[Samba] SMB3 Unix Extensions - creating special files
Hi, I've created a few network traces which will hopefully help. Each one contains the initial mount command, followed by a single command. They're hosted here: https://filebin.net/zvdx07i2m3lta129 Working: samba_stat_symlink.pcap = stat /mnt/sym_a_local Not working: samba_ln_s.pcap = ln -s /mnt/a.txt /mnt/a.symlink samba_mkfifo.pcap = mkfifo /mnt/fifo_new Hopefully that will give some idea about what's happening but let me know if you need any other traces or debug info.

...adding linux-cifs and Steve to the loop.... Looks to be a client issue: the client is checking for existence of the targets, the server returns ENOENT and then that's it. There no attempt to create either a symlink nor the fifo as reparse points. @Steve: any idea of what could be going wrong? Iirc this is supposed to be working in the client. -slow On 7/30/25 2:31 PM, Matthew Richardson wrote:> Hi, > > I've created a few network traces which will hopefully help.
