NAME

       make_sha1 - Generate SHA1 checksums for given set of users.

SYNOPSIS

       make_sha1 [ -C config-file ] [ -D md5_dir ] [ -k count ] [ -f input_file ] [ -m offset ] [ -M modulo ] [ -v ] [ userid...  ]

DESCRIPTION

       Generate  SHA1  checksums  for  messages  given	set  of  users.  Works as incremental update: reads in existing set of SHA1 checksums from
       sha1_dir/u/userid (hashed on first letter of userid) if that file exists. Scans account looking for new messages, and then updates record.

       The SHA1 checksums which are generated are used to test integrity of the master, replica and backup systems on Hermes.

OPTIONS

       -C config-file
	      Read configuration options from config-file.

       -D sha1_dir
	      Read and write SHA1 checksums from sha1_dir, overrides configuration file setting of the same name.

       -k count
	      Concurrency level: run up to count asynchronous child processes.

       -f input_file
	      List of accounts to process: use in place of command line arguments.

       -m offset
	      Regenerate given fraction of the user database in combination with -M below.

       -M modulo
	      Regenerate SHA1 checksums for given fraction of user database. Allows for rolling consisency checks.

       -v     Verbose mode.

NAME

       rdd-verify - verifies checksums and hash values generated by rdd-copy(1)

SYNOPSIS

       rdd-verify [OPTION] file1 ...

DESCRIPTION

       Rdd-verify  verifies  checksums	and  hash values generated by rdd-copy(1).  Rdd stores checksums (Adler32 or CRC32) in files.  These files
       must be passed to rdd-verify for verification.

       Hash values (MD5 or SHA1) computed by rdd-copy(1) must be passed to rdd-verify on the command line as hexadecimal strings.

       Rdd-verify reads all input files (file1, ...) and recomputes the checksums and hash values that the user wishes to verify.   The  verifica-
       tion will very likely fail if the concatenation of the input files is different from the source that was copied by rdd-copy(1).

OUTPUT

       All verification errors are reported on stderr.

OPTIONS

       -?, --help
	      Print a usage message.

       -V, --version
	      Report version number and exit.

       -v, --verbose
	      Be verbose (more messages).

       -v, --verbose
	      Be verbose (more messages).

       --checksum, --adler32 file
	      Verify the Adler32 checksums stored in file.

       --crc, --crc32 file
	      Verify the CRC32 checksums stored in file.

       --md5, --md5 digest
	      Recompute the MD5 hash value.  It should be equal to digest.

       --sha, --sha1 digest
	      Recompute the SHA1 hash value.  It should be equal to digest.

       A digest argument is a hexadecimal string.  Leading zeroes may not be omitted.

EXAMPLES

       rdd-verify --md5 0123456789abcdef0123456789abcdef disk.img

	      Compute the MD5 hash value over disk.img and verify whether it equals 0123456789abcdef0123456789abcdef.

       rdd-verify --adler32 checksums.a32 disk.img

	      Compute the adler32 checksums over disk.img and compare each checksum to the corresponding checksum in checksums.a32.
