cant bind tun0 address to create a socks proxy

[cryptid11]

It runs correctly on both ends, but when I try to ssh -D 4444 root@10.0.1.1 nothing happens:

on server I run sudo ./icmptunnel -s 10.0.1.1, on client sudo ./icmptunnel -c serverip and I have:

$ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.0.0.0        0.0.0.0         255.255.255.0   U     600    0        0 wlp2s0
serverip    10.0.0.1        255.255.255.255 UGH   0      0        0 wlp2s0

and

$ ip a show tun0
13: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1472 qdisc fq_codel state UNKNOWN group default qlen 500
    link/none 
    inet 10.0.1.2/24 scope global tun0

    inet6 fe80::9971:42bb:d660:fd84/64 scope link flags 800 
       valid_lft forever preferred_lft forever

what am I doing wrong here?

note: strangely enought if I try: sudo ssh -D 4444 root@serverip I get prompted for password when I set on server to never ask for that...

# cat /etc/ssh/sshd_config|grep Password
PermitEmptyPasswords no
PasswordAuthentication no

This is another issue but can also be related, sometimes when I press ctrl+c I get this on server side
[DEBUG] Read ICMP packet with src: 10.0.0.29, dest: 10.0.0.12, payload_size: 24, payload: x��� or [DEBUG] Read ICMP packet with src: 10.0.0.29, dest: 10.0.0.12, payload_size: 24, payload: '��D�#�@xxxxxxxxxxxxxxxx�� pls give me some hint, thanks!

I'm really sorry I cannot help you right now since I'm tied up a lot these days :/

the weird chars there look like memory corruption to me... there's a bug in the code somewhere.. maybe you can find it by compiling the code with ubsan and asan activated
