I've been trying to use mod_forensics – [url]-- which has helped on one server track down some one causing the segmentation fault due to trying to abuse FrontPage shtml.dll, but on another server also suffering from regular segmentation faults, this tool has not helped.
What other tools are available to track down the cause(s) of Apache segmentation faults?
I installed net query tool from this site http://virtech.org/tools/
They say in order for ping and trace to work, you must chmod those executables on the server itself to 755. Is this safe or a security risk? The odd thing is, ping and trace works fine from dnsstuff.com or any other network tool site.
I just installed Apache 2.4.4 and it seems to run fine overall. But in my error.log I get about 3 of these every hour or so.error.log:[Sat Jun 15 20:57:44.095961 2013] [core:notice] [pid 31400:tid 16384] AH00052: child pid 1971 exit signal Segmentation fault (11)
track down what causes this? What module? vhost?Otherwise the server seems to run fine. It's on Linux with PHP 5.3.26 and MySQL 5.1.
My website seems to be showing me lots of PHP & SQL errors.
For example, my live-chat shows me:
Warning: session_start() [function.session-start]: open(/tmp/sess_8aa74272d583973018e8f0805a796df2, O_RDWR) failed: Read-only file system (30) in /home/polar/domains/.../auth.php on line 20
I'm getting this error message when logwatch run, --------------------- Kernel Begin ------------------------

Have recompile apache twice, but it doesn't help.

Friend of mine was talking about upgrade to php version 5, but I'm not sure thats the way to do it. Having about 40 accounts/domains and I'm not sure that web sites will work with php 5.
A dedicated server client of mine was telling me that his mysql was corrupted frequently and when his admin tried to upgrade his php and mysql he faced segmentation error. His admin was saying that this was a RAM problem.

One of them is that I get a "Segmentation Fault" when trying to transcode a video in h.264 codec. I can't find much by searching and am wondering if that's a codec issue, or something else.
Post these changes when I try starting apache I get the error - Segmentation Fault - core dumped

we have little problem on our server - from some time it starts reporting some errors:

errors appear 2-3 times every 10min and always in this 4 programs: webalizer, php, spamd, pure-quotacheck
and second thing there is problem with some file caching or sth - for example when we restarts named it reports:
/etc/named.conf:23564: open: /var/named/slaves/slaves.named.conf: file not found
file of course exist but funniest thing is when we remove this line from named.conf and tries restart it, error appear again, even when this line is empty in named.conf and there is no other include of this file even after server restart (without this include in named.conf) it still reports this error
server config: C2Q Q9550, 8GB ram, 2x500GB in hw Raid1, Centos 5.3 32bit, cPanel maybe someone have any idea what it could be, and what else we can check ?
Parallels Plesk autoinstaller emailed me 03:34 to confirm that Parallels Plesk was successfully updated, but ever since then /var/log/httpd/error_log has entries every 5 minutes stating 'child pid xxxxxx exit signal Segmentation fault (11)'.
A while ago i had signed up with the affiliate program of 3ix.com webhosting.
After a few months some commisiions had been confirmed insid their panel, when all of a sudden further access had been denied.
Since two months they keep on mailing lies such as the affilate manager will respond, we are working on it etc.
But now they no longer respond and it seems, that 3ix.com will be vanishing soon with more and more complaints arriving at the FBI internet fraud department.

