| Missing drive in software RAID array after reboot Posted: 19 Apr 2021 10:00 AM PDT I have the Problem that I made a software RAID6-array of 6 HDD's. However, everytime the system gets rebooted the Array becomes inactive and after starting it again it degenerates, were always the same drive is missing (/dev/sde). When I re-add the drive the array reassembles and functions properly again, but I'd like to solve that problem. cat /proc/mdstat (after reboot): Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : inactive sdc[2](S) sdf[5](S) sdd[3](S) sdb[1](S) sda[0](S) 48831523840 blocks super 1.2

| Deploying website backend files to webserver from git repo Posted: 19 Apr 2021 09:57 AM PDT We are trying to improve the management of our website backend files, and are planning to deploy (using git pull) the files from the git repo (hosted on a local (within our organisation) GitLab server) to a test web server, and then in turn from the repo to the live web server (which will be new and starting from scratch, as the current server is approaching end of OS support). We are a very small team and don't have much in the way of resources (time, mainly), but it is likely that at least 2 people will be updating different parts of the website. I am trying to foresee potential issues with this plan and work out how to resolve them. First of all, file ownership. Our previous setup had each of us doing everything as root and we want to avoid this as much as possible. We have created a new unix group for the website files and have added the devops team (and the apache user) to it, with the intention of using setgid to ensure that files can be created and then updated without file permission problems. (What would be even better would be if there were some way that the devops team could write to the files, but that Apache could only read them?) Regarding git itself, I am assuming that having different people using git pull is likely to be problematic, with the files in the .git folder possibly owned by and only accessible to the person whose actions last updated them (unless it is possible to successfully apply setgid to this folder as well?). Is this plan likely to be workable, or are there yet more potential problems that we have not foreseen? Are there other (preferably not very complicated, given our limited resources) ways that we could attempt to do something similar?  |
| gtk name for [, ] and / Posted: 19 Apr 2021 10:10 AM PDT I am trying to change my xfce4 terminal keybindings by editing the accels.scm file. One of the changes I lines I wrote is (gtk_accel_path "<Actions>/terminal-window/next-tab" "<Alt>]"). However, this is not working: it seems that gtk needs me to use some name like "RightSquareBracket" or something of the sort instead of simply "]". The same happens with [ and /. I searched for some list with name-key correspondences for gtk without luck. Do you know where I can find these correspondences? Or at least what are the strings corresponding to [, ] and /?  |

Looking at filesystem I see this: 
The largest file system culprits are the previous versions of CUDA (4.7GB and 4.0GB a piece). I don't understand why Nvidia doesn't remove minor versions upon update but what ever, I don't think I need either 11.1 or 11.2 when I'm upgrading to 11.3. I'm afraid of just straight up removing the files, I've been burned before by CUDA installations that get corrupted overtime to the point of being unusable because of actions like that, I don't know what safe actions I should be doing now to solve this issue so I can actually update.  |
| Merging files on the basis of common data Posted: 19 Apr 2021 09:30 AM PDT I have two csv files File 1 : 799001,8_802,3122,627654
File 2 : 799001,567765,v567575
When i try to merge the two files with column 1 as the key, I can see that the files are getting merged, however column 3 of file1 is not getting printed. My output : 799001,2_802_3122,567765,v567575
Expected output : 799001,2_802_3122,627654,567765,v567575
I tried this : awk -F , 'BEGIN { OFS = FS } FNR == NR { names[$1] = $2; next } ($1 in names) { print $1, names[$1], $2 , $3 , $4 }' file1 file2
Why is column3 not getting merged ?  |
| Setup SD Card Reader on Debian 10 Posted: 19 Apr 2021 09:06 AM PDT I want to use the sd card reader on my ASUS UX501VW-FY144T. Via hw-probe (link) one can see that the sd card is a Alcor Micro AU6621, which isn't configured correct. 
