Anne: This is something that worked fine, for several years. It was my box, before my daughter got it, and I used the DVD drive, without problems. That it works OK in MS Windows XP and that I can boot the box from the same DVD, without problems, has me leaning more toward a problem with CentOS 5 Mounting the DVD, in that box. If it is a HW problem, I would think the problem would also appear in Windows and when I boot from that DVD. However, that it works OK, in 2 other Desktops, would possibly indicate a HW problem in that box.

The entry in fstab will mount automatically unless noauto is specified. With HAL, UDEV et al active on your system, it is safe to assume that one of them is "mounting" the device. At the time X starts, devices that are handled via this facility will be made available to the user of the desktop (and "ownership" is assigned to that user too IIUC). I don't recall seeing noauto in your fstab entry. Before logging on via X, switch to a vt and type mount. You'll probably see the device already mounted. Then after you log in via X, do "mount" again. I expect you'll see two mounts on the device. > > The problem is that I still have two icons on the desktop for a single > mounted disk. AFAIK, that is not a problem except to the "wetware". The system is perfectly happy with it. See "man mount" and look for "bind" to see evidence of this. I'm not that knowledgeable about the desktop, but I think Gnome has some stuff it starts up that comminucates with HAL or udev to locate removable devices and make them available on the desktop. This goes beyond mount, IIUC. Witness a CD or DVD that is a video or music media. It has no file system, as we understand it, and can't be formally mounted. I *think* that's correct. Those devices should get accessed through the raw device interfaces. Maybe Gnome has some preferences about this? > HTH -- Bill ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Nothing requires it. Same for cups. So, why did it get installed? I would guess that sendmail is included in @core or something else is that depends on a mail package. Just because you include postfix later, you can't count on things included in @core that depend on a mail program to know that postfix will eventually be there. I believe sendmail is the default mail package when it comes to resolving dependencies, unless postfix is already installed. I have a work-in-progress kickstart config that attempts a more minimal install than can be done from CD. The key is "--nobase". But then many essential things must be explicitly installed.

Nothing requires it. Same for cups. So, why did it get installed? I usually do a rpm -q --provides and have it list the capabilities that the rpm provides and then do a --whatrequires on the capabilities themselves. Hopefully someone more knowledgeable can jump in and explain an easier way. But that is what I do. You'll see that one of the items that sendmail provides is smptdaemon which is the usual source of dependencies in my experience. However postfix also provides it, so perhaps that's no help.

[CentOS] Turning off Gnome and other stuff
Hi. Just did a Centos5.1 on a dual-core 64 bit machine, sweet!!! But would like to turn off the desktop and just about all the programs started when the X server is fired up. The machine will be driving a full scale 737NG cockpit flight simulator and we really don't need anything beyond the X server and an xorg.conf file to setup the two dual-headed graphics cards.

As I am having a problem with deleting files on a client and then can't empty the trash because of permission problems. Will this solve this issue or do I have problems elsewhere? Keep in mind this is a mixed node network with windows and linux. I'm taking pointers from any one with heavy samba experiance. As I am no samba guy. Also pointers on clustering samba with DFS. It gets put in the root of the share that you activate it in. I am not sure if you can make it a global option, but maybe. That's where it gets put. After editing the conf file and putting the option in. I'm not sure of what your issue is, when you say "empty the trash" do you mean deleting files from "Recycle Bin"? Logged in as root on a linux client using share mode can't delete a file or folder when made by root on the samba server in one of the shares. That is using the user nobody. Would that be correct as user nobody only can't delete file made by root n the samba server. I suspect after really thinking about it I'll be much better of adding the linux client to Active Directory and do all authentication that way to solve everything. Then later on setup samba to serve the Windows user profiles. I'm not on AD yet, hoping to put that bullet off for a while. -- MailScanner is like deodorant...

TIME_WAIT states happen when you close a TCP connection which shouldn't happen at all on nailed-up mounts. Do you have the automounter set up for short timeouts and something that could be traversing the mount points frequently to stir up traffic and connections? You could switch to UDP to avoid the TCP state handshakes and overhead. -- Les Mikesell [EMAIL PROTECTED] ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

It is obvious that authentication is failing for user "smbuser", but what to do about it is less obvious. http://catb.org/~esr/faqs/smart-questions.html What have you tried? How have you set up authentication for samba? Have you created a smbpasswd file and is the user in it, or are you expecting to authenticate against another server? Try smbclient -L GIServer and see what it returns. Phil ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
