lslogin

---

remotely logs in to a lightly loaded host

SYNOPSIS

lslogin [-v] [-m "host_name ..." | -m "cluster_name ..."] [-R "res_req"] [rlogin_options]

lslogin [-h | -V]

DESCRIPTION

Remotely logs in to a lightly loaded host.

By default, lslogin selects the least loaded host, with few users logged in, and remotely logs in to that host using the UNIX rlogin command.

In a MultiCluster environment, the default is to select the least loaded host in the local cluster.

OPTIONS

-v

Displays the name of the host to which lslogin remotely logs you in.

-m "host_name ..." | -m "cluster_name ..."

Remotely logs in to the specified host.

With MultiCluster job forwarding, when a cluster name is specified, remotely logs in to the least loaded host in the specified cluster, if the remote cluster accepts interactive jobs from the local cluster (see lsf.cluster(5)).

-R "res_req"

Remotely logs in to a host that meets the specified resource requirement. The resource requirement expression restricts the set of candidate hosts and determines the host selection policy.

For a complete explanation of resource requirement expressions, see lsfintro(1). To find out what resources are configured in your system, use lsinfo(1) and lshosts(1).

rlogin_options

Specify remote login options passed to the rlogin command.

If remote execution fails, lslogin will log in locally only if the local host also satisfies required resources; otherwise, log in will fail.

-h

Prints command usage to stderr and exits.

-V

Prints LSF release version to stderr and exits.

EXAMPLE

% lslogin -R "select[it>1 && bsd]"

Remotely logs in to a host that has been idle for at least 1 minute, that runs BSD UNIX, and is lightly loaded both in CPU resources and the number of users logged in.

SEE ALSO

lsfintro(1), ls_placereq(3), rlogin(1)

DIAGNOSTICS

Because lslogin passes all unrecognized arguments to rlogin, incorrect options usually cause the rlogin usage message to be displayed rather than the lslogin usage message.
