Is there a good nntp client for Centos 6 that handles SSL native?
by Rock 05 May '13

05 May '13

Is there a good nntp client for Centos 6 that handles SSL native? It was difficult, to say the least, on Centos anyway, to get Pan to post to Mixmin servers, which require SSL (so we have to use Stunnel to add SSL capabilities to Pan) on Centos. Had Pan native SSL support, this wouldn't have been a problem. Hence the question: Q: Is there a good freeware NNTP client with a Centos repository that handles SSL native? Note: Here's the abbreviated sequence to install Stunnel with Pan (but it took me months to come up with this as all the tutorials on the web fail in the little Centos details). Install Stunnel: $ sudo yum install stunnel -y Read bug reports to find a stunnel init script for Centos: https://bugzilla.redhat.com/show_bug.cgi?id=455815 Add & modify that stunnel /etc/init.d/stunnel script: http://bugzilla.redhat.com/attachment.cgi?id=325164 Configure the Stunnel /etc/stunnel/stunnel.conf file: ;setuid = nobody ;setgid = nobody client = yes [nntp] accept = localhost:2119 connect = news.mixmin.net:563 NOTE: It took me months to figure out that these two now-commented lines cause stunnel to fail on my Centos box: Test Stunnel: $ telnet localhost 2119 Trying ::1... telnet: connect to address ::1: Connection refused Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 200 news.mixmin.net InterNetNews NNRP server INN 2.6.0 (20120622 prerelease) ready (posting ok) post 340 Ok, recommended message-ID <kuyt4l$e21$1(a)news.mixmin.net> From: foobar <foo(a)bar.com> Newsgroups: alt.test Subject: This is a test This is a test of stunnel to mixmin. . 240 Article received <kuyt4l$e21$1(a)news.mixmin.net> quit 205 Bye! Connection closed by foreign host. Install Pan: $ sudo yum --enablerepo rpmforge install pan -y Configure any known good Pan newsserver: [Pan]Edit->Edit News Servers->Add->(see below)->OK Address: aioe.org Port: 119 Configure a test Pan posting profile: [Pan]Edit->Edit Posting Profiles->Add-> Profile Name: New Profile Full Name: Foo Bar Email Address: foo(a)bar.com Post Articles Via: aioe.org OK Test Pan setup by reading & sending a message to alt.test. [Pan]Post->Post to Newsgroup->alt.test Now you're ready to configure Pan for SSL via Stunnel: [Pan]Edit->Edit News Servers->Add->(see below)->OK Address: localhost Port: 2119 Switch the test user to this encrypted server: [Pan]Edit->Edit Posting Profiles->Edit-> Post Articles Via: localhost OK Test this setup by reading & sending a message to alt.test. [Pan]Post->Post to Newsgroup->alt.test Note: It would have been easier had Pan native SSL capability; hence the question: Q: What nntp client handles SSL native on Centos 6?

I'm trying to install the exaile package on my newly upgraded CentOS 6.4 machine. It fails (see below) with missing dependencies on python-cddb and gnome-python2-gtkmozembed. I found this thread but there does not seem to be any resolution. \ Has anyone got this installed? Am I missing a repo?

Configuring source-specific routing
by Michael Mol 04 May '13

04 May '13

I'm attempting to configure source-specific routing so that my servers can exist on multiple subnets from multiple upstream providers. A rough diagram of the network layout: ISP1 router (blackbox, routes subnet A, address on subnet A) \ -----------eth0(firewall)eth1---((servers)) / ISP2 router (blackbox, routes subnet B, address on subnet B) The aim is to allow the servers to use both subnet A and subnet B. To allow this, any machine on both subnets must have source-specific routing configured, else packets originating from one ISP's AS will be directed at the other's router, and neither ISP cares for that. At the moment, I'm focusing on getting the second ISP properly added to the firewall box. The firewall box is using CentOS 6.4, and normally passes traffic back and forth via proxy_arp. None of my interfaces are NM_CONTROLLED, and NetworkManager is not installed, much less started. I've created a route-eth0:1 file that looks roughly like this: 10.0.0.1 dev eth0:1 \ src 10.0.0.2 \ from 10.0.0.0/29 default via 10.0.0.1 dev eth0:1 \ src 10.0.0.2 \ from 10.0.0.0/29 (Treat indented lines as continuations of the previous line) (No, the ISPs aren't giving me RFC1918 addresses; these are redacted.) If I run "ifup eth0:1", "ip route show" includes the lines: 10.0.0.1 dev eth0 scope link src 10.0.0.2 10.0.0.0/29 dev eth0 proto kernel scope link src 10.0.0.2 default via 10.0.0.1 dev eth0 Note that the "from 10.0.0.0/29" clause is missing. With the addition of a second default route on my firewall/gateway without any restriction on which traffic should go that way, my whole network, of course, tanks. I'm surprised it's been such a pain; I would have expected it to be a relatively common configuration. What's the proper way of doing source-specific routing on CentOS?

Kickstart and volume group with a dash in the name
by Dennis Jacobfeuerborn 03 May '13

03 May '13

Hi, I'm trying to setup the provisioning of new OpenStack hypervisors with cinder volumes on them. The problem is that kickstart doesn't allow dashed in volume group names? I tried this: volgroup cinder-volumes --pesize=4096 pv.02 and this: volgroup cinder--volumes --pesize=4096 pv.02 but in both cases I end up with a volume group named "cindervolumes" on the system. Any idea what I have to do to accomplish this? Defining VGs with dashes works perfectly fine on the command line. Regards, Denis

AT-2972SX
by Ray Van Dolson 02 May '13

02 May '13

Anyone know off the top of their heads if this (AT-2972SX) fiber network card will work out of the box with CentOS 6.x? Sounds like it's a Broadcom-based card, so perhaps it will, or maybe something exists for it in elrepo? Hoping to avoid needing to build custom drivers from source. Ray

trying to recover an audio CD...
by Fred Smith 02 May '13

02 May '13

I'm trying to recover data from an audio cd. it is a recording of a live session, made on a professional cd recorder, on the fly. apparently, instead of stopping it and fixating the disc, someone turned off the power. oops. I know that wodim will fixate a disk as long as it was otherwise properly terminated (I've done it more than once), but this one it won't fixate. depending on the drive I try it in, I get different messages, but in either case, it remains unfixated. so i've tried reading it with cdparanoia, but it can't do anything with it, or not that I've figured out how to do. So, can anyone suggest ways to try to recover this audio data? thanks! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ---------------------------- Do you not know? Have you not heard?
