| Compiling older gcc with newer GCC, why did make stop without errors? Posted: 20 Sep 2021 10:22 AM PDT Boring backround: I am attempting to get msp430 toolchain to aarch64 (64bit arm). I have recently moved from gentoo (constant need to add 32 bit useflags poluting mine portage and then cheking if they are still necessary... necessity to add abi_x86_32 manualy did put the hole gentoo to its knees). After 12 years with gentoo I was looking to move to arch, but with mine Pi4 I got manjaro for 64bit support. I am trying to port msp430 to aarch64. I have got the msp430-binutils to the package,but gcc makes more problem... To the point: WHen attempting to compile the TI's latest (patched)gcc-9.3.1.11, The make stops during the compilation but I cant find the actual errors which caused it.

I dont have another computer (Mine old toughbook was killed in rather spectaculary manner with its metal frame melted in process) and I cant use other peoples computers to the developement level. so I cant compileon older and I am not sure about which level chrooting to intell32bit would work on arm platform.

| meld won't start on Cygwin: No module named 'meld' Posted: 20 Sep 2021 08:39 AM PDT I'm using Cygwin 64 on Windows 10; just updated. Some relevant package versions: - meld: 3.18.0-1
- python3: 3.8.6-1
- python2: 2.7.18-4
I'm also using MobaXTerm's X server (and it works - I can run xclock for example.) When I run meld in a Cygwin bash session (within mintty), I get: Traceback (most recent call last): File "/usr/bin/meld", line 71, in <module> import meld.conf ModuleNotFoundError: No module named 'meld'
Why is this happening, and how can I get meld to properly run? Notes:  |
| Directory w/in file system has more space used than total available in Filesystem? Posted: 20 Sep 2021 07:41 AM PDT Linux newbie here, done some search but cannot seem to come across the answer. I am needing to check the size of a directory in order to do some migration work and ensure the space available is sufficient. Yet I Checked one of my directories which is large in size with a du -h --max-depth=1 NameOfDirectory/
The above gave me the size output for all the folders within that directory and at the end I see it summarizes the total to 5.3T. Which I assume is Terabytes. 5.3T NameOfDirectory/BigDir 8.0K NameOfDirectory/firstDir 8.0K NameOfDirectory/SecondDir 8.0K NameOfDirectory/ThirdDir 547M NameOfDirectory/FourthDir 5.3T NameOfDirectory/
This is interesting and make me curious as the whole filesystem this is on only has a 4.6T of which 3.8T is being utilized. Am i misreading this or is there a better alternative which accurately shows the correct size of a directory?  |
| Linux find and delete file by date at home path Posted: 20 Sep 2021 08:47 AM PDT I run some processes which generate a huge number of output files (log, error, warning etc) at my home directory. To find the output files generated on a specific day, let's say 17 Sept 2021, I tried the following command: find . -type f -newermt 2021-09-17
which is supposed to find all files which are modified on 17 Sept 2021 as referred here, and it does work. However, the command returns not only the output files, but also some hidden files at my home directory such as .history, .viminfo and .cache. Now, if I try to delete all the files I found with find . -type f -newermt 2021-09-17 | xargs rm -f
will the hidden files be disastrously deleted as well? If the answer is yes, how should I change it so that the hidden files will be kept and only the output files will be removed?  |