So I updated to the kernel version 5.10.: ~ cat /proc/version Linux version 5.10.0-0.bpo.3-amd64 (debian-kernel@lists.debian.org) (gcc-8 (Debian 8.3.0-6) 8.3.0, GNU ld (GNU Binutils for Debian) 2.31.1) #1 SMP Debian 5.10.13-1~bpo10+1 (2021-02-11)
Now there should be support for this card reader according to github. But on insertion nothing happens. dmesg prints nothing and lsusb, lsblk, lscpi don't list the sd card reader. Any ideas? Thanks in advance! Luke  |
| Debian 10 freezes, possibly related to running Zoom Posted: 19 Apr 2021 08:54 AM PDT I have two computers (henceforth referred to as computer 1 and computer 2, respectively) on which I run Debian 10. On computer 1, I have at two or three times had the computer seemingly freeze up, such that the screen would freeze and the computer would not respond to keyboard input (I was also unable to toggle keys like NumLock and CapsLock). On at least one of these occasions (possibly all, I don't quite remember), I have been running Zoom. The sound has then continued to work, both for myself and for the other participants in the call. In addition, the video from my camera has still worked for the other participants. At first, I though there might be some kind of hardware issue with computer 1. However, I recently had the same problem occur on computer 2. Again, I was running Zoom. The computer seemingly froze and did not respond to keyboard input or mouse movement. However, the sound still worked and the video from my camera still worked for the other participants in the call. There could of course be some kind of hardware issue with both computer 1 and computer 2. Howver, I am more inclined to believe it is software related, since I've had the same kind of issue on two different machines. I am looking for advice on how to troubleshoot the error and suggestions for what might cause it.  |
| Upgrade Fedora 33 to Fedora 34 failed due to insufficient /var space Posted: 19 Apr 2021 08:50 AM PDT I was performing an upgrade from Fedora 33 to Fedora 34 Everything seemed to work, then I did the system upgrade reboot, and that seemed to work too until I got to the login where I got just a black screen. Escaping to shell I saw in the logs errors about lack of disk space in /var and sure it was 100% Foolishly I deleted /var/tmp/* and now I can't boot at all to 34 or 33; I just get the dreaded "Oh snap: something went wrong" I think it still wants to complete the upgrade but it can't. At this point I'd just like to know if there is something I can do to just let it boot to 33 again, or somehow force it to continue the upgrade or wipe out that upgrade so I can start over.  |
| A better way to connect to the VPN with single-use PIN Posted: 19 Apr 2021 08:41 AM PDT At my workplace we are using VPN to connect to our servers. Our VPN system is configured that way that it accepts as a password 8 digits generated by OTP and 4 persistent digits (e.g. 1111) = 12 digits in total. I'm using Debian 10 and OpenVPN. In the very beginning I was using openvpn command directly: specifying all parameters to it to perform the connection. Then I decided to make a life a little bit easier and created aliases in my .zshrc file: # For connecting and checking status after that alias ovpnc="sudo openvpn --config ~/OpenVPN/config/ovpn-client.ovpn --log /var/log/openvpn/ovpn-client.log --daemon | ovpns" # For checking logs alias ovpnl="sudo cat /var/log/openvpn/ovpn-client.log" # For checking status of connection alias ovpns="curl -I --silent <GitLab project URL's> | grep -q 'location: <GitLab project URL>' && (tput setaf 2 && echo 'Connected') || (tput setaf 1; echo 'Not connected')" # For closing connection alias ovpnd="sudo pkill openvpn"
Because I am highly new to bash syntax, any suggestions are also welcome! As time goes by, this is getting very annoying to specify login (it is not short too) and password to just connect to the work VPN, sometimes I need to reconnect to different VPNs or disconnect from it and in one day it can be up to 20-40 reconnections. My questions are: - Is there any way to simplify a process of connection (if it will remember at least login name it will be excellent)?
- Is there an easy way to configure console OTP client? If there is then is there a way to pass its output to OpenVPN client?

