| How to use curl to access a webpage behind a login form? Posted: 30 Aug 2021 10:19 AM PDT There is this webpage I'm trying to scrape but it is behind a login form that needs user/password.
I used Firefox debug mode to find HTTP requests. Upon entering the credentials, there is a POST request which return a set-cookie in Response Headers. There is subsequent GET that uses this cookie (instead of user/pass) to finally access the actual page. I want to fetch that cookie via curl in command line.
I tried to replicate what Firefox did with Copy as cURL command on POST. It forms the curl request (with user/pass inside a --data-raw switch and a short ASP.NET_SessionId inside a -H 'Cookie: ....
Problem is, it does not return any headers. The returned HTTP website indicated something went wrong.
Now, in forming up the --data-raw, there are fields like __VIEWSTATE, __VIEWSTATEGENERATOR and __EVENTVALIDATION which seem to change on each GET of the login page. I filled them up via a little scrpting. It didn't fix the issue. I'm using the copied curl command from firefox alongside -c cookie.txt -D - -v ...It does not print the cookie in headers or dump the cookie in the file.  |

| PPP null modem Raspberry Pi to Windows 10 Posted: 30 Aug 2021 09:22 AM PDT I have successfully setup a PPP connection between a Raspberry Pi 3B (Raspbian Buster) and Ubuntu (20.03.2 LTS). I would like to do the same between Raspberry PI and Windows 10. The serial connection is done using a Silicon Labs CP210x USB to UART Bridge. On the Raspberry PI I run: sudo pppd /dev/ttyS0 57600 10.0.5.2:10.0.5.1 local noauth debug nodetach dump nocrtscts persist maxfail 0 holdoff 1 On Ubuntu I run: sudo pppd /dev/ttyS0 57600 10.0.5.1:10.0.5.2 proxyarp local noauth debug nodetach dump nocrtscts passive persist maxfail 0 holdoff 1 The works well and I am able to ping from both sides and I'm using mqtt to pass data between the two. I used the following instructions to setup a Windows 10 laptop instead of a Ubuntu laptop. But it fails with error 777. Configuring Windows Dial Up Networking Installing and configuring a PPP null-modem connection Does anybody have instructions for the Linux to Windows PPP null modem that works.  |

| How to split partition /dev/sda on Ubuntu Posted: 30 Aug 2021 09:26 AM PDT I'm figuring how can I split partition of /dev/sda1/ into /dev/sda1 and /dev/sda2 of my Ubuntu virtual box. Right now, every time I create a new instance of Virtual Server with vagrant, I allocated 40GB of disk space to it and all of the disk spaces is alloted to /dev/sda1 I need a way to split /dev/sda1 partition into 2 with terminal (remote ssh). So what I've tried so far is // Step 1 root@server-1:~# fdisk /dev/sda // Step 2 Delete sda1 Welcome to fdisk (util-linux 2.34). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Command (m for help): d Selected partition 1 Partition 1 has been deleted. // Step 3 Create 2 new Partition Command (m for help): n Partition type p primary (0 primary, 0 extended, 4 free) e extended (container for logical partitions) Select (default p):p Partition number (1-4, default 1): First sector (2048-83886079, default 2048): Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-83886079, default 83886079): 61440000 Created a new partition 1 of type 'Linux' and of size 29.3 GiB. Partition #1 contains a ext4 signature. Do you want to remove the signature? [Y]es/[N]o: N Command (m for help): n Partition type p primary (1 primary, 0 extended, 3 free) e extended (container for logical partitions) Select (default p): p Partition number (2-4, default 2): First sector (61440001-83886079, default 61442048): Last sector, +/-sectors or +/-size{K,M,G,T,P} (61442048-83886079, default 83886079): Created a new partition 2 of type 'Linux' and of size 10.7 GiB. // Step 4 and last step is write it to disk Command (m for help): w
So this way works as I want, but if I ran a fsck on /dev/sda1 I get an invalid checksum on the filesystem and whenever I rebooted the vm, the SSH refused to connect. It didn't even respond. Is what I do correct ? is the partition corrupted ? is there any way to fix it ?  |

