Hi!
I have no enough experience with natd, so my question:
What does the natd's -use_sockets option?
`man natd' says:
-use_sockets | -s
Allocate a socket(2) in order to establish an FTP data or IRC
DCC send connection. This option uses more system resources,
but guarantees successful connections when port numbers con-
flict.
But in alias.h I see:
/* If PKT_ALIAS_USE_SOCKETS is set, then when partially specified
links (e.g. destination port and/or address is zero), the packet
aliasing engine will attempt to allocate a socket for the aliasing
port it chooses. This will avoid interference with the host
machine. Fully specified links do not require this. */
I don't undestand the {FTP data connection} and {partially specified links}
relationship. What is it? Please, explain.
TIA,
---
