I put this page together just so I won't spam the board anymore begging for help..lol http://bobhoffman.com/vmissue.html This shows a working effort of bonded eths, bridged into a vm, and a few other things. The only missing thing is something on the host that ends up putting the VM internet connection into some kind of limbo. Whether it is hardware related, bug related, libvirt nat

Trying to think this through, hope someone can lend a hand. I have 3 eths I want to bond together and that seems simple enough. eth0,1,2 <-> bond0 , though not sure how this would be for multiple ip addresses needed for the virtual machines... perhaps eth:0, eth:1 etc....to bond0:1, bond0:2 ? then I want to bridge to my virtual machines.... I am going to be using virtual machines, each

Not sure if there is an app like this yet. I want to keep tabs on my web applications and thought of using a 'page checker'/ I was thinking either running a sum on the directory or each file...but thinking a simple date check would be fine. The idea is web application, except the uploads area for photos, never has changes to its files except when I change it. However, if it gets

Okay, Yahoo is bumming me. Only system my mail is having an issue with. All mail is accepted, but junked. I can only think it is the DKIM/Domain keys. It is apparent that the dkim-milter is not part of the centos 5.x distro nor is it part of the mirrors, as far as I can tell. So...have any of you done it with your servers for sendmail? There are some sites that claim to have rpms and I have

I have been reading the threads on here with great ernest about redhat making a move to throw off centos compilations. I read some stories about microsoft wanting to work closer with centos http://www.theregister.co.uk/2011/05/17/microsoft_and_centos/ I have to update to centos 6 due to some needs of clients who need newer mysql and php (and installing them on centos5 was too hard for me). I

Hate to ask, but after reading the last few months of centos history online I am worried. And to learn the lead guy seems to have absconded with the cash and left all the hard working devs high and dry..well that is scary. They all worked so hard and who knows what will happen now. If centos falls I have no choice but to go to redhat. I am wondering if the conversion will be easy or a complete

Perhaps I am trying to do the impossible. centos6, spamassassin, procmail, dovecot, postfix. Postfix, by default, accepts all incoming mail to any user listed in the shadow/passwd and alias files. I cannot find a way to stop that without manually blocking each non wanted user (like nobody, apache) without killing local delivery. For most of the users listed in those files, who cares. However

Hello all, I am down to my last hurdle of my project, backups. I am thinking of three different ways to go and wanted to ask for input on what you think is the better choice. Not asking for 'how to' but more of 'what is best in your experience' The scenario... centos server acting as a virtual host. Virtual machines are webservers and dns servers. All on one machine, all running

Hi all, Well it took a while for me to figure it out, but apparently my logwatch no longer can be mailed locally on my computer as I believe spamassassin is eating it. I can send it out to an email address outside my server though. So spamassassin is only checking incoming I guess. My question is....how do I...or should I.... Make all local mail go straight to the boxes and skip spamasassin

I got a spam today (from a yahoo server, surprise!) with nothing but a single link. http:// 2927755261/ I separated the http so it would not be a link in your email... suggest not going to it without proper measures. it takes you to a record search site. When I look up this number block here, http://www.ip-adress.com/ip_tracer/2927755261 it comes up with a different ip address... The ip

I noticed after my install that the tmp directory was A- not a sticky B- still executable I went and changed etc/fstab to add loop,noexec,nosuid,rw, which I hope is the right thing to do. I rebooted and it looks like it worked. When doing an ls -l on the main directory, the tmp folder lit up all green in putty (cool, I hope) But the chmods I did with winscp will not take effect (they do on

Hi all. I have a new server and am playing with the installation. (centos 6). My onboard sata card has 6 drives attached to it, yet the server has 8 bays. I bought a sata controller card (adaptec) and added it to the mix, adding two more drives. Everything works and all is accessible, but there is one annoying issue. When installing with anaconda, the 2 drives located on the add-on sata card

When I first started using webservers I leased shared hosting. Then I moved to vps. Then to dedicated. In all that I was with various control panels. In almost all cases bugs in those control panels would cause all sorts of issues. (ensim, cpanel, plesk). The load on the server seemed greatly increased (especially with ensim). When I built my first server 4 years ago I decided to heck with

thought you would find this interesting... I get a LOT of political spam on one of my mails due to hosting a political site once. I have been slowly blacklisting the bulk companies and 'the net' of private people pushing political spam. There is one guy who has been sending me stuff for years and I just have it go to the junk folder and deleted..forgot about it. New server, new

I have had the same email address since 1997 (when microsoft stole bob.com from me thanks to network solutions...) In the early days I of course was free with my email and used it everwhere. Fast forward to 2012, some 15 years later. woof..the amount of spam sent to me has always just kept getting worse and worse. On my centos 5 server I just used sendmail with spamassassin and it killed a

I think I have solved my issue and would like some input from anyone who has done this for pitfalls, errors, or if I am just wrong. Centos 5.x, software raid, 250gb drives. 2 drives in mirror, one spare. All same size. 2 devices in the mirror, one boot (about 100MB), one that fills the rest of disk and contains LVM partitions. I was thinking of taking out the spare and adding a 500gb drive. I

So I have been reading the ssh attack thread and finally want to ask about something. I doubt there is a program like this, but I would love to have a program that listens at common ports that I do not use at all...and only allow that program to listen to it, especially the usual ssh port (using a different one for real ssh)... That program would then, upon receiving a 'sniff' or

Hello, Thanks to some nice people on here and other forums I have pretty much finalized my whole mail system on centos 6.x. With all the checks, greylisting, dev/null of any 8+ spam level SA, I still get a few mails. It seems like everytime I enable a new protectant, the mail stops spamming for a few hours...then the spammers decide I am worthy of using better methods against me..and more

Just saw this article http://news.yahoo.com/s/mashable/20101103/tc_mashable/google_helps_autotune_your_web_server (/rant - stupid seo links, lame /rant off) it mentions it is set up for linux distros, notably centos. Anyone use this yet? Affect the auto yum update at all?

Hi all.. I have centos 5.2 There is a cron file that is commented out to auto update the rules of spamassassin Location: /etc/cron.d/sa-update This file is chmod 600, should it not be 755? All the other crons are 755 This line is commented. #10 4 * * * root /usr/share/spamassassin/sa-update.cron 2>&1 | tee -a /var/log/sa-update.log Questions 1- should I re chmod it to 600 or leave it
