troglobit / inadyn Goto Github PK

Hey, could you create tags for the new releases? It would be nice to have GitHub create tarballs for them.

Using inadyn 1.99.9 (and 1.98.1 before that), I recently changed my DynDNS password. The newly generated pw had a backslash in it (more precisely a backslash followed by an equal sign).
The credentials were stored in a configuration file for inadyn.
inadyn seems to strip the backslash character from the password, making it shorter than it actually is.
This results in the wrong base64 string being calculated.

Interestingly, with the unmodified version if inadyn, the DynDNS server would always reply with "good 127.0.0.1", and the host would not be updated.
Playing around with the User-Agent string, I'd only then get "badauth" responses from members.dyndns.org.

The release tarball is a bit too small to contain any useful data:

$ ls -l inadyn-1.99.9.tar.xz*
-rw-r--r-- 1 ralf ralf 32 May 21 18:49 inadyn-1.99.9.tar.xz
-rw-r--r-- 1 ralf ralf 55 May 21 18:49 inadyn-1.99.9.tar.xz.md5

The md5sum is correct though :-)

Original multi-platform goal is no longer the goal of the current maintainers.

• Primary target is Linux based systems, home routers, etc.
• Secondary target is other UNIX based systems, *BSD, Solaris etc.

Hi,

I've got a DDNS provider here that expects username, password and IP in the server url, e.g.
/ddns.php?user=myname&password=mypass&ip=1.2.3.4

So it would be nice if it could be configured like this in the config file
server-url /ddns.php?user=<username>&password=<pass>&ip=<ipaddr>
and <username>, <pass> and <ipaddr> will be replaced with the actual values.

• simplify
• Simplify
• SIMPLIFY

Too complex and difficult to both maintain and even to get
an overview of.

Is it possible to add LibreSSL support too?
http://www.libressl.org/

Refactor current inadyn_cmd.c & c:o into a simpler conf file parser, e.g., conf.c and
a much shorter command line parser, using getopt_long() directly in main().

Command line options should be:

• -h,--help
• -d,--debug=LVL
• -l, --syslog
• -L, --logfile=FILE
• -V,--verbose
• -v,--version
• -n,--foreground
• -1, --once
• -t, --startup-delay=SEC
• -p,--drop-privs=USR[:GRP]
• -f,--config=FILE

All remaining CLI options can be specified in the config only. When the config option is not given on command line, inadyn should check first the system-wide config /etc/inadyn.conf, if that doesn't exist, check user config in the home dir: $HOME/.inadynrc, or $HOME/.config/inadyn.conf

it does not submit the servername, so it might talk to some "default" server on same IP (that may also have a different certificate). i noticed it when it didn't log the correct server name after my last fix. somehow it works though, so it seems to get wrong certs, but correct server... (no idea how that can be).

i am working on a fix, at least for openssl (for gnutls there seem to be linktime issues with my current work):

/usr/bin/ld: src/ssl.o: undefined reference to symbol 'gnutls_server_name_set@@GNUTLS_1_4'

Any clue ? A lot of thanks

The timeout arg to setsockopt(...,SO_RCVTIMEO/SO_SNDTIMEO)
should be a struct timeval, not an integer number of milliseconds, which is
what is done in inadyn-1.97.1 (and all previous versions I've seen).

Perhaps passing a pointer to int works, because one also passes the size, and
setsockopt may have some backward compatible code. Seems wise to update it to a
struct timeval though. Here's a patch:

I was having problem with the original inadyn giving RC_IP_CONNECT_FAILED using dyndns service. After reading your post http://www.dyndnscommunity.com/questions/6318/rc-ip-connect-failed/6323, I try your inadyn version and this issue is still there but with a different error message. Here is the output of the log file:

Fri Oct 29 07:15:56 2010: Started 'INADYN version 1.97.1' - dynamic DNS updater.
Fri Oct 29 07:15:57 2010: Error 11 when resolving host name checkip.dyndns.org: Resource temporarily unavailable

Only when I restart inadyn service, then it is able to resolve checkip.dyndns.com using the other ip addresses.

