Describe the bug
When Sendto errors occur, after 10 are generated a message is sent informing the user that future errors will be omited which reads as follows:
Omitting future Sendto error messages now that 10 have been shown. Use -d2 if you really want to see them.
This message says that the omission can be bypassed by using the -d2 flag. However, after rerunning the scan with -d2, these errors are still omitted and no longer written to stderr. I additionally tried running a scan without -d2 and instead increasing the debugging level to 2 with the d key. Errors were still omitted.
The errors in question that I would like to continue being written to stderr look like this:
Offending packet: TCP 10.X.X.X:PORT > 10.X.X.X:PORT S ttl=54 id=19711 iplen=44 seq=4025177164 win=1024 <mss 1460>sendto in send_ip_packet_sd: sendto(9, packet, 44, 0, 10.X.X.X, 16) => Operation not permitted

To Reproduce
Block IPs via iptables firewall, and run a scan against them to generate Sendto errors. Attempt to use
-d2
to bypass the 10 error limit.Expected behavior
Using the
-d2
flag, or increasing debug level to 2+, should print all Sendto errors.Version info (please complete the following information):
nmap --version
:nmap --iflist
Not posting. I don't wish to leak client info and this error seems system independent.
