hi all! i have a very strange problem with samba: when i try to copy some files with samba the connection freeze and after some time i get can read in my log file: Sep 16 22:47:35 srv01 smb_add_request: request [dd6d1e40, mid=29034] timed out! Sep 16 22:48:36 srv01 smb_add_request: request [dd6d1e40, mid=34953] timed out! Sep 16 22:49:06 srv01 smb_add_request: request [dd6d1e40, mid=34954] timed out! Sep 16 22:49:36 srv01 smb_add_request: request [dd6d1e40, mid=34955] timed out! Sep 16 22:49:36 srv01 SMB connection re-established (-5) what i allready did: i tried the masked samb version samba-3.0.20-r1 i tried these parameter in my smb.conf: use sendfile = no large readwrite = no max xmit = 16644 i tried to mount my NT4 share with cifs but i only get: mount error 111 = Connection refused i upgraded my kernel to the latest gentoo-sources 2.6.13-r1 i changed my network card from forcedeth to a 8139too card now i downgraded my kernel to 2.6.9-gentoo-r9 but the problem is the same. i installed samba 3.0.6-r4 and no luck (i tried many different kernels) btw.: the same kernel and samba version is working on different hardware without problems. i'm using a router (with openwrt.org linux installed) which is working fine and i can transfer many, many gigs wich many other protocols (ftp, scp, http). could it be the router? but i don't know how to find out what exactly causes this problem. i sniffed the communication on the router and got "checksum incorrect". does anyone know how to solve this problem? and now i have no idea what to do next :-( cheers