Hi,

it would be great if the multiservices patches mentioned at the following sites was integrated:

http://sourceforge.net/p/inadyn-mt/patches/4/
http://sourceforge.net/p/inadyn-mt/feature-requests/2/

As the title says, the configure script doesn't recognize that openssl 1.0.1f is already installed on my ubuntu 15.04 system

As mentioned by Mike Fleetwood in pull request #42 regarding the problem with bootup on
embedded devices w/o battery backed up RTC's:

However if inadyn waited for a while on startup before doing anything
it is likely the IP address and time will have been set. Make it an option
--startup-delay SEC, with a default of 0. Desktops and other devices
with a battery backed RTC take the default, devices without can set it.
Optionally make SIGHUP end the startup delay early in case setting
the time from NTP wants to trigger a check immediately. In fact all
signals will end the delay, but the others will stop inadyn too.

(This is similar to the keepalived preemp_delay [0-300] setting.)

After initial start, before reading the cache file, inadyn will sleep for the
given number of "startup delay" seconds. Any signal will wake it up,
but it is recommended to use SIGUSR1 from #43, since SIGHUP is
reserved for reloading inadyn.conf

As suggested by Mike Fleetwood in pull request #42

I'd love to see the Forced Update event set the IP to a random value and immediately set again to actual value. This circumvents silly free DDNS providers who do not consider an update with an unchanged IP address to actual be an update. Simply put, DDNS providers who expire free hosts addresses after an inactivity threshold punish users who's address remain constant for long periods of time and reward those who's change frequently.

Hello,

I wrote a patch to change behaviour of --change_persona option to accept username and groupname instead of their numeric IDs. Please take a look. My C experience is not very well.
Thanks.

Not sure, didn't quickly find it in the docs: is inadyn already sending such updates?
If not, please implement, helps free dyndns services to keep their databases slim and clean.

When inadyn fails to connect to the remote server it should not restart the timers with the configured period and forced-update interval.

Andy Padavan of the ASUS RT-N56U custom firmware project reports that the inadyn.conf parser treats '#' in data fields, e.g. passwords, as comments (to end of line).

The fix is to force users to start inline-comments with a space.

For reference, see:
https://code.google.com/p/rt-n56u/source/detail?r=353e368e9f3fd8543340e60968e893c59920f42b

Currently the cache file contains only the first host name.
What if we want to update multiple host entrys?

Possibly use:

    my.first.host.tld.cache
    another.host.tld.cache
    etc.tld.cache
    inadyn.pid

Hi

When my Internet Provider change my IP address, it is never update on the FreeDNS.afraid.org. I always have the message "Update URL query failed" from the inadyn. When I log to the site freedns.afraid.org and go under the "Dynamic DNS", if I click to the button "Direct URL", my IP address is updated. Do I mist something in my config file? Do you have any idea what is the problem?

I am running inadyn version 1.99.9 under Debian 7.

This is my config file:
username MyEmailAddress
password MyPassword
system [email protected]
alias mahingan.homenet.org
ssl
log_file /var/log/inadyn.log
period 600
background
verbose 5

This is the log I got:
Mon Jun 8 20:12:57 2015: Inadyn version 1.99.9 -- Dynamic DNS update client.

How can I set it up to preferably use an IPv6 address rather than IPv4? Does inadyn even support IPv6? I'm using Dyn, which gives me the possibility of entering IPv4 and IPv6 addresses.

First of all I would like to thank you for investing your time in working on an open source project such as this. Second, I would like to comment some issues I have detected when updating inadyn to one of its most recent versions.

For the 1.99.4 version, on a Debian Jessie.

When running inadyn specifying a custom service with inadyn -S custom@http_svr_basic_auth (as seen in the manpage) the following error shows up:

Fri May 8 12:37:58 2015: Cannot find DDNS provider custom@http_svr_basic_auth, check your spelling.
Fri May 8 12:37:58 2015: Error parsing option -S
Fri May 8 12:37:58 2015: Failed starting daemon: >RC_CMD_PARSER_INVALID_OPTION_ARGUMENT

However, when running with inadyn -S custom@http_srv_basic_auth (notice svr changed to srv), I don't get this error anymore.