| Why PID 1 send SIGTERM Posted: 20 Sep 2021 06:57 AM PDT I had this problem for a few days. A process, in this case qbittorrent, will stop after a few minutes. Looking at logs it seems that it just caught a SIGTERM. Alright so I used strace -p {PID} -e 'trace=!all' to debug and I've got: --- SIGTERM {si_signo=SIGTERM, si_code=SI_USER, si_pid=1, si_uid=0} --- --- SIGCONT {si_signo=SIGCONT, si_code=SI_USER, si_pid=1, si_uid=0} --- +++ exited with 0 +++
I cannot figure why PID 1 send a SIGTERM to this process. It used to work a few days ago, I didn't change anything on this system. By the way sytem wide CPU and RAM usage remain low (let's say below 30%). Any idea how to investigate further ?  |
| Why does an IPv6 neighbour router status become STALE? How can I avoid it? Posted: 20 Sep 2021 10:01 AM PDT I have a VM on a host with bridged networking (hence, with its own MAC address). Both host and VM run CentOS. Their network is managed by simple /etc/sysconfig/network-scripts/ifcfg-enpXsY files. IPv4 works just fine. I have assigned an IPv6 address to the VM (the host also has one) which is routed correctly in the data centre. Most connections use IPv4, however (no DNS AAAA entry for the machine yet, still testing IPv6). When I boot up the VM it has full IPv6 connectivity. However, after a while IPv6 connectivity stops working (IPv6 magic?). I have narrowed to problem down to neighbour (ARP/NDISC cache) data: Not working, cannot ping or connect by IPv6 in or out: # ip -6 neighbour fe80::1 dev enp1s2 lladdr 0c:86:72:2e:04:28 router STALE
Fix/workaround to refresh the cache: # ip -6 neighbour flush dev enp1s2 # ip -6 neighbour (empty, as expected)
Then ping6 the host from within the VM to fill the cache: # ping6 2912:1375:23:9a6c::2 PING 2912:1375:23:9a6c::2(2912:1375:23:9a6c::2) 56 data bytes 64 bytes from 2912:1375:23:9a6c::2: icmp_seq=1 ttl=64 time=2.35 ms 64 bytes from 2912:1375:23:9a6c::2: icmp_seq=2 ttl=64 time=0.468 ms ^C # ip -6 neighbour fe80::1 dev enp1s2 lladdr 0c:86:72:2e:04:28 router REACHABLE 2912:1375:23:9a6c::2 dev enp1s2 lladdr 08:21:4b:b7:f8:31 DELAY
IPv6 neighbour/ARP table restored to validity and connectivity is working in and out! So my questions are: - Why does the cache become stale?
- What can I do to avoid it?
Of course I could run those commands in a cron job (how often?) but I suppose that cannot really be needed for IPv6 to work in general?  |
| start command in linux Posted: 20 Sep 2021 08:52 AM PDT I have a custom script which runs on a cPanel server (CentOS 6) which is as below. It starts a service on the specified port which accepts incoming data. It uses start command and runs ok. #!/bin/bash PORT_NUMBER=xxxx echo "Start Time: $(date)" if sudo netstat -altpn|grep xxxx | grep -q 'CLOSE_WAIT'; then echo "Found Close Wait" sudo stop comm sleep 60 sudo stop comm sudo lsof -i tcp:${PORT_NUMBER} | awk 'NR!=1 {print $2}' | xargs kill sudo kill -9 $(sudo lsof -t -i:xxxx) sleep 60 sudo start comm fi if [[ $(sudo lsof -t -i:2010) ]]; then echo "Service Running" else echo "Restarting Service" sudo start comm fi
Which start command produces /sbin/start I have copied this script to a newer server with CentOS 7. When i try to run it, it gives the following error. Start Time: Mon Sep 20 12:09:36 UTC 2021 Restarting Service sudo: start: command not found End Time: Mon Sep 20 12:09:36 UTC 2021
I tried searching for a package to install, which provides the start command. I was unable to find such package. Any ideas which package I need to install on CentOS 7 server. Update The comm job was defined in the /etc/init/comm.conf and was being called as the parameter for the start command. description "Daemon Service running on port xxxx to receive device files" author "xxxxxxxxxx" start on startup stop on shutdown respawn script [ $(exec /usr/bin/php -f /home/xxxxxxx/scripts/comm.php &>> /home/xxxxxxx/scripts/log.txt) = 'ERROR' ] && ( stop; exit 1; ) end script

