It appears that the kernel defaults to no UDP support be set as default. The NFS man page has not yet caught up with the disablement of UDP. and version=2. The kernel config does indicate V2 is not set but does not indicate what the default is but also added this option CONFIG_NFS_DISABLE_UDP_SUPPORT and if not set but it defaults to "Y", so no UDP since that is not set. It also seems portmapper still has UDP and version=2 but the kernel does not have either vers=2 or UDP (vers=2 possibly disabled because no UDP, and I seem to remember vers=3 was the first with tcp and initial it would not work with >255 clients, I worked with a client that upgrade from 240 nodes, to 260 nodes and starting going over the limit). So a lot of the tools and documentation does not match the current set of kernel config option being used, or someone did not set the kernel options to enable UDP. _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