Another issue is that, when specifying a custom service, I am forced to specify a username and a password, otherwise I get this error:

Fri May 8 13:21:05 2015: Missing username in account 1
Fri May 8 13:21:05 2015: Missing password in account 1
Fri May 8 13:21:05 2015: No valid DDNS setup exists.
Fri May 8 13:21:05 2015: Failed starting daemon: >RC_DYNDNS_INVALID_OR_MISSING_PARAMETERS

I shouldn't need to specify neither username nor password as, in this case, they are passed to the server directly in the URL (using -U flag). Specifying those wasn't required in previous versions.

Something similar happens with the alias, I am forced to specify one even though the hostname should be passed through the URL in the same way as the username or the password. However, this did happen in previous versions.

At last, when running inadyn using this workaround (replacing those required parameters with random words or empty strings):

inadyn -S custom@http_srv_basic_auth -N dynamicdns.park-your-domain.com -U "/update?domain=my.domain&password=mypassword&host=myhostname" -u user -p password -a ""

The IP is successfully updated in the server. However, the inadyn daemon reports the following error and stops running:

Fri May 8 14:54:30 2015: Failed resolving hostname : Name or service not known
[...]
Fri May 8 14:54:31 2015: Fatal error in DDNS server response:
Fri May 8 14:54:31 2015: [200 OK] SETDNSHOSTengMy IP :)00true
Fri May 8 14:54:31 2015: Error response from DDNS server, exiting!
Fri May 8 14:54:31 2015: Failed starting daemon: RC_DYNDNS_RSP_NOTOK

It is logical that it fails resolving the hostname as there is no hostname (empty string) but I belive it shouldn't be reporting a fatal error on the sever response when the response contains <ErrCount>0</ErrCount>.

This last issue makes the daemon unusable when it comes to custom services, and a Cron job or another alternative needs to be configured.

It would be nice if those issues could be solved, otherwise I think that the 'custom service' feature would not be fully functional. Thank you for your time!

Create a simple plugin system, e.g., like how troglobit/finit does it and let all DDNS providers be plugins.

Hi,
whenever inadyn updates my IP at twodns.de it quits throwing an error message although the IP got updated:

I already tried the versions 1.99.4 to 1.99.6.
Any help is appreciated. Thx!

Greg Keefe wrote to request support for his free DDNS provider hn.org in Inadyn.

The protocol for hn.org is defined here http://hn.org/hnRFC10.txt and uses POST instead of GET, so for this to work the implementer need to first add support for POST to Inadyn.

The environment variables are useless.

IP, and any other information, should instead be be read from the cache file.

thanks

Even when I've had an invalid update (see issue #19), my IP gets cached. I would have thought that it should only get cached on success?

Remove configurations support for custom pidfile. This to remove inhouse code in favor of the standard OpenBSD functions.

HTTPS support, possibly using a tiny library like PolarSSL, from which the
current md5 & sha1 implementations are from.

Probably best implemented after #30 is done.

The inadyn template "[email protected]" for ipv4.tunnelbroker.net is wrong. See the reference documentation at https://forums.he.net/index.php?topic=1994.0

Mon Mar 30 10:17:15 2015: Current public IP# xxx.xx.xxx.xxx

The correct update URL should instead be:

https://<USERNAME>:<PASSWORD>@ipv4.tunnelbroker.net/nic/update?hostname=<TUNNEL_ID>

e.g.

https://ipv4.tunnelbroker.net/nic/update?username=<USERNAME>&password=PASSWORD>&hostname=<TUNNEL_ID>

Please fix with add an --system "[email protected]" , using dyndns 2 prokoll with the correct URL (given by he.net wiki)

I just found a nasty bug. On first start, when there does not exist any cache of
what IP we've successfully sent to our DDNS provider, inadyn creates the cache
file anyway ... regardless if the first update succeeds or not.

At Westermo we noticed this due to reports from several users complaining about
odd out-of-sync DNS and inadyn logs reporting no change:

May 15 07:03:26 falcon inadyn[559]: Inadyn version 1.98.0 -- Dynamic DNS update client.
May 15 07:03:26 falcon inadyn[559]: Resolving hostname grodblad.dyndns.org => IP# 217.208.26.40

