Serial port operation -
by Bob Goodwin
I have two F-15 computers with a program that should be toggling
RTS and DTR on the serial port. One works as expected this one I
am on now does not.
I haven't had much to do with the serial port and don't know how
to troubleshoot it.
Can someone offer a suggestion where to begin?

That much I know, as I googled I already also know that device drivers can be found. But my question was if it was useable or if it'll feel cumbersome. I wish to hear (read) from someone who actually tried this.

Fact check: why are icedtea binaries named openjdk?
by Fernando Lozano
Hi there,
I heard that iced tea binaries have to use the openjdk name on binaries
(such as the Fedora packages) because of some agreement with Sun. Sun was
to provide help running the TCK and integrading iced tea patches into
openjdk, in return icedtea downstream would use the openjdk name. Is this
correct? I could not find a reference on the subject.
Or maybe it was a clause on the "special tck license grant" for open source
projects based on openjdk.
I guess there are people on the list who can tell what happened. :-)

mkfs.ext4: No such device or address while trying to determine filesystem size
by Jackson Byers
trying to format a partition as ext4
getting following error
[root@f14 ~]# mkfs.ext4 /dev/sdc7
mke2fs 1.41.12 (17-May-2010)
mkfs.ext4: No such device or address while trying to determine filesystem size
[root@f14 ~]#
I did this same command earlier today and it worked.
Since then, I made some kind of error copying to that partition,
after it was mounted to /mnt/sdc7.
So I was trying to reformat.
Also, now if I try to mount it I can't even see what is in it:
[root@f14 ~]# mount /dev/sdc7 /mnt/sdc7
mount: /dev/sdc7 is not a valid block device
This must be newbie stuff, but I am lost.
mount shows sdc9 for example
/dev/sdc9 on /grubp type ext3 (rw)
but fdisk -l shows only sda, sdb,
nothing for sdc
df -kh does show sdc9, nothing for sdc7
root@f14 ~]# df -kh

Sorta kidding -- see the ;-) ?
But isn't Red Hat kindgly giving time of some employees to work on IcedTea, and didn't they do the same for GCJ ?

Very reassuring. So it's only the work involved in checking each one of thousands specs.
I remember being bitten by this issue on OpenJDK 6 x Java 5. I even submitted a patch to Fedora Xerces package, so I could run Fedora provided ant with proprietary Sun JDK 5. Nice being able to say I had a small contribution for the wonderful distro which is Fedora. :-)

Thanks for the info.
So all F16 packages build with OpenJDK 6 are supposed to work with the also supplied GCJ ? Or didn't you tested so far ?

Problem serving DHCP to Virtual Guests
by Patrick Lists
Hi,
I have a workstation with Fedora 16 using NetworkManager getting a
static IP address via DHCP from a central DHCP server. I have a couple
of VMs on that workstation that use a routed network device in libvirt
that I would also like to acquire their IP address from the central DHCP
server.
I set up the virtual routed network device virbr1 and configured a VM
(with CentOS 6) to use it. When the VM starts I see in Wireshark the
DHCP broadcasts on the virbr1 interface but those broadcasts are not
seen on the p21p1 (the old eth0) interface on the workstation and
definitely don't make it to the central DHCP server. I guess I may need
some additional IPTables rules to forward the VMs DHCP requests to the
central DHCP server? Does anyone know what IPTables rule(s) I should add
to make this work?
Here is an overview of configs. Apologies for the iptables linewrap. I
don't know how to force Thunderbird not to do that but I also put the
info up at pastebin: http://pastebin.com/3u6cVUux

But someone told about incompatibilities on Fedora Java packages that prevented OpenJDK 7 / IcedTea 2 from being the default Java in F16. So I can expect OpenJDK 7 to be the default Java when F17 is released?

This meant the community and/or Red Hat did not get the JSR-336 TCK yet. It doesn't mean there is any problem with license or process that prevents Fedora to get the TCK and certifiy OpenJDK 7 finaries for F16 or a future release.
Am I correct? If I am, is there a timeframe for certified builds? I'd hate having to get Oracle proprietaty binaries just to satisfy bureucratic requirements. :-(
And while we're talking about Java 7, I heard about serious problems preventing some open source packages like Lucene from running under Java 7 on production settings. Anyone on the list can vouch for Java 7 in full production, or can based on experience advise against that? I rememeber all first releases (.1, .3) of JDK were somewat problematic (bugs).
