| How to bind multiple hid sub drivers to different interfaces of a single USB-HID device? Posted: 20 Jan 2022 05:51 AM PST Short background on the issue I'm facing. I'm working on implementing simultaneous UART/I2C operation using a usb bridge, the FT260. The chip relies on HID reports to provide these functionalities. Plugged in, the hid-generic driver detects two interfaces, 0 and 1, the first is for I2C and the second is for UART. Currently, I have the FT260 driver supporting I2C only loaded as a module (i.e., hid-ft260) and it works fine. Then the latter takes over hid-generic and I think the usbhid is responsible for that. lsusb -t returns: |__ Port 2: Dev 3, If 1, Class=Human Interface Device, Driver=usbhid, 12M |__ Port 2: Dev 3, If 0, Class=Human Interface Device, Driver=usbhid, 12M
dmesg shows the following during boot-up:
hid-generic 0003:0403:6030.0001: hidraw0: USB HID v1.11 Device [FTDI FT260] on usb-xhci-hcd.1.auto-1.2 hid-generic 0003:0403:6030.0002: hidraw1: USB HID v1.11 Device [FTDI FT260] on usb-xhci-hcd.1.auto-1.2 ft260 0003:0403:6030.0001: hidraw0: USB HID v1.11 Device [FTDI FT260] on usb-xhci-hcd.1.auto-1.2/input ft260 0003:0403:6030.0002: hidraw1: USB HID v1.11 Device [FTDI FT260] on usb-xhci-hcd.1.auto-1.2/input
For UART, I had to use an application that works with the hid-generic. While the driver for I2C can be extended to support UART, maybe as virtual COM port, but it's not that trivial (at least I think) plus I have a working code that I'd like to use and carry on with the rest of the project. When I try to unbind the interface UART using the following command: echo -n 0003:0403:6030.0002 > /sys/bus/hid/drivers/ft260/unbind
I can see the binding is gone. However, when I try to bind the exact interface (if 1) to hid-generic echo -n 0003:0403:6030.0002 > /sys/bus/hid/drivers/hid-generic/bind
I get: -bash: echo: write error: No such device
hid-generic gets loaded automatically (hot-plug) though when I unload the module hid-ft260 using: modprobe -r hid-ft260
It sounds like the usbhid locks to a single sub driver at a time based on PID and VID, but could be something else. If you have insights on bypassing this, that'll be very helpful. Thank you. |
| extract file to generate and rename differenf files Posted: 20 Jan 2022 05:59 AM PST I have a csv (in which firt and second column are separeted by ",") file like this: Column1,Column2 4e,info1 4t,info2 45t,info3 3,info4
I would like to obtained 4 different file, one for each row and the file names are taken from the Column1 while the content from the Column2. my expected output are: filename1 = 4e.smi info1
filename2 = 4t.smi info2
filename3 = 45t.smi info3
filename4 = 3.smi info4
I think that I could generate two different variable, one related to the first column and the other to the second one and use this variable to create new file doing this in loop for all the rows. But I tried this cmd line but it didn't work: while IFS=',' read -r name smile; do write "$smile" "$name".smi; done < InputFIle.txt
Could someone help me please with this challange? Thanks. |
| How to track open() syscalls in FUSE filesystem? Posted: 20 Jan 2022 05:00 AM PST I want to track all open() syscalls of a process inside a FUSE filesystem. Two concerns: Is there any usecase, when open() syscall will not trigger a FUSE filesystem operation? For example syscall will be handled internally by kernel. Which FUSE operations may be triggered after open() syscall? I've found those in libfuse documentation: - open()
- mknod() + create()
- ... any other?

| How to kill all network access to linux iso Posted: 20 Jan 2022 04:24 AM PST I am trying to set up a Linux environment on a laptop that is completely unable to have any network communication from a software angle. No WiFi, No Bluetooth, No Ethernet.(Inbound and outbound) To start I am using bodhi linux (for its small size) as I was having issues adding repositories using slax linux. After making a fresh install there are a number of applications I need to install on the iso before configuring it to be completely offline. The reason for this is from a security perspective to prevent any possible hacks. I know it might seem like a silly question, but I cant seem to find any answer anywhere as my searches keep throwing back links and questions to people asking for help enabling network access. whilst I want to completely kill it. |

| Simple way to send email to Dovecot mailbox from Unix scripts? Posted: 20 Jan 2022 05:34 AM PST I'm looking to send emails to myself from various scripts on my Linux (Debian 10) system. My thought was to install just Dovecot, and not an MTA like Postfix, to avoid the complexity of configuring the MTA. All I want to do is drop myself the odd email from a script, and then connect to my mail server with Thunderbird and pull those emails. I used to run my own email server, however, and the way I sent scripts on there was to use /usr/sbin/sendmail. This binary seems to have been supplied by Postfix, because it isn't there with just a Dovecot install. Assuming I have already set up Dovecot to successfully allow retrieval of email from local user mailboxes via eg. POP3, what's the simplest way (least configuration, basically) for me to send email to those local mailboxes from a unix script? I'd like to avoid installing a full-on MTA, or ideally, anything else at all. I'd like some sort of equivalent to: /usr/sbin/sendmail "to@address.com" <<EOF_emailContent (email here) EOF_emailContent

