Linux isn't Windows. So at least in some cases, while there are ways to get the information, Linux doesn't spray the network constantly with sensitive information like Windows does. In particular, what a host calls itself isn't necessarily easy. At best you can do IP to DNS name correlation, but that's really outside of the host itself.

For the rest, e.g. port scanning and service information...

nmap is your friend.

Also, unlike Windows, service scanning can be slow... which is a security feature. The insecurity of Windows arguably makes it "friendlier" for scanning...

NAME
avahi.service - avahi-daemon static service file SYNOPSIS
/etc/avahi/services/*.service DESCRIPTION
/etc/avahi/services/*.service are XML fragments containing static DNS-SD service data. Every service file can contain multiple service def- initions which share the same name. This is useful for publishing service data for services which implement multiple protocols. (i.e. a printer implementing _ipp._tcp and _printer._tcp) XML TAGS
<service-group> The document tag of avahi service files. Should contain one <name> and one or more <service> elements. <name replace-wildcards="yes|no"> The service name. If replace-wildcards is "yes", any occurence of the string "%h" will be replaced by the local host name. This can be used for service names like "Remote Terminal on %h". If replace-wildcards is not specified, defaults to "no". <service protocol="ipv4|ipv6|any"> Contains the service information for exactly one service type. Should contain one <type> and one <port> element. Optionally it may contain one <domain-name>, one <host-name>, any number of <subtype> and any number of <txt-record> elements. The attribute protocol specifies the protocol to advertise the service on. If any is used (which is the default), the service will be adver- tised on both IPv4 and IPv6. <type> Contains the DNS-SD service type for this service. e.g. "_http._tcp". <subtype> Contains an additional DNS-SD service subtype for this service. e.g. "_anon._sub._ftp._tcp". <domain-name> The domain name this service should be registered. If omited defaults to the default domain of the avahi daemon. (probably .local) <host-name> The host name of the host that provides this service. This should be a host that is resolvable by multicast or unicast DNS. Please note that you need to specify a fully-qualified domain name (FQDN) here, i.e. .local is not appended implicitly! The host name doesn't need to be part of the domain specified in <domain-name>. See avahi.hosts(5) for more information how to publish additional host name mappings. <port> The IP port number the service listens on. <txt-record> DNS-SD TXT record data. AUTHORS
