Check the permission all your top level directories and the .ssh directories and it's files. Basically, group and other writes are forbidden since it would allow other people to change your keys. If you're allowing the use of passwords and keys, then it's just falling back to passwords because the permissions are incorrect. And I presuming the secret key is not encrypted, i.e., you never set a passphrase - hence the root login works without a password since the permissions are correct for key exchange. Also, on Redhat/Centos/Solaris machines, it's PermitRootLogin no or PermitRootLogin yes and not PermitRootLogin without-password There should be separate entry for passwords PermitEmptyPasswords no You have to be barking mad to allow root connections - or any connection - with an empty passwords. Note, this isn't Mac mailing list so your mileage will vary. Without a sshd_config file it's hard to help you. -- Enjoy global warming while it lasts.

Trying to rebuild srpm from fedora....
by Tom Bishop 02 Feb '10

02 Feb '10

So I am trying to rebuild this source rpm from fedora 10, shutter-0.85.1-1.fc10.src.rpm -its a screen capture application ( http://shutter-project.org/ ) that I have been unable to find in any repos, although it is in the fedora repos. Thought I would give it a go and try to rebuild the rpm, so here is the error that I am getting: + desktop-file-install --delete-original --dir /var/tmp/shutter-0.85.1-1-root-itsupport//usr/share/applications /var/tmp/shutter-0.85.1-1-root-itsupport//usr/share/applications/shutter.desktop Must specify the vendor namespace for these files with --vendor error: Bad exit status from /var/tmp/rpm-tmp.38313 (%install) Anyone have any tips or 2x4 :) to point me in the right direction I would appreciate it, thanks. Oh yeah, running centos 5.4 i386 arch, thanks again.

Ah, not really, rpmbuild is complainig about: /usr/share/applications/centos5-shutter.desktop It's possible the spec file originally mv'd the file to remove the fedoraX, but since the distro changed the file name changed. You'll need to edit the spec fix. -Ross

This is something I've not run across before. Using "su -" did the trick. CentOS Wiki is (almost) always your good friend :-) http://wiki.centos.org/TipsAndTricks/BecomingRoot Akemi

Browser related question
by Rajagopal Swaminathan 01 Feb '10

01 Feb '10

Greetings, How does one monitor if a site is being accessed using browser? IOW, I just want to know if a user has launched a session thru Firefox. I basically want to know if a user has tried to access the webserver and unable to reach it and log such instances. I am using cron and curl to seperately monitor the link. Any clues? Centos 5.2/Gnome/Firefox 3.0.16 Regards Rajagopal

DynDNs.org compatible server scripts
by Rajagopal Swaminathan 01 Feb '10

01 Feb '10

Greetings, I know this mail is slightly OT. But my DNS server and and all other compute nodes (currently around 80) run Centos. Has anybody come across some package script which can be used to listen to request from DynDNS.org clients which can be found commonly in the devices? I have a scenario wherein many devices having Dynamic IP scattered across a geographical region. most have an embedded Dyndns.com client which can be enabled. I configure a Private Dynamic DNS server at a central location. Now I need something which will listen to the request thrown out by the devices and update Dynamic DNS Server. TIA Regards, Rajagopal

APC Smart-ups "status codes" (slightly OT)
by m.roth＠5-cent.us 01 Feb '10

01 Feb '10

We got replacement battery "kits" for some of our APC UPS' (Smart-UPS, rackmount). I put them into one tray (it's for an RBC 43, which takes 8, and weighs a ton), and put it in, and let it charge. Idiot "change battery" led stays on. So I hit the test button, it discharges very rapidly (a good number of servers on this), and the led stays on. For some reason, apcupsd's USB test fails, with an HIDDEV i/o error. So I got rid of the weird APC usb cable, and put in one of their serial cables, and run the "smart" test (the USB does more), and get results showing everything's fine. But the idiot light's still on. So, looking at all the values that the "apcsmart" choice can give me, the first thing is UPS status. I've been googling for a while, and can't find a single reference to it. Anyone have a link to somewhere that will give me the status codes (and their meaning)? Thanks in advance. mark

CentOS 5.4 64-bit: Java web browser plugin for 64-bit FireFox?
by Robert Heller 01 Feb '10

01 Feb '10

Does there exist *anywhere* a Java web browser plugin for 64-bit FireFox? The SUN 1.6<mumble> JDK (jdk-6u18-linux-amd64.rpm) does NOT include the Java web browser plugin library. java-1.6.0-openjdk-1.6.0.0-1.2.b09.el5.x86_64.rpm does not have one either. Should I install the *32-bit* SUN 1.6<mumble> JDK and use the 32-64 bit wrapper? I've searched the web and read the wiki (which only shows installing the 32-bit Java web browser plugin). -- Robert Heller -- 978-544-6933 Deepwoods Software -- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows heller(a)deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/