| How do I alter datestamps of files recursively but only if the existing file doesn't match a particular date? Posted: 20 Jan 2022 04:25 AM PST I have a folder (many files and subfolders, a few hundred gigabytes). I duplicated the folder with rsync, but forgot to preserve the timestamps. The new folder has now had many new files added to it and existing files modified. I need to copy across the timestamps of the old folder to the new folder, but only if the files haven't been modified after Jul 9 2021. I don't think rsync will do it. I think I'll have to use touch -t, but need an efficient way to process all the files. Is there a better way? Or, how can I process all the files and update the timestamps if the files haven't been modified since Jul 9. Thanks. |

I tried booting a Linux Mint live USB and everything works fine. I can launch the desktop environment, watch videos etc. without any issues. It also came pre-installed with Windows and Windows worked fine as well. Since I bought the PC second hand I ran all the bios diagnostics (for unrelated reasons) just to check that it's all okay and all tests passed as well. I also tried switching to linux-lts and that made no difference either :( I've spent quite some time looking into this issue and haven't been able to figure it out. Any help is really appreciated :) UPDATE: After reinstalling Arch from scratch, X seems to be working fine. I haven't ran any of my setup scripts yet (they install packages I use, configure things etc.), so there is likely something wrong there that broke it. I'm going to start manually running parts of that script until I figure out what part broke X, and once I do I'll post an answer here explaining what caused it. |

| Deactivate Linux Sleep/freeze/hibernate state without systemctl Posted: 20 Jan 2022 03:06 AM PST I have a system with a very specific Linux compilation that runs on ARM CPUs. It lacks almost all services (systemctl included) and generally-included software (apt-get, snap, etc.) and it is not connected to the web, so I cannot download anything (I can although send files through scp). The system can be accessed through ssh which is managed by dropbear (or alternatively I can access the system through UART). I work on the system by doing ssh. The problem is that every morning I cannot access it in any way, even though every led is blinking green. It is like the system went into freeze/hibernation/sleep/dunno and all I/Os are deactivated. If I restart the system, everything starts working again. Is there a way I can wake up the system or not make it go to sleep? I need something I can do through vim, like edit some configuration files, etc. (I have root access). Thanks to everyone, Please Help Eventine |
| How to undo/fix autoremove's change to initramfs-tools? (Causes error in Whonix) Posted: 20 Jan 2022 04:18 AM PST I executed sudo apt autoremove to free space in boot. I realized in hindsight that there are better ways to free space. I don't notice any problems on my host os, but when I start Whonix KVM it shows me an error message about being unable to find the command for initramfs-tools. I have to press any key to continue booting Whonix. I don't notice any problem while using Whonix, but I'm not experienced enough to understand what kind of issues the error message could cause. What I've tried: Restarting the computer. sudo apt install initramfs-tools

