SELinux is preventing /usr/sbin/sshd from 'search' accesses on the directory /home/kelvan.

*****  Plugin restorecon (82.4 confidence) suggests  *************************

If you want to fix the label. 
/home/kelvan default label should be user_home_dir_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /home/kelvan

*****  Plugin file (7.05 confidence) suggests  *******************************

If you think this is caused by a badly mislabeled machine.
Then you need to fully relabel.
Do
touch /.autorelabel; reboot

Then you need to fully relabel.
Do
touch /.autorelabel; reboot

*****  Plugin catchall_labels (4.59 confidence) suggests  ********************

If you want to allow sshd to have search access on the kelvan directory
Then you need to change the label on /home/kelvan
Do
# semanage fcontext -a -t FILE_TYPE '/home/kelvan'
where FILE_TYPE is one of the following: user_home_dir_t, tmp_t, tmp_t, usr_t, usr_t, var_t, var_t, var_t, admin_home_t, default_context_t, winbind_var_run_t, mail_spool_t, autofs_t, device_t, device_t, devpts_t, locale_t, var_auth_t, sssd_public_t, etc_t, etc_t, proc_t, proc_t, sysfs_t, tmpfs_t, user_home_dir_t, likewise_var_lib_t, textrel_shlib_t, crack_db_t, user_tmp_t, ssh_home_t, krb5_conf_t, auth_cache_t, rpm_script_tmp_t, security_t, security_t, nx_server_var_lib_t, ssh_home_t, var_spool_t, default_t, nx_server_home_ssh_t, sosreport_tmp_t, proc_afs_t, rpm_tmp_t, dbusd_etc_t, user_home_t, var_lib_t, var_lib_t, var_run_t, var_run_t, configfile, domain, faillog_t, proc_net_t, rpm_log_t, rssh_ro_t, var_log_t, var_log_t, samba_var_t, amanda_var_lib_t, avahi_var_run_t, pam_var_run_t, net_conf_t, openct_var_run_t, sysctl_kernel_t, abrt_var_run_t, home_root_t, nscd_var_run_t, nslcd_var_run_t, pcscd_var_run_t, sssd_var_lib_t, sysctl_crypto_t, home_root_t, httpd_sys_content_t, gitosis_var_lib_t, sshd_tmpfs_t, setrans_var_run_t, admin_home_t, system_dbusd_var_lib_t, system_dbusd_var_run_t, rlogind_home_t, cgroup_t, selinux_config_t, sysctl_t, sysctl_t, abrt_t, bin_t, bin_t, cert_t, lib_t, mnt_t, root_t, sshd_t, tmp_t, var_t, var_t, var_t, default_context_t, device_t, etc_t, etc_t, sysfs_t, tmpfs_t, security_t, var_lib_t, var_run_t, var_run_t, var_run_t, net_conf_t, file_context_t, dirsrv_var_run_t, bin_t, nscd_var_run_t, pcscd_var_run_t, slapd_var_run_t, cgroup_t, selinux_config_t, cert_t, root_t. 
Then execute: 
restorecon -v '/home/kelvan'


*****  Plugin catchall (1.31 confidence) suggests  ***************************

If you believe that sshd should be allowed search access on the kelvan directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep sshd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Dominick Grift 2011-06-09 00:46:37 UTC
Migrating to Fedora from another distro or sharing your partition mounted on /home with another distro?

it you are migrating to Fedora:

yum install polictcoreutils-restorecond
relogin to you session
restorecon -R -v /home

if you are sharing your /home partition with other distros:

You need to additionally run restorecon -R -v /home each time you boot into fedora.
