Re: [CentOS] Running amanda on CentOS 7: "amanda-udp.service failed."
Hi Robert -
I'm running it successfully on C7 using xinetd. Do you have
documentation for running it directly from systemd? Working xinetd
configuration:
cat /etc/xinetd.d/amanda

# This must be on for systems being backed up\
# by Amanda.
service amanda
{
disable = no

server = /usr/sbin/amandad
# Configure server_args for the authentication type you will be using,

#
# Change the -auth= entry to reflect the authentication type you use.
# Add amindexd to allow recovery clients to access the index database.
# Add amidxtaped to allow recovery clients to access the tape device.

Likewise for using dnf instead of yum, systemctl instead of service, firewallcmd instead of iptables, etc. I wonder how many shell scripts there are "out there" that folks have written or accumulated over the years and which now need to be updated before deprecated becomes no longer available?

So far I have figured out that you have to run TWO instances of DHCP. One instance issues IPv4 and the other issues IPv6.I have not gone so far as to actually set up a second instance of DHCP. As long as you run a router advertisement daemon clients will self- assign routable addresses, you don't really need DHCPv6 if you are also running DHCPv4, you can set DNS (even an IPv6 DNS server) or any other configuration using the DHCPv4 daemon. — Mark Tinberg mark.tinberg at wisc.edu That is true - radvd does cause all my systems to self-assign a public IPv6 address. The problem is that radvd does NOT cause my DNS to get those addresses. The result is I can use IPv6 internally only by giving the address. I cannot use it by hostname. The only exception is the server hosting DNS. DNS somehow knows the IPv6 address of its host and will deliver it on demand. I can ssh to that server by name and get an IPv6 connection. SNIP Ran into this a couple of years ago when I was playing with IPv6. I guess it hasn't changed since then. The problem is that dhcpd and dhcpd6 are two separate services and dhclient only talks to one of them. So, you can get your client IPv4 addresses into DNS or you can get your IPv6 addresses in but not both through DHCP and dynamic DNS updates. There is probably a way to get both addresses in using a shell script that runs on each client but I didn't see a way to do it securely.

Programs share the loaded executable code across all instances and you pretty much always have some shells running on a linux/unix box - a few more won't matter. Just pointing out one of several approaches to respawning a daemon without the overhead of systemd. I went with this approach since the problem is not with radvd or its init script but with my IPv6 tunnel provider. I wanted something that didn't require modifying any of the installed bits. This approach also means that updates to radvd and friends don't overwrite my modifications. Just playing with the IPv6 stuff so having it down for up to five minutes also isn't a problem. The source of the problem goes away when my ISP provides IPv6 and I don't need to tunnel IPv6 in IPv4 anymore. I look at systemd as being yet another nuclear fly swatter.

SNIP Personally, I would: a) Not use Cent* b) Ask a trademark lawyer Best advice so far IANAL of any kind and specifically not a trademark lawyer. As I understand it, trademark law differs from other IP law in that the trademark owner must defend their trademark or they lose it. It's great when a trademarked word becomes synonymous with something (Kleenex, Xerox, etc.) but it also means the company that owns the trademark has to actively go after (CD) anyone who uses their trademarked word. This also apparently holds for companies that deliberately create a product that has almost the same name as a trademarked product (I remember seeing a picture of a tube of Colgade toothpaste in the article discussing this). So, while CentAP or some of the other suggestions may not infringe on CentOS, you could still get a CD from a Red Hat lawyer telling you not to use CentAP. Unless you can afford a really good trademark lawyer to fight the CD, you'll have to discontinue use of CentAP (or whatever). Your choice. Clear as mud? That's why lawyers make lots of money.

I'm guessing fibre channel through a FC switch. Is this correct? With the correct software both servers could end up seeing the library as their own this way. 4) You can try doing a rmmod sg followed by a modprobe sg.

