No information is available for this page.Learn why. Safe mode is a troubleshooting option for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run.
Note that safe mode is largely useless. Most ISPs that offer Perl also offer other scripting languages (mostly Perl), and these other languages don't have the equivalent of PHP. In other words, if PHP's safe mode won't allow vandals into your web presence, they will simply use Perl. Also, safe mode prevents scripts from creating and using directories (because they will be owned by the WWW server, not by the user who uploaded the PHP script).
So it's not only useless, it's also a hindrance. The only realistic option is to bugger the Apache folks until they run all scripts as the user who's responsible for a given virtualhost or directory. Zebz: The user would not be able to create a directory outside the namespace where he/she would be able to modify its contents. One can't create a directory that becomes apache-owned unless one owns the parent directory. Another security risk: since files created by apache are owned by apache, a user could call the fputs function and output PHP code to a newly-created file with a.php extension, thus creating an apache-owned PHP script on the server. Executing that apache-owned script would allow the script to work with files in the apache user's namespace, such as logs.
A solution would be to force PHP-created files to be owned by the same owner/group as the script that created them. Using openbasedir would be a likely workaround to prevent ascension into uncontrolled areas. Many filesystem-related functions are not appropriately restricted when Safe Mode is activated on an NT server it seems. I would assume that this is due to the filesystem not making use of UID. In all of my scripts, no matter WHO owns the script (file Ownership-wise) or WHO owns the directory/file in question; both UIDs display (getmyuid and fileowner) as UID = 0 This has the rather nasty side effect of Safe Mode allowing multiple filesystem operations because it believes the script owner and file/dir owner are one and the same. While this can be worked around by the judicious application of proper filesystem privileges, it's still a 'dud' that many of Safe Mode's securities are simply not there with an NT implementation. When in safe mode, mkdir creates folders with apache's UID, though the files you create in them are of your script's UID (usually the same as your FTP uid).

What this means is that if you create a folder, you won't be able to remove it, nor to remove any of the files you've created in it (because those operations require the UID to be the same). Ideally mkdir should create the folder with the script's UID, but this has already been discussed and will not be fixed in the near future. And my solution to fix this problem is: 1. You need append the apache group to your script's UID. Turn on safemodegid in the php.ini 3. Chgrp the script to apache, but don't change the UID 4. Now you can use safemode and mkdir now.

Beware that when in safe mode, mkdir creates folders with apache's UID, though the files you create in them are of your script's UID (usually the same as your FTP uid). What this means is that if you create a folder, you won't be able to remove it, nor to remove any of the files you've created in it (because those operations require the UID to be the same). Ideally mkdir should create the folder with the script's UID, but this has already been discussed and will not be fixed in the near future. In the meantime, I would advice NOT to user mkdir in safe mode, as you may end up with folders you can't remove/use.
One of the most common steps when troubleshooting a PC is to boot into Safe Mode. For a long time this has been achieved by pressing the F8 key, this all changes with Windows 10 and its Automatic Repair mode. But what if we want Safe Mode? If you mash the F8 key at just the right time (or get lucky spamming the key during boot up), Windows might still take you to a screen that lets you get into the recovery environment. From there, you can boot into Safe Mode (and we’ll talk about that environment a bit later. The trouble is that some computer manufacturers disable this option.
And even on PCs that still support it, Windows startup (and particularly the handoff between the regular boot process and Windows startup) happens so much faster now, you barely have time to press the key. The good news is that getting into Safe Mode is doable. The process is just more hidden now. RELATED: Note: This article is written using screenshots from Windows 10, but the techniques work pretty much the same way in Windows 8. We’ll note any differences where they occur.
Step One: Get to the Advanced Troubleshooting Tools in the Recovery Environment Most of the ways you access Safe Mode involve getting into the Windows recovery environment first. The recovery environment includes a number of troubleshooting options, and Safe Mode is one of them. How you get there depends on whether your PC can start Windows normally or not.
If Your PC Can Start Windows Normally If your PC can successfully get to the Windows login screen when you start it up (or you can actually sign into Windows), the easiest way to get to the recovery environment is to hold down the Shift key while clicking Restart (either right on the sign in screen or from the Start menu). You can also get to the recovery environment through your Settings app.
Press Windows+I to open Settings, and then click the “Update & Security” option. In the left pane, switch to the “Recovery” tab. In the right pane, scroll down a bit, and then click the “Restart Now” button in the “Advanced Startup” section. Using either of these methods (Shift+Restart or the Settings app) takes you to the recovery environment, which we’ll discuss just a bit later in our section on the second step of this process.
If Your PC Cannot Start Windows Normally If your PC won’t start Windows normally twice in a row, it should automatically present you with a “Recovery” option that lets you see advanced repair options. Note: We’re talking here specifically about if your PC is able to power on and successfully run through its hardware initialization, but then cannot load Windows successfully. If your PC is having trouble even getting to the stage where Windows loads, check out our guide on for more help. RELATED: If your PC does not present you with this screen, you can try starting your PC from a.
It’s best if you’ve made one ahead of time, but in a pinch, you can create one from another PC running the same version of Windows. It’s also possible that you can mash the F8 key during boot (but before Windows starts trying to load) to access these screens. Some PC manufacturers disable this action, and on some PCs, startup is fast enough that it’s hard to hit the key at the right time. But, there’s no harm in trying. Whichever way you get into the recovery environment, you’ll have access to the advanced troubleshooting tools intended for helping you recover a PC that won’t start normally. Safe Mode is included in those tools.
Step Two: Use the Advanced Troubleshooting Tools to Start Safe Mode When you get to the advanced troubleshooting tools (whether that’s by using the Shift+Restart trick, mashing the F8 key, or using a recovery drive), you’ll arrive at a screen that lets you access the troubleshooting tools. Click the “Troubleshoot” button to proceed. On the “Troubleshoot” screen, click the “Advanced Options” button. On the “Advanced Options” page, click the Startup Settings” option.
In Windows 8, this option is labelled “Windows Startup Settings” instead. And finally, now that you see what we meant by “hidden,” hit the “Restart” button. You’ll see a version of the familiar Advanced Boot Options menu. Press the number corresponding to the startup option you want to use (i.e., press the 4 key for regular Safe Mode). Note that if you’re using Windows 8, your PC will restart first, and then you’ll actually see the same “Advanced Boot Options” screen you’re used to from older versions of Windows. Use the arrow keys to select the appropriate Safe Mode option, and then hit Enter to boot into Safe mode.
Yes, it’s a convoluted way to get to Safe Mode, and these options are much more hidden than they were in the past. But, at least they’re still available. Alternative Option: Force Windows to Start in Safe Mode Until You Tell It Not To Sometimes, you’ll be troubleshooting something that requires you to boot into Safe Mode several times. Going through the whole procedure we’ve just outlined gets to be a real pain if you have to do it each time you restart your PC. Fortunately, there’s a better way. The System Configuration tool built into Windows gives you the ability to enable a “safe boot” option.
This essentially forces Windows to boot into Safe Mode every time you restart your PC. To start Windows normally again, you have to go back into the System Configuration tool and disable the option. You can even choose the type of Safe Mode into which you want Windows to start:.
Minimal: normal Safe Mode. Alternate shell: Safe Mode using only the Command Prompt. Active Directory repair: Used only for repairing an Active Directory server. Network: Safe Mode with networking support RELATED: This alternative method provides a great way to boot into Safe Mode repeatedly when you need to, but you might also find it quicker than booting into Safe Mode using one of the more conventional methods we’ve discussed—even if you only need to visit Safe Mode once.
