I started a xmap instance on Azure virtual machine, Azure only provide IPv6 balance, not point to point (/128) public address, middle-ware convert. It can ping IPv6 address correctly and can be accessed via IPv6 address, but xmap does not work. I tried to capture network packets when scanning. Sniffer packet sent but no response(like www.sdu.edu.cn and www.sdwu.edu.cn, the two alive hosts I do promise I can correctly ping, but xmap cannot detect up). Alternatively, another provider, Ubuntu20 installed, with p2p IPv6 and I got public IPv6 add via ifconfig->eth0, but ./xmap output:

Jan 08 08:17:48.907 [ERROR] get_gateway-linux: interface specified (eth0) does not match the interface of the default gateway (). You will need to manually specify the MAC address of your gateway. Jan 08 08:17:48.907 [FATAL] xmap: could not detect default gateway address for eth0. Try setting default gateway mac address (-G).

arp -a no record, curious.

followed all the steps within the INSTALL:md file but getting this error on make:

trying on a vm with ubuntu 20.04 and installed all the deps, any ideas ? thanks

When I run this cmd on centos 8, something is missing:

sudo yum install -y cmake gmp-devel gengetopt libpcap-devel flex byacc json-c-devel libunistring-devel

error:

No match for argument: libpcap-devel No match for argument: libunistring-devel Error: Unable to find a match: libpcap-devel libunistring-devel

solution: sudo yum -y install cmake gmp-devel gengetopt flex byacc json-c-devel sudo dnf --enablerepo=powertools -y install libpcap-devel libunistring-devel

When I build files, something is error:

cmake . cmake: symbol lookup error: cmake: undefined symbol: archive_write_add_filter_zstd

try this: sudo yum install -y libarchive cmake .

Help

Type xmap -4 -h -M dnsx -O json to show the help information.

This module sends out DNS queries and parses basic responses. By default, the module performs an A record lookup for www.qq.com. You can specify other queries using the --probe-args argument in the form: label_type:input_src:type,query;type,query, e.g., raw:text:A,qq.com;NS,qq.com. The module supports sending the the following types of queries: A, NS, CNAME, SOA, PTR, MX, TXT, AAAA, RRSIG, ANY, SIG, SRV, DS, DNSKEY, TLSA, SVCB, HTTPS, CAA, and HTTPSSVC. The module will accept and attempt to parse all DNS responses. There is currently support for parsing out full data from A, NS, CNAME, MX, TXT, and AAAA. Query format: label_type:recurse:input_src:type,query;type,query Any other types will be output in raw form.  label_type: raw, str, time, random, dst-ip   raw: do nothing to the query domain, e.g., qq.com   str: add the 'str' subdomain www, e.g., www.qq.com   time: add the s+μs subdomain, e.g., 1620027515-568043.qq.com   random: add random subdomain lefzwnrq, e.g., lefzwnrq.qq.com   dst-ip: add probe num + src ip, e.g., 1.1-2-3-4.qq.com  recurse: recurse, no-recurse   recurse: recursive query   no-recurse: non-recursive query  input_src: text, file   text: like A,qq.com;AAAA,qq.com   file: each line is like a text  type: A, NS, CNAME, SOA, PTR, MX, TXT, AAAA, RRSIG, ANY, SIG,   SRV, DS, DNSKEY, TLSA, SVCB, HTTPS, CAA, and HTTPSSVC  query: A,qq.com;AAAA,qq.com Examples:  --probe-args="raw/time/random:recurse/no-recurse:text:type,query"  --probe-args="raw/time/random:recurse/no-recurse:file:file_name"  --probe-args="str:SomeText:recurse/no-recurse:text:type,query"  --probe-args="str:SomeText:recurse/no-recurse:file:file_name"  --probe-args="dst-ip:recurse/no-recurse:text:type,query"  --probe-args="dst-ip:recurse/no-recurse:file:file_name"

Usage Examples

1. Query qq.com A targeting 8.8.8.8:

xmap -4 -x 32 -p 53 -M dnsx -O json --output-fields="*" --output-filter="success = 1 || success = 0" -P 1 --probe-args="raw:recurse:text:A,qq.com" -R 1000 -o result.txt 8.8.8.8

2. Query qq.com A and baidu.com NS targeting 8.8.8.8:

xmap -4 -x 32 -p 53 -M dnsx -O json --output-fields="*" --output-filter="success = 1 || success = 0" -P 2 --probe-args="raw:recurse:text:A,qq.com;NS,baidu.com" -R 1000 -o result.txt 8.8.8.8

3. Query each domain from a domain.txt targeting all IPs from a ip.txt:

xmap -4 -x 32 -p 53 -M dnsx -O json --output-fields="*" --output-filter="success = 1 || success = 0" -P domain_number --probe-args="raw:recurse:file:domain.txt" -R 1000 -o result.txt -I ip.txt

Note: Each line in domain.txt is in the form like A,qq.com and -P domain_number = the number of domains.

Show probe modules:

$ ./src/xmap -6 -h -M icmp_echo_tmxd Probe-module (IPv6 icmp_echo_tmxd) Help: Probe module that sends ICMPv6 echo requests to hosts for discovering routers with routing loop. And the following argus should be set: --iid-module=rand --iid-num=2 --probe-ttl=64 (max) --probes=2 (2 packets with ttl=64,63) (`repeat' key: <IPv6, ICMPv6-type>) Payload of ICMPv6 packets will consist of 8 bytes zero unless you customize it with: --probe-args=file:/path_to_payload_file --probe-args=text:SomeText --probe-args=hex:5061796c6f6164 --probe-args=icmp-type-code-str

Describe the bug

Once I run a simple command, there is a Segmentation fault error.

To Reproduce