You may be getting a failure message since the interface isn't up when dhcpd gets started. I only find NetworkMangler useful on systems that regularly change connectivity like my laptop. I just find it gets in the way on stable, wired networks. The same problem can occur on VMs just because the virtual interface comes up more slowly the a real hardware device. That is, eth1 sn't there yet when dhcpd starts. If you specify the correct interface that matches the IP address you want DHCP services on in /etc/sysconfig/dhcpd you shouldn't need a dummy interface/network specification. I notice that you mention /etc/dhcpd.conf but the location of the configuration file moved to /etc/dhcp with RHEL6/CentOS6.

I'm more of a c-shell guy but a for loop uses white space (either newline or
space) as the delimiter. One of the other responses suggested an alternative
loop construct. Alternatively, the find command with the appropriate commands
in either a script file or just following a -exec. Something like:
find . -type f -exec `new = `echo {} | tr [bad chars] [replace]`; mv {} $new;
echo old: {} new: $new \;
The above needs lots of work but this way you don't have to visit each

No sure why but logwatch doesn't consider any of the apcupsd messages as reportable so you have to look at the log file to see what the UPS is reporting. If you're lucky, the above is all that's going on and the easy fix is to update the battery date. I just had my APC UPS blow a battery sensor and decide that the battery was no longer present only to then immediately decide it was indeed there and cycle through battery attached/unattached continuously.

Re: [CentOS] Dealing with brute force attacks
James B. Byrne byrn...@... writes: Over the weekend one of our servers at a remote location was hammered by an IP originating in mainland China. This attack was only noteworthy in that it attempted to connect to our pop3 service. We have long had an IP throttle on ssh connections to discourage this sort of thing. But I had not considered the possibility that other services were equally at risk. Researching this on the web does not reveal any comprehensive list of vulnerable ports or services. Most discussion centres on ssh, then some on ftp, and relatively few regarding pop3. So, my questions are these: 1. Should I throttle all new connections regardless of destination ports? In other words: are there any legitimate reasons that a single IP would require more than one new connection every 30 seconds or so? 2. Moving pass the obvious and unhelpful everything, what services are particularly vulnerable to these types of attacks? Does a list exist anywhere? Regards, Hi - I went though a similar process back when the DNS cache poisoning attacks were coming fast and furious. The question to answer is, Are there legitimate reasons why the same IP address will apparently make multiple connection requests for a particular service? For DNS the answer was a resounding no since the source nameserver should cache the results of the query. For POP3 the answer is more dependent on your particular organization. As an example, is there a remote office that will generate a number of connection requests when everyone egts to work in the morning; all apparently from the same IP address? If there are no such legit reasons why a number of requests could occur in a short period of time, a simple firewall throttling rule may be sufficient. I have an article on my blog describing the firewall rules I used to throttle and then block DNS cache poisoning attacks at: http://davenjudy.org/davesBlog/node/41 One of the other replies also suggested fail2ban which may be more appropriate anyway since you really want to look at failed logins; not just connection attempts.

I appreciate the suggestions but I'm really quite happy getting the list just once a day in digest form rather than have a steady stream of e-mails with intermittent flurries of activity that comes with getting the e-mails individually. There are also a number of benefits to letting some topics settle out before I get a chance to see them or respond that I won't go into at this point. One I will point out that you will still need to contend with is as follows. People (like me) who read the digest frequently are able to take a step back from some of the discussions and bring together multiple responses and several otherwise diverging threads. The threaded message view is based on the sometimes false assumption that once threads diverge they cannot later merge. Several times I have ended up consolidating replies to several divergent threads because that's where the answer was to be found. The threaded view of a discussion may be a nice way of organizing the elements of the discussion but it doesn't necessarily reflect the object of the discussion which is to find an answer. One of the other responders pointed me to Gmane as a way to reply to individual postings. I'm using Gmane to compose this and will attempt to continue using it in the future (I've been known to forget such things).