| scp+ssh+scp in a single connection Posted: 20 Sep 2021 10:03 AM PDT I don't know the nomenclature, but basically our corporate environment is setup with jumphosts so creating an ssh tunnel is really slow. Therefore I'm hoping there is some way to perform these three steps in a single ssh command: $ scp localfile.jar user@server:~/path/ # upload executable $ ssh user@server java -jar path/localfile.jar some argument >path/output.bin # run it $ scp user@server:~/path/output.bin . # download output
This is the way. Is there a way? (The server doesn't have access to my local machine, but perhaps that is stating the obvious.) Thanks!  |
| Creating swap when out of memory Posted: 20 Sep 2021 09:47 AM PDT Out of memory is a common issue and the official OOM is not efficient. Several other programs have been introduced to do the killing job faster. I wonder why there is no approach to creating swap instead of killing. Consider a system with no swap, an OOM program can trigger sudo swapon /swapfile (assuming swapfile exists) instead of killing processes. Are there technical limitations for implementing this idea?  |
| Rename directories based on matching and appending column data Posted: 20 Sep 2021 09:13 AM PDT I want to rename directories based on matching information from columns of the CSV file. For example, the columns in the csv file with repeated some rows looks like this: 1111,ABC1 1111,ABC1 2222,DFG2 3333,FEG1 3333,FEG1 4444,TTG2
The existing directories are with following names: 1111 2222 3333 4444
I want to rename these directories by matching with column 1 and appending the corresponding column 2 information along with it. I read the columns as follows: col1_id=$(awk -F "\"*,\"*" '{print $1}' "$somefile" | sed 1d | awk '!a[$0]++') col2_id=$(awk -F "\"*,\"*" '{print $2}' "$somefile" | sed 1d | awk '!a[$0]++')
I tried to map the columns and append as follows: cnt=${#col1_id[@]} for ((i=0;i<cnt;i++)); do mv "{$col1_id[i]}" "${col1_id[i]}_${col2_id[i]}" done
However, I am not getting the desired output. My output directories should be with names. 1111_ABC1 2222_DFG2 3333_FEG1 4444_TTG2

| Return value vs return status of a coprocess Posted: 20 Sep 2021 07:36 AM PDT I don't understand this sentence about Coprocesses in the bash man page: Since the coprocess is created as an asynchronous command, the coproc command always returns success. The return status of a coprocess is the exit status of 'command'. What is the difference between a "success" return value and a "success/error" (0/non-0) exit status? How differently are they handled by the bash? And how can one catch them to see the difference?  |

| Ping from Linux distros = 20s, ping from Windows/Android = instant. Why? Posted: 20 Sep 2021 09:23 AM PDT I'm hoping this will be an interesting problem for Linux networking aficionados. In summary, I have a new broadband modem/router connected to an ISP offering a 40Mbit/s bandwidth. However, the initial connect to any website using a browser on a Linux distro takes a good 20s whereas on an Android phone or Windows the website opens as quickly as you might expect. A ping command (with domain name) too takes 20s to show ANY output at all (even the ip address). Let's focus on ping: When pinging by ip address there is no issue. A 20s delay only when pinging by domain name the ping delay of 20s shows up even when I try it from a live linux USB - whether it is Manjaro or Linux Mint the delay is seen even if I try on another computer with live-booted Linux ping from the same laptop(s) running Windows returns results practically instantly - even with domains I have never visited before. ping from a terminal on a Pixel 2XL phone running Android returns results instantly the problem exists whether I connect my laptop via wifi or via ethernet cable to the router the same Linux distro on the same laptop, when connected to my mobile hotspot does not have the issue Ping -4 to force IPv4 does not help - the delay is still 20s As suggested by a senior member of the Manjaro forum I tried moving from openresolv to systemd-resolved but that increased the delay to over 2 minutes and I had to roll back the change. Having described ping, let me describe how Firefox works on Linux. The first access to any website takes 20 seconds, but thereafter even if I access a website I have never accessed earlier it opens up as expected - in less than a couple of seconds, However if I close Firefox and open a fresh instance I again have to wait for 20 seconds for the first website I access - even if it is Google. This is as you realize not a "fun" question but a rather perplexing one and almost a showstopper for me. The problem is specifically with the combination of Linux and this new router and I have no idea where to look for a solution.I have of course had a long discussion on the Manjaro forum where I hit a dead end. Thanks very much for reading!

