This follow-up is not systemd, but I guess that you can help. The rc.d script I have[0] keeps failing with weird errors. Previously it was just https://bugs.gnunet.org/view.php?id=5632, but with this more recent configuration I can not get normal users in group gnunet to start their own gnunet-arm: Mar 11 09:29:46-674528 util-service-321 WARNING `bind' failed for `/tmp/gnunet-ng0-runtime//gnunet-service-arm.sock': address already in use Mar 11 09:29:46-674980 arm-321 ERROR `bind' failed at service.c:1847 with error: Address already in use Mar 11 09:29:46-675072 arm-321 ERROR Could not bind to any of the ports I was supposed to, refusing to run! so /var/chroot/ for gnunet folder: drwx------ 6 gnunet gnunet 1024 Mar 11 09:29 gnunet inside gnunet: drwxr-xr-x 3 gnunet gnunetdns 512 Feb 28 21:34 .cache drwxr-xr-x 3 gnunet gnunetdns 512 Mar 1 10:52 .config drwxr-xr-x 3 gnunet gnunetdns 512 Mar 1 10:52 .local drwxr-xr-x 7 gnunet gnunetdns 512 Mar 11 00:43 data srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-ats.sock srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-cadet.sock srwx------ 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-consensus.sock srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-core.sock srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-datastore.sock srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-dht.sock srwx------ 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-dns.sock srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-fs.sock srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-namecache.sock srwx------ 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-nat-auto.sock srwx------ 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-nat.sock srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-nse.sock srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-peerinfo.sock srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-peerstore.sock srwxrwxrwx 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-regex.sock srwxrwxrwx 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-resolver.sock srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-revocation.sock srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-scalarproduct-alice.sock srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-scalarproduct-bob.sock srwx------ 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-set.sock srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-statistics.sock srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-transport.sock srwxrwx--- 1 gnunet gnunet 0 Mar 11 09:29 gnunet-service-vpn.sock while at least .config and .local are remains from previous configurations. When I did not set GNUNET_DATA_HOME, GNUNET_RUNTIME_DIR, and GNUNET_HOME (so against our own recommendations for distributors ;)) it worked but #5632 occured. perms on /usr/pkg/etc/gnunet and its contained config file: drwxr-xr-x 2 root wheel 512 Mar 10 23:33 gnunet -rw-r--r-- 1 root wheel 1858 Mar 10 23:33 gnunet.conf Is there an obvious mistake somewhere? 0: https://wip.pkgsrc.org/cgi-bin/gitweb.cgi?p=pkgsrc-wip.git;a=tree;f=gnunet;h=f36cec375236bb80d621681d4f958483848be396;hb=HEAD in "files" _______________________________________________ GNUnet-developers mailing list [email protected] https://lists.gnu.org/mailman/listinfo/gnunet-developers