| Empty login screen with two monitors (lightdm) Posted: 20 Jan 2022 05:07 AM PST I'm using Kali Linux 2020.4 with xfce4=4.16 and lightdm=1.26.0-7. I have two monitors setup: HDMI 1920x1080 (shows up as 2nd, HDMI1 in xrandr) and VGA 1366x768 (shows up as 1st, DP1 in xrandr), using HDMI monitor as primary. First issue: when lightdm login screen shows up after system boot, lightdm takes 1920x1080_60.00 resolution, second monitor works in mirror mode with the same resolution but image gets cropped at 1366x768. Not critical issue but a bit annoying. Probably it's configurable, but I found nothing useful about this on google, stackoverflow, askubuntu and etc. Second issue: when I click lock button (which calls xflock4 as far as I know), both screens turn off. To unlock the computer, I move mouse and screens turn on, lightdm shows, but nothing like lightdm panel on top of the screen, no login form, nothing. Restarting/reloading lightdm doesn't fix it, only reboot helps (but then I lose all running apps, they just get forcibly killed). Very annoying issue. If you want to help, don't focus on the first issue, it doesn't prevent me from working or something like that. Thank you for answer(s). |
| Cannot telnet host from ec2 instance behind a proxy Posted: 20 Jan 2022 05:24 AM PST Let me try to rephrase the whole question as it was not very clear the first time.
I need to understand and workout port forwarding. I have an ec2 instance running behind a proxy server. I need to telnet from my ec2 instance to a server outside, 'in internet' through port (let's say) 1919 . In security groups I have allowed tcp traffic on port 1919 from my ec2 instance to the proxy and back and from proxy to the remote server.
To be able to telnet from my ec2 instance to remote server, i think i will have to port forward 1919 in proxy to be able to get to the remote server. I tried it with
iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 9093 -j DNAT --to *ipaddofEC2*:1919
iptables -A FORWARD -p tcp -d --dport 1919 -j ACCEPT
In my squid I have :
acl servicebus_port_9093 port 1919 and
http_access allow allowed_source_hosts allowed_messaging_sites servicebus_port_9093 and
acl allowed_messaging_sites dstdomain .servicebus.windows.net(remote host's url finishes with windows.net)
Still I have not been able to telnet from my ec2 to remote server. Ps. ip forwarding is on in proxy and I tried to tcpdump in proxy while trying to telnet from my ec2 instance to remote server but I get nothing. (I dont know much about tcpdump) I get timeout error. |
| createrepo and yum update with new rpm files, metadata? Posted: 20 Jan 2022 04:03 AM PST So I [almost] know how to update an offline rhel/centos 7 system, I am using a second identical system which is registered with RHN and other repositories. In /etc/yum.conf I have keep_cache = 1 and I have 1000+ rpms under /var/cache/yum/x86_64/7Server/<repo>/packages/ update: forgot to mention i also am doing /etc/yum.repos.d/local.repo having file:///root/localrepo On the first time, if I put simply put ALL rpm's under one folder /root/localrepo/ for example then do createrepo /root/localrepo then a yum update works fine. In the future, on my RHN connected system I get new rpm's, I move and add them to my offline system under that /root/localrepo but a yum update does not automatically see them. What is the correct usage of createrepo then to make yum update work as expected on this offline system? |
| curl request to IPv6 localhost gets stuck Posted: 20 Jan 2022 04:51 AM PST A docker container of mine exposes a HTTP interface on port 8500, which is mapped to host port 8500. It is not IPv6 enabled. This still means, I should be able to access it at localhost:8500. IPv6 is preferred, so I end up with a request to [::1]:8500. This one gets stuck, it never returns. Reproducing this with curl, this command gets stuck: curl -g -6 "http://[::1]:8500"
curl's --verbose option reveals nothing, neither does --ascii-trace. At the same time, a request to IPv4's localhost succeeds: curl http://127.0.0.1:8500
giving me the expected HTML. If I run an IPv4 HTTP server on loopback, using python -m SimpleHTTPServer 4001
then I get lots of HTML for IPv4's localhost curl http://127.1:4001
and a proper connection failure for IPv6: curl -g -6 "http://[::1]:4001" curl: (7) Failed to connect to ::1 port 4001: Connection refused
Things to note: Docker 1.7.1. IPv6 is not enabled for the container, hence there are no IPv6 iptable rules. (ip6tables -v -L gives nothing) My question is: Why does the request get stuck, and doing what? |
| Delete trailing commas in line Posted: 20 Jan 2022 03:32 AM PST How do I delete a set of trailing commas in bash: a,b,c,d,,,, 1,2,3,,,,
Desired Output: a,b,c,d 1,2,3
Tried doing this: grep "5628" test.csv | sed 's/,*$//g'
but it doesn't work. The file originally came from a Windows machine. |
| grep: input file 'X' is also the output Posted: 20 Jan 2022 04:07 AM PST I use ubuntu 14.4, and been attempting to redirect the output of grep command to a file, but I keep getting this error: grep: input file 'X' is also the output
I run the following command: grep -E -r -o -n r"%}(.*){%" > myfile
As the error states, it seems that somehow it's interpreting the input and output as same name/obj. I searched but couldn't find what exactly is the problem?! |
| What does "Cannot make/remove an entry for the specified session" mean? Posted: 20 Jan 2022 03:37 AM PST Instead of logging me in, PAM greets me with the message "Cannot make/remove an entry for the specified session" after I enter the password. What entry is it talking about (and what session)? The string with the error message is found in libpam.so.0(.83.1). My system is based on binaries from Fedora release 20 (Heisenburg). How can I troubleshoot PAM to figure out what is needed to successfully login? I have no syslog (and no persistent disk, only an initramfs). Updates: SELinux is Disabled. I am more than willing to replace the entire PAM config with something simple that allows login (normal user and root) on the virtual consoles only. Source code from Linux-PAM-1.1.8, libpam/pam_strerror.c reveals that the message comes from the error code PAM_SESSION_ERR, which can be caused by all sorts of internal problems, such as memory allocation error or failure to locate the users home directory. So much for trying to interpret the error message. :-(
Below are my config files based on the comment indicating /etc/pam.d/login as a starting point: (I have also tried removing all lines containing pam_loginuid.so without any noticeable difference)

| how to set crontab PATH variable Posted: 20 Jan 2022 03:28 AM PST I had a problem running a script from crontab. After some research I understood the problem was because PATH parameter doesn't include /sbin. I looked what it does include in /etc/crontab: PATH=/sbin:/bin:/usr/sbin:/usr/bin
As a test - simple cron job to print the PATH variable: * * * * * echo $PATH &> /root/TMP.log
the output is: cat /root/TMP.log /usr/bin:/bin
I don't understand this behaviour... How do I set the PATH variable..? Or better - how to add paths to it? |

| WiFi not working - wlan0 FAILED Posted: 20 Jan 2022 05:01 AM PST My Arch (3.6.5-1) is exhibiting a rather peculiar problem: when wifi is set up, all logs indicate that the setup was successful and that the interface is up and functional. However, when attempting to access a website (or execute ping) all requests time out (despite that connection is reported as working and signal at 63% strength). This tends to happen randomly after laptop is switched on - after some time the connection usually starts working and does not break until next shutdown/suspend.
