Dear list, Hopefully someone from jabber.ru is here or someone knows someone there. I was contacted by someone @jabber.ru, but I cannot reply because the DH key size used by their server for TLS is too small to be accepted by the TLS libraries distributed with Debian stable.
Can someone forward this information to them so that they can upgrade their implementation? The minimum DH key size supported is 2048 bits. This is affecting the listing of MUCs on search.jabbercat.org / search.jabber.network since the XMPP server used for that runs on Debian stable and will thus not be able to establish s2s connections to jabber.ru for MUC indexing. You can contact me off-list via E-Mail using the address this E-Mail was sent from (XMPP will probably not work if you’re on jabber.ru due to the issue) if you need more info. (Note that DH key sizes smaller than 2048 have been flagged by xmpp.net for years now, and Debian and others have announced that quite some time ago.) kind regards, Jonas
