How to correctly setup passwd and group to access mounted drives?
Hi, I am trying this route after failing to find a relevant topic on web or with local gurus. Problem in short: = I have a folder on a unix server mapped as a windows drive z(y is another drive from another unix server). I am able to browse through the folders from windows explorer and read/write there. I am running into an issue when I access those mapped network drives from cygwin. When I try I get the following error message [EMAIL PROTECTED] /cygdrive $ ls -l total 4 drwxrwxr-x+ 30 SYSTEM 0 Jun 3 09:35 c drwxr-xr-x 37 uday_p Domain Users 1536 Mar 12 23:34 y drwxr-xr-x 36 uday_p Domain Users 1536 May 31 23:58 z [EMAIL PROTECTED] /cygdrive $ ls y ls: reading directory y: Permission denied [EMAIL PROTECTED] /cygdrive $ ls z ls: reading directory z: Function not implemented [EMAIL PROTECTED] /cygdrive $ [EMAIL PROTECTED] ~ $ mount C:\cygwin\bin on /usr/bin type system (binmode) C:\cygwin\lib on /usr/lib type system (binmode) C:\cygwin on / type system (binmode) c: on /cygdrive/c type system (binmode,noumount) y: on /cygdrive/y type system (binmode,noumount) z: on /cygdrive/z type system (binmode,noumount) [EMAIL PROTECTED] ~ $ My windows domain is MYDOM I did do the mkgroup -l -d MYDOM /etc/group and mkpasswd -u uday_p -p /home -d MYDOM /etc/passwd I am able to navigate the directories though which means that I do not have the group/user id set properly from cygwin. I do not know how to fix that. The id on UNIX server is unix2 /users/udayb id -a uid=1066(uday_p) gid=2(eng) groups=2(eng),15(crypto) and on cygwin it is [EMAIL PROTECTED] /cygdrive $ id -a uid=264583(uday_p) gid=10513(Domain Users) groups=544(Administrators),545(Users), 160957(ArchBaseDataGroup),10513(Domain Users),13521(eng),13522(Engineering),29064(LEX.MFG-SUITE.M) [EMAIL PROTECTED] /cygdrive $ I am a developer on unix environment and I have a project where my code from unix server has to be compiled from windows (intel ixp stuff). Will appreciate any help in getting the access issue fixed. I am guessing that it is because of the difference in the gid between unix and on cygwin. I did manually modify the entry on cygwin to mirror the value in unix, but that did not help.

Here is how I have to setup I have my CVS repository on a unix server that I have to access from cygwin. I map my private branch as a windows mapped drive (from windows explorer Tools-Map Network Drive...). This mapped drive shows up as a new drive (in this case y and z). I am able to browse and read/write into these mapped drives (they do get reflected on unix). However, I am not even able to read those folders through cygwin which is vital because my Intel compiler is usable only through that option. I am able to navigate the directories through cygwin, but read and write fail. Thanks Uday Best regards, Spiro. -- Spiro R.

Re: How to correctly setup passwd and group to access mounted drives?
A nice way to check for being the right user is to use the whoami utility - the windows version out in \windows\system32, not the cygwin one. If it displays that you are sshd_server things are not well. I still do not fully understand the need to do this, but on some recent systems I've installed it was necessary to generate the groups file with the -u flag to place the user names in the groups they belong to. Perhaps that might help (and perhaps someone with more knowledge can comment on the correctness of this suggestion...): mkgroup -l -d -u /etc/group (you can leave off the -d if you're not in a domain) -- Eric - Original Message From: Spiro Trikaliotis [EMAIL PROTECTED] To: cygwin@cygwin.com Sent: Thursday, June 5, 2008 11:46:59 AM Subject: Re: How to correctly setup passwd and group to access mounted drives?
