I'm having problems with files created from within Eclipse running on Linux.
All files (as far as I know) only gets the owner read and write permissions. Build output is the same but with the execute permission added.
The "test" file is created in Eclipse by File > New, and the "test1" file is created in command line by "touch" by the same user in the same folder.
-rw-------. 1 user stdgroup 0 Mar 15 10:22 test
-rw-r--r--. 1 user stdgroup 0 Mar 15 10:23 test1
My umask is set to 0022, so the output from the "touched" file is correct.
I'm running Eclipse Oxygen.2 Release 4.7.2 on Linux RedHatEnterpriseServer 7.3.
Anyone knows if there is a setting in Eclipse that can cause this, or any other ideas as to why this happens?

We had some 12 agents (vsts-agent-linux-x64-2.188.4) running on one Az VM (Ubuntu 20.04.2 LTS) as processes (./config.sh && screen ./run.sh). All was well..
I had to run some command related to /tmp folder but it kept showing busy and we suspected that our Agents might be using /tmp. Unfortunately instead of any other clean way of stopping the agents, we killed all processes on this VM manually, including the agents'.
After the /tmp related command ran successfully, I tried running screen ./run.sh from one of the agent directories. And I got an error:
Failed to create CoreCLR, HRESULT: 0x80004005
I also had tried :
.agent2/run.sh and I got the error :
ldd: ./bin/libcoreclr.so: No such file or directory
ldd: ./bin/System.Security.Cryptography.Native.OpenSsl.so: No such file or directory
ldd: ./bin/System.IO.Compression.Native.so: No such file or directory
ldd: ./bin/System.Net.Http.Native.so: No such file or directory
Failed to create CoreCLR, HRESULT: 0x80004005
I even downloaded a new .tar for the agent and ran a fresh ./config . But I get the same error on ./config as well
Is there a solution to this? Please help
export COMPlus_EnableDiagnostics = 0, and then running ./config from the agent directory. worked!
I had this issue when running as the non-privileged user specified in the systemd file but running as root user worked fine.
Finally used:
strace -f -o trace.log /<executable path>/<executable name>
Which led me to:
9183 mknod("/tmp/clr-debug-pipe-9183-8112345738-in", S_IFIFO|0700) = -1 EACCES (Permission denied)
This caused me to compare the /tmp directory between working and non-working boxes.
[<not-working-hostname>]$ ll /
drwxrwxr-x 7 root root 93 Jan 5 21:37 tmp
[<working-hostname>]$ ll /
drwxrwxrwt 7 root root 93 Jan 5 21:59 tmp
(Note the r-x vs rwt)
Fix:
[<hostname>]# chmod 1777 /tmp
For anyone else reading this; it seems the issue was caused by permissions and suexec was part of the issue. Having disabled suexec, all is well again (subject to consequential issues I may find later).
Two files I have in (say) dir1, in /cgi-bin/dashboard-login/ and they use CGI::Session to manage the session.
Both files set a new session like this:
my $session = new CGI::Session(undef, $cgi, {Directory=>"$sessions_dir_location"}) or die CGI::Session->errstr;
This means the second file is actually opening the session created by file1. All good so far.
File 3 is in the same sub-domain but in a different dir (/cgi-bin/dashboard/). It also runs that session string but I get the following error:
Software error:
new(): failed: load(): couldn't retrieve data: retrieve(): couldn't open '/var/www/vhosts/example.com/sessions_storage/cgisess_fc6c62eee135f6cd418defef4516a59c': Permission denied at index line 38.
For help, please send mail to the webmaster (root#localhost), giving this error message and the time and date of the error.
In Filezilla, I see that the file permission is set to "dfr (0640)" for the latest session file but, the previous one has the permissions "adfr (0640)" That adfr file can be opened in filezilla and didn't have any issues when I ran my scripts. Now the session files are being created as "dfr (0640)". IS there a way to set the server (or the CGI::Session), to apply "adfr (0640) permissions?
And, in your experience, is that the likely cause of the problem?

For anyone else reading this, it was a permissions issue. It seems to relate to SuExec. Having disabled SuExec, temporarily, until I learn more about directory locations and permissions fully, all is well again.
I'm adding binaries to a release in github by dragging and dropping them into the binaries upload section when creating a new release. The binaries have the following permissions on my local (OSX):
-rwxr-xr-x 1 user group 100 Mar 22 00:00 file1
-rwxr-xr-x 1 user group 100 Mar 22 00:00 file2
-rwxr-xr-x 1 user group 100 Mar 22 00:00 file3
-rwxr-xr-x 1 user group 100 Mar 22 00:00 file4
However when I download the binary from Releases the file mode has changed:
-rw-r--r--# 1 user group 100 Mar 22 09:00 file1
Has this been documented anywhere? Is there a way to preserve file permissions when uploading binaries to github?
