Upgrading Ubuntu with a RAID drive
by Andrew Greig 30 Nov '20

30 Nov '20

Hi all, I have been running extremely well since taking the advice and receiving the support of many on this list. I am grateful those members everyday for its stability. Ed Chan has been an amazing support in creating some backup solutions which have automated the process of achieving efficient data redundancy. I have a Ubuntu 18.04.5 LTS distro with a RAID 1 pair under btrfs.And now I am considering upgrading to another LTS release. Will the commands relating to the RAID survive the upgrade, will the script work from Ed survive the upgrade? In my work as a photographer I find myself in need of GMIC in GIMP, but the latest iteration of GMIC is what I need to recover some work I recently shot. And the latest version of GMIC needs Ubuntu 20.10. Many thanks Andrew Greig

RE: Choosing an NBN RSP

On NBN100/40 FTTN business account, according to Samknows/ACCC speed monitoring, I'm getting average of 96.4/36.8 with peaks in low demand times of 102/38. Now that iiNet's been absorbed by TPG, I might consider Aussie first if choosing from scratch.. > I'll also need to do an equipment upgrade in the near future.

Not sure I want to shave that off, but also not sure I want to turn off DPI. Am curious to hear how other folks have set themselves up. Have heard little bits about EdgeRouter etc.. Right now I'm using an Asus RT-AC5300 with some third party firmware mods.

SSL on LUV server
by Russell Coker 10 Nov '20

10 Nov '20

I've been doing some work on the LUV server and noticed that it was supporting old SSL protocols. I disabled TLS 1.1 as ssllabs will no longer give a rating higher than B to a site that uses it, with that change we get an A+! I think this is no big deal as this only prevents access from Android below version 5.0 (NB Chrome on Android 4.x works fine, it's the Android internal browser that no-one would ever want to use on our site that fails), and some particularly ancient versions of Safari and IE. https://www.ssllabs.com/ssltest/analyze.html? d=www.luv.asn.au&s=46.4.124.163&latest The above URL gives the test results. I disabled all the weaker ciphers that aren't being used. The cipher TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA is weak but is required to support IE11 on Windows versions before 10 and Safari versions before 9. Is it worth keeping? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

trouble with debian mirrors
by bnis＠fastmail.fm 07 Nov '20

07 Nov '20

Hello all, In my /etc/apt/sources.list I have been using the following mirror: deb http://ftp.au.debian.org/debian/ bullseye main non-free contrib The last few days it's returning error messages such as the following: E: Failed to fetch http://ftp.au.debian.org/debian/pool/main/t/tree/tree_1.8.0-1+b1_amd64.deb Unable to connect to ftp.au.debian.org:http: E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? Running the suggested apt-get update also fails, and with -f does too of course. If I look for a package from the packages.debian.org site, when trying to download from ftp.au.debian.org/, it won't connect. However, if I try and get the package from ftp.nz.debian.org/debian, the package downloads succesfully. If, in my sources.list I change from the Australian mirror ftp.au.debian.org/debian, to ftp.nz.debian.org/debian, I get an error message: Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package inxi That is when changing: deb http://ftp.au.debian.org/debian/ bullseye main non-free contrib to deb http://ftp.nz.debian.org/debian/ bullseye main non-free contrib fails. I'm writing to ask if the problem I'm having is common and there's a problem like congestion with the au mirror, and also how to change mirrors in the sources.list so that I can install and update. ben

Old OpenLDAP server and ProFTPD - "bad password" problem
by Peter Ross 06 Nov '20

06 Nov '20

Hi all, My colleagues and I are scratching our heads to figure out what goes wrong when we are setting up a new ProFTPd server and connecting to an older LDAP server (CentOS 5 - we want all refurbished at the end). The new ProFTPd is on Ubuntu 20.04 and uses mod_ldap. We can connect to the LDAP server, getting uid etc., but then it says: 2020-10-22 12:27:22,998 mod_ldap/2.9.4[1510]: bad password for user ftptest It works if we use the "old fashioned way" as our old server had: using nsswitch.conf. Interestingly, the LDAP server gives back, using ldapsearch userPassword:: e0NSWVBUfUFDOTl5RjBhWVNZNmM= When using a system user, I have this: # getent shadow|grep -i ftptest ftptest:ACJJox72N4DZQ:14740::99999:7::: I wonder what the password hash above is, they all start with "e0NSWVBUf" , and whether we are missing anything in the ProFTPd configuration so it 'understands' it. As said, the OpenLDAP server runs on CentOS5, so it is old, very old.. (openldap-2.3.43-3.el5), don't ask me why it's still there ;-) Do you have any ideas what I can do to get ProFTPd working with it? Thank you Peter

Matrix
by Russell Coker 31 Oct '20

31 Oct '20

https://en.wikipedia.org/wiki/Matrix_(protocol) https://en.wikipedia.org/wiki/Element_(software) https://wiki.debian.org/Matrix I've setup a test installation of Matrix for LUV. At the moment I'm not committing to making it an ongoing LUV service, but it seems likely that we will do that. Email me off-list if you would like a Matrix account on luv.asn.au. The "Element (Riot)" client for Android works well as does quaternion in Debian (which incidentally doesn't support A/V). You can chat to me as @etbe:luv.asn.au or use the room luv:luv.asn.au. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

btrfs-convert
by Russell Coker 23 Oct '20

23 Oct '20

It's just been pointed out off-list that the btrfs-convert program I mentioned after the BTRFS training session has been removed and there's only the man page left. Apparently they are going to write a new conversion program. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
