* tests: Use socat instead of netcatDavid Gibson2022-07-221-11/+11
| | | | | | | | | | | | | | | Commit 41c02e10 ("tests: Use nmap-ncat instead of openbsd netcat for pasta tests") updated the pasta tests to use the nmap version of ncat instead of the openbsd version, for greater portability. For some upcoming changes, however, we'll be wanting to use socat. "socat" can do everything "ncat" can and more, so let's move all the tests using host tools (either directly on the host or via mbuto generated images) to using socat instead.

* test: Embed script for dhclient(8) in mbuto(1) profileStefano Brivio2022-07-141-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | David reports that dhclient-script(8) on Fedora needs a number of binaries that are not included in PROGS of the current mbuto profile, and we would also need to include hostnamectl(1) there, which will fail without a systemd init. Embed a minimal script for dhclient(8) in the profile itself, written to /sbin/dhclient-script at boot, to just check what we need to check out of DHCP and DHCPv6 functionality. While at it, drop busybox and logger from PROGS, as we don't need them, and add hostname(1). While DHCP option 12 isn't supported yet by the DHCP implementation in passt, we should probably add it soon. Note: owing to the simplicity of this script, we now need to bring up the interface before starting dhclient: add this in test scripts where it's not the case yet.

* Tweak dhclient arguments for readabilityDavid Gibson2022-06-151-2/+2
| | | | | | | | | | | | | | A number of tests and examples use dhclient in both IPv4 and IPv6 modes. We use "dhclient -6" for IPv6, but usually just "dhclient" for IPv4. Add an explicit "-4" argument to make it more clear and explicit. In addition, when dhclient is run from within pasta it usually won't be "real" root, and so will not have access to write the default global pid file. This results in a mostly harmless but irritating error: Can't create /var/run/dhclient.pid: Permission denied We can avoid that by using the --no-pid flag to dhclient.

* Don't abbreviate ip(8) arguments in examples and testsDavid Gibson2022-06-151-11/+11
| | | | | | | | ip(8)'s ability to take abbreviated arguments (e.g. "li sh" instead of "link show") is very handy when using it interactively, but it doesn't make for very readable scripts and examples when shown that way. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

* test/two_guests: Fix sleep command for DADStefano Brivio2021-10-211-1/+2
| | | | | | | | | An inline comment prefixed by a space doesn't mean the space is dropped, and sleep(1) will get a blank in its argument. Move the comment on its own line. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
* test/two_guests: Let the guests end DAD before starting the DHCPv6 clientStefano Brivio2021-10-211-0/+1
| | | | | | | They'll start DAD as we bring up the interface, and the DHCPv6 client might be unreasonably delayed if we start it too early. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
