[Solved] Let's Encrypt dehydrated lighttpd 1.4.53
Added by Shrike almost 6 years ago
Hello.
I am trying to use/install Lets Encrypt bootstrap using TLS-ALPN-01 verification challenge and dehydrated (with lighttpd 1.4.53)
As posted on the wiki. /wiki/HowToSimpleSSL
but im running in to a problem.
All goes well until I run the command below
./dehydrated -d www.mydomain.org -t tls-alpn-01 --out /etc/lighttpd/certs --alpn /etc/lighttpd/dehydrated/tls-alpn-01 -c -x
the return result gives this error .

Any help appreciated.
Step 1: consider providing basic information such as your lighttpd.conf and any messages from the lighttpd error log.
Step 2: I wrote HowToSimpleSSL after running exactly those steps, so you should verify in detail that you have followed the steps as written.
"detail": "remote error: tls: no application protocol",
Do you have lighttpd set up to serve TLS on port 443?
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by Shrike almost 6 years ago
I have posted my lighttpd.conf here
http://www.shrike.tk/pub/lighttpd.conf
"Do you have lighttpd set up to serve TLS on port 443?"
yea um i have it configured as instructed as on the wiki,
It does work as https as unauthorized.
When I (re)start Lighttpd the error log only reports
"2019-02-18 00:49:18: (server.c.2059) server stopped by UID = 0 PID = 4433
2019-02-18 00:49:20: (server.c.1464) server started (lighttpd/1.4.53)"
but that's is with the self signed keys.. as instructed just the step before in the wiki page.
.
If i can provide more info let me know .
Best regards, Shrike.
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by Shrike almost 6 years ago
are there any other dependencies i should meet.?
I have lighttpd -v
lighttpd/1.4.53 (ssl) - a light and fast webserver
Openssl 1.1.1a
GnuTLS-3.5.19
Im running LFS (linux from scratch) 8.3
with openssl and lighttpd updated to newest versions.
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by Shrike almost 6 years ago
Oh forgot ...
I have these modules enabled
/etc/lighttpd/modules.conf
server.modules = ( "mod_access", "mod_alias", # "mod_auth", # "mod_evasive", "mod_redirect", "mod_rewrite", "mod_openssl", # "mod_setenv", # "mod_usertrack", )
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by Shrike almost 6 years ago

"mod_rewrite",
"mod_openssl",
)

RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by gstrauss almost 6 years ago
Are you behind a NAT or other firewall that would prevent Let's Encrypt from reaching your site after a DNS lookup of the site?
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by Shrike almost 6 years ago
I traced the iptables log... nothings gets blocked.
and everything gets DMZ-ed to the server.
I even tried it with Iptables turned off. (allow everything)
but when iptables is on the DNS port is open to/from the server.
I have this feeling it's something "small" but it just eludes me...
I have tripple checked everything and started from scratch 3 times.
it just the last step.
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by gstrauss almost 6 years ago
Would you verify that the directories exist?
/etc/lighttpd/dehydrated/tls-alpn-01/
/etc/lighttpd/certs/www.shrike.tk/
Try running ldd on the lighttpd binary and on mod_openssl.so and ensure that they are linked against openssl libs, not GnuTLS.
You probably want to test with Let's Encrypt staging environment https://letsencrypt.org/docs/staging-environment/ with dehydrated so that you don't get blocked by the main server for too many tries.
Try strace on lighttpd during a run of dehydrated and see if lighttpd attempts to read anything from /etc/lighttpd/dehydrated/tls-alpn-01/
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by Shrike almost 6 years ago
/etc/lighttpd/dehydrated/tls-alpn-01/
exists as empty directory
/etc/lighttpd/certs/www.shrike.tk/
exists and holds the pem files.
I'll post back when I have more info.
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by Shrike almost 6 years ago
strace log and ldd output in link below
http://www.shrike.tk/pub/debug.txt
no linkages to GnuTLS
----
openat(AT_FDCWD, "/etc/lighttpd/dehydrated/tls-alpn-01/www.shrike.tk.crt.pem", O_RDONLY) = -1 EACCES (Permission denied)
----
thats a bit troubling.
I have given the directory full access to lighttpd (user www)
and chmod it to 776. (even tried 777)
Im running the dehydrated command as root.
So there 'should' be no Permission denied..

