failed connecting to localhost on port 9002 scheme tcp

ktunnel version 1.2.4 (1.2.5 actually)

my PHPStorm is listening port 9002.

➜  ~ lsof -i :9002
COMMAND    PID USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
phpstorm 50781 cyao  465u  IPv6 0x32e9aa96a4c0d673      0t0  TCP *:pichat (LISTEN)

And I also tried to start a TCP server to respond to the connection.

➜  ~ nc -vl 9002

same error.

Hi @kukat, the ktunnel client attempts to dial to localhost:9002, what happens if you try to netcat/telnet/curl manually? are you able to bind? if so, the client has a 50ms dial timeout and maybe increasing it will solve this.

I've released v1.2.6 that includes the actual error in the log message, could you please use that version and let me know what error the client is showing?

[kukat]

Thanks @omrikiei

still failed with the latest v1.2.6, extra error info:

dial tcp [::1]:9002: i/o timeout

[omrikiei]

I've increased the dial timeout to 500ms in v1.2.7(being released now..). please let me know if it helps

[kukat]

Awesome, 1.2.7 works! Thank you @omrikiei

btw, do you think if it makes sense to add timeout as an argument

[kukat]

also, is there a reconnect strategy? i noticed that if i restart the phpstorm, the connection is dead, i have to quit ktunnel and run ktunnel inject again.

[omrikiei]

Hi @kukat, I'm working on a version that includes the timeout as a cli flag. regarding the reconnect strategy, it shouldn't happen, because on each request a new connection is created to the local machine.. I'll try to reproduce it

[omrikiei]

@kukat I closed and opened phpstorm, and managed to connect with no issue

[omrikiei]

closing issue for now