Is there a way to preserve file permissions when uploading binaries to github?
I don't believe so. People that download the file will need to chmod +x to get the execute permission back. A file's permission is not stored within the file itself, rather it is an attribute of the file on the file system.
If you really need to preserve complex permissions for files, I would suggest storing the files in a container that preserve permissions. Like a DMG for macOS, and uploading the DMG instead.
I use putty to log in to a solaris server. while i was performing a copy operation I pressed left arrow key to edit the file name but it kept adding this character ^[[D desperate I pressed return key and the copy operation got complete
cp temp.jar temp.jar^[[D^[[D^[[D^[[D^[[D^[[D^[[D^[[D^[[D
I was planning to rename is as temp.jar.test, I used 'ls' command to check what has happened and to my surprise two files came up with same name!
root[dev1]# ls -lt temp*
-rw-r--r-- 1 root other 488554 Apr 11 02:25 temp.jar
-rw-r--r-- 1 root other 488554 Apr 11 02:22 temp.jar
-rw-r--r-- 1 root other 488554 Apr 11 02:22 temp.jar.041114
-rw-r--r-- 1 root other 488487 Sep 30 2013 temp.jar.032514
and I used 'rm' command to delete, the original file got deleted but the file copied with ^[[D character is not getting deleted. And I'm getting a msg like 'eisvr.jar.: No such file or directory'
Help me delete the file. I tried issuing 'rm temp.jar^[[D^[[D^[[D^[[D^[[D^[[D^[[D^[[D^[[D'. It resulted in more errors.
The simplest way would be to run this command:
rm -i temp.jar?????????*
and answer yes when prompted to remove the bogus one.
I followed some online guides trying to get some headless VMs to start/suspend automatically at boot/shutdown on my Mac. I can't get it to work at all. This is my first time trying to get script runs on Startup/Shutdown, so it could be that I'm just missing something very basic and if that's the case I apologize.
These are the steps I followed:
Created a directory /Library/StartupItems/HeadlessVM
Created two files within that directory:
-rwxr--r-- 1 root wheel 242 Feb 19 19:05 HeadlessVM
-rw-r--r-- 1 root wheel 188 Feb 20 12:42 StartupParameters.plist
Contents for HeadlessVM
$ cat HeadlessVM
#!/bin/sh
. /etc/rc.common
StartService ()
{
ConsoleMessage "Starting HeadlessVM"
/usr/local/bin/runvmheadless
}
StopService ()
{
ConsoleMessage "Suspending HeadlessVM"
/usr/local/bin/suspendvmheadless
}
RunService "$1"
Contents for StartupParameters.plist
$ cat StartupParameters.plist
{
Description = "Runs/Suspends Virtual Machine Headless on OS X Startup/Shutdown";
Provides = ("HeadlessVM");
Uses = ("Disks");
OrderPreference = ("Late");
}
Created my script files, that will perform both actions:
-rwxr-xr-x# 1 xxxxxxx admin 164 Feb 19 01:06 runvmheadless
-rwxr-xr-x# 1 xxxxxxx admin 160 Feb 19 01:19 suspendvmheadless
Contents for runvmheadless
$ cat runvmheadless
#!/bin/bash
"/Applications/VMware Fusion.app/Contents/Library/vmrun" -T fusion start "/Volumes/Archive/Virtual Machines/vm.vmwarevm/vm.vmx" nogui
Contents for suspendvmheadless
$ cat suspendvmheadless
#!/bin/bash
"/Applications/VMware Fusion.app/Contents/Library/vmrun" -T fusion suspend "/Volumes/StaticData/Virtual Machines/vm.vmwarevm/vm.vmx"
My troubleshooting so far:
If I run the scripts from the terminal, they work as intended.
If I run sudo /sbin/SystemStarter (start or stop) "HeadlessVM" it also works.
On console I only see the following when I reboot, no clue on what's wrong tho.
2/20/12 12:11:09.128 PM SystemStarter: Runs/Suspends Virtual Machine Headless on OS X Startup/Shutdown (100) did not complete successfully
Appreciate any help, Thank you.
I found what was wrong. The code above is fine, the problem is that my scripts are trying to get data from an encrypted secondary disk which was not available at boot time.
I used this in order to bypass this problem:https://github.com/jridgewell/Unlock