Yes, that would be why lighttpd is unable to serve the certificate to pass the challenge.
You should run dehydrated as the same user under which lighttpd is running. It does not have to run privileged as root. If lighttpd drops privileges to a user other than root, lighttpd will need to be able to read the cert files as this other user. Make sure that dehydrated is writing files with permissions that can be read by the user that lighttpd is running as.
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by Shrike almost 6 years ago
Success. well almost.
I found the problem.
the user "www" for lighttpd did not have a login shell .ie /bin/bash
Now using the non staging CA.
I get a successful dehydrate response.

how ever after i restart lighttpd.
I get a "Secure Connection Failed" when i got to https://www.shrike.tk

RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by gstrauss almost 6 years ago
openssl s_client -connect www.shrike.tk:443
connects to your site, but is immediately disconnected.
See #2912 and the patch in commit 7a7f4f98
Are you sure you're using lighttpd 1.4.53? The above patch was in lighttpd 1.4.51.
If you're using lighttpd 1.4.53, check your cipher list (comment it out and test).
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by Shrike almost 6 years ago
yes Lighttpd -V

And restarted lighttpd. (and rebooted the whole machine)
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by Shrike almost 6 years ago
note...
with the self signed keys.
I could add the security exception in firefox.
so the mod-openssl does work the the self signed.
but not with the signed from lets encrypt.
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by gstrauss almost 6 years ago
I have a Let's Encrypt cert on a test site of mine, and the config works with lighttpd 1.4.53.
server.document-root = "/home/xxxxx/web/www.example.com/"
server.bind = "0.0.0.0"
server.port = 8080
mimetype.assign = (".txt" => "text/plain")
server.modules += ("mod_openssl")
server.modules += ("mod_setenv")
setenv.add-response-header = (
"Strict-Transport-Security" => "max-age=63072000; includeSubDomains; preload",
"X-Frame-Options" => "DENY",

}
This test system is running Fedora Linux 29. You mentioned that you're running Linux From Scratch. That's fine, but would you consider testing on another system? There is something amiss that I can connect to www.shrike.tk port 443, negotiate and get your cert, but then your server disconnects before I can make an HTTP request. Have you tested using the openssl s_client command I provided further above, and looked at the result in the lighttpd error log?
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by Shrike almost 6 years ago
im willing to try that...
i still have a fedora 27 dual boot that i used as a staging to compile from scratch.
I did try the opensll s-client.. after i did that command nothing showed/happened in console for a minute then i pressed Ctrl-C
whats this mod do ?
server.modules += ("mod_setenv")
do i need it ?
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by Shrike almost 6 years ago
as aside note.
Im willing to try everything.
when this turns out to be success full im going to write an article about the pitfalls for an LFS user.
And i will try to have the BLFS team include Lighty as a option to install besides the apache.
Im using lighty my self for years just not the ssl/https.
and certbot does not work for LFS users.
certbot just exits with a message "sorry unknown OS and/or Web server "
certbot is to automated and reliant on Distros/apache
Im kinda a lighty fan. :-)

It handles the encryption and gives you a prompt. Try typing a request. e.g.
GET /index.html HTTP/1.0
(include a second "Enter" at the end of the request)
The mod_setenv stuff is recommended, and comes from https://cipherli.st/ , but is not required.
If openssl s_client works for you connecting from localhost, then try from a remote system.
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by Shrike almost 6 years ago
nothing happens when i enter "GET /index.html HTTP/1.0"
ohh but i entered the command from the same machine ..
Im working from a Windows SSH connection into my server. putty
i'll try upgrading to F29 tomorrow and set every thing up from there.
will take awhile . day job and such.
RE: Let's Encrypt dehydrated lighttpd 1.4.53 - Added by gstrauss almost 6 years ago
Just to be clear, when running openssl s_client ..., at the point where it "hangs", that is where it is waiting for you type type the request and press Enter twice.
Before you update to F29, you might copy the certs over to your F27. If you compile lighttpd there, you can try running with the Let's Encrypt certs.

[Solved]
I compiled a new kernel 4.20.10 with crypto options listed below.
Then i recompiled Lighttp 1.4.53
Now it works.
Im not sure which kernel options are the ones necessary.
A lot of the options where already on. but i turned on some more.
Thank you kindly good Sir for your support, time, effort and patience.
