Hi! ---- While debugging a NFSv4.1 problem I noticed that the Linux nfsd somehow gets a "Implementation name" /proc/fs/nfsd/clients/*/info files: Example: ---- snip ---- $ cat /proc/fs/nfsd/clients/3/info clientid: 0x22d7004e65f1b8d3 address: "104.102.54.63:666" status: confirmed seconds from last renew: 15 name: "Linux NFSv4.2 DERGINB0666" minor version: 2 Implementation domain: "kernel.org" Implementation name: "Linux 5.10.0-22-rt-686-pae #1 SMP PREEMPT_RT Debian 5.10.178-3 (2023-04-22) i686" Implementation time: [0, 0] callback state: UP callback address: 93.240.185.34:0 ---- snip ---- How is this implemented, e.g. what does a NFSv4.1 client have to do to send the nfsd a "Implementation name" string ? ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) roland.mainz@xxxxxxxxxxx \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 3992797 (;O/ \/ \O;)
