sndrd(1M) System Administration Commands sndrd(1M)NAME
sndrd - Remote Mirror daemon
SYNOPSIS
/usr/lib/sndrd [-c max_connections] [-l listen_backlog]
DESCRIPTION
The sndrd daemon processes client Remote Mirror requests. Only the root user or a user with equivalent privileges can run this daemon. The
daemon is automatically invoked in run level 2. sndrd restarts the TCP transport layers.
Administrators wanting to change startup parameters for sndrd should, as root or equivalent, make changes in the /etc/default/sndr file
rather than editing the /lib/svc/method/svc-rdcsyncd file. See sndr(4).
OPTIONS
The sndrd daemon supports the following options:
-c max_connections
Sets the maximum number of connections allowed to the server over connection-oriented transports. By default, the number of connections
is 16.
-l listen_backlog
Sets connection queue length for the RDC TCP over a connection-oriented transport. The default value is 10 entries.
EXIT STATUS
0 Daemon started successfully.
>0 Daemon failed to start.
Error information is reported to syslog at level LOG_ERR.
FILES
/lib/svc/method/svc-rdcsyncd
Shell script for starting sndrd.
/lib/svc/method/svc-rdc
Shell script for stopping sndrd.

Do not manually stop the sndrd deamon. If you need to manually stop sndrd perform these steps. This stops both the sndrd and sndrsyncd dae-
mons.
# svcadm disable svc:/system/nws_rdc
# svcadm disable svc:/system/nws_rdcsyncd
Do not manually start or restart the sndrd deamon. If you need to manually start sndrd perform these steps. This starts both the sndrd and
sndrsyncd daemons.
# svcadm enable svc:/system/nws_rdc
# svcadm enable svc:/system/nws_rdcsyncd

nfsd - NFS daemon
SYNOPSIS
/usr/lib/nfs/nfsd [-a] [-c #_conn] [-l listen_backlog] [-p protocol] [-t device] [nservers]
nfsd is the daemon that handles client file system requests. Only users with {PRIV_SYS_NFS} and sufficient privileges to write to /var/run
can run this daemon.
The nfsd daemon is automatically invoked using share(1M) with the -a option.
By default, nfsd starts over the TCP and UDP transports for versions 2 and 3. By default, it starts over the TCP for version 4. You can
change this with the -p option.
A previously invoked nfsd daemon started with or without options must be stopped before invoking another nfsd command.
Administrators wanting to change startup parameters for nfsd should, as root, make changes in the /etc/default/nfs file. See nfs(4).
The following options are supported:
-a Start a NFS daemon over all available connectionless and connection-oriented transports, including UDP and TCP. Equivalent
of setting the NFSD_PROTOCOL parameter to ALL in the nfs file.
-c #_conn This sets the maximum number of connections allowed to the NFS server over connection-oriented transports. By default, the
number of connections is unlimited. Equivalent of the NFSD_MAX_CONNECTIONS parameter in the nfs file.
-l Set connection queue length for the NFS TCP over a connection-oriented transport. The default value is 32 entries. Equiva-
lent of the NFSD_LISTEN_BACKLOG parameter in the nfs file.
-p protocol Start a NFS daemon over the specified protocol. Equivalent of the NFSD_PROTOCOL parameter in the nfs file.
-t device Start a NFS daemon for the transport specified by the given device. Equivalent of the NFSD_DEVICE parameter in the nfs
file.
The following operands are supported:
nservers This sets the maximum number of concurrent NFS requests that the server can handle. This concurrency is achieved by up to
nservers threads created as needed in the kernel. nservers should be based on the load expected on this server. 16 is the
usual number of nservers. If nservers is not specified, the maximum number of concurrent NFS requests will default to 1.
Equivalent of the NFSD_SERVERS parameter in the nfs file.
USAGE
If the NFS_PORTMON variable is set in /etc/system, then clients are required to use privileged ports (ports < IPPORT_RESERVED) to get NFS
services. This variable is equal to zero by default. This variable has been moved from the "nfs" module to the "nfssrv" module. To set the
variable, edit the /etc/system file and add this entry:
set nfssrv:nfs_portmon = 1
0 Daemon started successfully.
1 Daemon failed to start.
.nfsXXX Client machine pointer to an open-but-unlinked file.
/etc/default/nfs Contains startup parameters for nfsd.
/etc/system System configuration information file.
/var/nfs/v4_state Directories used by the server to manage client state information. These directories should not be removed.
/var/nfs/v4_oldstate

Manually starting and restarting nfsd is not recommended. If it is necessary to do so, use svcadm to enable or disable the nfs service
(svc:/network/nfs/server). If it is disabled, it will be enabled by share_nfs(1M), unless its application/auto_enable property is set to
false. See the , and svcadm(1M) for more information.
The nfsd service is managed by the service management facility, smf(5), under the service identifier:
svc:/network/nfs/server
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
vice's status can be queried using the svcs(1) command.
If nfsd is killed with SIGTERM, it will not be restarted by the service management facility. Instead, nfsd can be restarted by other sig-
nals, such as SIGINT.
