsof_4.85; lsof_4.85_src.tar; and
|lsof_4.85_src.tar.sig. All are identified with the revision number.
|You're reading README.lsof_4.85. lsof_4.85_src.tar.sig is a GPG
|certificate that authenticates the lsof source archive,
|After you read the Inventory and Security sections, and hopefully
|after you check the GPG certificate, unpack the lsof_4.85_src.tar
|source archive and you will get a sub-directory, named lsof_4.85_src,
|that contains the lsof 4.85 source distribution.
|Once you have unpacked lsof_4.85_src.tar.tar, you can check
|lsof_4.85_src for completeness by changing to that sub-directory
|and running the Inventory script. The lsof_4.85_src/Configure
|script runs the Inventory script, too. The Configure script also
|calls a customization script, called Customize. You can direct
|Configure to avoid calling Inventory and Customize with the -n
|See the Distribution Contents section of the 00DIST file and The
|Inventory Script section of the 00README file for more information
|on the contents of the lsof distribution, and the Configure,
|Customize and Inventory scripts. The 00DIST and 00README files
|will be found in the lsof_4.85_src sub-directory you just created.
|The md5 checksum for lsof_4.85_src.tar is:
| MD5 (lsof_4.85_src.tar) = 93d972459bbae304951b438d63e03e64
|A good source for an MD5 checksum computation tool is the OpenSSL
|project whose work may be found at:
|You can use the openssl "dgst" operator to compute an MD5 checksum --
| $ openssl dgst -md5 lsof_4.85_src
|The old-style sum(1) checksum for lsof_4.85_src.tar (Please read
|the next paragraph if you don't get this value.) is:
| 62553 8391 lsof_4.85/lsof_4.85_src.tar
|If your dialect's sum(1) program defaults to the new style algorithm
|(e.g., Solaris), you may have to use its -r option (or use the
|Solaris /usr/ucb/sum). If your Unix dialect doesn't have a sum(1)
|program (e.g., FreeBSD, or NetBSD), use its cksum(1) program with
|the -o1 option to get an old-style checksum. You may also need to
|ignore the block count, depending on the block size used on your
|your system (i.e., 512 or 1,024). The sum(1) that produced the
|above checksum considers block size to be 512; in contrast the BSD
|cksum(1) programs' -o1 option considers block size to be 1,024.
|lsof_4.85_src.tar.sig is a GPG certificate file, using my public
|key. My key may be available on some public key servers under the
| Victor A. Abell <email@example.com>
| Victor A. Abell <firstname.lastname@example.org>
|You will also find it at:
|Get my key and install it in your public key ring.
|Once my key is installed, use this command to check the certificate
| gpg --verify lsof_4.85_src.tar.sig lsof_4.85_src.tar
|If the certificate check isn't good, lsof_4.85_src.tar is suspect.
|Report the problem to me via e-mail at <email@example.com>.
|If you don't have GPG, you can compare the md5 checksum of
|lsof_4.85_src.tar to the value listed in this file. However, that
|is a less reliable authentication method, since it can't detect
|changes to both lsof_4.85_src.tar and the md5 checksum value listed
|in this tile.
|Signature information for the distribution file that contains
|this file may be found in the CHECKSUMS file that is located
|where the distribution file was found.
