my Linux laptop started to have a problem of setting my home directory with group write permission
$ ls -ld $HOMEdrwxr-x--- 34 user users 4096 Jan 30 21:45 /home/user
$ ls -ld $HOMEdrwxrwx--- 34 user users 4096 Jan 30 21:45 /home/user
This usually doesn't cause a problem but since recently it started settings group write on servers as well which I did ssh login; and once logout, the next time it doesn't allow re-login from server side sshd audit logs, says because of group write permission is set it doesn't allow my account to login;
this wired problem has started settings multiple ssh servers, either at home Linux server, or Linux server in the cloud,but it isn't always reproducible, in past 30 days it happened 3 times to 4 different servers
I suspect current Linux laptop has a software virus or something because it has been in use for 2 years; I re-installed the laptop with latest Fedora 27 and all started as fresh, but 2 weeks later right now, the group write permission is set again to one of my servers;
I checked all bash_history and system logs, didn't see any explicit bash call of "chmod g+w ..." ; so I suspect some software is calling by chmod syscall, so I wonder anyone knows how to set a system wide chmod audit? and if a whole hard drive anti-virus scan is necessary, which anti-virus scan software do you recommend?
It's weird that nothing worse than a group write permission set. No damage to system, no malfunctioning. The newly installed Linux system just functions perfect if without that.But I am kind of pretty sure it's this laptop, because whenever this laptop is down time, I use another newer laptop I bought a few months ago, nothing bad happens yet during this current 3years old laptop downtime.
I have a problema with curl, in Fedora 26, I imported the certificate into
the /etc/pki/ca-trust/source/anchors/, and after I run the command:
update-ca-trust extract, after that, curl trust on the self-signed
But, in Fedora 27, I do the same configuration, but curl don't trust in the
