Fedora 11 FTP
by Bernie VK2KAD 23 Jul '09

23 Jul '09

In response to Harold's question - there is a SFTP service running on the Fedora11 image. At least in the Hercules image that is. Using it I was able to FTP the Midnight Commander RPM to Fedora after downloading it on my Windows host. I used psftp as the Windows Client (From the makers of Putty). Unfortunately the RPM wasn't installable as there were many unmet dependencies. I am now in the process of setting up Hercules on Ubuntu - hopefully my Windows networking woes will go away and I will be able to 'yum install' everything I need, then I can just ship the image back to windows !! (Well that's my plan for now) Bern -----Original Message----- From: fedora-s390x-bounces(a)lists.fedoraproject.org [mailto:fedora-s390x-bounces@lists.fedoraproject.org] On Behalf Of fedora-s390x-request(a)lists.fedoraproject.org Sent: Wednesday, 22 July 2009 10:00 PM To: fedora-s390x(a)lists.fedoraproject.org Subject: fedora-s390x Digest, Vol 8, Issue 7 Send fedora-s390x mailing list submissions to fedora-s390x(a)lists.fedoraproject.org To subscribe or unsubscribe via the World Wide Web, visit https://admin.fedoraproject.org/mailman/listinfo/fedora-s390x or, via email, send a message with subject or body 'help' to fedora-s390x-request(a)lists.fedoraproject.org You can reach the person managing the list at fedora-s390x-owner(a)lists.fedoraproject.org When replying, please edit your Subject line so it is more specific than "Re: Contents of fedora-s390x digest..."

What I was asking is if a FTP server was already installed on the Fedora 11 image or not that would allow Fedora 11 to be a FTP server as opposed to an FTP client. I am assuming it has a client installed. Maybe not. Anyway, this list would easily answer such questions.

Apparently (but I could be wrong), AO_t is pretty much guaranteed to be a host architecture 'int'. On s390x, an int is a 32 bit entity. On s390x, the s390.h code performs a "CSG" - which acts upon 64 bit registers, and the target memory address will be seen as a container for a 64 bit value (basically storing a 64 bit value in a 32 bit container - thus overshooting by 4 bytes). The Compare and Swap instructions are as follow : s390/32 bit : CS s390x/32 bit : CS s390/64 bit : CDS s390x/64 bit : CSG or CDS s390/128 bit : N/A s390/128 bit : CDSG See z/Architecture Principles of Operation - SA22-7832-07 (aka dz9zr007.pdf) Page 7-66 --Ivan

Thought I would forward this request to this list. I am with this poster. It would be great to have something better than vi. I just completed installing the latest released disk and am about to add a new disk for /home. Is there an FTP server installed? Better yet, is there a place that has a list of the installed packages?

Booting the installation images
by Karsten Hopp 10 Jul '09

10 Jul '09

Hello, It took me a while, but I've finally figured out the pungi problems where almost no libraries got copied into the installation initrd. I'll prepare a patch and will send it to David So far I run into several problems with those images: - all parameters given in the parm file are ignored and I had to enter the whole network configuration again - insmod doesn't load any modules, which means that the linuxrc can't load required modules. I currently have to drop to a shell and load them manually with modprobe - dbus-daemon doesn't start automatically, but the loader relies on it - the loader doesn't get started automatically and hangs at the first screen when started manually. - wpa_supplicant gets started ?!

RE: fedora-s390x Digest, Vol 7, Issue 3

Hi all Can anyone tell me how to add more DASD to the Hercules version of Fedora11?? I was wanting to use Fedora11 as a rescue system for one of my other zLinux's - my plan was to add the DASD image to the Hercules config file - after IPL I should be able to mount the broken disk and fix it... After doing this the new devices wasn't detected ?? A quick Google said that 'kuzdu' didn't recognise HDDs - not sure what that all means but my suspicion is that the Fedora11 is pretty new and bare bones. Thanks in advance for any suggestions. Bern

current state of the services network and NetworkManager
by Steffen Maier 02 Jul '09

02 Jul '09

Hi all, while I was trying to get all different kinds of network device types of s390x working (bug reports in bugzilla pending), I got it working nicely with the traditional network service, which is what users would typically use in a data center. NetworkManager requires the activation (chkconfig) of the services messagebus, haldaemon. Then NM works with static IP settings through nm-system-settings, which is what we need in linuxrc.s390/loader/anaconda, and seems to detect at least qeth and lcs devices (it doesn't touch ctc and netiucv). Tested with NetworkManager-0.7.1-4.git20090414.fc11.1.s390x. Support for the s390 bus types ccw, ccwgroup, and iucv (which is sufficient for all network types as well as dasd, zfcp, and tape) has been in HAL since 2005 [http://lists.freedesktop.org/archives/hal/2005-June/002628.html, http://cgit.freedesktop.org/hal/commit/?id=2ed3c042c13f741b8a2166e4551d9dbe…]. Only when NM changes to udev for device sensing there might need to be new support for s390. See the attachment for an example output of lshal of a z/VM 5.3 guest on a z10 with 12 different types of network devices as well as dasd and zfcp. If lo and eth0 (a real OSA NIC) are the only network devices defined by means of ifcfg file in /etc/sysconfig/network-scripts/ and they have been brought up by the network service on boot, I can startup NM and eth0 keeps working.
