traceroute and friends broken again

[whorfin]

While #206 calls out fixes to traceroute , I find that on the latest 1.2.4 (370) build from Testflight, things are still broken. mtr also fails

[eutampieri]

Me too

[fegow]

Same here.

@tbodt, @saagarjha, I can confirm the issue with the latest 1.3 (482) from the App Store. Is it known? Output:

# traceroute 1.1.1.1
traceroute to 1.1.1.1 (1.1.1.1), 30 hops max, 46 byte packets
 1traceroute: sendto: Socket is connected

Same issue.

[saagarjha]

We’ve been tracking some networking bugs. This might be related to them?

I can also confirm this issue with 1.3.2 (494)

[dlstyley]

Same problem on iOS 17.3.1 and iSH 1.3.2

localhost:~# traceroute -v google.com

Same here for a fresh iSH install (Alpine Linux 3.14.3 / BusyBox 1.33.1):

~ $ traceroute -v 1.1.1.1
traceroute to 1.1.1.1 (1.1.1.1), 30 hops max, 46 byte packets
 1traceroute: sendto: Socket is connected

An existing install that runs the latest app updates does work (Alpine Linux 3.12.0 / BusyBox 1.31.1):

localhost:~# traceroute -v 1.1.1.1
traceroute to 1.1.1.1 (1.1.1.1), 30 hops max, 38 byte packets

I use traceroute to determine the default gateway in order to determine if I need to set up a tunnel or not. Other ways of determining the default gateway on a 'normal' linux installation (e.g. netstat -rn, ip route | grep default, etcetera) do not work. Using traceroute always did work, but now that appears to be broken as well.

traceroute -m 1 -q 1 -w 1 1.1.1.1|head -n 2|tail -n 1|awk '{print $2}'
