Hello, I am puzzled by this one : Performing a ssh-keyscan from an SL4.5 i368 server to retrieve the RSA key of a newly installed server in SL5.3 x86_64 does not return the right RSA public key. It works between SL4.5 servers. Command : machine-sl4> /usr/bin/ssh-keyscan -t rsa machine-sl5 machine-sl4 : --------------- lsb_release -a LSB Version: :core-3.0-ia32:core-3.0-noarch:graphics-3.0-ia32:graphics-3.0-noarch Distributor ID: ScientificSL Description: Scientific Linux SL release 4.5 (Beryllium) Release: 4.5 Codename: Beryllium openssh-clients-3.9p1-11.el4_7 machine-sl5 : ------------ lsb_release -a LSB Version: :core-3.1-amd64:core-3.1-noarch:graphics-3.1-amd64:graphics-3.1-noarch Distributor ID: ScientificSL Description: Scientific Linux SL release 5.3 (Boron) Release: 5.3 Codename: Boron openssh-server-4.3p2-29.el5 Any idea ?