| Can an open port be hacked to get access to the command line? Posted: 19 Apr 2021 09:21 AM PDT Assume I run a custom app on an arbitrary port on a linux box - let's say 7890. This is a go language web server. Runs an app on top of HTTP. No HTTPS. It runs as a dedicated but "normal" user with no sudo rights. The firewall rule for this port allows "everyone (world)" to access it. All ssh access is secured and firewall rules allow only access via a set of known IPs. SSH access is configured to allow only key-based access. Is this enough information to answer the following questions: - Can an attacker ever gain access to the command line via that exposed port?
- If the previous question can be answered with "yes, if...", what are the most important things I need to take care of so that the app can't be exploited to get access to the box?
The assumption would be that there are no other known security holes. Obviously I am no security expert. I hope this is enough information to give an informed statement. I assume there are myriads of related issues and no "absolute" yes/no can be given, but maybe some rough idea is enough for me to get an idea. Thanks.  |

| awk: Parsing a textfile by using keywords for the layout Posted: 19 Apr 2021 10:04 AM PDT I want to create a bash script which iterates through a file, one line at a time, and produces a coherent output: example.txt ALBERT some a BRYAN some b CLAUDIA some c DAVID some d ERIK some e ALBERT some a BRYAN some b ERIK some e ALBERT some a BRYAN some b DAVID some d
some notes: - the word count between the tags is varying
- the keywords always appear in the same order
- A complete list of keywords is available and could be specified before hands
Needed output: some a; some b; some c; some d; some e some a; some b;;; some e some a; some b;; some d;
I can easily replace the keywords one by one with a semicolon using sed: sed -i 's/ALBERT/;/g' "example.txt"
How can I use awk to iterate through every line and add the required semicolons if some of the keywords are missing? I suspect one has to introduce some kind of counter?  |
| Can't compile any c/ c++ program, linker problem Posted: 19 Apr 2021 08:27 AM PDT It's my second post here, i have a huge problem which prevents me to study so i have to fix it as soon as it's possible ! My gcc was working fine and i had to work on FairThreads (in C). I downloaded the following archive : Fair Threads As you can see, in /src there's a makeFile, i replaced the second line which was : LIB_DIR = ../lib
by LIB_DIR = /usr/bin/ld and i compiled the makeFile by the command "make" And now, i cannot compile any c/c++ program anymore. Even a hello world program. I got the following error message on the terminal for every compiling attempt : /usr/bin/ld: 2: /usr/bin/ld: Syntax error: newline unexpected collect2: error: ld returned 2 exit status
I have found on the net this solution but it doesn't work for me : sudo apt-get autoremove binutils sudo apt-get install binutils
I also tried to reinstall gcc, when executing : sudo apt-get purge gcc
i got : Des erreurs ont été rencontrées pendant l'exécution : linux-firmware linux-image-generic-hwe-18.04 linux-generic-hwe-18.04 E: Sub-process /usr/bin/dpkg returned an error code (1)
but when i trie a gcc --version it tells me that it is not found. So when i execute the command to reintall it : sudo apt-get install gcc
i also get : Des erreurs ont été rencontrées pendant l'exécution : linux-firmware linux-image-generic-hwe-18.04 linux-generic-hwe-18.04 linux-image-5.4.0-72-generic initramfs-tools E: Sub-process /usr/bin/dpkg returned an error code (1)
but gcc --version tellls that it's installed. Finally, when i trie to compile a program, i got : /usr/bin/ld: 2: /usr/bin/ld: Syntax error: newline unexpected collect2: error: ld returned 2 exit status
I hope that i explained well, and i'll get a solution for this :/, as a computer science student, i can't do anything without gcc :( EDIT 1 : When i try to remove bin/ld by executing : sudo rm -fr /usr/bin/ld;sudo apt-get install --reinstall binutils

OS: Arch linux, lts-kernel DE: Gnome 40.0.0 Wine: Both stable 6.6 and staging 6.6 App: Musicbee can't be installed; foobar previously installed and running Problem: how to get wine to get to the install window instead of quitting before even a single pop up Note: There is no wine icon in the menu for some reason, but I don't think that is important. And there is no popup either when I run winecfg in terminal, all I get is a hanging cursor. Thanks for dropping by!  |
