I configured wireguard to use the dns server on the the same computer. Clients could not use it. This needed a change to /etc/bind/named.conf.option. I needed to add the network that used by wireguard to "trusted" ie 10.157.73.0/24<br /><br />acl "trusted" {<br /> 90.155.48.128/27;<br /> 81.187.211.32/28;<br /> 2001:8b0:7c:1::/64;<br /> localhost;<br /> 10.157.73.0/24;<br /> };<br /> </p><p>Because of this in the configuration.<br /><br />allow-recursion {<br />trusted;<br />};<br /><br />2. I run fail2ban. I added the wireguard network to /etc/fail2ban/jail.d/mychanges.conf<br /><br />[DEFAULT]<br />ignoreip = 127.0.0.1/8 ::1 10.157.73.0/24<br /> </p><p>3. At this point, ipv6 was working from my macbook. I could see this as I run a bash script that pings various places. It was obvious that my macbook could not ping outside my local network using ipv4.<br /><br /><br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiKKS8yE_6VzvhhEFJ0grHsjZiCohyr-bMszuBJBdOHPJ1VnRuG8K0TpMQDW--riRXJE23ocPO1g-CZnTtLlhSdxZQ4u13YueO5p6PmieRDO1UxyiuBFsGVcB2U09mVlLrKU_xA-155byU7JGEUAPhCz57QEdXNBJP-spqbA68IeQBpRmx0cQ/s1572/badpings.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="786" data-original-width="1572" height="344" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiKKS8yE_6VzvhhEFJ0grHsjZiCohyr-bMszuBJBdOHPJ1VnRuG8K0TpMQDW--riRXJE23ocPO1g-CZnTtLlhSdxZQ4u13YueO5p6PmieRDO1UxyiuBFsGVcB2U09mVlLrKU_xA-155byU7JGEUAPhCz57QEdXNBJP-spqbA68IeQBpRmx0cQ/w368-h344/badpings.jpg" width="368" /></a><br /> </p><p> </p><p>This was getting beyond my level of competence but I ferreted around and Googled and discovered a bad line in nftables:<br /><br />chain POSTROUTING {<br /> type nat hook postrouting priority srcnat; policy accept;<br /> oifname "eth0" ip saddr 10.185.2.0/24 counter packets 0 bytes 0 masquerade comment "wireguard-nat-rule"<br /> }<br /><br />10.185.2.0/24 is incorrect.<br /><br />Then I discovered<br /><br />pivpn debug<br /><br />And that found the error and put in the correct line.<br /><br /> chain POSTROUTING {<br /> type nat hook postrouting priority srcnat; policy accept;<br /> oifname "eth0" ip saddr 10.157.73.0/24 counter packets 0 bytes 0 masquerade comment "wireguard-nat-rule"<br /> oifname "eth0" ip saddr 10.185.2.0/24 counter packets 0 bytes 0 masquerade comment "wireguard-nat-rule"<br /> }<br /><br /><br /><br />Clients<br /><br />I did not have any problems with clients.

Something to be looked at. And the ipv6 address on the server is "fd11:5ee:bad:c0de::2/64" which looks a bit ominous. And my website, http://clifford.ac, hosted on another Pi, shows ipv4 in the top corner when viewed through the vpn tunnel.<br /><br /><br /> </p><br />Alan Cliffordhttp://www.blogger.com/profile/07203284236816302240noreply@blogger.com1tag:blogger.com,1999:blog-13578802.post-42198721350484098272022-04-08T16:15:00.001+01:002022-04-08T16:15:06.159+01:00Škoda Octavia key fob battery<p> The car told me to replace the battery in the keyfob.