I have seen few such issues but none of them had a solution. I am considering trying kernel update to 5.8 or disabling radeon as the last step. Everything except this random shutdown issue works pretty well so any suggestion to fix this bug would be welcome.  |
| Are there any other standard ways of bringing network interfaces up at boot, apart from using /etc/network/interfaces? Posted: 30 Aug 2021 08:25 AM PDT I'm working with a Yocto based embedded system and I want all external network interfaces to default to being disabled at boot. Normally, I'd assume that they go up at boot because /etc/network/interfaces has an auto <INTERFACE_NAME> line in it but that doesn't seem to be the case. In fact, there is no mention of the interfaces in question there. I've searched far and wide for the culprit responsible for turning those interfaces off but I'm running out of ideas. Are there any other standard tools which could be bringing network interfaces up at boot?  |

| Show month of a file's creation (Grouping files by quadrant of creation) Posted: 30 Aug 2021 10:02 AM PDT I'm trying to group files by the quadrant of their creation. What I'm trying to do is determine when a file was created - for example, if I had a file that looks like this: -rwxr-xr-x 1 root wheel 208 Aug 30 16:24 q.sh
I'd like the output to be nothing but the month it was created - in this case, 8. Once I figure this value out, I can toss it into a simple case statement which will sort it - currently I came up with this: #FILE_DATE would be the value I figure out above case $FILE_DATE in [1-3]) echo "Quadrant 1" ;; [4-6]) echo "Quadrant 2" ;; [7-9]) echo "Quadrant 3" ;; [10-12]) echo "Quadrant 4" ;; esac
I've tried using the stat command, as well as filtering output of ls, but have not figured out how to do this reliably. Any help would be greatly appreciated. Thanks!  |
| Keeping two folders in sync with rsync Posted: 30 Aug 2021 08:51 AM PDT I have two external drives. One of the drives is named "drive2" and it contains a folder named "Music." This folder has the following structure: drive2/ /Music/ Pink Floyd/ 1982 - Album Name/ 01 - Track.flac 02 - Track2.flac and so on..
So, because of the folder hierarchy I guess I need a recursive sync. I need the entire Music folder from drive2 to be copied to drive1. I think I can use something like this: rsync -av drive2/Music/ drive1/Music/
However, there are situations when I modify the metadata of certain songs. Those metadata modifications are small like changing the title of the album, and those modification don't necessarily change the size of the FLAC files, but their md5 fingerprint definitely changes because of altering the metadata. Right? I noticed that when I use rsync -a, the rsync utility notices the metadata changes of FLAC files on drive2 and updates the files on drive1 as well to be in sync. Only the changed files gets transferred, which is exactly the behaviour I want. It seems to me that the -a (archive) flag implies the -u which tells to only update changed files. However, I'm curious when rsync transfers the files that got their metadata updated, does the old files get overwritten completely on drive1? I mean they are replaced completely? Are the old files removed before the new ones are copied?  |