| Why does ed start at the last line? Posted: 19 Apr 2021 08:28 AM PDT Why does ed start at the last instead of first line of a file? Most of ed's behavior makes sense when you remember that it was for interacting with a printer, but not this. Since I believe it reads the whole file into memory, it's not even an IO seek thing.  |
| Passing variable to AWK not working inside a loop Posted: 19 Apr 2021 08:54 AM PDT I have this awk statement that reads a YAML file and outputs a particular value. I need to loop this awk inside a loop where I read a key value from a list of values and pass that key to awk. The YAML file has this structure: abc: NAME: Bob OCCUPATION: Technician def: NAME: Jane OCCUPATION: Engineer
Say I want to get key abc OCCUPATION value of TECHNICIAN, through googling I managed to construct an awk statement that gives what I want > awk 'BEGIN{OFS=""} /^[^ ]/{ f=/^abc:/; next } f{ if (sub(/:$/,"")) abc=$2; else print abc,$1 $2}' test.yml| grep "OCCUPATION:" | cut -d':' -f2 Technician
However passing -v option to awk does not seem to give anything if I use this loop: items="abc,def" for item in $(echo $items | sed "s/,/ /g"); do echo $item; awk -v name="$item" 'BEGIN{OFS=""} /^[^ ]/{ f=/^\name:/; next } f{ if (sub(/:$/,"")) name=$2; else print name,$1 $2}' test.yml| grep "OCCUPATION:" | cut -d':' -f2; done
I get just the debug echos I set out abc def
Where am I going wrong? I thought the variable should be interpreted correctly inside awk? EDIT: Based on steeldrivers comment I have changed the input a little items="abc,def" for item in $(echo $items | sed "s/,/ /g"); do echo $item; awk -v name="$item" 'BEGIN{OFS=""} /^[^ ]/{ f=name; next } f{ if (sub(/:$/,"")) name=$2; else print name,$1 $2}' test.yml| grep "OCCUPATION:" | cut -d':' -f2; done
However now I am getting all values for OCCUPATION printed: abc Technician Engineer def Technician Engineer
I tried to use the ~ operator but I think I am not using it right as it is giving me errors, so I decided to just parse the value directly, but this is giving duplicates :/  |
| Ubuntu - when I plug in my headphone, my keyboard layout is reset to default, how can I stop it Posted: 19 Apr 2021 08:16 AM PDT I set my keyboard layout to a customized one, with setxkbmap. It is started with "Autostart Application"(~/.config/autostart) and is working fine. But when I plug in my Jabra headphone, it is reset to default US QWERTY one. I want to stop that. I see another post How to set xinput properties triggered by udev device connection? Prevent keyboard layout reset when USB keyboard is plugged in but the best answer assumes that the OP just plugs in another new keyboard; I think this is a wrong assumption and this is definitely not my case. I understand it is an udev problem, and a quite bad bug. Ubuntu 18.04. Using udevadm monitor, I see these lines when Jabra headphone is plugged in: monitor will print the received events for: UDEV - the event which udev sends out after rule processing KERNEL - the kernel uevent KERNEL[514.356707] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2 (usb) KERNEL[514.360571] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.0 (usb) KERNEL[514.384326] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.0/sound/card1 (sound) KERNEL[514.384427] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.0/sound/card1/pcmC1D0p (sound) KERNEL[514.384485] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.0/sound/card1/pcmC1D0c (sound) KERNEL[514.384542] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.0/sound/card1/controlC1 (sound) KERNEL[514.384584] bind /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.0 (usb) KERNEL[514.384616] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.1 (usb) KERNEL[514.384645] bind /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.1 (usb) KERNEL[514.384675] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.2 (usb) KERNEL[514.384701] bind /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.2 (usb) KERNEL[514.384730] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3 (usb) KERNEL[514.387245] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3/0003:0B0E:0305.000B (hid) KERNEL[514.387575] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3/0003:0B0E:0305.000B/input/input18 (input) KERNEL[514.444127] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3/0003:0B0E:0305.000B/input/input18/event6 (input) KERNEL[514.444169] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3/0003:0B0E:0305.000B/input/input18/input18::mute (leds) KERNEL[514.444318] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3/usbmisc/hiddev0 (usbmisc) KERNEL[514.444375] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3/0003:0B0E:0305.000B/hidraw/hidraw1 (hidraw) KERNEL[514.444438] bind /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3/0003:0B0E:0305.000B (hid) KERNEL[514.444473] bind /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3 (usb) KERNEL[514.444510] bind /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2 (usb) UDEV [514.967946] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2 (usb) UDEV [514.970785] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.0 (usb) UDEV [514.971920] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.1 (usb) UDEV [514.972737] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.2 (usb) UDEV [514.973022] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3 (usb) UDEV [514.973854] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.0/sound/card1 (sound) UDEV [514.974449] bind /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.1 (usb) UDEV [514.975643] bind /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.2 (usb) UDEV [514.976113] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3/0003:0B0E:0305.000B (hid) UDEV [514.976909] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3/usbmisc/hiddev0 (usbmisc) UDEV [514.979273] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3/0003:0B0E:0305.000B/hidraw/hidraw1 (hidraw) UDEV [514.980161] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.0/sound/card1/pcmC1D0c (sound) UDEV [514.980666] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3/0003:0B0E:0305.000B/input/input18 (input) UDEV [514.980736] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.0/sound/card1/pcmC1D0p (sound) KERNEL[514.980866] change /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.0/sound/card1 (sound) UDEV [514.983803] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3/0003:0B0E:0305.000B/input/input18/input18::mute (leds) UDEV [515.017334] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3/0003:0B0E:0305.000B/input/input18/event6 (input) UDEV [515.019498] bind /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3/0003:0B0E:0305.000B (hid) UDEV [515.020828] bind /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.3 (usb) UDEV [515.790142] add /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.0/sound/card1/controlC1 (sound) UDEV [515.792199] bind /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.0 (usb) UDEV [515.794039] bind /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2 (usb) UDEV [515.796084] change /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3.2/3-3.2:1.0/sound/card1 (sound)

| How to assign a name to the existing anonymous network namespace Posted: 19 Apr 2021 09:22 AM PDT I have a Linux process that creates a network namespace without registering it in /run/netns. The process has also own PID namespace. The network namespace does not have a name and I can see only id of the namespace: # ip netns list-id nsid 0 nsid 1
Is there a possibility to assign a name to the network namespace so I can use convenient ip-netns commands to show and manage the namespace? I have found an article How to access an unnamed network namespace but it does not work for me because my process has own PID namespace so I do not see the process in the root namespace.  |
| Can't install Golang on Solaris via pkg - release/evaluation dependency Posted: 19 Apr 2021 08:22 AM PDT On a new installation of Solaris 11.3 on Sparc hardware, I'm trying to install Golang but am getting the following problem: # pkg install --accept developer/golang Creating Plan (Solver setup): | pkg install: No matching version of developer/golang can be installed: Reject: pkg://solaris/developer/golang@1.7-5.12.0.0.0.122.0 Reason: No version for 'require' dependency on release/evaluation can be found
I'm new to Solaris but have installed a few other things via pkg and am also familiar with other packaging systems on Linux systems (rpm, apt, etc). What am I missing? The missing dependency on release/evaluation doesn't seem to be something I can install, and I've seen a post about 11.4 and FOSS software installs not having nasty "surprises" like 11.3 (which I think I've just found), but I can't see what those surprises are. NB: if it's relevant, I'm not currently using zones/etc, I'm just treating the system as one machine.  |
