.htaccess file
by TE Dukes 30 Aug '16

30 Aug '16

Hello, My home system on a DSL line is getting worn out by bad behavior robots. Awhile back, I created a .htaccess file that block countries by IP blocks. Its 2MB in size. I have been running Linux since Slackware 1.0 and moved to Redhat around 2.0. I started after running a BBS using a doorway for newsgroups. Been hooked ever since. So, today, I tried following the directions for apache.org website, https://httpd.apache.org/docs/current/howto/htaccess.html to move the .htaccess <https://httpd.apache.org/docs/current/howto/htaccess.html%20to%20move%20the %20.htaccess> file to a file located in a directory /var/www/htdocs. I'm just not following or understanding. The .htaccess file works but on a slow DSL, I don't want the hits. I added the following to my httpd.conf: <Directory "/var/www/htdocs"> AddType text/htdocs ".txt" </Directory> And copied my .htaccess to /var/www/htdocs as htaccess.txt In the example from the apache website, I don't get the: AddType text/example ".exm" Where did they come up .exm? TIA

On the machine that contains the physical disks (is that the "server" or the "NSF mount"?) the relevant line from /etc/fstab seems to be UUID=bde58f42-4ac4-4763-b0a8-f83723f0e2a0 /home ext4 defaults 1 2 while on my front-end machine its mseas-data2:/home /home nfs defaults 0 0 where mseas-data2 is the name of the machine that contains the physical disks.

On Mon, 29 Aug 2016 18:59:31 -0400 Pat Haley wrote: > We noticed that all the files were owned by nobody Here are my notes for dealing with this issue: If all users come up as nobody on a nfs mount: Add nfs server name to the Domain = line in /etc/idmapd.conf on both the server and the clients, i.e. Domain = nameof.server /sbin/service rpcidmapd restart /sbin/service nfslock restart /sbin/service nfs restart Also, the complete hostname as specified (nameof.server) must be in /etc/hosts on the nfs clients as well as the server --------------- try /usr/sbin/nfsidmap -c on the client. Since I put this into my /etc/rc.local , I don't have the problem any longer. --------------- 1) /etc/idmapd.conf # Set domain to the domain name shared by your NFS servers. Domain: mycompany.com Set local-realms to the name of the nfs servers you'll be using. THIS WASN'T MENTIONED ELSEWHERE. Local-Realms: nfs1.mycompany.com,nfs2.mycompany.com # make the above changes on all the servers in question. 2) /etc/hosts: list with all the NFS servers you specified in local-realms above. This way DNS errors don't make your servers get hung 1.2.3.4 nfs1.mycompany.com 1.2.3.5 nfs2.mycompany.com 3) Make sure you synchronize your /etc/passwd files so that the account IDs match up or you'll get very strange results. 4) Reboot EVERYTHING. Restarting services was not enough. For documentation's sake, I restarted rpcidmapd, nfslock, and nfs, but didn't get the correct permissions until reboot. It doesn't seem important to run the nfs service on the clients. 5) Client mount: # CLI /bin/mount -t nfs servername:/path/to/share /local/mount/point # /etc/fstab servername.com:/path/to/share /local/mount/mount nfs ro,nolock 0 0 # mount -a -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

NFSv3, or NFSv4? what NFS options are on the server and on the NFS mount? quite often NFS servers force root to nobody. -- john r pierce, recycling bits in santa cruz

ipsets/iptables question
by TE Dukes 30 Aug '16

30 Aug '16

Hello, I have ipsets setup with a set of ip address that are badbots that won't comply with robots.txt This is a home server and these are most likely up to no good. I came up with a script to extract ip address from my access_log then another script to take ips and import them into my blacklist set. (see my scripts in the .htaccess thread) I can set these up as cron jobs but I'm not sure about the following: 1) after importing/updating the set, do I need to perform a, ipset save blacklist Since I haven't changed the rule in iptables, do I need to run these? 2) service iptables save 3) service iptables restart Thank!!

Gnome weather applet stranded
by isdtor 29 Aug '16

29 Aug '16

The Gnome weather report applet has ceased working on CentOS5/6. http://weather.noaa.gov/ says "This service is no longer available". Are there any good alternatives? I liked the applet as it allowed the use of a custom radar map. As I just discovered, the weather functionality of the CentOS6 Gnome clock applet was using the same service.

Off Topic: CentOS Public mirror question
by Valeri Galtsev 29 Aug '16

29 Aug '16

Dear All, My apologies for asking my question on less appropriate list. I did ask it on centos-mirror(a)centos.org, but that list is really low traffic (and slow response probably - I only got acknowledgement of my post...). On the other hand, I'm sure there are many public mirror maintainers on this list who may help me with my trouble. Upon replacing faulty machine hosting public mirrors I have noticed that I can not rsync CentOS (all other mirrors do rsync happily as they did on failed box). I probably have missed some announcement, so my apologies for asking what I should know already myself. Which higher tier mirror should I use to rsync CentOS from (including DVDs) to public mirror I maintain? I use probably outdated source to rsync from. Namely, here is my rsync line (in longer cron job): rsync -aqH --exclude .~tmp~/ --exclude .~tmp~ --delete\ msync-dvd.centos.org::CentOS-incdvd /data/mirror/centos - and I'm getting the following error: @ERROR: Unknown module 'CentOS-incdvd' I also tried what CentOS public mirror wiki suggests, and get similar error: rsync -aqH --exclude .~tmp~/ --exclude .~tmp~ --delete\ us-msync.centos.org::CentOS /data/mirror/centos @ERROR: Unknown module 'CentOS' Independent on this error I also have a bit strange answer in DNS resolution of msync-dvd.centos.org: # host msync-dvd.centos.org msync-dvd.centos.org has address 209.44.106.213 Host msync-dvd.centos.org not found: 2(SERVFAIL) I would appreciate any help or pointers. Thanks a lot in advance for all your answers!

Hello, I have two running BINDs in my LAN, one on my router box and one as VM; both are caching DNS servers, and a few zones are on both, on the box as master and on the VM as slave, but how can I cleanup/flush the growing .jnl files; rndc freeze rndc thaw doesn't work as these are not master ...
