17This directory builds a program linking all of the SMB server code
18into a user-level process. The result is not a fully functional
19SMB server but is very useful for some kinds of development work.
21The architecture of this roughly parallels the in-kernel version,
22where the fksmbd program corresponds to the real smbd, the library
23libfksmbsrv corresponds to the smbsrv kernel module, and all the
24required kernel interfaces are simulated in libfakekernel.
26Just as with the kernel code, there are mdb modules that know
27how to walk data structures in libfksmbsrv, etc.
29For debugging, etc. it's easiest to run this as a normal user,
30i.e. yourself (not root); but before you can do that, there are
31some prerequisites to take care of:
33 a: Install ../bind-helper in /usr/lib/smbsrv/.
34 It needs to be either setuid root (easiest) or added to
35 the exec_attr as described in the top of bind-helper.c
36 (This must be in /usr/lib/smbsrv, not the proto area.)
38 b: Setup an SMB account for guest, i.e.
39 Add pam_smb_passwd.so.1 to pam.conf if not already there
40 (other password required pam_smb_passwd.so.1 nowarn)
41 % useradd guest
42 % smbadm enable-user guest
43 % passwd guest (sets the SMB p/w hash too)
44 Make sure guest shows in /var/smb/smbpasswd
46 c: chown/chmod the directories: /var/smb /var/run/smb
47 to yourself, mode 755. Reboot will chown these
48 back to root, so repeat this after a reboot.
50Now you can run fksmbd from the proto area using this script:
51 ./Run.sh -df
53You can also run it under dbx (see the .dbxrc file).
54To run it under mdb (with mdb modules build here):
55 mdb -L $ROOT/usr/lib/mdb/proc:/usr/lib/mdb/proc ...
56where ... is one of: fksmbd, core.nnn, -p $PID
58There are also some dtrace scripts in here, and in ../dtrace
59for watching either all activity or only selected areas.
60Run these like: dtrace -s Watch-all.d -p $PID -o output
62These two (from over in ../dtrace) also work with fksmbd:
63 dtrace -s smbd-authsvc.d -p `pgrep fksmbd` -o output
64 dtrace -s smbd-pipesvc.d -p `pgrep fksmbd` -o output
67Here are a couple simple, handy tests you can try:
69smbclient -L localhost -U guest%guest
71smbclient //localhost/test -U guest%guest -c dir
73smbtorture //localhost/test -U guest%guest base
