However, several data processing software programs like, HKL Suite, Mosflm, and DPS are still available only in UNIX (or Linux) O/S. This invariably meant that one has to transfer the data collected at Windows NT machine to one of the Linux machines (usually raccoon) before processing. Since only secure connections are allowed between machines, the transfer usually takes a long time, typically one minute per frame (100-150 kb/s). In addition, the frames being transferred are never in the order in which the data had been collected thus delaying data processing until all the data is transferred. With the help from the Computer Resources we have added a new way to transfer the data that circumvents several of the above mentioned problems. This transfer makes use of one of the programs from Samba Suite called smbclient. Another software addition the XRF has implemented is the ability to view the data being collected at XRF from DRS (currently available only for IP detector) without having to walk over to the Facility. This is provided by a service called vnc which is started up when the detector computer (anaconda.sb.fsu.edu) is turned on. The progress of the data collection can then be followed by any Java capable browser within the Kasha Laboratory Building (KLB). It is even possible to remotely modify the data collection conditions using the browser. However, at this stage we are recommending that users use the program only to follow the progress rather than modify it since it is quite possible to stop the data collection accidentally that may require human intervention to restart. Please save the Tips for future reference. A copy of the Tips will be posted in XRF webpage shortly after receiving suggestions and corrections from the users. smbclient Computer Resources has installed software called samba in raccoon.sb.fsu.edu. This software allows two machines with two different operating systems to communicate effectively thus allowing file transfer and file system mounting without the user needing to worry about the different protocols. Part of the Samba Suite available from www.samba.org is a utility called smbclient, which resides in the Linux (UNIX) side of the client/server connection. Smbclient provides an ftp-like connection between a native Linux (Network File System NFS) machine and a Windows NT machine (Common Internet File System (CIFS)/SMB protocol). This allows quick file transfers between two different machines. In addition, there is no need for the Windows NT machine to be running a FTP server; the requests are handled via Windows NT share. Using smbclient it is now possible to transfer files from anaconda.sb.fsu.edu to any Linux/UNIX machine (say, raccoon.sb.fsu.edu) very quickly. Since the transfer is not encrypted, the process is fast (~2 Mb/s, compared to 150 kb/s with sftp). Another advantage is that since the transfer is initiated from Linux side and NOT from the NT side, the E:\Soma\My Documents\XRAY\CY2004Facility\SoftWareTips-1.doc 3Thayumanasamy Somasundaram Page 4 8/20/2004 user can initiate the transfer from any machine that allows a secure connection to the Linux box. smbclient session: Given below is a typical smbclient session where data collected at Windows NT machine (anaconda) is transferred to a Linux (raccoon) machine. Note: (Courier Font: machine output; Bold Italic Courier Font: user input; Garamond Font: comments; ↵ : Enter or Carriage Return). Log into the Linux machine raccoon and at the prompt issue the following command to query the Windows NT machine for all allowed shares from which we will get our files (during a regular transfer query session can be omitted, given here only for completeness): soma@raccoon[10:15am]~>smbclient -L \\\\anaconda -U soma ↵ a simpler alternative is to use single quotes (‘ ‘) and required (less) backslashes, soma@raccoon[10:26am]~>smbclient -L ‘\\anaconda’ -U soma ↵ added interface ip=128.186.103.108 bcast=128.186.103.255 nmask=255.255.254.0 Note the use of backslashes (\\\\ or single quotes and ‘\\’). Now provide the password for the Windows NT machine, for
