Here is a Common problems and solutions page. Key does not exist. You can try this program if you are using Windows 7 or 8. (I personally have not tried it). The previous examples do not set the default value for the newly created registry key. If the registry key already exists (as it does in this specific case), use the Set-Item cmdlet to assign a default value to the registry key as follows.
DOSBox v0.74-2 Manual (always use the latest version from ) DOSBox v0.74-2 Manual NOTE: While we are hoping that one day DOSBox will run all programs ever made for the PC, we are not there yet. At present, DOSBox running on a high-end machine will roughly be the equivalent of a Pentium I PC. DOSBox can be configured to run a wide range of DOS games, from CGA/Tandy/PCjr classics up to games from the Quake era. INDEX:. 1. Quickstart: Type INTRO in DOSBox for a quick tour.
It is essential that you get familiar with the idea of mounting, DOSBox does not automatically make any drive (or a part of it) accessible to the emulation. See the FAQ entry 'How to start?' As well as the description of the MOUNT command (section 4: 'Internal Programs'). If you have your game on a cdrom you may try this guide: 2. Start (FAQ): : How to start?: Do I always have to type these 'mount' commands?: How do I change to fullscreen?: My fullscreen is too large.: My CD-ROM doesn't work.: The game/application can't find its CD-ROM.: The mouse doesn't work.: There is no sound.: What sound hardware does DOSBox presently emulate?: The sound stutters or sounds stretched/weird.: I can't type or: in DOSBox.: Right Shift and ' ' doesn't work in DOSBox. (Windows only): The keyboard lags.: The character/cursor/mouse pointer always moves into one direction!: The game/application runs much too slow/too fast!: The game/application does not run at all/crashes!: DOSBox crashes on startup!: My Build game(Duke3D/Blood/Shadow Warrior) has problems.: Can DOSBox harm my computer?: I would like to change DOSBox's options.: Great Manual, but I still don't get it. START: How to start?
At the beginning you've got a Z: instead of a C: at the prompt. You have to make your directories available as drives in DOSBox by using the 'mount' command. For example, in Windows 'mount C D: GAMES' will give you a C drive in DOSBox which points to your Windows D: GAMES directory (that was created before). In Linux, 'mount c /home/username' will give you a C drive in DOSBox which points to /home/username in Linux. To change to the drive mounted like above, type 'C:'. If everything went fine, DOSBox will display the prompt 'C: '. AUTOMATION: Do I always have to type these commands?
In the DOSBox configuration file is an autoexec section. The commands present there are run when DOSBox starts, so you can use this section for the mounting. Look at Section 13: The configuration (options) file FULLSCREEN: How do I change to fullscreen? Press alt-enter. Alternatively: Edit the configuration file of DOSBox and change the option fullscreen=false to fullscreen=true. If fullscreen looks wrong in your opinion: Play with the options: fullresolution, output and aspect in the configuration file of DOSBox. To get back from fullscreen mode: Press alt-enter again.
FULLSCREEN: My fullscreen is too large. This is can be a problem on Windows 10, if you have display scaling set to a value above 100%. Windows in that case will resize the screen on top of dosbox resizing the screen, which can happen for the output: ddraw, opengl, openglnb, overlay. You can disable this Windows behaviour by enabling a specific compatibility setting: - Right-click the DOSBox icon and select 'Properties'. Go to the 'Compatibility' tab.
Click on 'Change high DPI settings'. Tick 'Override high DPI scaling behaviour' and set it to 'Application'. Apply the changes by clicking on 'OK'. Unfortunately, this compatibility option causes some side effects in windowed mode, and in this case you will need to change the resolution in the config/Options file for windowresolution (e.g.
Alternatively, you can disable the display scaling and or use a lower fullresolution value. CD-ROM: My CD-ROM doesn't work. To mount your CD-ROM in DOSBox you have to specify some additional options when mounting the CD-ROM.
Ssh has the -i option to tell which private key file to use when authenticating: -i identityfile Selects a file from which the identity (private key) for RSA or DSA authentication is read. The default is /.ssh/identity for protocol version 1, and /.ssh/idrsa and /.ssh/iddsa for protocol version 2. Identity files may also be specified on a per-host basis in the configuration file. It is possible to have multiple -i options (and multiple identities specified in configuration files).
Is there a similar way to tell git which private key file to use on a system with multiple private keys in the /.ssh directory? Environment variable GITSSHCOMMAND: From Git version 2.3.0, you can use the environment variable GITSSHCOMMAND like this: GITSSHCOMMAND='ssh -i /.ssh/idrsaexample' git clone example Note that -i can sometimes be overridden by your config file, in which case, you should give SSH an empty config file, like this: GITSSHCOMMAND='ssh -i /.ssh/idrsaexample -F /dev/null' git clone example Configuration core.sshCommand: From Git version 2.10.0, you can configure this per repo or globally, so you don't have to set the environment variable any more! Git config core.sshCommand 'ssh -i /.ssh/idrsaexample -F /dev/null' git pull git push. There is no direct way to tell git which private key to use, because it relies on ssh for repository authentication. However, there are still a few ways to achieve your goal: Option 1: ssh-agent You can use ssh-agent to temporarily authorize your private key. For example: $ ssh-agent sh -c 'ssh-add /.ssh/idrsa; git fetch user@host' Option 2: GITSSHCOMMAND Pass the ssh arguments by using the GITSSHCOMMAND environment variable (Git 2.3.0+).
For example: $ GITSSHCOMMAND='ssh -i /.ssh/idrsa -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no' git clone user@host You can type this all on one line — ignore $ and leave out the. Option 3: GITSSH Pass the ssh arguments by using the GITSSH environment variable to specify alternate ssh binary. For example: $ echo 'ssh -i /.ssh/idrsa -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no $.' ssh $ chmod +x ssh $ GITTRACE=1 GITSSH='./ssh' git clone user@host Note: The above lines are shell (terminal) command lines which you should paste into your terminal. They will create a file named ssh, make it executable, and (indirectly) execute it. Note: (2005). Option 4: /.ssh/config Use the /.ssh/config file as suggested in other answers in order to specify the location of your private key, e.g.
Host github.com User git Hostname github.com IdentityFile /.ssh/idrsa. If you encounter the following error fatal: transport 'ext' not allowed, you have to whitelist the ext protocol via the export GITALLOWPROTOCOL=ext.
Basically, the git-remote-ext remote helper (which supports 'ext::ssh example.com%S foo/repo' URLs) allows arbitrary command execution. This normally isn't ever a concern because user always sees and trusts the URL they pass to git. However git submodules, through the.gitmodules file, allow an attacker to request the client to fetch arbitrary git URLs.
– May 13 '18 at 17:21. After my struggle with $GITSSH I would like to share what worked for me. Through my examples I will assume you have your private key located at /home/user/.ssh/jenkins Error to avoid: GITSSH value includes options $ export GITSSH='ssh -i /home/user/.ssh/jenkins' or whatever similar will fails, as git will try to execute the value as a file. For that reason, you have to create a script.
Working example of $GITSSH script /home/user/gssh.sh The script will be invoked as follows: $ $GITSSH username@host -p Sample script working could look like: #!/bin/sh ssh -i /home/user/.ssh/jenkins $. Note the $. at the end, it is important part of it. Even safer alternative, which would prevent any possible conflict with anything in your default config file (plus explicitly mentioning the port to use) would be: #!/bin/sh ssh -i /home/user/.ssh/jenkins -F /dev/null -p 22 $. Assuming the script is in /home/user/gssh.sh, you shall then: $ export GITSSH=/home/user/gssh.sh and all shall work.
