tun2socks - Assertion failed - ASSERT(client->socks_send_prev_buf_used > 0) #1

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. ssh -D 1234 user@server
2. openvpn --mktun --dev tun0 --user root
3. /sbin/ip addr add 10.0.0.1/24 dev tun0
4. route add server gw 10.0.5.1 metric 5
5. route add default gw 10.0.0.2 metric 6
6. delete default gw 10.0.5.1
7. ifconfig tun0 up
8. ./badvpn-tun2socks --tundev tun0 --netif-ipaddr 10.0.0.2 --netif-netmask 
255.255.255.0 --socks-server-addr 127.0.0.1:1234
9. Go to http://speedtest.net/ under Firefox 4.0 wait for upload test... then 
tun2socks should assert.

What is the expected output? What do you see instead?

/home/thireus/Bureau/badvpn-1.999.105.1/tun2socks/tun2socks.c:1160 Assertion 
failed
Abandon

What version of the product are you using? On what operating system?

badvpn-1.999.105.1.tar.bz2
2.6.35-28-generic Ubuntu x86_64 GNU/Linux

Please provide any additional information below.

Assertion failed happens everytime it tries to make the upload test :/ There's 
something wrong with buffering :s

Thank you for reporting this bug. I'm sorry about that; something strange must 
have been going through my head :)