May 15 07:03:27 falcon inadyn[559]: Sending IP# update to DDNS server, connecting to members.dyndns.org(204.13.248.111)
May 15 07:03:27 falcon inadyn[559]: Failed connecting to remote server: Interrupted system call
May 15 07:03:27 falcon inadyn[559]: RESTART command received. Restarting.
May 15 07:03:27 falcon inadyn[559]: Inadyn version 1.98.0 -- Dynamic DNS update client.
May 15 07:03:27 falcon inadyn[559]: Cached IP# 217.208.24.147 from previous invocation.
May 15 07:03:27 falcon inadyn[559]: Checking for IP# change, connecting to checkip.dyndns.org(216.146.39.70)
May 15 07:03:27 falcon inadyn[559]: No IP# change detected, still at 217.208.24.147

Since inadyn failed connecting to the remote server before the RESTART command it should not update the local cache file. But it does, since the file is missing (?!) and after RESTART the file exists, but the cached IP has not been registered by the DDNS provider ...

Maintainers have agreed that Linux coding style should be used and that the code,
at the same time, should be massively cleaned up.

It would be good if there was a noproxy list like curl supports:

--noproxy <no-proxy-list>
          Comma-separated  list  of hosts which do not use a proxy, if one
          is specified.  The only wildcard is a single * character,  which
          matches all hosts, and effectively disables the proxy. Each name
          in this list is matched as either a domain  which  contains  the
          hostname,  or  the hostname itself. For example, local.com would
          match  local.com,  local.com:80,  and  www.local.com,  but   not
          www.notlocal.com.  (Added in 7.19.4).

Hi,

building version 1.99.13 fails with message "No rule to make target CHANGELOG". You probably have renamed CHANGELOG to ChangeLog and you also have to change this in the Makefile's doc_DATA variable.

Andy Padavan of the ASUS RT-N56U custom firmware project reports that Parsing checkip responses in function parse_my_ip_address() fails when the IP is not found on first iteration, inet_aton() fails. String will be zero-terminated, second iteration reaches '0' and loop exits.

For more details, and patch, see:
https://code.google.com/p/rt-n56u/source/detail?r=4e8092880d71cf4095479b8b8b503237322e5376

Before the Inadyn package can be updated in Debian a GPL exemption for linking against OpenSSL is needed.

• Investigate if permission from other copyright holders is needed
• Investigate alternative libraries for when used in Debian, e.g., GNU TLS

Timur Birsh (Debian Inadyn maintainer) reports:

Would you please add an OpenSSL exception to the inadyn license.
Please see:

https://lists.debian.org/debian-legal/2004/05/msg00595.html
https://people.gnome.org/~markmc/openssl-and-the-gpl

When starting it tries to write to /run/inadyn/inadyn.pid as debian-inadyn, and since it doesn't have permissions it dies. I can not find in the configuration files where I can change this path. I had to change the user in /etc/inadyn.conf to root to get it to run.

Version: 1.99.4-1
Ubuntu 14.04.2

After looking at GnuTLS' OpenSSL compatiblity layer, it somehow left a mediocre impression:

• some essential stuff is missing (see hack for SNI support in inadyn ssl.c)
• some of the implemented API calls are not fully implemented (e.g. does not dynamically allocate a buffer if you give a NULL pointer)
• GnuTLS 3.0.5 NEWS: "gnutls-extra: is no more" - so it was killed in 2011.

So, I think if one wants to support both OpenSSL and GnuTLS, it should be by directly using their native APIs (not: that dead OpenSSL compatibility wrapper).

Currently Inadyn only caches the external IP address. This leads to
some unwanted effects when the IP remains the same but the user
changes to another hostname.

The DNS record will not be updated unless there is an IP address change,
or after the forced-update interval has expired.

Related to issue #34

I successfully compiled inadyn (repo tip of today), it talks http to the get-ip url, it also sends an unencrypted http update to nsupdate.info. So far so good.

But: if i use same configuration and just switch on "ssl" support, it does not successfully send an https update, likely because it does not support SNI (server name indication). The service on https://nsupdate.info requires SNI. Please support this, we are running out of IPv4 since years, so multiple SSL hosts on one IPv4 should be supported.

And make sure it passes the Coverity Scan as well ... -- Joachim @troglobit Nilsson

Neither the inadyn.conf option pidfile nor the command line option --pidfile seems to work on my machine. No pid file will be created although running inadyn as root.

This is somewhere documented even, but I think it deserves a place in the issue tracker also.

The transmission will be still encrypted, but the client is basically not knowing whether it really talks to the right server.
