[arch-general] hostapd + ap_isolate
by Erich Eckner 24 Oct '21

24 Oct '21

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi fellow-archers, I'm running a software accesspoint with hostapd for several years now. Since some weeks, clients cannot talk to each other directly anymore, also IPv6 broke (the latter might be related, but I'm currently trying to solve the former issue). Unfortunately, I cannot assure, that both happened at the same time. Also, I cannot correlate it to any updates or config changes. The tech stack is: + hostapd (spans two wifi: a normal and a guest net) + dhcpd (for ipv4) + radvd (for ipv6) + iptables (for routing) /etc/hostapd.conf: - ---8<---8<---8<--- bssid=bd:fe:0d:7e:80:37 driver=nl80211 logger_syslog=-1 logger_syslog_level=2 logger_stdout=-1 logger_stdout_level=2 ctrl_interface=/run/hostapd ctrl_interface_group=0 ssid=VzEbpU-wwrtw8f country_code=DE hw_mode=g channel=6 beacon_int=100 dtim_period=2 macaddr_acl=1 accept_mac_file=/etc/hostapd/accept auth_algs=3 ignore_broadcast_ssid=0 wpa=2 wpa_psk=619f85f482f85d30ac69022edaabce188b4edb82910c1e40f40837e4e6599437 wpa_pairwise=CCMP bss=wlp0s12_0 ssid=RmH bssid=29:9a:f9:b2:d9:02 wpa=2 wpa_passphrase=K6VHcvEy wpa_pairwise=CCMP macaddr_acl=0 - --->8--->8--->8--- ipv4 works fine in the following directions: + from access point to any client and vice versa + from any client to any permitted target beyond the access point but it fails between wifi clients directly. The only config change, which I did within the last 6 months, is adding the second wifi on wlp0s12_0. However, I'm pretty sure, that at least IPv6 was not immediately broken. Ipv4-routes and -addresses on the clients look fine, tcpdump shows no packages when trying to ping other wifi clients (is it normal to not see outgoing packages in case of failure? - seems strange, but was the same, when pinging some bogus address from the access point). Originally, I added "ap_isolate=1" to the config of wlp0s12_0 to isolate guest wifi clients from each other - and I'm pretty sure, I did test it, and it did work (and did not break connectivity between wlp0s12 clients). However, during testing now, I even removed that directive without success. Does anyone have an idea, where else I could look? regards, Erich -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEE3p92iMrPBP64GmxZCu7JB1Xae1oFAmFzIM0ACgkQCu7JB1Xa e1ozRhAAoXDEs1qUVCDQvP7o5XZlpGRi59imJH7ZhLABxiuKFZ2YhUoTHTX061lX lgbRSZMVAFEjD6x8Hz/uu0NvB+dYf/+W+cF6r2bRN8JXQ7UOb5qzN3CG9pt2H4gg reYYdwS7VH4U7WrdLZvshqRselcZ+x6c0vrpIiX8ni1c3w+hzEgsZ/1m9QMoy7DR 58xeAtkw879AxltjMyJyhYJT3CSjXzZ330sTpukpS7l9v8shs8JQteGckv0WH4q0 KAXW+H0MtXfDIJIwYDVxWV+5CzMeLLLZ5HTYz+U8mC4HZ6iNQ8FRKqJ6GZGZ/t7W MTNMt9V0qx2ewkAPll+u0JJKoVOOiMqqLPeuGwSTS4Vo5oc9tI7zmYC4GOi9Slsp 6WPoF1OT109KDvoWZS8dEadpMb9Pmv3HlWEo/0k5lydqTW3Ef/+8Etcf0YEoI5sf 1HCkntkeqLIUf6EAH0zqm+reebXXuOt5saWbmRUxGRvQijQOm6M5Q9QvoEqOMeQw fpVVH+2IAzN/m0DPvkiA/kUev2Gho2WRWCe0DvyZ15t4VzngXmvPIjO40Dh8w/Z1 N5sgRVDFATC+ciIestfKGe8anC9X3NO7xrQ+AhLIg2PXcZSkuYbpOJKWvMfCtJ91 2+gyoPqgh/6CXhR1tLa5Ttun9FbCSRVitVDmHg5JHUbhe4Zmz+4= =UNVM -----END PGP SIGNATURE-----

[arch-general] unable to login to win7 and win2008srv after samba DC update to 4.15
by Łukasz Michalski 20 Oct '21

20 Oct '21

Hi, I had to revert my samba DC after upgrade to 4.15. win7 and win2008srv R2 have problems login, win10 and linux clients seems to works fine. There are more reports about this problem on samba mailing list [1]. Consider locking samba to latest 4.14 if doing upgrade of DC. Regards, Łukasz [1] https://lists.samba.org/archive/samba/2021-October/237566.html

Hi everyone, I am unable to launch nfs server. It misses the scripts as mentioned in log: .... systemd[166856]: nfs-idmapd.service: Failed to locate executable /usr/sbin/rpc.idmapd: No such file or directory .... systemd[166857]: nfs-mountd.service: Failed to locate executable /usr/sbin/rpc.mountd: No such file or directory .... systemd[166858]: nfsdcld.service: Failed to locate executable /usr/sbin/nfsdcld: No such file or directory .... systemd[166859]: rpc-statd.service: Failed at step EXEC spawning /usr/sbin/rpc.statd: No such file or directory .... I guess some packages are missing or not properly installed/configured. Any help would be appreciated, Mark P.

