/etc/services is a file, /etc/init.d is a dir. you can have detailed info about /etc/services by executing man services

that depends on your os, probably rwalld stop and rwalld start works...

init.d services have a number appended to them. This is the order in which the services are started and stopped during startup/shutdown. The services need to be started in order to provide dependencies between the services. starting or stopping a service with /etc/init.d/ does not provide the dependency. Often this does not matter. Using the service command is the 'new way' of starting/stopping services as this checks dependencies before starting/stopping the service.

for your service, have you tried 'service rwalld stop' or '/etc/init.d/rwalld stop'?

The file /etc/services is just a lookup table linking service names to port numbers. As you might know, networks work with numbers, not with names.

Code:
telnet somehost smtp
The telnet program will lookup 'somehost' to get the IP address of it by using whatever is specified in resolv.conf (dns, file /etc/hosts) and it will lookup 'smtp' in /etc/services. Internally it will use the IP address and the port number.

Difference between /etc/services and /etc/init.d

Thanks.

I have tried rwalld stop and it doesn't work. This is the error: "No command 'rwalld' found, did you mean:
Command 'rwall' from package 'rwall' (universe)
rwalld: command not found".


I also tried service rwalld stop and the error was: "unrecognized service". Tried rwall stop and it does nothing...
I can't even find it in the init.d directory.

One more question please, is rwall a protocol? If it is, what port number does it use in the /etc/services file?


Many thanks.

Just do a grep
Code:
grep rwall /etc/services
It will give you the line with the info (if it exists). I'm not behind a Linux machine to quickly check.

Thanks it worked. I guess rwall is not stored in /etc/services, because it worked for other protocols but didn't give any output for rwall. Or is rwall the same as netwall?


Many thanks.
