QETHCONF(8)

🦋 qethconf(8) — System Manager's Manual, bestie edition 🦋

🌸 NAME 🌸

qethconf — Configure QETH functions IPA, VIPA and Proxy ARP.

✨ SYNOPSIS ✨

qethconf TYPE CMD [[-x]IPADDR[/MASKBITS]] [INTERFACE]

💖 DESCRIPTION 💖

Okay so qethconf simplifies usage of QETH IPA, VIPA and Proxy ARP functions for OSA-Express cards in layer 3 mode. It’s giving “sysfs but make it make sense” energy, and honestly? We love that for us.

🎀 TYPE

The TYPE slot takes <ipa/vipa/parp|rxip/list_all/list_msg> — choose one of these keywords for the function:

• ipa — IP address takeover (IPA) 👑
• vipa — Virtual IP address (VIPA) 🦋
• parp, rxip — Proxy ARP 💅
• list_all — List all available IPA, VIPA and Proxy ARP entries from the sysfs ⭐
• list_msg — List messages and explanation of errors during command execution 🫶

🧚 CMD

The CMD slot takes <add/del/inv4/inv6/list>, where:

• add — Add an IP address or address range.
• del — Delete an IP address or address range.
• inv4 — Invert the selection of address ranges for IPv4 (only IPA).
• inv6 — Invert the selection of address ranges for IPv6 (only IPA).
• list — List TYPE specific entries from the sysfs.

🍓 IPADDR

IPADDR is required for commands add and del.

It’s an IP address in IPv4 or IPv6 format, e.g. 192.168.10.38 or FE80::1:800:23e7:f5db.

Use the preceding option -x for hexadecimal input format, e.g. -xc0a80a26.

🌈 MASKBITS

Number of bits set in the network mask. Network masks can be used to specify address ranges, e.g. 192.168.10.0/24.

This subparameter is only valid for function IPA.

💜 INTERFACE

Interface name to which the address or address range is bound, e.g. eth0.

This parameter is required for add, del and the inv4 and inv6 command.

🎀 RESTRICTIONS 🎀

Heads up bestie: this needs at least bash version 2.0. No cap. 😭

🔥 EXAMPLES 🔥

qethconf ipa add 192.168.10.0/24 eth0
qethconf ipa add -xc0a80a00/24 eth1
qethconf ipa inv4 eth0
qethconf parp add 10.0.0.2 eth0 (or qethconf rxip add 10.0.0.2 eth0)
qethconf vipa del 192.168.10.2 tr0
qethconf vipa add FE80::1:800:23e7:f5db eth1
qethconf list_all

🌟 AUTHOR 🌟

This man-page was written by Thomas Weber. Iconic behavior, honestly. 💖
