Operating Systems Linux Red Hat How do I know whether a service is online? Post 302797237 by Sod on Monday 22nd of April 2013 05:59:04 AM

Server services online
There are various methods to confirm this.. My usual way is to check first whether the service is active on the corresponding port with help of telnet.

In the case of web service

HTML Code:
#telnet localhost 80
Or we can use

HTML Code:
#service httpd status
HTML Code:
#pidof httpd
HTML Code:
#ps -e | grep httpd
Always confirm from the Client end also if the service is a critical one.

HTML::FormFu::Constraint::DependOn(3pm) 		User Contributed Perl Documentation		   HTML::FormFu::Constraint::DependOn(3pm)

NAME

       HTML::FormFu::Constraint::DependOn - Multi-field Dependency Constraint

SYNOPSIS

	   type: DependOn
	   name: foo
	   others: bar

DESCRIPTION

       If a value is submitted for the field this constraint is attached to, then a value must also be submitted for all fields named in "others"
       in HTML::FormFu::Constraint::_others.

       By default, if any of the named fields in "others" in HTML::FormFu::Constraint::_others are missing, an error will be attached to each
       missing field. This behaviour can be changed by setting any of "attach_errors_to_base" in HTML::FormFu::Constraint::_others,
       "attach_errors_to_others" in HTML::FormFu::Constraint::_others or "attach_errors_to" in HTML::FormFu::Constraint::_others.

       This constraint doesn't honour the "not()" value.

SEE ALSO

       Is a sub-class of, and inherits methods from HTML::FormFu::Constraint::_others, HTML::FormFu::Constraint

       HTML::FormFu
