[opensuse] What to use for determining a "route"
Hello to everyone reading this. Provided i wish to determine my route(s) on my network. which of these packages is NOT deprecated: iproute, iproute2, netstat (is deprecated). The first two I do not know. Have they all been superseded by "ss"? I am a bit lost on what is still maintained and what not. Formerly I used e.g. arp but I have read it is deprecated. Netstat too. Thanks in advance for updating me on what to use and..why the older package were "deprecated". Especially the latter would help my understanding.

iproute2 is all you need.

iproute2 is a package, which contains e.g. "ip" and "ss". -- Per Jessen, Zürich (8.1°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland.

These days, the ip command is used for much of that and replaces ifconfig and a couple of others. I suspect the reason they were depricated was to rationalize things with IPv6. Arp is still around, but is IPv4 only. IPv6 uses neighbour discovery and advertisement, both of which are part of ICMP6. Arp isn't even part of IPv4, as it predates it.

Yes, they are both deprecated. use 'ip neigh' instead of arp. -- Per Jessen, Zürich (7.9°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland.

Wow, that was a very useful suggestion, i did never read about the command. Great. I am afraid I am going to do another stupid question now, but I am doing it in a new thread.

The links above tell at least part of the history. The second one at utoronto, seems to be good, and the one at ubuntu. Apparently the tools get the information from /proc, while newer tools use netlink sockets. This limits what they can do. And they don't present all the information. -- Cheers / Saludos, Carlos E. R.
