Hi, I have fc6 x64 and wanted to run addprinter command it fails reporting Cannot connect to server. Error was NT_STATUS_IO_TIMEOUT ok I 'm trying very simple command rpcclient -d 0 -U nz -c 'srvinfo' -I 192.168.1.35 fc6x64 Password: Cannot connect to server. Error was NT_STATUS_IO_TIMEOUT I wonder what to check to figure out what is wrong . It works ok for xp sp2 box rpcclient -d 0 -U nz -c 'srvinfo' -I 192.168.1.5 NZDELL820 Password: NZDELL820 Wk Sv PrQ NT PtB LMB platform_id : 500 os version : 5.1 server type : 0x51203 rpm -qa | grep samba system-config-samba-1.2.35-1.1 samba-client-3.0.23c-2 samba-3.0.23c-2 samba-common-3.0.23c-2 samba-common-3.0.23c-2 I did tcpdump of session for smb and then see it in ethereal. I don't understand SMB packet semantics but it seems problem is authentication, at least there are packets in both side but server side closes connection very quick. BTW smb shares works ok for fc6x64. Thank in advance. --Nick Zhokhov
