Fedora 13 has openssh 5.4p1, which requires to explicitly enable ssh protocol 1: # The default requires explicit activation of protocol 1 #Protocol 2 But rkhunter displays a warning: Warning: The SSH configuration option 'Protocol' has not been set. The default value may be '2,1', to allow the use of protocol version 1. I got an answer in rkhunter mailing list: From the config file: ...If the 'Protocol' option has not been set in the SSH # configuration file, then a value of '2' may be set here in order to # suppress a warning message. So set ALLOW_SSH_PROT_V1=2 in rkhunter.conf.
rkhunter-1.3.6-6.fc13 has been submitted as an update for Fedora 13. http://admin.fedoraproject.org/updates/rkhunter-1.3.6-6.fc13

rkhunter-1.3.6-6.fc13 has been pushed to the Fedora 13 stable repository. If problems still persist, please make note of it in this bug report.
1.3.8-1.fc14 from updates-testing has the setting dropped: -ALLOW_SSH_PROT_V1=2 +ALLOW_SSH_PROT_V1=0 Please use 2 as before. Also I get the new warning: Warning: The SSH configuration option 'PermitRootLogin' has not been set. The default value may be 'yes', to allow root access. But ALLOW_SSH_ROOT_USER=yes has not changed, so this may be a new bug in rkhunter. There are duplicate lines in rkhunter.conf: ALLOWHIDDENFILE=/lib*/.libcrypto.so.*.hmac ALLOWHIDDENFILE=/lib*/.libcrypto.so.*.hmac ALLOWHIDDENFILE=/lib*/.libssl.so.*.hmac ALLOWHIDDENFILE=/lib*/.libssl.so.*.hmac ALLOWHIDDENFILE=/usr/lib*/.libfipscheck.so.*.hmac ALLOWHIDDENFILE=/usr/lib*/.libfipscheck.so.*.hmac apps was removed from DISABLE_TESTS in rkhunter,conf, so I get a new warning: Warning: Application 'sshd', version '5.5p1', is out of date, and possibly a security risk.
That config worked great in rawhide, but of course I failed to test it enough in f13/f14. ;( Thanks for reporting this. Will try and push out updated packages tonight or tomorrow.
I whipped up scratch builds last night. Haven't fully tested them yet.

Again the same problem on F15 :) Compared to F14 rkhunter.conf: -ALLOW_SSH_PROT_V1=2 +ALLOW_SSH_PROT_V1=0 And because of this: Warning: The SSH configuration option 'Protocol' has not been set. The default value may be '2,1', to allow the use of protocol version 1.
ALLOW_SSH_PROT_V1=0 seems to have removed this error for me on Fedora 14 with rkhunter-1.3.8-2.fc14.noarch.
Glenn: 0 fixes your setup? Thats strange... 2 should be the correct value. I don't know why the setting change got dropped in f15/rawhide, but I will push a fixed update...