| How to only display the text after the third, first, and fifth comma in this order in Unix? Posted: 20 Sep 2021 07:29 AM PDT I want to display the text after the 3rd, 1st, and 5th comma from a given input text, in that order. Doing cut -d ',' -f 3,1,5 does the job but doesn't keep the order I want. Instead, it displays the text in ascending order: 1, 3, 5.  |
| Boost continually fails to download while using cmake for ethminer Posted: 20 Sep 2021 08:44 AM PDT I've been stuck with this since this morning. Basically I ran into an issue with this cmake .. -DETHASHCUDA=ON -DETHASHCL=OFF command while following this https://medium.com/coinmonks/eth-x-nvidia-x-ubuntu-1980393a36f8 tutorial. Things I know for sure: The problem isn't in the paramaters, I tried without them, I get the same error. I have internet connection. Things I tried: I found a similar problem which had the solution to manually download boost, put it in the destination folder and enable an option to take a local file if there is one (I forgot what it is and I can't find that question thread right now, sorry). This of course did not work for me. I've also seen on their sites that they have changed their download urls, but I have no idea what to do with that information. Here is the relevant message: -- SHA1 hash of /root/.hunter/_Base/Download/Boost/1.66.0/075d0b4/boost_1_66_0.7z does not match expected value expected: '075d0b43980614054b1f1bafd189f863bba6600e' actual: 'da39a3ee5e6b4b0d3255bfef95601890afd80709' -- File already exists but hash mismatch.

When I try to run cmake without hunter with -DHUNTER_ENABLED=OFF I get the following error message: CMake Error at CMakeLists.txt:68 (find_package): Could not find a package configuration file provided by "jsoncpp" with any of the following names: jsoncppConfig.cmake jsoncpp-config.cmake Add the installation prefix of "jsoncpp" to CMAKE_PREFIX_PATH or set "jsoncpp_DIR" to a directory containing one of the above files. If "jsoncpp" provides a separate development package or SDK, be sure it has been installed.
UPDATE: I've been able to manually install the necessary packages and I was able to run cmake .. successfully. However, I have encountered another error when I run cmake --build .

| bash: fdisk: command not found Posted: 20 Sep 2021 08:48 AM PDT I have installed Debian 10 remotely on a server from a live netinstal iso USB over KVM, but then I encounter this strange problem: # fdisk -l bash: fdisk: command not found
However if I use /sbin/fdisk -l , the command executes with no issues. I'm wondering what has caused this and how can I fix it?  |
| Terminal sort command options: sort -k1,1 Posted: 20 Sep 2021 07:24 AM PDT cat input.txt | sort -k1,1
I am trying to figure out what the ,1 part at the end does in this command. input.txt is a 2 column file. First column is some word and second column is the number 1. -k1 tells it to sort by the first column, so alphabetically in this case. What does the second part, ,1 do?  |
| $GDM_USER has no access to $XDG_DATA after manually changing location of $XDG_DATA Posted: 20 Sep 2021 06:52 AM PDT I have a small office with 5 desktops and a server, all of them running on Debian. I have just upgraded the clients to Stretch and see only 1 error in the journal that bothers me: gnome-settings-[939]: failed to create profile from EDID data: failed to save ICC file: Error opening file '/var/data/users/Debian-gdm/icc/edid-93ed9b01fe8febb07668e99b557191e9.icc': Access denied

Back in 2014 I had found a manual to do it like this: In /etc/profile.d/xdg_dirs.sh: if [ "$USER" == "root" ]; then unset XDG_CACHE_HOME unset XDG_DATA_HOME else test -d $XDG_CACHE_HOME || mkdir -p $XDG_CACHE_HOME test -d $XDG_DATA_HOME || mkdir -p $XDG_DATA_HOME fi
In /etc/security/pam_env.conf: XDG_CACHE_HOME DEFAULT="/var/cache/users/@{PAM_USER}" XDG_DATA_HOME DEFAULT="/var/data/users/@{PAM_USER}"
I'm pretty sure this has messed up the correct permissions for the Debian-gdm user, but I don't know how to solve it. I tried creating the dir and giving r+w permissions to both Debian-gdm and the default user-groups, but this didn't work. I also tried exclusing the Debian-gdm user from the above script by adding: if [ "$USER" == "root" ] || [ "$USER" == "Debian-gdm" ]; then
, but that didn't work as well. Any thoughts?  |

