OT: Documentation for Mailman
by John J. Boyer 04 Mar '12

04 Mar '12

I have Mailman installed on a VPS running Centos to handle mailing lists for my organization. However, I can't find the documentation. So far, one of our consultants has been handling it, but that costs money. At the moment the problem is that I configured a list with config_list, but the changes have not taken effect. Presumably the list must be restarted in some way, but I can't find out how. Thanks, John -- John J.

by Rob Del Vecchio 02 Mar '12

02 Mar '12

Hello all, I'm trying to install mod_python from the normal channels via RPM, though it seems that download.fedora.redhat.com is down, or moved? DNS reports it does not exist. I've seen multiple references to this domain name including on the site: http://rpm.pbone.net/index.php3/stat/4/idpl/15286937/dir/redhat_el_6/com/mo… Please help? Thank you, Rob

I then cd to that directory, and unpack a large file which is located in a user's home directory which is NFSv4 mounted. In a native directory, takes about a minute; when I cd to /mnt/foo and do it, it takes about 6.5 min. I've tried setting wsize and rsize to 1M; I've tried noatime, which someone in a post said helped, and nothing I do makes more than a second or two's difference. Clues for the poor? mark

VSftp, ssl/tls, slight issue with directory listings
by Bob Hoffman 02 Mar '12

02 Mar '12

Centos 6, stock installation, no additional repos added. vsftp works fine in regular mode, going to ssl I got issues. I get as far as 'directory listing' and it dies. It times out and disconnects. file: /etc/sysconfig/iptables-config added: IPTABLES_MODULES="ip_conntrack_ftp" (without this line, ftp normally fails, afraid it may be causing issues with the ssl) iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 21 -j ACCEPT again, normal ftp fine. vsftp file below are the additional commands I entered to get ssl/tls up and running. pam_service_name=vsftpd userlist_enable=YES tcp_wrappers=YES ssl_enable=YES implicit_ssl=yes <--- tried with and without this and the port 21 below listen_port=21 <-- see above allow_anon_ssl=NO force_local_data_ssl=NO <-- set this to yes so I can still test normal functions force_local_logins_ssl=NO ssl_tlsv1=YES ssl_sslv2=NO ssl_sslv3=NO rsa_cert_file=/etc/pki/tls/certs/vsftpd.pem ssl_ciphers=HIGH <-- this was added as I was using filezilla and it wanted different ciphers. without this it would have a tls fatal error, adding this absolved that issue. Now I have tried playing with the settings and in all cases when it can connect it dies at directory listing. Implicit ssl wants 990, but the listen_port directive can tell it to go to 21. Again, full connect, changes folders, dies at trying to display contents of initial folder. I have redone the pem a few times and even moved it in and out of the vsftpd folder just for kicks, no joy. I tried opening port 990 and that made no difference at all (even changing listen_port or leaving it commented out) so, cannot figure what is up. Most online notes are for non-centos 6 and/or generally follow this same set of commands. Most of the debug threads about this issue deal with plain connections and not tls/ssl. I can find no solution yet, has anyone out there secured their vsftp server and wanna throw me a bone? Only this and two other things prevent me from throwing out a nice video tutorial of how to go from a stock install to a fully armed and operational webserver, ssl everywhere, etc.... all nighter and no where with this one. At least not yet.

C6.2 on DELL E6520
by Bernd Bartmann 02 Mar '12

02 Mar '12

Hi, I've installed Centos 6.2 x86_64 on a DELL E6520 and nearly everything works just fine. The only problem is that the system hangs after entering "reboot". I can see that several services get stopped, but after some seconds the screen is just black and nothing happens anymore. The weird thing is that "poweroff" always works just fine. Also, I should note that I'm using the NVIDIA binary graphics driver and have disabled the "Optimus" feature in the BIOS. The problem with "reboot" happens regardless if the NIVIDA driver is installed or not. Any ideas? Best regards, Bernd

Centos6: Boot from usb 3.0
by Volker Poplawski 02 Mar '12

02 Mar '12

Hi all, I'm booting Centos6 from a usb 3.0 stick. This works fine as long as the usb-stick is connected to a usb 2.0 port. Once I plug the the usb-stick into a blue usb 3.0 port centos fails on mounting the root filesystem. Any hints on that? Regards .....Volker

IPv6 IPsec on cenots5 and centos6
by Jure Pečar 02 Mar '12

02 Mar '12

Hello, I have a couple of centos5 hosts at various offices connected with ipsec by ipsec-tools (racoon). It's a relatively straightforward configuration on ipv4, however I can't find any information how and even if it works in the same way with ipv6. What I've found is some references that it is better to use openswan on el5 and it indeed is standard on el6. It promises ipv6 support by default, however, I couldn't get it to even do phase 1 on el5 in the limited time I had available to test it. I've also found out that openswan is poorly documented not only on their site, but also in el6 manuals. So ... what are the general expiriences with ipsec on ipv6? Anyone has it running? What software did you use? -- Jure Pečar http://jure.pecar.org http://f5j.eu

pam and radius config problem
by me＠tdiehl.org 02 Mar '12

02 Mar '12

Hi, I am trying to configure ssh/pam to use freeradius as one of the authentication sources on a C6 box. I have freeradius running on a separate box with 2 factor authentication. Using the radtest utility, I can successfully authenticate. My problem is that I do not understand how to configure pam to use radius as an auth source and be sure I am not opening a security hole in my systems. While googling, I have found several howto's that talk about how to do this using the pam_radius utility but the examples do not match what is found in /etc/pam.d/sshd. What I would like to accomplish is the following: 1. Allow logins using ssh keys. 2. If that fails, Allow login via radius. 3. if not on the local network disallow login via a regular user name and passwd. I think 3 might be able to be accomplished via a match statement in sshd.conf but I am not sure. Does anyone know how to do this in a secure way? If I start modifying the pam.d configuration files, how can I be sure I am not opening up a security hole? Regards, -- Tom me(a)tdiehl.org Spamtrap address me123(a)tdiehl.org
