Top Forums UNIX for Advanced & Expert Users CentOS7 restoring file capabilities Post 303025724 by rbatte1 on Saturday 10th of November 2018 12:42:02 PM

Yes, we'd tried that without success. I hadn't considered the other file attributes options though. Sadly, it seems no better. A simple test just on CentOS7 gives me this:-
Code:
# tar -cvpzf - --xattrs --acl --selinux /usr/bin/ping | (cd /tmp;tar -xzvp --xattrs --acl --selinux  -f -)
tar: Removing leading `/' from member names
/usr/bin/ping
usr/bin/ping
# getcap -v /usr/bin/ping /tmp/usr/bin/ping
/usr/bin/ping = cap_net_admin,cap_net_raw+p
/tmp/usr/bin/ping

Am I doing something daft? At worst I've scanned all local files and collected the capabilities into a file that then is part of the tarball. On recovery I can apply them within my kickstart file. It's just more steps to wory about.

I have found that simply copying a file loses the capabilities, one has to cp --preserve=xattr source target Maybe I don't understand where these are stored. Maybe I don't need to know, just understand the rules I need to follow Smilie

I know I can achieve it with rsync but I can't neatly use that when doing a PXE recovery and I'd have to get the files out to all the remote locations individually too, which would be a nightmare.

I will keep digging. Any other suggestions to explore very welcome.



Kind regards,
Robin

getusershell(3C)					   Standard C Library Functions 					  getusershell(3C)

NAME
getusershell, setusershell, endusershell - get legal user shells SYNOPSIS
#include <unistd.h> char *getusershell(void); void setusershell(void); void endusershell(void); DESCRIPTION
The getusershell() function returns a pointer to a legal user shell as defined by the system manager in the file /etc/shells. If /etc/shells does not exist, the following locations of the standard system shells are used in its place: /bin/bash /bin/csh /bin/jsh /bin/ksh /bin/pfcsh /bin/pfksh /bin/pfsh /bin/sh /bin/tcsh /bin/zsh /sbin/jsh /sbin/pfsh /sbin/sh /usr/bin/bash /usr/bin/csh /usr/bin/jsh /usr/bin/ksh /usr/bin/pfcsh /usr/bin/pfksh /usr/bin/pfsh /usr/bin/sh /usr/bin/tcsh /usr/bin/zsh /usr/xpg4/bin/sh The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells. The setusershell() function rewinds the file or the list. The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells. RETURN VALUES
The getusershell() function returns a null pointer on EOF. BUGS
All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved. SunOS 5.10 30 Aug 2004 getusershell(3C)