I found http://apcmag.com/how_to_dual_boot_linux_and_windows_xp_linux_installed_first.htm?page=1 and it seems straight forward enough, although the description is for Ubuntu. The problem as I see it, is that the how-to differs from how CentOS looks in /etc/grub.conf and the boot-loader in Ubuntu with respect to making grub work again after the Windows install. I found Tldp.org mentioning dual-boot plenty, but most or all articles listed are using lilo as a boot-loader, which seems a bit obsolete and besides I can't quite translate the instructions from lilo to grub. 8-/ Basically, what would I need to change in the how-to from apcmag.com above?? Thanks for any pointers. As noted in other replies, Windows not not play well with anything else. Your best bet would be to disable/remove/disconnect the drive with CentOS and then do the Windows install to the other drive. Once Windows is installed, you can reconnect the CentOS drive and then easily edit grub.conf to boot Windows using the chainloader directive. This approach will only work if there are no primary partitions on the CentOS drive that Windows recognizes. Windows (just like DOS) assigns drive letters to partitions in drive number order starting with the primary partitions and then moving on to the extended partitions. The bottom line is that you want the first Windows partition on the non-CentOS drive to get assigned drive letter C: when Windows boots. As long as Windows doesn't recognize the partition type (e.g., ext3), no drive letter gets assigned. The problem with suggestions to just install Windows and then either use another boot loader or repair the grub installation is that you are stuck doing that work through Windows. My experience has been that Windows isn't as easy to work with for making changes to the boot loader and any approach that overwrites the Windows boot loader may leave you with Windows not being bootable. The approach I described above leaves the Windows boot loader in place although you may need to edit C:\boot.ini to make sure it can still find Windows when both disks are present. Here is the grub.conf that I use on my laptop. The internal drive boots to either CentOS or Windows while Fedora 10 and Ubuntu are on an external USB drive. # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition.

TIA You didn't wait for the official release announcement ;) Good one!! :-) Wasn't trying to upgrade to the newest release. I run a 'yum update' daily. I only have Centos repos installed so I don't know how I have a version of nss newer in 5.2 than 5.3. As someone suggested in a later reply, I'll wait a day or two and try again. Thanks Lots of noise on the list today. I ran into the same problem when I attempted to yum update my workstation last night. I worked around it using the old old rpm dependency hell technique of retrying the update but sequentially excluding each dependency as the various update attempts revealed them to me. I finally got a working update with: yum --exclude wxGTK --exclude nss-devel --exclude 'rpm-*' --exclude popt update; date wxGTK is excluded since I'm also running audacity 1.3.0b. The remaining excludes got me around the nss-devel problem. Got up this morning and re-ran my yum update with only wxGTK excluded and it worked just fine. Literally as I was typing this e-mail, the update for my laptop did the same thing (complaint about a missing nss-devel). My other systems all required changing /etc/yum.repos.d/Centos-Base.repo to use baseurl instead of mirrorlist before the update would even run. I made the same change on the laptop and the update is now progressing as expected. The laptop and my workstation are the only x86_64 installations. The remaining systems are all 32 bit. Since the problem still occurred on my laptop but went away when I switched to baseurl, I wonder if one of the mirrors has a bad configuration.

I have a test system: Centos 5.2 on an OQO, that has been hanging hard. I have to unplug it and pull the battery so I can then cold start it. I assume this also means that the system runs as expected if you don't take any of the actions described below. This last time all I did was open a terminal window and SU to root, then start the lastest build of SIP Communicator (which uses JRE 1.6.0_10). I was not even making a test phone call at the time. Any chance of trying an earlier version? Especially one that uses an earlier JRE? Oh, and the system only runs IPv6, no v4 addressing. And what happens if you enable IPV4? If possible, can SIP Communicator be configured to use IPV4 instead of V6? If so, does the problem persist? So how do I find out what is causing the hard lockups? I'd start with enabling IPV4 addressing since it's fairly trivial to do and then work back toward running an earlier version of the program. You may find something like the JRE wants an IPV4 connection (just wildly speculating here). Cheers, Dave -- Politics, n.

