Error Writing 5 Bytes To Client. Samba
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] I'm having irregular disconnecting of win2k/xp clients from our samba PDC (fileserver). I've been reading a lot, searching through google,comparing other smb.conf out on the web, but most seem to have more or less the same main parts and nothing has solved the problem yet. Sometimes it happens when i start my windows explorer to browse my HD, but not all of the time I've also seen it happen when clients can't find their roaming profiles (sometimes happening) When e.g. my pc dc's from samba shares, i'm still able to connect through Putty (ssh) without a problem. I've been searching through the logs and each time a client dc's, something like this happens: lib/util_sock.c:write_data(562) ... Error writing 5 bytes to client. -1.

(Connection reset by peer) Now, from other sources, this seems quite normal. The problem seems to be that WinXP clients try to connect both to port 139 and 445 and then keep open only the session which is answered first and close the other (see e.g. http://ntsecurity.nu/papers/port445/). There are several solutions, but none seem really good: - add "ports 139" to smb.conf; problem: clients suppoting cifs (e.g. WinXP+) must revert to netbios over tcp which is less efficient - add "ports 445" to smb.conf; problem: clients not supporting cifs but only netbios over tcp cannot access the server anymore - disable netbios over tcp on winxp+ clients; problem: these clients would not be accessible by older clients anymore and furthermore you'd lose ot

0 Trophy Points: 1 Good afternoon all. I have a Freenas with a couple of CIFS shares. I've set Only "Allow Guest Access" to them, but put down a few hosts in "Hosts Allow" section (every host have a static IP). Everything works fine, but I'm constantly receiving this kind of messages (x.x.x.119 is the one that have access to CIFS shares): Jan 29 09:31:20 freenas smbd[22295]: STATUS=daemon 'smbd' finished starting up and ready to serve connectionsreceive_smb_raw_talloc failed for client ipv4:x.x.x.119:1128 read error = NT_STATUS_CONNECTION_RESET.

(Broken pipe) As far as I'm concerned, my shares works fine, but it's a bad idea to ignore error messages. Is there a way to fix it? Any and all advice/comments/questions are greatly appreciated, and thanks for reading! P.S. Sorry my English. insomnium, Jan 29, 2015 #1 anodos Belly-button Lint Extraordinaire Joined: Mar 6, 2014 Messages: 3,393 Thanks Received: 660 Trophy Points: 111 Location: elbonia Post contents of /usr/local/etc/smb4.conf The message may be related to using 'hosts allow'. Honestly guest access +hosts allow is not a very good method of access control. All I'd need to do is wait till a client is down, and take it's IP address. Set up password authentication with proper permissions and get rid of 'hosts allow'.

But the boss don't want users to be interrupted by login/password screen. Mabye there is a way to use windows login/password to get access to the freenas? By the way, when one of the computers who can access the share is online, I receive a message like this: Jan 30 11:26:35 freenas smbd[84
