I hope there's someone out there can help me! I would appreciate if one of you did so. I have some problems with samba: I use samba 1.9.18p10 with SuSE Linux 6.0 W95,DOS Clients. i. Lines in log.smb : "Unknown socket option TCP_NODELAY" ? ii. oplock_break:cannot find open file with dev='n',inode=q,(fnum=k) allowing break to succeed. Does it mean that a client wants to cache (preraed) a file which has been deleted yet? iii. The limit of the concurrently open files is per connection or per session or a global feature or ...? iv. The main thing: I changed from Novell Netware to Samba.The amount of performance loss was huge. Something must be very wrong, because I use the same hardware as 'under' Netware.I paid attention to everything about performance in 'man smb.conf' and smb HowTo and result is the same, it's unimaginably slow. I think there's some problem at the clients' side (I had to change to TCP/IP from IPX/SPX), WHAT CAN IT BE? Yours, M?t? Lajtos