Typically, once a source IP has queried a DNS, the result is cached for the time to live (TTL) of the resulting record and the query should not normally be repeated. Given this, I added the following rules to my firewall: ... # Block cache poisoning attacks # Drop repeated DNS requests -A RH-Firewall-1-INPUT -p udp -m udp -m recent -i eth0 --dport 53 --update \ --seconds 660 --hitcount 7 --name DNSTHROTTLE --rsource -j DROP -A RH-Firewall-1-INPUT -p udp -m udp -m recent -i eth0 --dport 53 -j ACCEPT \ --set --name DNSTHROTTLE --rsource ... Note that eth0 is my external NIC so these rules only fire for DNS requests that are not from my local network. I came up with seven queries in eleven minutes was a reasonable sign of a cache poisoning attack. Your mileage may very. These two rules replaced about 30 IPs in my blacklist and are completely automatic. The funny this that a lot of the brute force cache poisoning attempts just keep banging away so the source IP stays on the blacklist. Every once in a while I'll see a new IP address hit seven attempts and then the blacklist rule kicks in and they're never heard from again. Cheers, Dave -- Politics, n.

[CentOS] Scripting Oddity
I've been playing around with qemu and wanted to make the guest OS
instance visible on my network. This meant getting bridging and tun/tap
working. After getting things working by pasting command from the
CentOS wiki article plus adding a few enhancements, I decided to capture
the process in a shell script that would be suitable for a user in the
sudoers file to fire off. Not sure why (which is why I'm posting this)
but I couldn't get the same result from the shell script as I got from
pasting commands onto the command line or using the shell history.
After a lot of very tedious debugging, I finally got the script to work
by adding a couple of short sleeps at selected locations. The script
now looks like:
cat upBridge.sh
#!/bin/bash
#
# Script for setting up a bridge accessible by a qemu VM.
#
# First, make sure we're starting with a clean slate.
/usr/bin/sudo /sbin/rmmod bridge
/usr/bin/sudo /sbin/rmmod tun
/usr/bin/sudo /sbin/service network restart
#
# Grab the IP address of the given interface so we can restore it later.
#
oldIP=`/sbin/ifconfig $1 | /bin/grep 'inet addr' | /usr/bin/awk -F \:
'{print substr($2,0,index($2, )) ; }'`
echo $1 currently has IP address $oldIP
#
# Create the bridge.
#
/usr/bin/sudo /usr/sbin/brctl addbr br0
/usr/bin/sudo /sbin/ifconfig $1 0.0.0.0
sleep 2
/usr/bin/sudo /usr/sbin/brctl addif br0 $1
#
# Stop any dhclient still running.
#
/usr/bin/sudo /usr/bin/killall dhclient
#
# Get and IP address and routing information for the bridge
#
/usr/bin/sudo /sbin/dhclient br0
#
# Make sure the tun module is loaded, assign it to our user and bring it up.
#
/usr/bin/sudo /sbin/modprobe tun
echo Did tun load?
lsmod | grep tun
/usr/bin/sudo /usr/sbin/tunctl -b -u $USER
sleep 2
/usr/bin/sudo /sbin/ifconfig tap0 up
#
# Connect the bridge and the tap.
#
/usr/bin/sudo /usr/sbin/brctl addif br0 tap0
/usr/bin/sudo /bin/chown $USER:users /dev/net/tun
/usr/bin/sudo /sbin/iptables -I RH-Firewall-1-INPUT -i br0 -j ACCEPT
#
# restore the IP address of our normal interface.
#
/usr/bin/sudo /sbin/ifconfig $1 $oldIP
So, my question is, why do I need to have a short sleep in these two
locations in my script?
Without a sleep after the ifconfig eth0 0.0.0.0, eth0 retains its
original IP address instead of having no address. The qemu guest VM
still functions correctly but the host system loses connectivity.
Likewise, without a sleep after the tunctl command, the device
/dev/net/tun isn't present when the next command executes. With the
sleeps the script executes as expected and sets up the bridge. Without
the sleeps the script fails.
Oh yeah. There's another script called downBridge.sh that undoes the
bridge if anyone is interested.
Cheers,
Dave

I suspect that this means that I'm missing some package that I should have installed, but what is it? I went through something like what you're going through when I first put CentOS on my now somewhat old HP laptop. Do an lspci -v and find the entry for your card reader. Then check to see if it is supported by the kernel (look in /boot/config-kernelVersion). If it is, I don't have an answer for you. If it isn't, check to see if it's supported by the current kernel from kernel.org. If it still isn't, it's not going to work until someone implements support for that particular card reader. If it is, you have the option of building and running a custom kernel using the source from kernel.org. There are lots of how-tos on how to make this happen. That's what I did on my laptop until support for my card reader got into the RHEL/CentOS kernel. Cheers, Dave -- Politics, n.

