The available parameters for src and their default values are: Strings: workgroup - The name of the workgroup or domain of the server. Default: blank server - The name or IP address of the server hosting the resource (share). Default: blank share - The name of the desired server resource (share). Default: blank user - The username for authentication. Default: guest password - The password of the selected user. Default: blank spassword - The share-level password of the selected user. Default: blank master - The name of the browse master server or workgroup, used to get the list of available workgroups when the workgroup and server have not been specified. Default: WORKGROUP mastertype - The type of master selected (1 = workgroup; 0 = server) Default: 1 cto - The time in seconds for which the cache is valid. Once the timeout is reached, the client re-reads the directory. For a directory with many files, it may be better to increase the timeout (rule of thumb: per 500-800 files 10 seconds). Max: 600 Default: 10 cld - The number of directories the cache should hold. Be aware that the higher the value, the more memory consumed. Max: 96 Default: 32 easupport - (Boolean) Support OS/2 Extended Attributes in the target filesystem (and by the target server). Default: 1 krb5support - (Boolean) Support Kerberos authentication. You will need to have a valid ticket for this resource. If enabled, User ID and Password are ignored. Note: If 1, ntlmv1support must be 0 Default: 0 ntlmv1support - (Boolean) Authenticate using the older NTLM protocol. Newer Samba releases default to NTLMv2, which may not be understood by some older servers. Note: If 1, KRB5 and supportencryption must both be 0 Default: 0 encryptionsupport - (Boolean) Enable transport encryption over SMB3 links. Although Samba servers have supported encrypted transport connections using the UNIX extensions for many years, selecting SMB3 transport allows encrypted transport connections to Windows servers that support SMB3, as well as Samba servers. Note: If 1, ntlmv1support must be 0 Default: 0 Example: src = 'workgroup=homegroup;server=192.168.178.2;share=data; \ user=test;password=pass;spassword=;master=homegroup; \ mastertype=1;cto=30;cld=64;easupport=1;krb5support=0; \ ntlmv1support=0;encryptionsupport=1' This assumes a Samba resource of \\192.168.178.2\data using NTLMv2 authentication over SMB3 supporting encryption, with support for extended attributes in the target filesystem and by the Samba host server, in the homegroup workgroup.
