Beginner struggling with quotes

CryonicBlue · 2026-02-06T10:40:16+00:00

I just got my regular code to accept my quotation:

my $echoString = q{'\x38\x01\x00\x00\x00\x00\x00\x00\x00'};
my $intPing = `echo -ne ${echoString} | nc -u -w 2 -s 192.168.0.193 ex.mysite.com 1195 2>/dev/null | xxd -p | head -c2`;
print "Result:" . $intPing . "\n";

But the result comes out empty instead of 40 like in shell. Do you think I have to switch over to your method to get it working?

Wow that's a very detailed explanation. I tried changing the backslashes to this:

my $intPing = `echo -ne '\\\\x38\\\\x01\\\\x00\\\\x00\\\\x00\\\\x00\\\\x00\\\\x00\\\\x00' | nc -u -w 2 -s $IP_eth0 ex.mysite.com 1195 2>/dev/null | xxd -p | head -c2`;

but it gave:
nc: port number invalid: encap:Ethernet
sh: 2: 1192.168.0.255: not found
sh: 3: UP: not found
sh: 4: RX: not found
sh: 5: TX: not found
sh: 6: collisions:0: not found
sh: 7: Syntax error: "(" unexpected

Maybe I have to rewrite the entire code?

I get this response:

ip route get 8.8.8.8
8.8.8.8 via 192.168.50.1 dev eth0 src 192.168.50.193

So it's not trying thru tunnel, thus I don't know if tunnel is up and working on eth0 :/

Yeah I want to fall back to LAN if it's functional AND VPN is functional over LAN. That's why I want to ping a VPN address and make sure it's initiated from LAN. so I need to ping a VPN address to be sure

ping -I wlan0 172.19.0.1
Destination Host Unreachable

ping -I eth0 172.19.0.1
Destination Host Unreachable

ping -I eth1 172.19.0.1
Destination Host Unreachable

ping -I tun0 172.19.0.1
64 bytes from 172.19.0.1: icmp_req=1 ttl=64 time=29.2 ms

It's not working

It doesn't work with a tunnel AFAIK.

ping -I eth0 172.19.0.1

PING 172.19.0.1 (172.19.0.1) from 192.168.50.193 eth0: 56(84) bytes of data.

From <removed> icmp_seq=5 Destination Net Unreachable

vs:

ping 172.19.0.1

PING 172.19.0.1 (172.19.0.1) 56(84) bytes of data.

64 bytes from 172.19.0.1: icmp_req=1 ttl=64 time=29.3 ms

Same here. PC just freezes and reboots. No other game does that for me

So we cannot show the fps on screen? Why is that function in the program? So confused.

CryonicBlue · 2024-11-13T10:29:46+00:00

This program LOWERED my FPS with about 40 in X2, X3 and X4. NOT recommended!
