rsh busted?
by Tom Horsley
1. The first person to lecture me about rsh and security
gets shot :-).
2. On fedora 24, I can't get some test scripts to run
which have used rsh since time first fell upon the
face of the earth (and they are behind a firewall on
a local network anyway).
I've installed rsh and rsh-server on all the boxes,
I've enabled rsh.socket. If I run rsh to localhost,
it works fine. The test user has a ~/.rhosts file
with all the names of all the systems mentioned as
valid.
But when I get on another system and try to rsh in,
it always tells me "no route to host". Anyone have
a clue what else to check?

NetworkManager: openconnect VPN connections won't work in F24
by Joachim Backes
Hi all F24 users,
I established a new opneconnect-VPN connection by the GNOME
NetworkManager menue, but this connection does not work. I'm endlessly
requested for a valid Userid/Password.
But if establishing this openconnect VPN connection by the cli
/sbin/openconnect, the connection works immediately.
Anybody seas this too?
Kind regards

looking for a BASH tool
by SternData
Years ago, I used a tool called CED and PCED on DOS systems. I could
type in "abc" and press an up-arrow and it would walk back through my
stack of DOS commands showing only those with "abc" in them.
There's *got* to be a similar tool for bash, but my google-fu is weak today.
Thanks for suggestions or links.

rpmfusion for F24
by Clifford Snow
I use the non free rpmfusion for Nvidia drivers. (The nouveau doesn't work
for my card, no or insufficient thermal controls.) Where is the best place
to ask for drivers compiled for the latest kernel, 4.5.7-300?
Thanks,
Clifford

Default IP address for multihomed hosts changed in F24
by Sam Varshavchik
Not sure if this is known changed behavior in F24, but:
For the longest time I had /etc/sysconfig/network-scripts/eno2 specify:
TYPE=Ethernet
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
NAME=wan0
UUID=71e6ac4b-c693-4c20-aa0d-e1a63b7373fe
ONBOOT=yes
IPADDR1=216.254.115.102
PREFIX1=24
IPADDR2=216.27.136.223
PREFIX2=24
HWADDR=0C:C4:7A:32:C1:83
IPADDR=216.254.115.190
GATEWAY=216.254.115.1
PREFIX=24
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
This host has three IP addresses, and up until now the default IP address
for outgoing IP traffic was always 216.254.115.190, specified by IPADDR.
It appears that, right now, all of my outbound traffic now appears to come
from one of the other IP addresses, 216.254.115.102.
This is true even if the outgoing socket explicitly binds to 216.254.115.190:
Sending mail to gmail, with an explicit bind(), strace shows:
13232 bind(5, {sa_family=AF_INET6, sin6_port=htons(0), inet_pton(AF_INET6,
"::ffff:216.254.115.190", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0},
28) = 0
13232 fcntl(5, F_SETFL, O_RDONLY|O_NONBLOCK) = 0
13232 getsockopt(5, SOL_SOCKET, SO_TYPE, [1], [4]) = 0
13232 connect(5, {sa_family=AF_INET6, sin6_port=htons(25),
inet_pton(AF_INET6, "::ffff:173.194.206.26", &sin6_addr), sin6_flowinfo=0,
sin6_scope_id=0}, 28) = -1 EINPROGRESS (Operation now in progress)
13232 select(6, NULL, [5], NULL, {60, 0}) = 1 (out [5], left {59, 975901})
13232 getsockopt(5, SOL_SOCKET, SO_ERROR, [0], [4]) = 0
13232 getsockname(5, {sa_family=AF_INET6, sin6_port=htons(41394),
inet_pton(AF_INET6, "::ffff:216.254.115.190", &sin6_addr), sin6_flowinfo=0,
sin6_scope_id=0}, [28]) = 0
13232 select(6, [5], [], NULL, {300, 0}) = 1 (in [5], left {299, 975360})
13232 read(5, "220 mx.google.com ESMTP 92si8123707qkx.29 - gsmtp\r\n", 512)
= 51
Gmail still shows 216.254.115.102 as the received-from IP address. I note
that getsockname() insists that the socket is 216.254.115.190
This host is using masquerading, with firewalld. I suspect that this is
firewalld's doing.
ip addr's output:
2: eno2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group
default qlen 1000
link/ether 0c:c4:7a:32:c1:83 brd ff:ff:ff:ff:ff:ff
inet 216.27.136.223/24 brd 216.27.136.255 scope global eno2
valid_lft forever preferred_lft forever
inet 216.254.115.102/24 brd 216.254.115.255 scope global eno2
valid_lft forever preferred_lft forever
inet 216.254.115.190/24 brd 216.254.115.255 scope global secondary eno2
valid_lft forever preferred_lft forever
inet6 fe80::ec4:7aff:fe32:c183/64 scope link
valid_lft forever preferred_lft forever
Anyone knows what could be the reason for this, I'd like to have
216.254.115.190 as the default externally-visible IP address.

Re: Brasero: can't choose a directory. [SOLVED]

This works. Thank-you, Fred.

This does not work. That '+' does not pop up a browser or do anything
else until after a directory/file has been selected.

This works. Thank-you, Rick.

rpmbuild error (wbar) on F24
by Ranjan Maitra
Hi,
I have a local rpm that I have created using wbar. The spec file is here:
https://paste.fedoraproject.org/384973/14669508
I have successfully created this rpm up to Fedora 23. But have been unable to do so this time around in F24.
I get the following errors:
....
cc1plus: all warnings being treated as errors
Makefile:551: recipe for target 'wbar-Main.o' failed
make[2]: *** [wbar-Main.o] Error 1
make[2]: *** Waiting for unfinished jobs....
make[2]: Leaving directory '/home/maitra/rpmbuild/BUILD/wbar-2.3.4/src'
Makefile:404: recipe for target 'all-recursive' failed
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory '/home/maitra/rpmbuild/BUILD/wbar-2.3.4'
Makefile:345: recipe for target 'all' failed
make: *** [all] Error 2
error: Bad exit status from /var/tmp/rpm-tmp.qtyTEY (%build)
I was wondering what is going wrong here. I am not very familiar with spec files, but have successfully built rpms by looking at other spec files. Btw, here is the source code for wbar:
https://code.google.com/archive/p/wbar/downloads
This not being my own software, I would be willing to submit this to fedora (when it works and if I can get sponsors) but for that, my rpm needs to get created.
Thanks again!
Best wishes,
Ranjan

Brasero: can't choose a directory.
by William Mattison
I'm using Fedora-23, last patched last Thursday, 6/23.
Last Friday, I was trying to back up some directory trees to DVD. I
launched Brasero, and chose "New Data Project". The result should have
been a list of the directories and files at the home or root level. The
file list area was blank. When I try "Project" -> "Open", a populated
file browser shows up. I can navigate the file system successfully, but
I can't find a way to select a directory for copying to the DVD.
This all worked in March in F-22, when I backed up before upgrading to
F-23. What am I doing wrong? Or what have I not done that I need to do?
Thank-you in advance for your help.
Bill.

3.6.x version necessary before upgrading to 4.0
by Gianluca Cecchi
Hello,
is there any requirement to update at latest 3.6.x version the engine
before upgrading to 4.0? Or could I have for example 3.6.3 and directly
upgrade to 4.0?
Do you test upgrade only from latest previous version or what?
And what about nodes in case they start as plain CentOS 7.x in 3.6.x?
Thanks,
Gianluca
