logwatch/shorewall warnings
by Timothy Murphy 05 Feb '10

05 Feb '10

I'm running a little web-server under CentOS-5.4 , with shorewall as firewall. I used to get messages about attempted intrusions, with the IP addresses of those attempting to connect. This stopped some time ago, and my logwatch reports now are very bare. I don't recall changing the settings of logwatch or shorewall. Has there been some default change? I should say that I'm not sure if I mind losing these warnings, as I never used to do anything about them. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

I had added user umarzuki to wheel group # usermod -G wheel umarzuki *Yes, I can use/setup sudo but I do this just for learning purpose My /etc/pam.d/su as below auth sufficient pam_rootok.so # Uncomment the following line to implicitly trust users in the "wheel" group. #auth sufficient pam_wheel.so trust use_uid # Uncomment the following line to require a user to be in the "wheel" group. auth required pam_wheel.so use_uid auth include system-auth account sufficient pam_succeed_if.so uid = 0 use_uid quiet account include system-auth password include system-auth session include system-auth session optional pam_xauth.so when i su to user umarzuki and view its id output $ id uid=500(umarzuki) gid=500(umarzuki) groups=10(wheel),500(umarzuki) and i tried run $ yum update Loaded plugins: fastestmirror You need to be root to perform this command. but i managed to change the interface's IP with this command $ /sbin/ifconfig eth0 192.168.1.1 netmask 255.255.255.0 up Is there a step that i missed? -- Regards, Umarzuki Mochlis http://debmal.my

OpenSSH-5.3p1 selinux problem on CentOS-5.4.
by James B. Byrne 04 Feb '10

04 Feb '10

Note: I am digest subscriber so if you could copy me directly on any reply to the list I would appreciate it very much. I sent this to the OpenSSH list (secureshell(a)securityfocus.com) yesterday and received no response so I am asking here in hopes that someone else has run across this problem on CentOS. We have encountered a situation that requires sftp access to one of our server by an outside agency. This will be used for a data push application only and we need to secure our server from trespass via this access. After a modest amount of research we decided that the best answer was to use a more recent version of OpenSSH (5.3p1)that supports chroot as a configurable option. I obtained the software from the openssh.org website and built it using the libedit packages from the CentOS testing repo. These were the option used: ./configure --prefix=/opt --with-libedit --with-md5-passwords --with-pam --with-selinux --with-tcp-wrappers The new server software works fine for regular ssh/sftp users. However, when logging on as a member of the chroot group we obtain this error: ssh_selinux_getctxbyname: ssh_selinux_getctxbyname: security_getenforce() failed I have found reports of this exact error via Google in several places dating back to 2006, but these all seem to devolve into either: this has been fixed in version x.y.z on distribution Q, where x.y.z is less than 5.3 and Q is not CentOS. Or, the selinux filesystem has to be mounted inside the chroot directory. Since I assume the former is never going to happen for CentOS, at least not in time to do me any good, I am looking for an explanation of what the latter means and how it is accomplished. Our current SELinux status on that host is: # sestatus SELinux status: enabled SELinuxfs mount: /selinux Current mode: permissive Mode from config file: permissive Policy version: 21 Policy from config file: targeted Our chroot directory path is: /var/data/sshchroot The questions are: 1. Is it possible to mount the selinux filesystem twice on the same host having different roots? 2. If so, then how is this accomplished? 3. If not, then is there anything else that I can do, besides disabling selinux support in the sshd daemon, to get this to work? Sincerely, -- *** E-Mail is NOT a SECURE channel *** James B.
