I did a goole search and found several hits telling me about this error I am getting

I am having issues getting yum to work with the repos for fail2ban and denyhosts. I followed the centos link on installing/cfg repos. However every time i run yum install fail2ban or denyhosts it does not find the software. I read in several google searches that I should be able to install it using yum. Is that info wrong? These are the link I was s reading too from centos. [URL]. I know I can download the rpm or a tar file but I would like to keep it in sync with yum if possible. May be I have the wrong repo? CentOSPlus is enabled also.
View 3 Replies View RelatedSo I installed denyhosts on my system and I ssh to it fine. Then all of a sudden I got an email saying my ip was added to the /etc/hosts.deny file.I have no clue why. I did not fail the login. So I had an open session and put it in the /etc/hosts.allow file and tried to ssh back in no problem.Then I logged out and all of a sudden I got the email saying my ip was added to the hosts.deny again. Now I am kicked out of the system..
I am guessing I cannot get back in until I get to the console and remove it. I can power on and off the system remotely but I enabled the chkconfig denyhosts on option so it starts on reboot. No remote console is setup.So it looks like I am hozed until I can get to the console, bummer as I was trying to set up a spacewalk server on it. I cannot get to the console for a few days so if anyone has ideas how I can get back in let me know. But denyhosts seems to be working as designed.
This was a default install I did not configure anything funky. Just changed the email to root and started it.I thought about changing my client IP but that wont work as I only have ssh passed on my router to that IP so if I change the client IP I wont get into my routing machine.I think i answered my own question but just thought I would askI guess my real question is why would denyhosts block my IP when the login did not fail and how do i configure it so this does not happen again.
I've been using the denyhosts software for about 8 months to block IPs that are trying to connect to my network that shouldn't be. I'm having trouble with it today for the first time and I can't track down the issue.It is installed on the main server which is the outside IP for the network as well. This should allow me to SSH to the hostname/network IP, or the NAT IP as well. It worked fine up until this morning when I started to work on an ftp server, as far as I know I didn't make any changes that should cause problems.
hosts.deny starts with no 192.x.x.x addresses in it. In allowed-hosts for denyhosts I have entered 192.168.1.1 so that the router should never get blocked.I can SSH to the hostname perfectly fine, connection doesn't drop or anything.If I SSH to the NAT address the connection hangs there while the IP address gets added to hosts.denyI can confirm 100% that I was able to SSH to my NAT from within the network with no problem, now it seems to throw the router IP into hosts.deny if I try to connect from within the network using the NAT.Here is the error that I get in /var/log/securesshd[9272]:d not receive identification string from 192.168.1.1I did update my system recently which may have changed the way some files behave, I will try updating Denyhosts as well. It looked like the address being blocked was an IPv6 since it was showing as:sshd[9201]: refused connect from ::ffff:192.168.1.1 (::ffff:192.168.1.1)

View 1 Replies View RelatedI've been using Deny Hosts for a couple of years now without trouble. My router forwards SSH calls to host tock on my LAN. My router's internet hostname is michigan. I keep an svn repository on tock and access it through michigan. In this way I can update my repository when I'm at home or away.Just today, however, whenever I try any ssh to michigan, I get a closed connection and find michigan in my hosts.deny file. I delete it, make a successful connection, but then on my next attempt - there I am in the hosts.deny file again.
I've worked around it by putting michigan into my hosts.allow file, but I would really like to know what's going on. I've configured Hosts Deny to lock out IPs after three failed attempts, but it is locking out michigan after one successful connection.
I have recently installed denyhosts to help guard against bruteforce ssh attacks on my Fedora 12 server from the Fedora repositories. If I manually start denyhosts (as root) using: /usr/sbin/denyhosts.py --daemon
it works fine. The denyhosts log file is created and indeed the /etc/hosts.deny file is updated. However if I make attempts to start denyhosts automatically upon the server restart denyhost fails with a permission denied error for /etc/hosts.deny (error 13) I have tried using chkconfig to enable /etc/init.d/denyhosts on run levels 3, 4 and 5. I have also tried including the line:
/usr/sbin/denyhosts.py --daemon
in /etc/rc.local Both of these attepts report the same error. anyway to automatically start denyhosts or know why this problem might be happening?
I have setup Denyhosts to run on my server, and have been using it succesfully for the last few weeks, to allow me to ssh into my server from my home dev machine.
This morning, I accidentally typed my password incorrectly three times - and ended up being locked out of the system (tghat was ok, because that was what was supposed to happen). I logged into the server via another way and took the following actions (in the order given)
/etc/init.d/ssh stop
/etc/init.d/denyhosts stop
removed my IP address from /etc/hosts.deny
/etc/init.d/ssh start

I've been running denyhosts on Ubuntu 8.04 servers without any problems using the how-to found hereow that I have a new Ubuntu 10.04 server running, I thought I would just install denyhosts from the Ubuntu repository not realizing that the paths and filenames of the install are different from the how-to I am used to using.I figured out what the name of the new denyhosts config file is (at least new to me) and the new location, but I'm not sure about the "allowed-hosts" config file.Does anybody know where the new path for this file is and whether the filename is still the same?

i restore Centos from backup file,after i have finished,i start centos, it can't start and repost error: IO-APIC + timer doesn't work! Boot with apic=debug and send a report. Then try booting with the 'noapic' option
View 11 Replies View RelatedI move to Centos in October 2009 from Windoze and machines with 36 bit words. I now have 3 servers with Centos 5.5, 5.5. and 5.2 plus a laptop with 5.4 and am currently trying to put Centos on a 10.2" Netbook running Win XP.
On two 5.5 servers I notice a different graphical start-up process. One starts, from the text announcement "Centos 5.5 Final" with a blue Centos screen. If one displays the text it is shown with a thick blue Centos coloured border. The other starts up with text and stays in text mode until it has displayed the text log-in prompt and then after a few seconds presents the Centos GUI log-in screen.
My question is how can I make both servers, both ostensibly running the identical operating system, behave identically ?

I have a CentOS 5 machine here, running Gnome. It has the proprietary ati screen driver, driving twin monitors in Xinerama. I have it set to auto-login as me. It has worked fine for ages.
This morning when I booted it up, instead of getting my usual desktop, I got 2 completely black screens, with an X-shaped mouse cursor. The cursor will move between the two screens OK, so I guess X has started, but I have no display manager. Or something. I have never really understood how X starts up, so I am now at a total loss as to how to find out what is wrong, and fix it. I can get to a login prompt by pressing Ctrl-Alt-F2, but I'm not sure which files to mess with when I get there. I have studied the X log in /var/log/messages, but there are no errors in there.

I'm a freelance now. so i installed CentOS in a portable hard disk for the convenient i move to new place and start my job.
But i found the grub of CentOS is installed on ...uhm... my Computer(?)...actually on my first Hard Disk(start up windows with MBR). and maybe the data of grub was installed on my portable hd. so i can't start CentOS on another computer and i even can't start windows without portable device...
so... is there any way to start up this OS without GRUB? or where should i pay more attention to when setting up to let CentOS could be moveable?
