I have a Linux socket server program. I need to run the commands sent by the client and return the output to client. Is there a quicker way?
I tried with
ptr=popen(command, "r"); and then
fgets(buf, size,ptr);
write buf to socket
fgets hangs for me.
Now, I would like to know if I can... (3 Replies)

avahi-publish-service(1) General Commands Manual avahi-publish-service(1)NAME
avahi-publish-service - Register an mDNS/DNS-SD service or host name or address mapping using the Avahi daemon
SYNOPSIS
avahi-publish -s [options] name service-type port [TXT data ...]
avahi-publish-service [options] name service-type port [TXT data ...]
avahi-publish -a [options] host name address
avahi-publish-address [options] host name address
DESCRIPTION
Register an mDNS/DNS-SD service or host name/address mapping using the Avahi daemon. The daemon is not the standard Avahi daemon but a
proxy to a Bonjour daemon.
OPTIONS
When calling in service registration mode, specify a DNS-SD service name (e.g. "Lennart's Files"), a service type (e.g. _http._tcp) and an
IP port number for the service, optionally followed by any number of TXT record strings on the command line. When calling in address/host
name registration mode specify a fully qualified host name and an address (IPv4 or IPv6).
-s | --service
Register a service. avahi-publish-service is equivalent to avahi-publish -s.
-a | --address
Register an address/host name mapping. avahi-publish-address is equivalent to avahi-publish -a.
-v | --verbose
Enable verbose mode.
-H | --host= HOSTNAME
Specify a host name for this service, in case it doesn't reside on the local host. This host name needs to be fully qualified and
resolvable using mDNS or unicast DNS.
-d | --domain= DOMAIN
Publish the service in the specified domain. If omitted the Avahi daemon will publish it in its default domain (usually .local).
--subtype= SUBTYPE
Register the service with an additional subtype in addition to the main type. DNS-SD subtypes have the form _anon._sub._ftp._tcp,
where _anon is the identifier of the subtype and _ftp._tcp is the main type. You may pass this option multiple times to register the
service with multiple subtypes.
-f | --no-fail
Don't fail if the daemon is not found running. Instead, wait until it appears. If it disconnects, try to reconnect.
-h | --help
Show help
-V | --version
Show version information.
