Ok Corinna, thanks for return, but I don´t understand how can I call these methods. Is there a bash functions?
bruno.galindro@SUNTECHDHFG1 ~ $ seteuid bash: seteuid: command not found As I understand, these are C / C++ methods available when I include these two libraries on my code header: #include <windows.h> #include <sys/cygwin.h> If I try to use the first method (with password authentication): In the page http://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-setuid-overview, right bellow the following text, there are a C source code explaining how to use the setegid and seteuid methods. ##### Back to this logon with password, how can this be used to implement set(e)uid? $$$ Well, it requires modification of the calling application. $$$ Two Cygwin functions have been introduced to support porting setuid applications which only require login with passwords. You only give Cygwin the right access token and then you can call seteuid or setuid as usual in POSIX applications. Porting such a setuid application is illustrated by a short example: ##### Any man page of setuid are pointed to a page that says: #### Standard C Library (libc, -lc) ##### I´dont know how to call these methods using the Cygwin.dll as you explained before... ******************************************************************** ******************************************************************** I´m need to execute the NTBackup application by running it from a ssh connection. Whenever I run it, the backup process can´t be started because the NTBackup application depends the Volume Shadow Copy is working properly. Every time that I start a new backup, the below error is displayed on the event viewer: **** Volume Shadow Copy Service error: An internal inconsistency was detected in trying to contact shadow copy service writers. Please check to see that the Event Service and Volume Shadow Copy Service are operating properly. ***** 2011/3/22 Corinna Vinschen: > On Mar 21 17:56, Bruno Galindro da Costa wrote: >> Corinna, >> >> I´m need to build a small C++ program to exec the "vssadmin list >> writers" with another user context at the remote host? > > Huh?
