change sudoers remotely
by Tim Dunphy 09 Jul '13

09 Jul '13

hello list, I've been asked to give someone sudo rights across an entire environment without the benefit of something like puppet or chef or cfengine et al. What I've come up with so far is this: ssh -t miaprbicsra04v sudo -S /bin/echo "rsherman ALL=$ALL$ NOPASSWD: /sbin/service /bin/rm /usr/bin/du /bin/df" >> sudo tee /etc/sudoers Right now that's just to one host, but I plan on substituting a list of hosts once I get farther along. Problem is, the output hangs on the tee command. Not sure why. Any suggestions? Thanks, Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

CentOS 6.4 login after reboot after apcupsd shutdown - shows POWER FAILURE
by Rob Kampen 09 Jul '13

09 Jul '13

Hi list, just putting a new server through its automatic shutdown triggered by the UPS / apcupsd. All worked faultlessly, including powering up when power came back on to the UPS. So then I go to log in and get "POWER FAILURE" followed by "Authentication failure" - this is on the console via SSH I just get "POWER FAILURE" and the ssh connection drops. So I guess the, log everyone out and stop further logins instruction is still lurking around somewhere. How do I regain control of my server?? Does this mean I need to boot with a rescue disk and edit some file somewhere?? How do I prevent this re-occurring, after a perfect shutdown and restart, only to get stymied here. Google has lots of help for dealing with various corruptions due to power failure - not the case here, the POST, grub, init restart all look just fine. TIA

This isn't supposed to be difficult (how to nntp post to the Gmane Pan user group)
by Rock 09 Jul '13

09 Jul '13

I realize this is (mostly) off topic, but I'm befuddled as to *how* one can post to the Gmane Pan Users' group (gmane.comp.gnome.apps.pan.user) using any nntp USENET client (e.g., Pan, on Centos). I'm already subscribed (by having sent an email to pan-users(a)nongnu.org) but I just want that USENET group to work like *this* USENET group, where I can post using a server:port login:password combination such as we use here: Server: news.gmane.org Port: 119 Login: blank Password: blank User: Rock I've looked here (http://dir.gmane.org/gmane.comp.gnome.apps.pan.user) and if the answer is there, I don't see it (maybe I missed it?). My basic question is so simply I'm shocked I'm having to ask it (of the wrong group even) ... which is ... the following: Q: How on earth is one supposed to post to the Gmane Pan users using an nntp client (which requires a server name and port & login/password)?

spamassassin with postfix/dovecot
by Timothy Murphy 08 Jul '13

08 Jul '13

I'm trying to install spamassassin on a postfix/dovecot server, running CentOS-6.4, following the instructions at <http://wiki.centos.org/HowTos/Amavisd>. I think I have taken all the steps indicated, and the configuration seems to pass the tests suggested, although the response is much more sparse than that described: ------------------------ [tim@alfred ~]$ telnet localhost 10024 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 [127.0.0.1] ESMTP amavisd-new service ready helo localhost 250 [127.0.0.1] quit 221 2.0.0 [127.0.0.1] amavisd-new closing transmission channel Connection closed by foreign host. [tim@alfred ~]$ telnet localhost 10025 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 alfred.gayleard.eu ESMTP Postfix helo localhost 250 alfred.gayleard.eu quit 221 2.0.0 Bye Connection closed by foreign host. ------------------------ I tried sending the GTUBE spamassassin test- mail given, but I got the error message: ------------------------ Failed to transport message. The message content was not accepted. The server responded: "Message refused" ------------------------ But I see no evidence that email is being processed by spamassassin; and I don't see anything in any of the conf files setting that up. Any suggestions or elucidation gratefully received. -- 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

Having difficulty exporting display
by Yves S. Garret 08 Jul '13

08 Jul '13

Hello, This is my issue, my remote machine (CentOS 6.3, hosted in Azure windows environment) has an application that I need to test on my local box (CentOS 6.4, a laptop behind a router). Now, this is what I'm doing and the issue that I'm encountering: Local: $ xhost + $ ssh -X someusername(a)somehostname.net -p 49283 Remote: $ export DISPLAY=192.168.1.6:0.0 $ xclock ... and nothing, it just sits there and no xclock shows up :( . I'm fairly convinced that this is due to my router, but I don't know how to deal with it. Any ideas? Am I way off in my guess?

fstab, unusual behavior of "missing UUID"
by Joseph Hesse 06 Jul '13

06 Jul '13

I have the following as the last line of my /etc/fstab file on a computer running CentOS6.4.. UUID=3b550884-8d05-41a5-a205-17b6d7269dd1 /mnt ext3 rw,suid,dev,exec,noauto,nouser,async 0 2 The UUID refers to an ext3 partition of a removable USB drive. If the USB drive is not plugged into the computer the computer will not boot. It seems that this is the incorrect behavior since "noauto" means there is nothing to mount. I noticed this situation since an almost identical /etc/fstab on a Fedora 18 computer will boot without the USB drive being plugged in. The reason this is important to me is that I want to plug my USB drive into a running computer and then mount it with "# mount /mnt" so I can do backups. Thank you, Joe Hesse
