Hi, Using hercules, I managed to get Fedora Core Development for s390 installed and running. My remaining issue is that the ctc0 network interface doesn't come up in the installed system, although it got configured fine and got used at install time. The network service reports "OK", but the interface doesn't appear. Here's the content of my ifcfg-ctc0 file, it's the post-install default and seems correct to me : # IBM CTC DEVICE=ctc0 BOOTPROTO=static BROADCAST=192.168.200.3 IPADDR=192.168.200.3 MTU=1500 NETMASK=255.255.255.255 NETWORK=192.168.200.3 ONBOOT=yes QETH=yes REMIP=192.168.200.4 SUBCHANNELS=0.0.0600,0.0.0601 TYPE=QETH And the last lines of the dmesg output (nothing regarding ctc0...) : [...] ip_tables: (C) 2000-2002 Netfilter core team NET: Registered protocol family 10 Disabled Privacy Extensions on device 002155f4(lo) IPv6 over IPv4 tunneling driver divert: not allocating divert_blk for non-ethernet device sit0 Is this a known problem? I could investigate some more, but it's just so annoying to have to prefix all commands with dots and not having command completion... if only I got the network working! ;-) The last thing I tried was modprobing the ctc module (I checked, it has no options itself, dunno where the SUBCHANNELS stuff is needed) and doing a "service network restart", but no better even though it reports "OK" for ctc0, and ifconfig on ctc0 still reports that the device isn't found.
