Hi, I just installed RedHat 6.0 and samba-2.0.6. The compile and installation look okay. I set password server to our NT server. Then, I test it by running: /usr/local/samba/bin/testparm I got (home is the only service provided on this Linux system): Processing section "[homes]" Loaded services file OK. Press enter to see a dump of your service definitions ... [homes] comment = Home Directories read only = No However, when I run smbclient, I got error: /usr/local/samba/bin/smbclient -L elyback added interface ip=128.252.85.78 bcast=128.252.255.255 nmask=255.255.0.0 protocol negotiation failed "elyback" is this RH 6.0 system. Can somebody tell me what "protocol negotiation failed" means? How to fix it? I appreciate all the help! H. Li