| Manjaro - how to set in routing table that addresses to internet come out by specific IP? Posted: 19 Apr 2021 08:19 AM PDT I have a connection via VPN with my work. I know that internet connection (for example to 8.8.8.8) goes through my work network (only when I am connected to VPN). How to configure ip tables to force that connections to internet (for example 8.8.8.8) avoid work network ? Using @Julie help in comments I did managed to discover some options:
 Nevertheless, after checking 'Use this connection only for resources...' I can't ping machines in VPN network. Can you tell me how should I deal with it ? I guess that I should click 'Add' and set:
Address = address of some machine in VPN
Netmask = I can get it from ifconfig (in VPN interface)
Gateway - as in case of netmask
Metri - I have no idea ? Am I right ?  |
| How to sharing Android VPN with Linux? Posted: 19 Apr 2021 08:37 AM PDT I have a rooted galaxy note5 with Android 7, and an Asus laptop with Ubuntu 16.04. I like to share my phone VPN connection with my laptop. I tried some apps like VPNTether,DF tethering fix, TetherNet, Pdanet+, etc. but they didn't work! I think I could use the VPNTheter on windows 10 and it worked, but they don't work on Ubuntu! Also I tested two Wi-Fi and USB cable methods. Also I found this method but couldn't understand what it says in numbers 6 and 7 ? 1. You need a rooted device 2. Make sure you have a VPN app, like OpenVPN or DroidVPN ( I use DroidVPN and its the best) 3. Download Terminal Emulator 4. Activate your hotspot and connect to your VPN 5. Launch Terminal emulator and on the first line type "su" (without the quotes) and press enter 6. Copy and paste this to the Terminal Emulator. Make sure to paste to a new folder using Root Browser first and copy to T.E. in the exact format as shown below: iptables -t filter -F FORWARD iptables -t nat -F POSTROUTING iptables -t filter -I FORWARD -j ACCEPT iptables -t nat -I POSTROUTING -j MASQUERADE ip rule add from 192.168.43.0/24 lookup 61 ip route add default dev tun0 scope link table 61 ip route add 192.168.43.0/24 dev wlan0 scope link table 61 ip route add broadcast 255.255.255.255 dev wlan0 scope link table 61 7. That's about it. Also, be sure to make a folder with Root Browser and paste the code there, as this resets after re-boot. It worked on my LG G3 on android 4.4.2

| Recover deleted partition using testdisk Posted: 19 Apr 2021 08:46 AM PDT Last night I was not as awake as I thougt i was and I ended up formatting the wrong drive using GParted..... I thought of testdisk to recover the lost partition but I don't really understand how to use it. First of all Testdisk detect the partition table of my drive as "none" where as it should be detected as Intel (in my opinion)  If I select an Intel partition type and then analyse --> deeper search it showing in the first second of the scan the correct (backup superblock ?) of my "Lacie1To" partition witch used to be the only Ext4 partition occupying all the disk. 
But if I clicked on stop it doesn't show me the partition in the list. So my question, what should I do with this info ?  |

| Getting the current path in .desktop EXEC command Posted: 19 Apr 2021 08:50 AM PDT Im trying to make a .desktop file run a .sh which is stored in the same directory as the .desktop. The whole directory needs to be portable and moved from machine to machine. my run script is run.sh I've tried: [Desktop Entry] Type=Application Terminal=true Name=RunMe #Exec=sh -c "`dirname %k`/run.sh" #Exec=bash -c "export PATH=$PATH:`dirname %k`; bash run.sh;" #Exec=bash -c "export PATH=$PATH:`dirname %k`; sh run.sh;" Exec=bash -c "export PATH=$PATH:`dirname %k`; run.sh;"
But nothing happens when I double click the .desktop file. If I double click 'run.sh' and choose 'run' the script runs fine. If I run the script from the command line with 'sh run.sh' it works fine. Any ideas, even just how I could debug which path its actually trying to run from?  |
| What's the easiest way to find an unused local port? Posted: 19 Apr 2021 08:22 AM PDT What's the easiest way to find an unused local port? Currently I'm using something similar to this: port=$RANDOM quit=0 while [ "$quit" -ne 1 ]; do netstat -a | grep $port >> /dev/null if [ $? -gt 0 ]; then quit=1 else port=`expr $port + 1` fi done
It feels awfully roundabout, so I'm wondering if there's a more simple path such as a builtin that I've missed.  |
