RHDB
by Martín Marqués 05 Aug '11

05 Aug '11

What's the availability of RHDB? I used to use Visual Explain and Administrator, which were quite cool at the moment (can't recall, but maybe 3 or 4 years ago). -- Martín Marqués select 'martin.marques' || '@' || 'gmail.com' DBA, Programador, Administrador

question on nautilus
by Paul Allen Newell 05 Aug '11

05 Aug '11

I am trying to change the default text editor in what I think is Nautilus from gedit to vim. All the info I see online either addresses it for another Linux flavor and/or seems to imply that I should see Gvim as an option when I go into file->preferences (which I do not). I spotted one link with seemed to imply that it might be something to the effect of "/usr/bin/vim @1", but not enough for me to trust. I tried searching in ~.local and ~.gnome* and ~.nautilus for any reference to gedit thinking I could change a file, but found nothing. Suggestions? (and that includes a scolding for "why didn't you look in the obvious place?" which is not obvious to me) Thanks, Paul

No Gnome 3 for me
by John Wendel 05 Aug '11

05 Aug '11

Anybody have a solution for the bug (?) that keeps Gnome 3 from working with Nvidia 7300 video cards? Specifically, the keyboard and mouse clicks don't work (but ctrl-alt-backspace does). It's been a while, I thought this would surely get fixed. I'm running F15 with the latest updates and the latest Nvidia driver. Thanks, John

question regarding gcc on f14
by Paul Allen Newell 05 Aug '11

05 Aug '11

While dealing with some compiling issues, I noticed that the current gcc on F14 is 4.5.1 and that gcc.gnu.org says that the latest is 4.5.3 ... and it appears they've gone off into 4.6.x. I would like to know if Fedora plans to migrate F14 to 4.5.3 or stay at 4.5.1. I don't have any issue with 4.5.1, just trying to get information about where F14 will end up Thanks, Paul

mail / mailx question
by Paul Allen Newell 04 Aug '11

04 Aug '11

I am running an F14 system which is pretty much out-of-the-box except I have the machine hardcoded to 192.168.2.13 to keep my network happy. I see all sorts of uses of 'mail [...] root@localhost' which work great when I look in /var/spool/mail/root. I have read the mail / mailx documentation and tried sending mail to both root and my local account and it works great. The man pages keep using examples like "joe(a)somewhere.com", but when I try that with my email account (name(a)whatever.edu), it fails (as in nothing happens and I sometimes get resend errors). I can ping whatever.edu successfully. I am certain this is a stupid pilot error, but can't figure it out. Any suggestions? Thanks in advance, Paul

dns resolver issue
by Genes MailLists 04 Aug '11

04 Aug '11

I have a C program which does dns lookups of a large number of IP addresses by using calls to getnameinfo() in a loop. Its designed to be a very fast way to do lookups on cidr blocks. On all earlier versions of fedora (f8-f14) this works just fine. On F15 it does not always work - sometimes it returns nothing. Run it again - nothing - run it a 3rd time and it works fine - printing out the list of ip/hostname pairs. Sometimes it works fine first time. The /etc/resolv.conf has the localhost bind (127.0.0.1) as the first entry. It was recompiled on f15 ... since its intermittent its annoying to debug - has anyone else seen this kind of problem ? Thanks. gene

Living with Systemd
by Arthur Dent 04 Aug '11

04 Aug '11

Hello All, I am gradually getting used to systemd. I can now just about force my fingers to type "systemctl restart httpd.service" even though my brain is itching to write "service httpd restart" and I find this cheatsheet to be very useful: http://fedoraproject.org/wiki/SysVinit_to_Systemd_Cheatsheet However, there is one thing I find *incredibly* frustrating and that is the paucity of information when things go wrong. When I am tinkering with some app or other and I mess something up (as I often do), being told that the app has "entered a failed state", but not *WHY* it failed is very unhelpful. At least with SystemV you would be told that it's because a file is missing, permission problem, config error... etc. Looking into /var/log/messages is no help (it just repeats the same message) and very often the program's own logs are of no use because the app has not started logging. I have looked at man systemctl but can see no "verbose" (or similar) switch. I find that the only way I can troubleshoot a failing process is to start the program directly from its executable, or by manually running the init.d script. Then I get some useful information as to why the program failed, and fix it. Jul 22 00:01:11 mydomain systemd[1]: httpd.service: control process exited, code=exited status=1 Jul 22 00:01:11 mydomain systemd[1]: Unit httpd.service entered failed state. The above error was caused by one rule in the thousands of mod-security rules that I had just updated. Starting httpd directly from the init script I found this: Syntax error on line 91 of /etc/httpd/modsecurity.d/base_rules/modsecurity_crs_20_protocol_violations.conf: Error creating rule: Unknown variable: REQBODY_ERROR and I could see exactly what I needed to fix. Am I missing something? Is there a way to get helpful error messages with systemd that I don't know about - or are we stuck with "code=exited status=1"? Mark

Wild guess, but is your default gateway set up properly on your F15 machine?

After updating to Fedora 15, syslog-ng no longer has an init script. How do you restart it?
