SILC - Secure Internet Live Conferencing ======================================== SILC (Secure Internet Live Conferencing) is a modern and secure conferencing protocol. Features ======== SILC provides all the common conferencing services like private messages, instant messages, channels and groups, and video and audio conferencing. The main difference to other protocols is that SILC has been designed with security as its main feature - it is not an add-on or optional plugin - and security cannot be turned off. All SILC connections execute SILC Key Exchange protocol, an authenticated Diffie-Hellman key exchange algorithm, to generate a shared secret session key. All SILC packets exchanged between SILC clients and servers are protected with these keys. All private messages (instant messages) are protected with private message keys established using the SILC Key Exchange protocol over the SILC network. Private messages can be read only by the sender and the recipient of the message. SILC servers along the way cannot decrypt the messages. Optionally, private message key may also be a shared secret, such as passphrase, or the SILC Key Exchange may be performed peer-to-peer between clients. If all these methods fail the session keys are used as the last resort fallback to encrypt private messages. All channel and group messages are protected with channel specific keys generated by the SILC routers and only the members of the channel may read the messages. Optionally, channel members may set up a shared secret, such as passphrase, as the channel key to exclude SILC routers from knowing the key. Running SILC ============ After installing the SILC to the system the SILC client is started by giving command: silc If you want to run with specific configuration file give -f option. To run the server you should configure the server first. To run the server give the command: silcd This will launch the server on to the background. History ======= SILC was developed between 1996 and 1999 and released to public in 2000. SILC was originally developed by Pekka Riikonen. Contact ======= Feedback and comments are welcome. Bug reports should be sent to the development mailing list.

The 1.1.11 tarball has no README.MACOSX in the top-level directory, this leads to:
Making install in doc
make install-data-hook
mkdir -p /home/estan/silc-client/share/doc/silc-client
/usr/bin/install -c -m 644 ../doc/FAQ /home/estan/silc-client/share/doc/silc-client/

/usr/bin/install -c -m 644 ../README.MACOSX /home/estan/silc-client/share/doc/silc-client/
install: ../README.MACOSX: No such file or directory
Since it's specified in doc/Makefile.am.
Not sure if README.MACOSX should be added to the tarball, or the install command removed.
Add the SILC Client to the Fedora repository.
I tried compiling the latest version on openSuSE 12.2 with the following command line:
./configure --with-silc-plugin=/usr/lib64/irssi --enable-ipv6 --sbindir=/sbin -sysconfdir=/etc --mandir=/usr/share/man --bindir=/bin --localstatedir=/var --prefix=/usr
This completed with the following output:

After running make, I get the following error:

I can provide more logs if required.
Is there something missing from my irssi install?
If I run configure without the "--with-silc-plugin=/usr/lib64/irssi", it compiles successfully.
irssi is version 0.8.15 (which comes with openSuSE).
Thank you,
Chewie
If I am not mistaken, only certain precompiled binaries of pidgin come with the support for SILC, while many linux distros dropped the default support for it (since it requires the silc toolkit). Is it possible to refactor the silc protocol support into a separate plugin (so it can be compiled separately and made available on demand, under the assumption the toolkit is available)?
I don't quite understand the workflow here, in git world, master should reflect the changes as well, but the last commit there was from 2008. I could see 1.1x branch as default, but it's still confusing.
Any plan to merge back to master?
Meanwhile when is it possible to see seperate repo and releases of client, server and toolkit instead of a jumbo repo?
Is there a missing configure.in file at top level?
I know this defeats the purpose of encrypted communication. But it would help to bring some users in and those who are on silc could communicated encrypted with each other already.
Not sure if it's worth the effort, but our matrix bridge is annoying and people want something that's encrypted in the long run, but nothing that requires a webbrowser or a special client that's not CLI.
When trying to start silcd
the following error shows up and the server exits:
