Hi.

Please I want to know the difference between /etc/services and /etc/init.d.
Secondly, I would want to know how to stop rwalld in ubuntu.

Thanks

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

Thanks pan64. Please do you also know how to stop rwalld.


Thanks

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.

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.

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
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.
