55 Days of Grilling: Day 5

Tonight, we made turkey, spinach, feta burgers with fresh rolls. The rolls were my usual dough recipe (4c flour, 1T yeast, 1T sugar, 1t salt, 1T oil/butter, 1/2c wheat gluten) with a six hour rise time in a warm oven followed by a really short rise time after shaping and an egg wash. Cooked at 375 for 15 minutes — could have used an extra minute or two.

The burgers were ~1.5 lbs ground turkey, 1/4 large red onion chopped, 1 package frozen chopped spinach (defrosted with water squeezed out), 2t salt, 1t pepper, 6 oz feta, 2 eggs (minus what was used for the egg wash on my rolls), seranno chillis, and about 1/2c panko. Grilled about 5 minutes each side at a high temp. Very good — may want to try adding mustard to burger mix next time.

SCP From Solaris to RHEL?

Evidently you cannot just scp files from an old Solaris box when you’re on a RHEL/CentOS system … there’s an incompatibility between them that requires you to (1) install scp1 on the Solaris server {not likely in a prod environment} or (2) use sftp to transfer the files.

 

Server1: Red Hat Enterprise Linux Server release 7.6 (Maipo)
Server2: Solaris 5.9

lisa@server1:~/$ scp lisa@server2:/data/stuff/file1.txt ./input/
lisa@server2’s password:
scp: warning: Executing scp1.
scp: FATAL: Executing ssh1 in compatibility mode failed (Check that scp1 is in your PATH).

55 Days of Grilling: Day 4 Breakfast

Anya and I made pancakes on the grill today — I put the batter in and flip the first time, then she takes them out of the pan. She wanted to toss the cooked pancake on the grill to get some “grill marks” … which was pretty cool.

The batter is an extra vanilla-y buttermilk pancake recipe:

2c flour
1t baking powder
1t baking soda
1/2t salt

2c buttermilk
3T maple syrup
1 egg
2T oil
1T vanilla

It’s actually a powdered buttermilk, so that’s half a cup of buttermilk powder and two cups of water. I mixed up some “pancake mix” so next time we’re making pancakes … we just need to add water, oil, maple syrup, vanilla, and an egg.

Fedora — Disabling IPv6

Avatar
by Lisa

Since it’s the third time I’ve had to do this so far this year, I’m going to write down how I disable IPv6 in Fedora. Add these lines to /etc/sysctl.conf

[lisa@server~]# grep ipv6 /etc/sysctl.conf
net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6=1
net.ipv6.conf.lo.disable_ipv6=1

Then load the sysctl settings (sysctl -p) or reboot.

Without IPv6, if you do X-redirection, you may get an error indicating the redirection was refused. In journalctl, there’s an error “error: Failed to allocate internet-domain X11 display socket”. Evidently you’ve got to configure sshd to use IPv4 by setting “AddressFamily inet” in /etc/ssh/sshd_config

[lisa@server~/]# grep AddressFamily /etc/ssh/sshd_config
AddressFamily inet

 

MythTV Verbose Logging

In the process of troubleshooting UPNP/DLNA on our MythTV server, I learned that you can send logging verbosity settings while the server is running. Using the mythbackend binary with the –setverbose flag, you can specify logging level. For example:

mythbackend --setverbose http:debug,upnp:debug

What items can you set levels on? It’ll conveniently tell you — “all” or “none” override existing settings, everything else will update the current logging levels (i.e. if I’ve already got http and upnp in debug, I can use “–setverbose audio:debug” to add audio to the list of things in debug mode).

[mythuser@server /var/log/mythtv/]# mythbackend -v help
Verbose debug levels.
