I receive this error message:
Device "SMB0:" not found in the file "DEVS:MountList:".
That would be because of the changes you made to the command Karlos gave you, there is no space and no colon.
I also need to use smbclient, not smbfs but the syntax is very much the same.
If i change the user-startup entry, "Mount SMB0", ie dropping the colon, nothing appears to happen at all.
If you need to use smbclient you're stuck with command line usage, you get no nice device access like smbfs provides. Is there any reason why you would not want to use smbfs?
