Hello again, Just answering to myself and the list for a conclusion. lftp in CentOS uses the default priority provided by gnutls and it's not possible to override it in lftp 4.0.9 provided in CentOS 6. Howerver, the ssl:priority feature has been implemented in lftp 4.6.2 (https://github.com/lavv17/lftp/commit/b406805d2b3d4c9a88e24363980e5717e61d0948) and there is also a backport RHEL/CentOS for CentOS 7 (https://git.centos.org/blob/rpms!lftp/373a02466b773fe2dbbfde702aec1848e006ba70/SOURCES!lftp-4.4.8-ssl-tls-restrict.patch) I think it could be nice if that feature could be backported into the CentOS 6 lftp version.
