Situation: We are providing hosting services. I've grown tired of the various kiddie scripts/dictionary attacks on various services. The latest has been against vsftpd, on systems that I can't easily control vs. putting strict limits on ssh. We simply have too many users entering from too many networks many with dynamic IP addresses. Enter.... thinking about LIDS or Log Based

I've been seeing some random Proliant DL380 G4 64bit crashes. Each time, on the console are messages relating tojbd2/cciss and something about a waitfor 120 seconds. Is anybody else seeing anything like this? Oddly, I can't seem to find this in the logs. I guess it can't write when this happens. -- John Hinton 877-777-1407 ext 502 http://www.ew3d.com Comprehensive Online

Was this with CentOS3 or 4, ie LVM or LVM2? What problems? We use LVM on all our RH9 setups at work. No problems at all. OTOH, LVM2 is a work in progress that

OK, so I did an upgrade to PHP 5.3 on one of my servers. I noticed the uninstall of php also removed SquirrelMail and it won't install under PHP 5.3. Has anybody worked this out with a good RPM or repo solution? -- John Hinton 877-777-1407 ext 502 http://www.ew3d.com Comprehensive Online Solutions

OK, so does anybody have a good firewall rule solution for what we're supposed to be doing with bind these days? Obviously port 53 is no longer enough. TIA John Hinton

For those of you that still are running CentOS 4... I have one system that is still going... there is a problem with the newest release of Dovecot under mbox. Certain spam is causing this error when users try to log on. file lib.c: line 37 (nearest_power): assertion failed: (num <= ((size_t)1 << (BITS_IN_SIZE_T-1))) Rolling back to a previous release fixes these issues. I'm not

I'm looking into adding a cloud to one of my servers. Criteria: security accessible via Windoze, Android Mobile Devices, iPhones, iPads, Macs Preferably something living under one of the better repos, such as epel An active project doing updates and adding features. I don't suppose any of you have ideas for this? ;) -- John Hinton 877-777-1407 ext 502 http://www.ew3d.com Comprehensive

I'm running bind in a chroot environment. It seems that since the Redhat snafu which wrecked bind (yes, I had caching nameserver running as well but not anymore) I have been having problem with my slave nameservers retrieving updates from the master. Looking at the zone records, some are owned by root, some are owned by named. I'm now confused as to what the ownership should be and

I'm seeing a lot of activity over the last two days with what looks to be a kiddie script. Mostly trying to access several of our servers with the username anna. All failed... in fact I don't think we have a user anna on any of our servers. Meanwhile... I'm running Sendmail. This pertains to Centos 4 and 5 servers. I'm also running fail2ban on some and Ossec on others. So far,

I'm trying to get usable reports out of logwatch on this new system. Looks like the reports are running in an 'unformatted' mode under Postfix/Amavisd. I found a couple of programs, postfix-logwatch and amavisd-logwatch. These sound promising. I am running Amavisd as the frontend to Postfix. Is anybody running either of these as a logwatch filter? If so, is it repetitive to run

Hmm.. after all these years I actually have a monitor on my desk beside me going through a couple of KVMs to our racks. So, I hope to make more use of direct console connections instead of shelling in. But, now.... the text has always been huge and the interface clunky. And after a bit of googling around, and file searching on the system, I can't seem to find where or if there is a way to

Seems the script kiddies are now hitting vsftp with dictionary attacks. I had three boxes showing around 12000 attempts from one IP yesterday. My thoughts are that there should be an upstream solution for this which is then supported by the upstream vendor. Yes, I know there are several 'other' solutions, but I'd really like to stay mainstream and use a supported method for

I'm hoping to integrate a shared folder(s) so that we may be able to drag and drop files from various OSs into a shared folder on a CentOS server which can be accessed via Scalix SWA or some other email client. Maybe I'm totally off base with how Scalix stores files in public folders... maybe everything has to be in mbox format for all folders and this could never work..... Anyway, I

I'm having an odd behavior with vsftp on all CentOS 4 servers... maybe 3 too, but I'm not on those much. I am transferring in port mode as I've never managed to get passive to work with a firewall running. Anyway, this is what happens. During normal transfers with few files.. it works perfectly. During the transfer of like a large website with hundreds of files in various

I'm hitting a snag with htaccess. Have created .htaccess and .htpasswd files, set up apache directory options just like always... the exact same setup works fine on CentOS 3, but I can't seem to get it to authenticate on CentOS 4? Am I just being blind stupid (as in not seeing something 'exactly the same') or is there something different I'm missing? I have selinux running

Are there any gotchas with doing a MySQL5 upgrade from the centosplus repostitory? Can this be done as an update via yum or do I need to uninstall and the install? There wasn't anything on this in the readme.txt file. Thanks, John Hinton

Yeah, maybe this is a bit on the edge.... I am discovering several issues with users on satellite internet connections not being able to authenticate via a htaccess/htpasswd system. Some users cannot connect at all, some can connect reliably.. and some are hit and miss.. works one day and not the next. Yet those same users can log in fine if they switch back to their dialup system. Has
