sackd(8) Slurm Auth and Cred Kiosk Daemon sackd(8) NAME sackd - Slurm Auth and Cred Kiosk Daemon. SYNOPSIS sackd [OPTIONS...] DESCRIPTION sackd is the Slurm Auth and Cred Kiosk Daemon. It can be used on login nodes that are not running slurmd daemons to allow authentication to the cluster. The program will run as the SlurmUser. When running in Slurm's "configless" mode, in which case configuration files are retrieved and written under the /run/slurm/conf directory (unless RUNTIME_DIRECTORY is set). OPTIONS --ca-cert-file <file> Absolute path to CA certificate used for fetching configuration when running configless in a TLS enabled cluster. --conf-server host[:port] Retrieve configs from slurmctld running at host[:port]. Requires slurmctld support provided by setting enable_configless in Slurm- ctldParameters. -D Run sackd in the foreground with logging copied to stderr. --disable-reconfig Fetch configurations in configless mode once, but do not register with slurmctld for further reconfiguration updates. -f config Read configuration from the specified file. -h Help; print a brief summary of command options. --jwks-file <file> Read auth/slurm JWKS information from the specified file. Default value is slurm.jwks located in the same directory as slurm.conf. --key-file <file> Read auth/slurm authentication key from the specified file. Default value is slurm.key located in the same directory as slurm.conf. --port number Port socket number to listen for reconfiguration updates. This can be useful when multiple sackds co-exist on the same login node. The default value is SlurmdPort. --systemd To be used when started from a systemd unit file. -v Verbose mode. Multiple -v's increase verbosity. ENVIRONMENT VARIABLES The following environment variables can be used to override settings com- piled into sackd. ABORT_ON_FATAL When a fatal error is detected, use abort() instead of exit() to terminate the process. This allows backtraces to be captured without recompiling Slurm. RUNTIME_DIRECTORY Absolute path governing the location for both the configuration cache sackd maintains, and the sack.socket unix socket used to pro- vide authentication services. If multiple sackds need to be started on the same login node, the RuntimeDirectory systemd unit option should be set to slurm-<clus- tername>. Systemd v240+ automatically sets RUNTIME_DIRECTORY to /run/$RuntimeDirectory for each sackd service, otherwise it requires manual setting (i.e. via EnvironmentFile unit option). If this is not set, the default value is /run/slurm/. SACKD_DEBUG Set debug level explicitly for syslog and stderr. Valid values are 0-9, or the same string values as the debug options such as Slurm- ctldDebug in slurm.conf(5). SACKD_DISABLE_RECONFIG Same as --disable-reconfig. SACKD_PORT Same as --port. SACKD_STDERR_DEBUG Set debug level explicitly for stderr. Valid values are 0-9, or the same string values as the debug options such as SlurmctldDebug in slurm.conf(5). SACKD_SYSLOG_DEBUG Set debug level explicitly for syslog. Valid values are 0-9, or the same string values as the debug options such as SlurmctldDebug in slurm.conf(5). SLURM_CONF The location of the Slurm configuration file. SLURM_DEBUG_FLAGS Specify debug flags for sackd to use. See DebugFlags in the slurm.conf(5) man page for a full list of flags. The environment variable takes precedence over the setting in the slurm.conf. SIGNALS SIGINT sackd will shutdown cleanly. SIGHUP sackd will reconfigure. SIGUSR2 SIGPIPE This signal is explicitly ignored. COPYING Copyright (C) SchedMD LLC. This file is part of Slurm, a resource management program. For details, see <https://slurm.schedmd.com/>.
