I can't reproduce it on my machine.

You may check the graftcp-local log, or check the proxy server is working.

not sure if it was related with the GFW. i have installed a squid http proxy server in aws us-west-2 region, then used graftcp in shanghai local machine to pull gcr images. Also failed pulling gcr images with ss proxy. have any suggestions?

You may check the proxy server is working: curl -x http://my_proxy:3128 http://www.google.com/.

hi, looks like find the root cause, actullay i run graftcp-local service in a docker container, in a gitlab runner with a docker container. meanwile the ss5 server didn't get the requests log. but mgraftcp is ok. so another question: does graftcp-local work in container?

Are graftcp and graftcp-local in the same container? They communicate using named pipes, and graftcp-local needs to access /proc to determine information related to graftcp. They need to be in the same environment to work properly.

yes, they were in same container.

1. graftcp-local service issue got fixed, the parameter -config does not work, it always use default configuration in /etc/graftcp-local/graftcp-local.conf.
2. on ubuntu system systemd-resolved service listen tcp 127.0.0.53:53 port to resolve dns, and aws ec2 also have a internal dns service, i added these 2 IPs into graftcp parameter --blackip-file to ignore them. like 10.16.0.2 127.0.0.53

[freidenker]

and graftcp bash still not work in docker container

1. How do you start graftcp-local service? If it run as a service, please check the it's systemd-unit service conf.
2. This tool does not have the ability to affect the dns.

Please check if your docker supports ptrace.

graftcp-local -service install & graftcp-local -service start. right, systemd-unit service conf is always /etc/graftcp-local/graftcp-local.conf.

Please check if your docker supports ptrace.

for GitLab CICD pipeline, we can define that image's Dockerfile to implement graftcp bash. ENTRYPOINT ["/bin/bash", "-c", "graftcp-local -service start; /opt/graftcp-blackip.sh; graftcp --blackip-file=/opt/blackips bash"]

just changed the issues title, to the users of graftcp with similar issues.

thanks @hmgle for your help. the --blackip-file looks does not support CIDR, right?
