Package: sendip Version: 2.6-1 Severity: normal Dear Maintainer,
trying to send TCP SYN packet to 87.250.250.242:443 with # sendip -v -p ipv4 -is 172.31.39.82 -id 87.250.250.242 -p tcp -ts 1234 -id 443 -tfs 1 87.250.250.242 Added 47 options Initializing module ipv4 Initializing module tcp Finalizing module tcp Finalizing module ipv4 Final packet data: 45 00 00 28 E..( 1E F7 00 00 ....

Setting socket options: IP_HDRINCL Sent 40 bytes to 87.250.250.242 Freeing module ipv4 Freeing module tcp I got via tcpdump: listening on wlan0, link-type EN10MB (Ethernet), capture size 262144 bytes 11:58:45.520319 IP 172.31.39.82.1234 > 0.0.1.187.0: Flags [S], seq 712925297, win 65535, length 0 So, ipv4 destination address is broken, and line "00 00 01 BB" from sendip output confirms that ipv4 header is corrupted. Destination port is also wrong. -- System Information: Debian Release: bullseye/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.17.0-1-amd64 (SMP w/2 CPU threads) Kernel taint flags: TAINT_WARN Locale: LANG=ru_RU.UTF-8, LC_CTYPE=ru_RU.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) Versions of packages sendip depends on: ii libc6 2.30-4 sendip recommends no packages. sendip suggests no packages. -- no debconf information
