Hi,
I have a NAS that serves files via Samba. The NAS runs Debian 12.7 and Samba version 4.17.12-Debian. I can connect to the NAS from a Mac, from an iOS device, and from two different Android (14, 15) devices without any issues, using the very same user account. However, when I try to connect from a Gentoo machine I simply can't, no matter what I do.
The Gentoo machine is in the same network as all other devices. It runs an up-to-date Gentoo version with Kernel 6.11.4 and mount.cifs version 7.0. I have enabled debugging using the following commands:
| Code: |
echo 'module cifs +p' > /sys/kernel/debug/dynamic_debug/control
echo 'file fs/cifs/* +p' > /sys/kernel/debug/dynamic_debug/control
echo 7 > /proc/fs/cifs/cifsFYI
|
I manually run mount as follows:
| Code: |
mount -v -t cifs -o workgroup=XXX,username=toni,uid=1000,gid=1000 //192.168.1.3/toni /mnt/nas/
|
The command returns the following output:
| Code: |
mount error(115): Operation now in progress
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)
|
When I check dmesg, I see the following output:

No matter what sec or vers option I try, the result is the same. However, if I use smbclient like this:
| Code: |
smbclient -U toni //192.168.1.3/toni -c "dir"
|
... it returns the content of the home directory without any issues. This means that my machine is able to reach the server, connect to it and authenticate successfully.
Does anyone have an idea of what might be wrong with CIFS? Thank you. |
