RHDB
by Martín Marqués
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).

question on nautilus
by Paul Allen Newell
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
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
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
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
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.

Living with Systemd
by Arthur Dent
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"?

FYI, I have a CUPS server running on a RHEL 4.x machine in my office and
those queues are showing up fine in Fedora 15.
Wild guess, but is your default gateway set up properly on your F15
machine?

Just to state the obvious, whenever I've had this problem, it was almost
always because I misspelled the first entry in my list of DNS servers in
resolv.conf ;)
