[Samba] Connection time-out opening documents since system update and reboot - update
Hi,
Since my original post additional testing has been carried out as below:
1/ Connecting via a wired ethernet connection - no difference.
2/ SFTP - works as expected.
3/ SCP - works as expected.
A small file of 414 bytes open as expected, anything bigger hangs.
The through-put has been checked on the ethernet port and is as expected
using the above protocols.
I have run the command 'smbstatus' to obtain the process id and then run
a strace:
strace -fttv -p <process id>
It just hangs as below finally:
10:46:59.153083 write(9, " send_file_readX fnum 51715 max"..., 49) =
49
10:46:59.153133 writev(16,
[{iov_base="\0\0\4:\377SMB.\0\0\0\0\200\3\310\0\0\0\0\0\0\0\0\0\0\0\0L}\257\17"...,
iov_len=1086}], 1
It eventually advises it has timed out in the client program opening the
file.
If anybody has any thoughts why this is occurring and assistance they
can suggest, that would be appreciated.
Many thanks
Daniel