(I get the same results with other options I added, eg. sort -k 1,2 -ifm.) It does what I expected for ancient-american, but not for the others. What's going on, and is there another fast and efficient way of doing this without resorting to a full sort (sort works without the -m here).  |
| Alternative to sed -i that does not write temporary files Posted: 30 Aug 2021 09:10 AM PDT I have several scripts that edit template text files, by removing a "tag" and replacing it with e.g. a number. To do this I use the sed -i
command. However, I have an issue with write/read times on the server where I execute the scripts, making the scripts take a long time to run, since the sed -i command writes a temporary file to disk for every execution. Is there an alternative approach that I could use, where a temporary file is not written to disk for every single replacement? Can the text file be edited in the memory and only written once all the replacements have been executed, or could I stack several replacements into the same sed command? To clarify, the script is of the following form: input=shiftLeft.txt while IFS= read -r line do sed -i "s/install, element = $line, at=/install, element = $line, at= -0.001 +/g" processedFiles/layoutDB.seq done < "$input"
That is, I read values from one text file, and then I do some changes in another text file depending on these values. This is done repeatedly for a large number of values.  |
| Unable to mount cloned compact flash after using dd to clone bootable compact flash Posted: 30 Aug 2021 08:42 AM PDT I'm trying to clone a bootable 1GB compactflash to a second 1GB complactflash, but when I try to mount it, i get an error like so, sudo mount /dev/sdb1 /media/frank/cloned/ frank@ThinkPad2:~$ sudo mount /dev/sdb1 /media/frank/cloned/ mount: /media/frank/cloned: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error.
I'm using a single USB CF drive and swapping the original and target CF. It seems to be copying everything, even down to the UUID (not sure if this is bad), but I'm unable to mount the cloned CF, or explore it. Below are the steps I'm taking. The CF I'm cloning is ext3. When I stick the card in the drive it mounts automatically and shows up as **/dev/sdb1 mounted in /media/frank/c44c8412-bf87-4fa4-a6fa-8259aa78bd24 ** I formatted the target CF with the command mkfs.ext3 /dev/sdb1 Then copied form the original CF using dd if=dev/sdb1 of=/home/frank/CFdisk.image To check that the image was good: mount -o loop CFdisk.image /media/frank/compactflash Then.. ls /media/frank/compactflash frank@ThinkPad2:~$ ls /media/frank/compactflash/ bin etc lib mnt proc sbin sys var boot fifos lost+found opt root share tmp vmcores dev home media overlay run srv usr www
So it looks like the CFdisk.image file has been copied correctly. Then putting the target CF in the drive, running lsblk i get see it is at /dev/sdb1 The use dd if=CFdisk.image /dev/sdb1 Afterwards it doesn't automaticly mount. And if I try to mount it manually to a directory, sudo mount /dev/sdb1 /media/frank/cloned/ then I get the error.... frank@ThinkPad2:~$ sudo mount /dev/sdb1 /media/frank/cloned/ mount: /media/frank/cloned: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error.
The command lsblk -f shows that it on the system the cloned CF is... sdb └─sdb1 ext3 c44c8412-bf87-4fa4-a6fa-8259aa78bd24
On the original CF lsblk -f shows sdb └─sdb1 ext3 c44c8412-bf87-4fa4-a6fa-8259aa78bd24 311.2M 60% /media/frank/c44c8412-bf87-4fa4-a6fa-8259aa78b
So, what am I not doing correctly?  |
| Noninteractively identify processes using up a lot of CPU-time Posted: 30 Aug 2021 10:13 AM PDT I have a weird issue: sometimes (always?) when my monitor is turned off, the fans are running loud, even when there shouldn't be much usage of the CPU on the system as far as I know. But as soon as I move my mouse and start top to try to diagnose this, the activity, whatever it is, stops; with the fans winding down. So I want a script/program/method that I could start at some point in time, leave the computer unattended while this program is recording CPU activity of processes, then when I resume operating the computer I should be able to read the program's report from which I would quickly know what processes are making the fans work hard.  |
| How to I properly set the advanced FZF_DEFAULT_COMMAND environment variable to get it working properly with ohmyz.sh with fzf plugin installed? Posted: 30 Aug 2021 08:42 AM PDT I'm new to z shell and ohmyz.sh. I have the following in my zshrc to integrate fzf with rg. This is exactly how it appears in the fzf readme: FZF_BASE=/usr/local/bin DISABLE_FZF_AUTO_COMPLETION="true" DISABLE_FZF_KEY_BINDINGS="true" INITIAL_QUERY="" RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case " FZF_DEFAULT_COMMAND="$RG_PREFIX '$INITIAL_QUERY'" \ fzf --bind "change:reload:$RG_PREFIX {q} || true" \ --ansi --disabled --query "$INITIAL_QUERY" \ --height=50% --layout=reverse
It kind of works but I'm seeing some weird and broken behavior: The weird behavior is that when I reload zshell, fzf fires up immediately without me hitting a key or typing in the command. It works perfectly, otherwise, though. The broken behavior is that when I manually type in fzf, the search is initiated but FZF_DEFAULT_COMMAND is set to what the plugin uses. I tried fixing this behavior by slapping export in front of FZF_DEFAULT_COMMAND but then when I reload zsh, I get an error: /Users/me/.zshrc:export:313: not valid in this context: --bind
Next I turned the ohmyzsh plugin off and modified my code to this: FZF_DEFAULT_COMMAND="$RG_PREFIX '$INITIAL_QUERY'" \ fzf --bind "change:reload:$RG_PREFIX {q} || true" \ --ansi --disabled --query "$INITIAL_QUERY" \ --height=50% --layout=reverse export FZF_DEFAULT_COMMAND
This kind of works, but again, it fires up fzf as soon as I load zsh. And the formatting of the search is mangled and ugly with ansi characters.  |

