This is the command ib_acme that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
ib_acme - test and configuration utility for the IB ACM
ib_acme [-f addr_format] [-s src_addr] -d dest_addr [-v] [-c] [-P] [-S svc_addr] [-C repetitions]
ib_acme [-A [addr_file]] [-O [opt_file]] [-D dest_dir] [-V]
ib_acme provides assistance configuring and testing the ibacm service. The first usage of
the service will test that the ibacm is running and operating correctly. The second usage
model will automatically create address and configuration files for the ibacm service.
Specifies the format of the src_addr and dest_addr parameters. Valid address
formats are: 'i' ip address, 'n' host name, 'l' lid, 'g' gid, and 'u' unspecified.
If the -f option is omitted, an unspecified address format is assumed. ib_acme
will use getaddrinfo or other mechanisms to determine which format the address
Specifies the local source address of the path to resolve. The source address can
be an IP address, system network name, or LID, as indicated by the addr_format
Specifies the destination address of the path to resolve. The destination address
can be an IP address, system network name, or LID, as indicated by the addr_format
-v Indicates that the resolved path information should be verified with the active IB
SA. Use of the -v option provides a sanity check that resolved path information is
usable given the current cluster configuration.
-c Instructs the ACM service to only returned information that currently resides in
its local cache.
-P Queries performance data from the destination service
address of ACM service, default: local service
number of repetitions to perform resolution. Used to measure performance of ACM
cache lookups. Defaults to 1.
With this option, the ib_acme utility automatically generates the address
configuration file ibacm_addr.cfg. The generated file is constructed using the
system host name.
With this option, the ib_acme utility automatically generates the option
configuration file ibacm_opts.cfg. The generated file is currently generated using
Specify the destination directory for the output files.
-V Enables verbose output. When combined with -A or -O options, ib_acme will display
additional details, such as generated address information saved to the
The ib_acme utility performs two main functions. With the -A and -O options, it
automatically generates address or options configuration files. The generated files are
text based and may be edited. These options are intended to provide a simple way to
configure address and option information on all nodes on a cluster.
The other function of the ib_acme utility is to test the ibacm service, including helping
to verify that the service is usable given the current cluster configuration. The ib_acme
utility can resolve IP addresses, network names, or IB LIDs into a path record. It can
then compare that path record against one obtained by the SA. When used to test the ibacm
service, the ib_acme utility has the side effect of loading the ibacm caches.
Multiple, numerical destinations can be specified by adding brackets  to the end of a
base destination name or address. Users may specify a list of numerical ranges inside the
brackets using the following example as a guide: node[1-3,5,7-8]. This will result in
testing node1, node2, node3, node5, node7, and node8.