I posted more about how I solved the issues on my blog at http://davenjudy.org/davesBlog/node/40 There could be an issue if some package other than audacity needs the more recent version of wxGTK but I didn't have to force the removal of the package. This tells me that the easiest way to resolve this issue may be to just hold wxGTK at 2.6.3-1 until the next version of audacity is ready for prime time. Anyone know of any other packages that are dependent on wxGTK and need the most recent version?

Finally, get a free mail account at your provider of choice (Google, Hotmail, whoever) and use it for testing both sending and receiving mail. Cheers, Dave -- Politics, n.

I'm working with some folks to develop a web site with a very similar configuration (Apache, Drupal, MySQL, not sure which Linux distro is underneath it all though) that's hosted by IX web hosting. We are seeing very similar behavior. It has gotten better since we complained to IX but we still see a significant lag the first time the site loads. The fast load on subsequent visits could be explained by Drupal doing some caching of needed items so it doesn't have to go to the database. The initial site load time became much more noticeable after IX took some kind of hit on their DB server. All we know is the site suddenly couldn't connect to the database, they fixed something on their end and the database came back but we've had the long lag for first load ever since.

You can swap cdrom from qemu monitor. I haven't tried, but I think the same thing can be applied to usb.. It looks like the qemu monitor should let you either eject the device or delete/add the USB drive using usb_del and usb_add. I wasn't able to get it to work. W2K gives me a control to unmount the thumb drive in the system tray which makes the drive disappear from W2K. Unfortunately, attaching a new drive or just reattaching the old drive isn't recognized by W2K. qemu monitor tells me it unable to add the new device or delete the old device. If hot swapping a USB drive can be made to work with qemu, swapping a USB drive will still be ugly. The USB device number assigned by the kernel changes each time I swap thumb drives. This isn't too bad but access to /proc/bus/usb/usb_bus_number/usb_dev_number is root:root with permissions rw-r--r--. This means that each time I swap the drive I have to chmod the new USB device entry. I don't see this changing even if I can get qemu to let me add the new device. I'll have to try using qemu monitor to swap a CD-ROM at some point in the future. Usually I only use W2K and IE under qemu to access those few sites that still only work with IE (e.g., my state's income tax site). Cheers, Dave -- Politics, n.

In Win2k, Micro$oft finally got up to speed and most flash drives will work with it, but XP is better. Fair enough. Out of curiosity - do they work in W2K out of the box, or require some update?

It might be worth experimenting there although you don't mention having changed anything. On my system, there seems to be a little flakiness re the sound. Sometimes just clicking the Open Volume Control and muting/unmuting a few things fixes it. This seems to be needed less with recent updates to the 4.x stuff (again, 32 bit). There is a kernel parameter that may have affect - see the end of this post. I wish that I could be more helpful, but I just use the stuff. :-( Turns out it was a wiring problem. Weird that it causes the driver module not to load. The original owner suggested that might be the problem so, after trying a CentOS 5.0 kernel and building and trying a 2.6.24.4 kernel I decided to crack the case. I pulled the cable for the case's front audio and mic off the motherboard and tried with that configuration. The good news was I no longer got the error documented in my earlier e-mail but still no sound. The case's front panel audio had two different connectors so I decided to try the other one and suddenly I had sound. No idea what the difference is between the two connectors. What's really strange is both front audio connection jacks are keyed correctly for the front panel audio out on the motherboard. It's just one works and the other doesn't.

longer works (worked with CentOS 5.0). dmesg gives me:
