Summary0011629: can't bootstrap
DescriptionHi,
I'm testing gnunet on gentoo, I did build it from source, started "gnunet-arm -s" checked that services are available with "gnunet-arm -I"
so after I wanted to check if I was connected, so I done a "gnunet-gns -u gnunet.gns.alt" and it wait... wait... wait... and never timeout
so I done some wireshark capture to see if there was some firewall/NAT issue... and... nothing.... just regular ICMP some unrelated UDP trafic.

gnunet-config -s gns t
.gnunet.gns.alt = 000G0522TTKQESZ9KPRT2K0RA9ZC8YMD52D2XYVYVGPDCNPMWHH9QXXF4W
.pin.gns.alt = 000G0522TTKQESZ9KPRT2K0RA9ZC8YMD52D2XYVYVGPDCNPMWHH9QXXF4W
INTERCEPT_DNS = NO
MAX_PARALLEL_BACKGROUND_QUERIES = 1000
UNIX_MATCH_GID = YES
UNIX_MATCH_UID = NO
UNIXPATH = $GNUNET_RUNTIME_DIR/gnunet-service-gns.sock
BINARY = gnunet-service-gns
HOSTNAME = localhost
IMMEDIATE_START = YES
START_ON_DEMAND = YES

I wonder what is wrong....

I need to investigate this, testing via GNS is probably not helpful, first it must be verified that you are actually connected and bootstrap via hostlist server(s) works. It is likely that due to recent urgent server updates the bootstrap peer is/was down for a prolonged period of time.

Hi, how can I help investigating?
there is no "troubleshoot" section in https://docs.gnunet.org/latest/users/start.html
if testing via GNS is not helpful what is the best way to see if the system is connected (seeing that the system is up is in the above docs)

pardon my ignorance, but I thought that gnunet rely on GNS and that without GNS, since we can't resolv hosts, there is no way to connect to the network.... are the bootstrap ip hardcoded?

GNUnet does not rely on GNS for bootstrapping. GNUnet needs so-called HELLO messages. A HELLO contains the Peer ID (public key) and a set of (signed) endpoints it can be reached at (e.g. TCP/IP addresses). Every installation ships with a single HELLO for our bootstrap peer. The bootstrap peer also collects known HELLOs of connecting peers and publishes them through a hostlist. Each client in its default configuration reads this hostlist and tries to connect to peers.

To check which peers are connected or your peer attempts to connect you can use the "gnunet-core" cli tool. For example "gnunet-core -m"

maybe that's my issue? is there a bootstrap peer file? maybe it wasn't installed?
will try the "gnunet-core -m" as soon as possible

The bootstrap file is downloaded via HTTP. Your problem likely was that our bootstrap peer was not running. I have restarted it the other day.

I just tested connecting with v0.28.0 and it seems we have a regression in our handshake crypto :( I will need to track down that bug fist I guess.

how can I re-download the file?(automatic or manually) maybe this should be added into installation documentation

You do not have to redownload anything. it is downloaded on ever new start of the peer and then regularly.

I found the regression and it works again (with git master HEAD).
On gnunet-core, the server outputs something like

Mon Jul 20 14:36:51 2026: Hello sent (I) PBM3 (timeout in 0 ms)
Mon Jul 20 14:36:51 2026: Done sent (I) PBM3 (timeout in 0 ms)
Mon Jul 20 14:36:51 2026: Done sent (I) PBM3 (timeout in 299 s)
Mon Jul 20 14:36:51 2026: Connected (I) PBM3 (timeout in 299 s)
Mon Jul 20 14:36:57 2026: Connected (I) PBM3 (timeout in 299 s)
Mon Jul 20 14:37:05 2026: Connected (I) PBM3 (timeout in 299 s)

For your client, you will probably only see the last line because it will have happened too fast, otherwise it will be stuck in any state above.
But you will have to upgrade first. Also, sometimes the bootstrap peer hangs, but that is an unrelated issue :/

ok I updated the ebuild to build the git version
gnunet compiled fine, but I can't start the service because it now complain

 * You must create /etc/gnunetd.conf file first
 * ERROR: gnunet failed to start

searched the web, it seems that this file can only be created using gnunet-setup that is a tool provided by gnunet-gtk package.... but... latest gnunet-gtk package is 0.24.0 according to what is in https://ftp.gnu.org/gnu/gnunet/ and this source don't compile with the git head....

lot error complaining about GNUNET_CRYPTO_PublicKey not defined...

In file included from ../gnunet-gtk-9999/src/fs/gnunet-fs-gtk_main-window-connection.c:27:

how can I create a /etc/gnunetd.conf by hand?

note : I used the git head of gnunet-gtk, not the 0.24.0

searching the web, it seems that /etc/gnunetd.conf is the old name of /etc/gnunet.conf

so I tried to simply symlink the files
so content of both files is

# cat /etc/gnunetd.conf
[arm]
START_SYSTEM_SERVICES = YES
START_USER_SERVICES = NO


started the service, tried gnunet-arm -I and now I have lot of fails...

# gnunet-arm -I

hopefully there are something in syslog