I go to https://niblick.uk in a browser and it wasn't using default-ssl.conf. By enabling and disabling virtual hosts it seems that it was using clifford-ssl.conf although there is no trace of niblick.uk in that file.<br />
<br />
I copied default-ssl.conf to 000-default-ssl.conf, enabled that and disabled the original on the dubious analysis that 'c' comes before 'd' and the non-ssl conf file starts with 000.<br />

This appears to have been successful.<br />

After reboot, radicale and isc-dhcp-server don't start. Or, rather, radicale starts and then exits.<br />
<br />
apache2 and sshd ports have been configured so that ssh over port 80 to a separate ip number is possible <br />
<br />
sshd starts but not all ports are assigned<br />

<br />
<span style="font-size: small;">apache 2 fails to start</span><br />
<br />
The radicale, isc-dhcp-server and apache2 problems are detectable using "systemctl show" as the failure is detectable<br /><br />
<span style="color: #b45f06;">LoadState=loaded</span><br />
<span style="color: #b45f06;">ActiveState=active</span><br />
<span style="color: #b45f06;">SubState=exited</span><br />
<br />
I've created a root cron job to run, probably, once a day, to check and restart if neccessary, the services<br />
<br />
For example, for radicale<br />
<br /><span style="color: #b45f06;">#!/bin/bash</span><br />
<span style="color: #b45f06;"># Run with root crontab once each day</span><br />
<span style="color: #b45f06;"># --------------------------------------------------------------------------<br /># radicale shows on reboot:<br /># LoadState=loaded<br /># ActiveState=active<br /># SubState=exited<br />/bin/echo "Checking radicale"<br />/bin/systemctl show radicale.service | /bin/grep -i SubState=running<br />radicale_rc=${?}<br />if [[ ${radicale_rc} -ne 0 ]]; then<br /> /bin/echo "radicale not running"<br /> /bin/systemctl restart radicale.service<br /> /bin/systemctl show radicale.service | /bin/grep -i SubState=running<br /> radicale_rc=${?}<br /> if [[ ${radicale_rc} -eq 0 ]]; then<br /> /bin/echo "radicale running"<br /> fi<br />else<br /> /bin/echo "radicale running"<br />fi</span><br />
It is more difficult to check the sshd error as sshd is started. I'm using a rather dirty hack of checking if apache2 is running and, if not, restart sshd.<br />

The solution I found to work was to have one alias for each ip<br />

This is my /etc/network/interfaces<br />

This also worked on my new Pi with Raspian Stretch after disabling dhcpcd. I wanted to do this as the new Pi is to be my new everything server.<br />

I have no objection to a second referendum regarding leaving or staying in the European Union but with one proviso. All the people who voted to leave but really wanted to stay in the Union are not fit to take part in a decision that decides the fate of everyone else so they would be excluded from voting in the second referendum. This should be easy to implement as the people concerned appear to have already generated a list.<br />
<br />
To keep the excluded happy during the referendum period, perhaps there could be a second questionnaire. This could take the form of, say, a list of clothing manufacturers for whom the excluded prefer to display free advertising on their clothes. The manufacturers could bid for tick boxes on the voting slip and proceeds would be given to the N.H.S.<br />

I was having a really good start to the summer, including 23 points in a 9 hole stableford that cut my Congu handicap by 2. So I went from 25.5 in June to 22.1 at the beginning of August.<br />
<br />
Then a small operation followed by an 8 week golf hiatus.<br />
<br />
Three not very good nine hole games in the UK then off to Barbados for the winter.<br />
<br />
My handicap index in Barbados was 19.2 so played off 20 at Rockley and that was far too low for my post-op. ability. The first game knocked a very good game from last January out of my 20 so my playing handicap went up by one, but that was still far too low. Most of my good scores were in the latter half of my 20 scores so played off 21 for a month.<br />
<br />
There are indications I am getting back into the swing of things. On Thursday, I drove past the yellow marker on the first fairway for the first time this winter. On Tuesday, I scored 2 under handicap but, as it knocked a "3 under" off my record, I expect my handicap to go up to 25 at tomorrow's weekly recalculation.<br />
<br />
The next score to drop of my handicap index is now a 4 under, the last remaining score from last March.<br />
<br />
So, with getting my game back and with last winter's scores all gone, hopefully my handicap has topped out and I can try to get it down again.</div>

