[Bug]: DNS and general networking problems
Closed this issue · 6 comments
Problem description
Networking and in general, any application that needs to make a network requests hangs/fail.
Ex: curl google.com
-> DNS cannot be resolved.
Ex: pip
-> Install any package, it does not seem to work, and just hangs.
Ex: openssl
-> openssl s_client hangs
I have looked at #196 [hosts and resolv.conf file exists on my system, it still fails], and #6 [tried everything, still does not work].
The packages installed [using apt after installing glibc-repo] were glibc-runner, openssl-glibc, python-pip-glibc, libcurl-glibc and none of their static libs.
I am wondering if this is a bug or something with my machine setup.

Run the following command to make sure that you have all the files to work with the Internet:
ls -l /data/data/com.termux/files/usr/glibc/etc/hosts
ls -l /data/data/com.termux/files/usr/glibc/etc/resolv.conf
ls -l /data/data/com.termux/files/usr/glibc/etc/ssl/cert.pem
llrwxrwxrwx 1 u0_a370 u0_a370 57 May 18 04:26 /data/data/com.termux/files/usr/glibc/etc/hosts -> /data/data/com.termux/files/usr/etc/hosts
lrwxrwxrwx 1 u0_a370 u0_a370 47 May 18 04:07 /data/data/com.termux/files/usr/glibc/etc/resolv.conf -> /data/data/com.termux/files/usr/etc/resolv.conf
lrwxrwxrwx 1 u0_a370 u0_a370 29 Apr 25 15:44 /data/data/com.termux/files/usr/glibc/etc/ssl/cert.pem -> ../ca-certificates/cacert.pem
They all seem to be symlinked to system files, and system's curl, pip, and internet seem to work just fine.
Run the following command and then upload the glibc-runner-debug-strace-*.log file:
grun -d 4 -n curl google.com
I didn't find anything in the log that could indicate an error. Please make sure you have the following file installed by the resolv-conf package:
/data/data/com.termux/files/usr/etc/resolv.conf
Ok, so I checked my resolv.conf file, and it seems the problem was the down DNS servers listed. I forgot that updating the DNS on Android does not update the resolv.conf file on Termux.
After changing the DNS servers to the correct, updated IPs, it seemed to work.
However, I do wonder why Termux (mine and a docker Termux I was testing) in standard environment was working with non-functional resolv.conf servers but the glibc environment failed, though this may be for a different topic/issue.