[arch-general] Ansible Testing
by Silvio Siefke 14 Oct '21

14 Oct '21

Hello, I have read about ansible and some stuff I managed with it. The idea with roles I find interesting special with VPN / NFTABLES jobs. It make it easier to stay in view :) But I ask me is there a way to test the role system before deploy it real? Thank you for advice Silvio

Re: [arch-general] arch-general Digest, Vol 204, Issue 3
by Daniel Venturini 12 Oct '21

12 Oct '21

Hi, Pete One day I did something similar to it. I had four partition: */boot/efi* */ # /dev/sda2* */home # /dev/sda3* */tmp # /dev/sda4* and my goal was to completely move my partition */home* after */tmp* and increase */* partition with the new /home's free space. I did it in a simple way: I moved the contents of / and /home to other partitions, then I joined old / and /home and I moved all contents of old / to this new partition. Let's go: I booted my laptop within a live usb and I created two new partitions (sda5, sda6), mounted them and moved all contents*:* # mounting things (you can create sda5 and sda6 either with fdisk, cfdisk or even with gparted) mount /dev/sda2 /tmp/root mount /dev/sda3 /tmp/home mount /dev/sda5 /tmp/root-tmp # partition that I created now mount /dev/sda6 /tmp/home-tmp # partition that I created now # moving contents mv /tmp/root /tmp/root-tmp mv /tmp/home /tmp/home-tmp # I highly recommend you to format both partitions that are going to be joined mkfs.ext4 /dev/sda2 mkfs.ext4 /dev/sda3 # joining / and /home # to do it, use *fdisk* to delete both (/dev/sda2 /dev/sda3) and create a new one # or use *cfdisk* to increase /dev/sda2. Suppose you're going to use fdisk (it was what I used): *umount /dev/sda2* *umount /dev/sda3* *fdisk /dev/sda* *> d # delete partition* *> 2 # partition /dev/sda2* *> d* *> 3 # partition /dev/sda3* *> n # new partition (fdisk will join free space on old /dev/sda2 and /dev/sda3)* *> 2 # probably 2 due to /dev/sda2* *> Enter 2x* *> p # print new partition scheme to verify* *> w # write change; JUST DO IT WHEN YOU'RE SURE ABOUT YOUR CHANGES.* # now, mount your new partition and move all content: mount /dev/sda2 /tmp/root mv /tmp/root-tmp /tmp/root # move home files too: mv /tmp/home-tmp /tmp/root-tmp # root-tmp is your new home partition on /dev/sda5 # finally, just update the partitions UUID on /tmp/root/*etc/fstab*: blkid | grep sda2 # looking for your new / partition UUID blkid | grep sda5 # looking for your new /home partition UUID # get both UUID and update them on your fstab file on /tmp/root/etc/fstab # I don't remember exactly, but maybe you need to update your grub: grub-mkconfig Once done, I restarted and all things were working well. If you really want to try it, *I highly recommend you to test it before* on a VM or something like that, unless you know what you are doing. I hope it can fit your problem :).

[arch-general] Error setting up a HP all in one device
by sysadmin＠bsd.com.mx 04 Oct '21

04 Oct '21

Hi everyone, I am trying to set up a MFP 125a (all in one HP device), and usually just installing CUPS + HPLIP detects and configure this kind of devices, however in this case I am able to use the printer but not the scanner. The printer it is detected correctly and works fine, but keep getting an I/O error whenever I try to use the scanner. The device is recognized by lsusb like: Bus 001 Device 005: ID 03F0:222a HP, Inc LaserJet Pro MFP M125nw And scanimage -L and sane-find-scanner recognize it like: device `hpaio:/usb/HP_LaserJet_Pro_MFP_M125a?serial=CNB6F0568K' is a Hewlett-Packard HP_LaserJet_Pro_MFP_M125a all-in-one found USB scanner (vendor=0x03f0 [Hewlett-Packard], product=0x222a [HP LaserJet Pro MFP M125a]) at libusb:001:005 Doing a little research got here: https://evilshit.wordpress.com/2012/09/23/how-to-install-and-configure-hp-p… where indicates that uncommenting the #hpaio line in the /etc/sane.d/dll.conf would help, but it doesnt have that line :( Does anyone have seen something like this? any good tips or links for settiing this AIO device? uname -a: Linux archlinux 5.10.69-1-lts #1 SMP Sun, 26 Sep 2021 12:30:37 +0000 x86_64 GNU/Linux Best Regards Adriel C.

[arch-general] archlinux-java script in java-common package
by 山田ハヤオ 30 Sep '21

30 Sep '21

The archlinux-java script in the java-common package has a lot of code that is inappropriate as a Bash script. (ShellCheck prints a lot of errors.) I have created a patch that fixes these errors with minimal changes. I put the patch on GitHub Gists because it collapses for some reason when I send the patch by email. all.patch is a patch that contains all the changes, and the other files split the changes by function. This is my first time sending a patch to a mailing list, so there may be something wrong with the way it is sent. Patch https://gist.github.com/Hayao0819/bacccc3eebeab73159001f60c9d35a43
