SYNOPSIS

11       remunge [OPTION]...
12
13

DESCRIPTION

15       The  remunge  program benchmarks the performance of MUNGE.  A benchmark
16       runs for the specified duration or until the specified number  of  cre‐
17       dentials  are processed, whichever comes first.  At its conclusion, the
18       number of credentials processed per second is written to stdout.
19
20       By default, credentials are encoded  for  one  second  using  a  single
21       thread.

OPTIONS

25       -h, --help
26              Display a summary of the command-line options.
27
28       -L, --license
29              Display license information.
30
31       -V, --version
32              Display version information.
33
34       -c, --cipher string
35              Specify the cipher type, either by name or number.
36
37       -C, --list-ciphers
38              Display a list of supported cipher types.
39
40       -m, --mac string
41              Specify the MAC type, either by name or number.
42
43       -M, --list-macs
44              Display a list of supported MAC types.
45
46       -z, --zip string
47              Specify the compression type, either by name or number.
48
49       -Z, --list-zips
50              Display a list of supported compression types.
51
52       -e, --encode
53              Encode  (but  do  not decode) each credential.  By bypassing the
54              decode operation, the credential is not  stored  in  the  replay
55              cache.
56
57       -d, --decode
58              Encode and decode each credential.
59
60       -l, --length integer
61              Specify an arbitrary payload length (in bytes).  The integer may
62              be  followed  by  a  single-character   modifier:   k=kilobytes,
63              m=megabytes, g=gigabytes; K=kibibytes, M=mebibytes, G=gibibytes.
64
65       -u, --restrict-uid uid
66              Specify  the  user name or UID allowed to decode the credential.
67              This will be matched  against  the  effective  user  ID  of  the
68              process requesting the credential decode.
69
70       -g, --restrict-gid gid
71              Specify  the group name or GID allowed to decode the credential.
72              This will be matched against  the  effective  group  ID  of  the
73              process  requesting  the credential decode, as well as each sup‐
74              plementary group of which the effective user ID of that  process
75              is a member.
76
77       -t, --ttl integer
78              Specify  the  time-to-live (in seconds).  This controls how long
79              the credential is valid once it has been encoded.  A value of  0
80              selects  the  default  TTL.   A  value of -1 selects the maximum
81              allowed TTL.
82
83       -S, --socket path
84              Specify the local domain socket for connecting with munged.
85
86       -D, --duration integer
87              Specify the test duration (in seconds).  The default duration is
88              one  second.   A  value of -1 selects the maximum duration.  The
89              integer may be followed by a single-character  modifier:  s=sec‐
90              onds, m=minutes, h=hours, d=days.
91
92       -N, --num-creds integer
93              Specify  the number of credentials to generate.  The integer may
94              be  followed  by  a  single-character   modifier:   k=kilobytes,
95              m=megabytes, g=gigabytes; K=kibibytes, M=mebibytes, G=gibibytes.
96
97       -T, --num-threads integer
98              Specify  the  number  of threads to spawn for processing creden‐
99              tials.
100
101       -W, --warn-time integer
102              Specify the maximum number of  seconds  to  allow  for  a  given
103              munge_encode()  or  munge_decode()  operation  before  issuing a
104              warning.

106

EXIT STATUS

108       The remunge program returns a zero exit  code  if  the  benchmark  com‐
109       pletes.   On  error, it prints an error message to stderr and returns a
110       non-zero exit code.
