This command is used by client to set/unset modes for itself.
However, there are some modes that the client MUST NOT set itself,
0x00000002 SILC_UMODE_ROUTER_OPERATOR
Marks the user as router (SILC) operator. Client
- MUST NOT this mode itself. Router sets this mode to
- the client when client attains the router operator
+ MUST NOT set this mode itself. Router sets this mode
+ to the client when client attains the router operator
privileges by SILC_COMMAND_SILCOPER command. Client
MAY unset the mode itself.
Client MAY set and unset this mode.
+ 0x00000100 SILC_UMODE_ANONYMOUS
+
+ Marks that the client is anonymous client. Server
+ that specificly is designed for anonymous services
+ can set and unset this mode. Client MUST NOT set or
+ unset this mode itself. A client with this mode set
+ would have the username and the hostname information
+ scrambled by the server which set this mode.
+
+
+ 0x00000200 SILC_UMODE_BLOCK_PRIVMSG
+
+ Marks that the client wishes to block private
+ messages sent to the client, unless the Private
+ Message Key flag is set in the SILC packet header.
+ If this mode is set server MUST NOT deliver private
+ messages to the client without the Private Message
+ Key flag being set.
+
+ A separate service could provide additional filtering
+ features for accepting private messages from certain
+ sender. However, this document does not specify such
+ service.
+
+ The client MAY set and unset this mode.
+
+
+ 0x00000400 SILC_UMODE_DETACHED
+
+ Marks that the client is detached from the SILC network.
+ This means that the actual network connection to the
+ client is lost but the client entry is still valid. The
+ detached client can be resumed at a later time. This
+ mode MUST NOT be set by client. It can only be set when
+ client has issued command SILC_COMMAND_DETACH. The server
+ sets this mode. This mode cannot be unset with this
+ command. It is unset when the client is resuming back to
+ the network and SILC_PACKET_RESUME_CLIENT packet is
+ received.
+
+ This flag MUST NOT be used to determine whether a packet
+ can be sent to the client or not. Only the server that
+ had the original client connection can make the decision
+ by noticising that the network connection is not active.
+ In this case the default case is to discard the packet.
+
+ If the <client mode mask> was not provided this command merely
+ returns the mode mask to the client.
