thanks you very much, quick test failed here now due

after quick look, looks like its due mv resolv.conf ... which is inside the docker enviroment ...

may a way to disable and write manually the dns entries ?

@reback00 Hi,

We can confirm the same issue regarding the

Link: [ERR] Rename of /etc/resolv.conf to /etc/resolv.conf.backup.hide.me failed, device or resource busy

We tried a workaround, to use a flag -b /etc/resolv.conf

And kind of passed

Link: /etc/resolv.conf moved to /etc/resolv.conf
Link: /etc/resolv.conf created

But..eventually, a terminal freezes up :( even though it seems that connection kind of successful by itself

[reback00]

@alturismo Can you test the above to see if it works for you? Also, does the freeze happen?

[alturismo]

@reback00 thanks for the reminder, i take a look at the weekend, now i know what i forgot to test here ;)

[alturismo]

sorry for the late reply, and yes, looking ok, just cant startup in the background

using a new session i see

curl ifconfig.me

91.199.118.73/ #

which should be the hideme vpn ;)

thanks alot

I am experiencing the same problem within a docker container and -b does not work for me.

Main: [ERR] Connection setup/teardown failed, traffic blocked, waiting for a termination signal

Problem persists with or without "-s" arguments. The call to "hide.me -u ... -P ... token streaming-uk" works as expected and an access token file is generated. Also tried to replace the contents of /etc/resolv.conf with "nameserver 8.8.8.8" and/or my local DNS but didn't work either.

Original contents of /etc/resolv.conf:

search homedomain
nameserver 127.0.0.11
options ndots:0

The latest version ( 0.9.2 ) should fix this issue

[NikMAX2077]

same problem in 2023 on v.0.9.2

What's the issue for you, the DNS lookup or terminal freezing ? Terminal freezing might happen if you ssh into a docker container and run hide.me. Our routing setup and the activation of the kill-switch will interrupt your ssh session. A workaround would be to use the -s option.

DNS lookup issues could be solved with -d option. By default, hide.me uses our own DNS servers when looking up hide.me server DNS names. Hide.me CLI does not care about resolv.conf during this stage of the connection setup. You can use -d to set your preferred DNS servers for that part of the connection setup, e.g.:

hide.me -d 9.9.9.9:53 connect nl

After the connection gets established we need to install in-tunnel DNS servers. In order to do that we have to replace resolv.conf. -b option is just about a backup path for the original resolv.conf. Once the connection ends we have to restore resolv.conf to its original state from the backup.

I get the same thing, DPD Starting but nothing is working. It was working for me 6 months ago and now it has stopped working for no reason.