| Execute a script on ethernet connection/disconnection with systemd Posted: 30 Aug 2021 09:03 AM PDT I have an embedded device that will connect with systemd-networkd to a DHCP server if connected to the local network and will fall back to being a DHCP server if not. I didn't implement it yet but plan using the answer described here https://unix.stackexchange.com/a/309046/114497 . This answer points to use a script that will be started on boot. I was wondering what if the user unplugs the network cable and connects it to a PC at runtime, he'd need to restart the board for the script to start. So the question is: is there a way to start a script when there's an interface change with systemd? PS: I tried using networkd-dispatcher without success. I tried restarting the systemd-networkd service, unplug the ethernet cable but the script I wrote located in /usr/lib/networkd-dispatcher is not executed.  |

indeed typing "locale" I get: # locale locale: Cannot set LC_CTYPE to default locale: No such file or directory locale: Cannot set LC_ALL to default locale: No such file or directory LANG=en_US.utf8 LC_CTYPE=UTF-8 LC_NUMERIC="en_US.utf8" LC_TIME="en_US.utf8" LC_COLLATE="en_US.utf8" LC_MONETARY="en_US.utf8" LC_MESSAGES="en_US.utf8" LC_PAPER="en_US.utf8" LC_NAME="en_US.utf8" LC_ADDRESS="en_US.utf8" LC_TELEPHONE="en_US.utf8" LC_MEASUREMENT="en_US.utf8" LC_IDENTIFICATION="en_US.utf8" LC_ALL=
Set up is: # cat /etc/locale.conf LANG="en_US.utf8" [root@moria ~]# localectl list-locales | grep en_US en_US en_US.iso88591 en_US.iso885915 en_US.utf8
So nothing fancy, it's a fresh out of the box updated CentOS. Trying to set it I get : # localectl set-locale LC_TYPE=en_US.utf8 Failed to issue method call: Invalid Locale data.
So my question: What am I missing? How to set this up correctly. Many thanks!  |
| mv: add number to file name if the target exists Posted: 30 Aug 2021 08:13 AM PDT I'm moving a file to a different folder and would like to add some kind of index to the newly moved file if a file with the same name exists already (the old one should remain untouched). For example, if file.pdf existed I would prefer something like file1.pdf or file_1.pdf for the next file with the same name. Here I've found a variant for the opposite idea — but I don't want to make a "backup". Does mv have some parameters out of the box for that scenario? I use Ubuntu Linux.  |
| Socat exec script in tunnel Posted: 30 Aug 2021 09:51 AM PDT I am running a tunnel like this: socat TCP-LISTEN:9090,fork TCP:192.168.1.3:9090
I would like to run a script to execute code with the strings passing through the tunnel. The script does not change the strings, only processes strings independently but allows passage without changing between both ends. Is this possible?  |
| What is the difference between find . and find . -print Posted: 30 Aug 2021 08:49 AM PDT What is the difference between: find .
and find . -print
What does -print actually do? $ find . . ./hello.txt ./hello ./hello/txt ./hello/hello2 ./hello/hello2/hello3 ./hello/hello2/hello3/txt ./hello/hello2/txt $ find . -print . ./hello.txt ./hello ./hello/txt ./hello/hello2 ./hello/hello2/hello3 ./hello/hello2/hello3/txt ./hello/hello2/txt

| How to share Windows clipboard with Linux using TightVNC? Posted: 30 Aug 2021 09:25 AM PDT I'm connecting to my Debian squeeze server through the Windows TightVNC viewer and tightvncserver on Linux. I have put the following line in my ~/.vnc/xstartup file: autocutsel -fork
However, this only seems to allow 1-way clipboard synchronization; the remote Linux content can be copied to the Windows clipboard, but not the other way around. Is there some way I can copy Windows clipboard content and paste it in Linux through TightVNC?  |
