Hi! I have several linux boxes, that need to be backed up. I wrote a small script for this task that simply creates a .tar.gz file with alle the important stuff in it. The tape drive is connected to a windows box, so the script also mounts a windows share and copies the .tar.gz file. Unfortunately I get errors from time to time when the script copies large files (>200 MB). Small files (<100 MB) are copied without a problem. This is the output I get back from cron: cp: writing `/mnt/heribert/2003-07-28.FULL.galileo.tar.gz': Input/output error I also checked the syslog for the specific time, the copy took place: Aug 11 19:11:36 galileo kernel: smb_get_length: recv error = 5 Aug 11 19:11:36 galileo kernel: smb_request: result -5, setting invalid Aug 11 19:11:36 galileo kernel: smb_writepage_sync: failed write, wsize=4096, result=-5 Aug 11 19:11:36 galileo kernel: smb_retry: successful, new pid=19729, generation=2 Any chance, that the firewall could be the problem (the linux box stands in the dmz and the windows backup server in the internal lan)? For test purposes I opened all ports between those two machines...no effect. Any help would be great. Thnx, Patrick