| Why is it rm -rf and not rmdir -rf Posted: 20 Sep 2021 09:48 AM PDT I've always been curious why the command for deleting everything in a directory is rm -rf. Why aren't there flags to do the same thing with rmdir? Wouldn't it be more intuitive to use rmdir for directory operations?  |
| Is there logitech gaming mouse programming software for any Linux Distro? Posted: 20 Sep 2021 10:25 AM PDT I happened upon an unopened Logitech G502 programmable gaming mouse. I would like to program buttons to do things like write commonly used lines in programs (which I know is possible in Windows; my college roommate did it earlier this year). The problem is, the device is meant to be programmed by software designed explicitly for Windows. The website download page only offers versions for different versions of Windows. A quick Google search yields nothing useful. Does anyone know if there is Linux/Unix software available for programming the mouse? I am using Fedora 20, but knowledge of any software for this mouse which will run on a Linux OS would be useful. The mouse's defaults work when simply plugged in (scroll, clicking/moving pointer, and page fwd/bkwd).  |
| How to SSH from host to guest using QEMU? Posted: 20 Sep 2021 09:01 AM PDT How do I setup ssh from the host to the guest using qemu? I am able to use port redirection when I boot the VM without any special parameters, as follows: /usr/bin/qemu-system-x86_64 -hda ubuntu1204 -m 512 -redir tcp:7777::8001
But when I try to boot using the following: /usr/bin/qemu-system-x86_64 \ -m 1024 \ -name vserialtest \ -hda ubuntu1204 \ -chardev socket,host=localhost,port=7777,server,nowait,id=port1-char \ -device virtio-serial \ -device virtserialport,id=port1,chardev=port1-char,name=org.fedoraproject.port.0 \ -net user,hostfwd=tcp:7777::8001
I get the following error and the VM does not boot: qemu-system-x86_64: -net user,hostfwd=tcp:7777::8001: invalid host forwarding rule 'tcp:7777::8001' qemu-system-x86_64: -net user,hostfwd=tcp:7777::8001: Device 'user' could not be initialized
Please note that I am able to boot the VM without the -net parameter without any issues, however, I want to setup ssh from the host to the guest. ssh from guest to host works fine as expected. Edit I have tried using -net user,hostfwd=tcp::7777-:8001
as well as -net user,hostfwd=tcp::7777:8001
but still the error persists and the VM does not boot.  |
| How can I set repeat rate of USB keyboard with udev? Posted: 20 Sep 2021 08:38 AM PDT How can I get my keyboard repeat rate to apply to a hotplugged USB keyboard? I made a udev rule to set the keyboard repeat delay and rate, /etc/udev/rules.d/99-usb-keyboard.rules with the following contents: ACTION=="add", SUBSYSTEM=="usb", RUN+="/home/michael/bin/keyboard_settings.sh"
keyboard_settings.sh: #!/bin/bash # Set keyboard repeat delay and rate xset -display :0.0 r rate 250 40
udev seems to see this, using the command udevadm test /sys/bus/usb/devices/3-2\:1.0/ read rules file: /etc/udev/rules.d/99-usb-keyboard.rules rules contain 393216 bytes tokens (32768 * 12 bytes), 37438 bytes strings 31709 strings (264322 bytes), 28154 de-duplicated (230440 bytes), 3556 trie nodes used IMPORT builtin 'hwdb' /lib/udev/rules.d/50-udev-default.rules:11 RUN '/home/myuser/bin/keyboard_settings.sh' /etc/udev/rules.d/99-usb-keyboard.rules:1 unable to create temporary db file '/run/udev/data/+usb:3-2:1.0.tmp': Permission denied ACTION=add DEVPATH=/devices/pci0000:00/0000:00:14.0/usb3/3-2/3-2:1.0 DEVTYPE=usb_interface DRIVER=usbhid ID_VENDOR_FROM_DATABASE=Hewlett-Packard INTERFACE=3/1/1 MODALIAS=usb:v03F0p0325d0102dc00dsc00dp00ic03isc01ip01in00 PRODUCT=3f0/325/102 SUBSYSTEM=usb TYPE=0/0/0 USEC_INITIALIZED=4145997461 run: '/home/myuser/bin/keyboard_settings.sh'
And yet, this doesn't actually change the repeat rate. The laptop keyboard has the correct settings, but the external USB keyboard does not. Is Xorg overwriting the settings after the udev rule is applied? How can I find out? I get this in the Xorg.0.log, indicating that X11 is fussing with things, but none of the rules in /usr/share/X11/xorg.conf.d/ do anything to keyboards.
