[arch-general] HTTP spam from China
by Juha Kankare 28 Feb '19

28 Feb '19

I'm getting a lot of connections from China it seems. Whenever I check my journalctl, it's an andless wall of nginx complaints about a single ip spamming requests fro different php files. This happens with hundreds of ip's, and tens of times daily. Has anyone else been hit by this. I already made a shellscript to block all connections from China, but I'm curious as to why this happens, and if anyone else has had the same problem.

[arch-general] /var/run vs /run in systemd unit files
by Genes Lists 28 Feb '19

28 Feb '19

I've noticed warnings from systemd about changing systemd files to reference /run instead of /var/run. I'm not sure if this is upstream or arch or both? I see it for things like: rpc-statd (from nfs-utils) dovecot saslauthd chronyd There may well be more. gene

[arch-general] HDMI audio input - HDMI microphone
by Neven Sajko 27 Feb '19

27 Feb '19

Hi, I am designing a digital microphone that should send PCM (LPCM) data to a PC, and I am new to electronics. My first thought for the connection type to interface with the PC was of course USB, but then I figured that HDMI is an alternative more suited to digital audio data, and maybe simpler to work with. But how to get at audio data through HDMI on a Linux system, if it is even possible? I do not mind writing a kernel module if it would not be too complicated. My CPU is i5-8300H with Intel® UHD Graphics 630. Regards, Nsajko

[arch-general] Crashes in FF 65.0.1
by Peter Nabbefeld 27 Feb '19

27 Feb '19

Hello, my Firefox windows randomly crash - is it because of Xorg, Xfce or Firefox? Does somebody else have noticed this behaviour? When I don't do anything at my laptop (and it seems to happen only if I don't do anything at it), after a while when I want to do sth. in the browser again, it doesn't work properly any more. It seems, as if the JavaScript engine would have crashed for the tab or window: As soon as I enter sth., the GUI is corrupted, i.e. layers are shown at the wrong place in an order I cannot do any editing any more etc. If I try to close the tab, the GUI stays unchanged or just the layers of the closed tab are somehow changed, but it seems as if the tab were still active. Re-opening the tab from history results in a blank window (though the correct is shown in the address bar). As I said, it seems to be because of the JavaScript engine, but I'm not sure, yet. Another issue I have is about atlassian: When I open a link, usually a login page is shown. Instead, FF crashes completely. Any idea? Kind regards Peter

[arch-general] What update left mandb scrambled?
by David C. Rankin 26 Feb '19

26 Feb '19

This was odd, $ apropos memcmp memcmp: nothing appropriate. In fact, no man pages were available (checked 2 arch installs). I ended up having to rebuild the database with 'mandb' and now all is well. My question is -- what did this? It must have occurred in the last couple of days. -- David C. Rankin, J.D.,P.E.

[arch-general] Libreoffice fresh not starting
by Friedrich Strohmaier 24 Feb '19

24 Feb '19

Hi community, Since Libreoffice 6.2.0 libreoffice-fresh refuses to start. No Problems with libreoffice-still. As I could not find other reports I assume this beeing a local problem. Message: Fatal exception: Signal 11 Stack: /usr/lib/libreoffice/program/libuno_sal.so.3(+0x3b804)[0x7f4125a5b804] /usr/lib/libreoffice/program/libuno_sal.so.3(+0x3ba25)[0x7f4125a5ba25] /usr/lib/libc.so.6(+0x37e00)[0x7f412578ae00] /usr/lib/libreoffice/program/libuno_cppu.so.3(+0x141e6)[0x7f4124ec41e6] /usr/lib/libreoffice/program/libuno_cppu.so.3(uno_type_any_assign+0x98)[0x7f4124ec3838] /usr/lib/libreoffice/program/libutllo.so(+0x6a9c1)[0x7f41228049c1] /usr/lib/libreoffice/program/libutllo.so(+0x6b735)[0x7f4122805735] /usr/lib/libreoffice/program/libutllo.so(_ZN3utl10ConfigItemC2ERKN3rtl8OUStringE14ConfigItemMode+0x7e)[0x7f41227f5c6e] /usr/lib/libreoffice/program/libutllo.so(+0xc640a)[0x7f412286040a] /usr/lib/libreoffice/program/libutllo.so(_ZN19SvtSysLocaleOptionsC1Ev+0x128)[0x7f41228619f8] /usr/lib/libreoffice/program/libvcllo.so(_Z7InitVCLv+0x1a8)[0x7f4122483b68] /usr/lib/libreoffice/program/libvcllo.so(_Z10ImplSVMainv+0x126)[0x7f4122485266] /usr/lib/libreoffice/program/libsofficeapp.so(soffice_main+0x99)[0x7f41259b63a9] /usr/lib/libreoffice/program/soffice.bin(+0x102d)[0x55fd4308a02d] /usr/lib/libc.so.6(__libc_start_main+0xf3)[0x7f4125777223] /usr/lib/libreoffice/program/soffice.bin(+0x106e)[0x55fd4308a06e] Bugreport: https://bugs.archlinux.org/task/61701?project=1&string=libreoffice-fresh Any ideas on this? -- Friedrich

[arch-general] pambase update now requires explicit service files in /etc/pam.d/ - dovecot affected
by David C. Rankin 24 Feb '19

24 Feb '19

All, With the latest change to pambase, e.g. https://git.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/pam… if you have services that rely on pam authentication, such as dovecot, etc.., you will find that your applications an no longer authenticate using pam until you install a specific pam service in /etc/pam.d for that application, e.g. https://wiki.archlinux.org/index.php/Dovecot#PAM_Authentication I recall seeing something about this change coming earlier, but this was the first update where something stopped working as a result. So add whatever additional files you require to /etc/pam.d/ Thankfully the journal messages are good in pointing out the problem. -- David C. Rankin, J.D.,P.E.

[arch-general] pambase in testing breaks email
by Genes Lists 24 Feb '19

24 Feb '19

pambase 20190105.1-1 caused bad failure for email. The error I saw immediately was from postfix failing to authenticate users via saslauthd which in turn blames pam. Downgrading back to 20171006-1 restores email funtioning ok. Logs say: saslauthd[22214]: pam_warn(smtp:auth): function=[pam_sm_authenticate] flags=0x8000 service=[smtp] terminal=[<unknown>] user=[lists] ruser=[<unknown>] rhost=[<unknown>] saslauthd[22214]: DEBUG: auth_pam: pam_authenticate failed: Authentication failure saslauthd[22214]: do_auth : auth failure: [user=lists] [service=smtp] [realm=] [mech=pam] [reason=PAM auth error]

[arch-general] pambase - creating needed files for apps with normal user auth - pam_unix.so?
by David C. Rankin 24 Feb '19

24 Feb '19

All, After the pambased defaults change, I thought I had gotten everything fixed, today scanning to server via vsftpd issued: Feb 19 12:19:49 phoinix vsftpd[8652]: pam_warn(ftp:auth): function=[pam_sm_authenticate] flags=0 service=[ftp] terminal=[ftp] user=[sharp] ruser=[sharp] rhost=[192.168.7.20] My question is what do I put in /etc/pam.d/vsftpd? Looking at some of the other entries, it seems I can do something with pam_unix.so like screen: $ cat screen auth required pam_unix.so or $ cat dovecot auth required pam_unix.so nullok account required pam_unix.so Since my user (the copier) has a normal Unix account and password, is there any benefit to using the dovecot style with both "auth required" and "account required" or is the "auth required" sufficient like screen uses? -- David C. Rankin, J.D.,P.E.
