The directory was chown -R to staff:staff and chmod -R to 770 I'll give a try on 777 on Monday (US Sunday).

I did try the -U previously. samba will ask me for a password, and then show me the standard information. So it's rather odd that this doesn't show up on log, and coming in from the network doesn't work at all.

First, I'll repeat my advice about using the SME server distribution which makes it as easy as filling in simple forms on web pages for users, groups, and shares and basically would take no other administration unless you want email or additional services. But, if you want to do it the hard way, you probably have an authentication issue. With the default security setting of 'user', the windows users must authenticate before they can even see a share - and things get weird if the name they used to log into windows is not the same as the linux/samba login name. You can still map drives if you explicitly specify \\server\share, 'connect as other user' and fill in the name and password, but browsing for shares often doesn't work. If you aren't too concerned about security, you can change this to 'security = share' and then you can browse before authenticating, and also have the option to authenticate as different users when connecting to different shares on the same machine which you can't do in user or server modes. I don't understand the log issue, though. Are you sure smbd is running? Nmbd would be enough to activate the netbios name - maybe you have a syntax error in smb.conf and smbd did not start. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

This could be it as the names they use to log into their Windows machine are not their own. Most of them are inherited PC, they simply continued using the previous login since no password were set, usually.

I have tail -f on both their logs and ls the log folder every time. The startup message gets logged everytime I did a service restart on trying a different setting.

There's a tradeoff here. When you cobble up a one-of-a-kind system yourself, not only is it much more likely to break than one set up by an expert, but no one else is going to be having the same problem so you won't be able to easily get help from a mail list or forum. If SME server breaks, other people will likely have already posted the workaround or update to fix it. > It's kind of like folks who grew up knowing only GUI, they usually are > helpless if the mouse doesn't work. Not exactly. SME server mostly runs the same programs with the same config files as Centos, so you can look at the configs and understand them if you want. The configs are actually created by perl scripts that merge canned snippets with your web form entries, so it is somewhat more difficult to modify them in ways that weren't planned but that's not really out of the question either. >> authentication issue.

Consult the man page for smb.conf for details. The configuration from smb.conf is re-read approximately once a minute so you don't actually have to restart the service for changes once they are saved to take effect. Also, it's useful to note that in 'security = user' mode, that a user must exist in both /etc/passwd and samba s passdb (usually now /etc/samba/passdb.tdb) and you can figure this out by executing something like 'testparm -s -v |grep passdb' If you want detailed help, it's generally helpful to include the output of the 'testparm -s' command. Last thing that I have found useful to test users and passwords in samba are things like this from command line on Linux machine... smbclient -L $NETBIOS_NAME -U% # anonymous authentication should show shares (no password) smbclient -L $NETBIOS_NAME -U administrator # should prompt administrator password and generally, there is a file # called /etc/samba/smbusers which maps 'root' to 'administrator' Once a 'user' like administrator above can connect without error, then you can test access to specific shares like this... smbclient //$NETBIOS_NAME/staff -U administrator # should prompt for administrator password smbclient //$NETBIOS_NAME/staff -U $SOME_USER # should prompt for $SOME_USER password and if user is allowed access, you are given a command prompt.

Thank you! I feel better about not finding the packages for nut, when I searched with yum! :-) I hope apcupsd will work with this UPS, if I can configure it properly. I will try apcupsd again.

[CentOS] trying to install 5.2 on a laptop
Hello. I burned a CD with the 5.2 netinstall iso, and installed it onto a laptop (Acer Aspire 3680). Note that I'm *totally* new to laptops. The install went fine. But, when I boot it, it errors at the user login. A screen comes up, stating that X11 cannot start, and that it's probably the mouse. A bit of investigating revealed that there is no Synaptics module installed. It will boot into runlevel=3. I tried the 'upgrade' option of the netinstall disk; it saw that 5.2 is installed, and quit. |:( The X wiki suggested that I try adding this to /etc/X11/xorg.conf: Section "ServerFlags" Option "AllowMouseOpenFail" "1" EndSection Using "cat xorg.conf", I seeSection "InputDevice" , which refers to the Synaptics module. Being new-ish to linux, I can't figure out the text-based editor (vi) to modify the file. I have "System Rescue CD" and "Ultimate Boot CD", but (apparently) they don't mount the installed system. I have some Fedora install disks (if they'd be of any help) - but not a rescue CD. It seems like CentOS doesn't have a rescue CD - would Fedora's help?

[CentOS] Fail2Ban
Hi all, I am trying to get fail2ban going on my server and its log message reports the following error 2009-02-16 17:42:05,339 ERROR: 'iptables -L INPUT | grep -q fail2ban-SSH' returned 256 2009-02-16 17:42:05,354 ERROR: 'iptables -D INPUT -p tcp --dport ssh -j fail2ban-SSH Is this because of the way the RedHat tool sets up the firewall? Thanks for any responses. -- "The secret impresses no-one, the trick you use it for is everything" - Alfred Borden (The Prestiege) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Second, have you tried the failed grep expression, i.e., have you tried iptables -L INPUT | grep -q fail2ban-SSH As to why this would fail, you need to ask on the fail2ban mailing list since evidently this appears to be part of the installation. The iptables can be setup by anyone - RedHat simply provides a default set of rules. -- Article. VI.
