You must help 'caput' (all Channel Access clients) to find the specified process variables. Channel Access uses a well defined set of environment variables to configure the method used to locate PVs on a network. One of them is $EPICS_CA_ADDR_LIST, which is used to define a comma-sprated list of IP addresses of hosts that may be running an EPICS IOC holding the PV(s) of interest. It sounds like you are running the caput CA client on the same host as the IOC, so the value "localhost" may be good enough. Before running your CA clients from a bash shell session:

export EPICS_CA_ADDR_LIST="localhost"

If the IOC and CA client are on different hosts, you would use the setting:

export EPICS_CA_ADDR_LIST="the.ioc.host.ip"

where 'the.ioc.host.ip' is in either DNS name format or dotted decimal IP address format.

This assumes that you are using the EPICS CA TCP/IP ports that were configured as defaults when EPICS base was built. Both the IOC and CA clients will default to the same, compatible ports unless modified by setting $EPICS_CA_REPEATER_PORT &/or $EPICS_CA_SERVER_PORT.

I have made a small program. CTRL-FOOO:input is a variable. When I am
compiling and running IOCs, the IOC are running. But when i am writing

*Channel connect timed out: 'CTRL-FOOO:input' not found*

Please can I get some solution to it

thanks in advance