<br />
Metro Bank won't give me a contactless card so I want to cut the wires. Presumably the loops around the chip are to pick up power but there seems to be something coming out to the right. Is that the rfid chip to the right of the main chip?<br />
<br />
I am thinking that if I cut through the card across the wireless logo, I should be able to disable it. But I must buy something first to do a before and after test.<br />

And the new algorithm seems to make a complete pig's breakfast of the job.<br /><br />Here are 3 photographs, all taken at f5.6, 30th sec.<br />The first is without auto iso and flash. Iso is 100.<br />The second is auto iso and no flash. Iso is 2200.<br />The third is auto iso and flash. Iso is again 2200. You can see the shadows from the overhead domestic lighting and it seems the camera is trying to use a mixture of lighting, squelches the flash and puts up the iso instead. But the white balance for the mixed lighting does not appear to work. And the iso is ridiculously high.<br /><br />I've taken another photograph where the camera has decided to use f8 and iso 6400, 6400 being the maximum iso I've allowed. That seemed to have been a very daft choice for a combination of settings.<br /><br />The algorithm seems all wrong to me.<br /><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://2.bp.blogspot.com/__eBx6HSSpW8/TSTZgM7rxsI/AAAAAAAAAEY/kWivF5JCvMA/s1600/dsc_0047.jpg"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 212px;" src="http://2.bp.blogspot.com/__eBx6HSSpW8/TSTZgM7rxsI/AAAAAAAAAEY/kWivF5JCvMA/s320/dsc_0047.jpg" alt="" id="BLOGGER_PHOTO_ID_5558806987332634306" border="0" /></a><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://2.bp.blogspot.com/__eBx6HSSpW8/TSTZJ-YUI9I/AAAAAAAAAEQ/S4rBLUWrtbo/s1600/dsc_0049.jpg"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 212px;" src="http://2.bp.blogspot.com/__eBx6HSSpW8/TSTZJ-YUI9I/AAAAAAAAAEQ/S4rBLUWrtbo/s320/dsc_0049.jpg" alt="" id="BLOGGER_PHOTO_ID_5558806605469066194" border="0" /></a><br /><br /><br /><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/__eBx6HSSpW8/TSTauPvOlVI/AAAAAAAAAEw/GG_euJ8UiR4/s1600/dsc_0048.jpg"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 212px;" src="http://1.bp.blogspot.com/__eBx6HSSpW8/TSTauPvOlVI/AAAAAAAAAEw/GG_euJ8UiR4/s320/dsc_0048.jpg" alt="" id="BLOGGER_PHOTO_ID_5558808328115492178" border="0" /></a><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/__eBx6HSSpW8/TSTaW6ur6VI/AAAAAAAAAEo/LTChKoFKw1Y/s1600/dsc_0048.jpg"><br /></a>Alan Cliffordhttp://www.blogger.com/profile/07203284236816302240noreply@blogger.com3tag:blogger.com,1999:blog-13578802.post-89950779186206111052008-10-05T12:18:00.005+01:002008-10-05T12:32:09.579+01:00Man fined for taking photo of woman being sick<a href="http://news.scotsman.com/scotland/Man-fined-for-taking-photo.4558618.jp">Article in The Scotsman</a><br /><br />There seems to have been three crimes committed here.<br /><br />The sheriff is there to uphold the law; he is not there to abuse existing laws to impose his own morality on the public. The photographer did not breach the peace and was not behaving in a disorderly manner but the sheriff is trying to use these laws to bring in a "right to privacy" law by the back door. He should be dismissed from his post.<br /><br />It appears that the photographer was assaulted by the friends. Why weren't they prosecuted?<br /><br />Presumably the police arrested the photographer. It looks like a case of wrongful arrest to me.Alan Cliffordhttp://www.blogger.com/profile/07203284236816302240noreply@blogger.com2tag:blogger.com,1999:blog-13578802.post-26383533795448494942008-09-03T22:42:00.004+01:002008-09-03T22:55:02.026+01:00Nikon photo contest international email problem resolvedI emailed Nikon.