Anything is should be concerned about or am i not getting my full 512Mb VPS as i should be?
I signed up for their hosting on Sunday morning and completed payment for the first month using hostgators online payment system and paypal.
The payment was accepted and confirmed. An email was sent some time later confirming the account had been set up.
The email specified a user ID for cpanel as well as nameservers which I used to point two of my domains at the new hostgator account.
I used cpanel and FTP to set up the add-on domain, create some email accounts and upload content for the two domains (the same content as on the old servers which should now be shown k-free.co.uk and offshoreharry.com).
All appeared to work fine with no problems. I could use outlook to access email and the web sites were available on the new server (the old server was down).
A day and a half later, I WAS HORRIFIED TO SEE
- the emails accounts could not be accessed - the cpanel user did not work - Hostgator did not email me or attempt to contact me in any way to tell me there was an issue. (they had my valid mobile phone number - there are no unidentified calls in the period concerned). - the web sites that had been pointed at hoistgator were showing a suspended message and spammy hostgator context ads. My non-spam mostly non-ads content had been uploaded to the hostgator account.
One of those domains is freeware software on a site with ZERO ADS that has never been moneterised and sometimes gets 100's of uniques a day.
HOSTGATOR WAS STEALING TRAFFIC FROM MY ad free unmonetized site and showing a nasty spammy ad page.
Not only was I rather angry but also amazed that any company would ever do this. Just think how you would feel if all your sites - pages were hijacked and showing some of the nasty ad pages.
My opinion: Do NOT EVEN CONSIDER using HOSTGATOR.
Checking my yahoo email, there was no email from hostgator saying my account had been suspended (if I hadn't checked it they would have continued stealing the traffic until I noticed).
The only email from hostgator was a request for a copy of my passport or utility bill! I am left wondering if they are really a front for an identity theft scam? I am rather unhappy that they have even my name - address - tel no - paypal email.
I obviously immediately changed the nameservers on the two domains back to the old servers. But since nameserver changes take upto 72 hours to fully propogator, hostgator could still be stealing some of my traffic now. The two sites contain nothing that any T+C I have ever seen would have any reason whatsoever to see as a problem. The two sites are k-free.co.uk and offshoreharry.com for anyone here who wishes to verify this claim.
Hostgator COULD be showing my content instead of their spammy ads - I uploaded it.
Hostgator was mentioned by a few on here and I thought them to be a big company who have a reputation to protect. Are you guys really comfortable with a company who behaves like this. Will they suddenly suspend your sites tomorrow and steal your traffic until you happen to notice?
I have requested to them that they provide access TO MY PERSONAL AND BUSINESS EMAILS on the email accounts I set up. I would also like any log data that was collected. I will report back here what the response to that (politely worded) request is. Giving me access to any email and log data that they have effectively kidnapped-stolen hardly makes amends for the wrong they have already done. Like any other victim of a common thief I may just have to accept that I lost something and will not see it again.
Additionally, search engine robots may have visited the sites and got 404s, any users who dropped by will certainly not be back, the damage caused is ongoing and difficult to fully quantify.
Hostgator did not email me or attempt to contact me (they had my valid mobile phone number). They did not tell me why the account was suspended and the trafic STOLEN. I have had web sites for 4-5 years and have never been involved in anything remotely dubious on the web. You can judge for yourself if there is any reason for them to do this [sites offshoreharry.com, k-free.co.uk]. I had sent at most 10 emails whilst testing the 3 or 4 email accounts I was creating.
Obviously I will never use hostgator or any related company.
My opinion: Do NOT EVEN CONSIDER using HOSTGATOR ... EVER.
- They doesn't support custom installation of PHPMyAdmin on their servers (You MUST use their own admin panel/pre-installed PMA or activate remote connexions)
I'm not sure to understand why PMA doesn't work, but when you create a PHP Script, you must use "MYSQLHOST" as the server host, instead of the usual "localhost". I think that PMA doesn't use the mysql_connect way to connect to the database. So maybe they doesn't allow TCP or Socket connection.
Anyway, that said, if you don't need a custom installation of PMA, you're OK for that point.
- They doesn't support the PHP FreeTypeLib, if you plan to generate image with the GD lib and add some text into it, it may be hard to get a decent result. ( Here I'm thinking of anti-bot confirmation code )
- They doesn't offer any uptime guarantee, and they have no policy in case your server will encounter sporadic down time (just the one I used did for the past 2 weeks)
... And it would be so much a problem if they where offering a reliable service and/or if they where standing behind their costumers. For that, I've been a little deceived.
{ More about the down time experience:
So we have contacted the support team, who said that the site is working well at the moment where we called. They doesn't seem to understand what an intermittent problem is.
They said that, as they doesn't see the trouble at the time of the call, they canot do anything (I was expecting them to place an http probe/monitor or something)
They asked us to take a screenshot of our browser next time that we encounter a down time. ( yes, I'm NOT kidding... a screenshot ! That's what I call technical support
}
I'm not ready to say that they are a bad hosting service, but, they are a little special as you see.
This company has acquired a lot of smaller hosting companies over the last few years including budget only2dollars. Be warned they have ceased responding to support requests, none of the contact links work (even for sales) and they are not even responding to faxes. It is still possible to automatically purchase hosting via web forms of the companies they own. I could be wrong but it has all the hallmarks of a company in trouble and I would be very careful about purchasing any hosting with them until the situation becomes clearer.
It takes a lot to piss me off, and HostGator's done it. I opened an account with HostGator on behalf of a client of mine. Then the client decided he wanted to consolidate a few other web sites to the same server, so I opened a reseller account on HostGator and asked them to move the original account into the reseller account.
My client got billed for both the original (empty) account and the reseller account. HostGator's sales account is refusing to refund my client the money for the original account saying that I neglected to fill out a "cancellation request" form. But, and perhaps this was silly of me, I assumed that when you move a hosting account into a reseller account, they'd close the original account. Or at least TELL you that you had to fill out a "cancellation request" form.
They're referring to some paragraph in my original "contract" with them that mentions this cancellation request form. So, they may be technically right, but it seems to me that asking for an account to be moved into a reseller account would constitute a cancellation request.
Now, let's give them the benefit of the doubt, and that I should have gone back to my original agreement with HostGator and noticed that I was obliged to fill out this cancellation request. Even so, I'm planning on canceling another account I have with them over this I'm so pissed. So by not refunding a lousy $14.95, they're losing a customer for life. Somehow that doesn't sound smart. And I'm so tired of dealing with stupid people or companies. I just won't do it. There are too many other web hosts out there for me to put up with this kind of attitude.
I ordered a server from fasthosts.co.uk in May after speaking to their sales over the phone. Once I had worked out that it was something that we could try I said that’s fine I will order it online. NO NO I was told I can order it for you here and set everything up for you. Great... I gave the girl I think her name was Flik or Flic from fasthosts all my details and she set everything up in a few hours. GREAT
Now here is the bad part...
Tried to cancel the server and have been told that it's a minimum term of 12 month. I have also been charged since then another £79.00. Called my credit card company to try and stop the transactions for now as you can't delete the details on the fasthost control panel.
I have email support so many times and also spoken to them on the phone. I have tried to speak to other managers but they keep saying that there is no ones available to talk to.
My main post is I was not told that this was a minimum of 12 months and would have never agreed to this. I did check when you sign up online and they do place the T&C's deep in their small print. I now know why the girl from Fasthosts wanted to take the order over the phone.
Here is my letter I send to them. Next step is ofcom but if you have any ideas please let me know.
Dear Fast Hosts
I am writing to you in regards to a server that I ordered over the phone with one of your sales people in April. As I recall her name was Flick and her contact number is 01452 561831.
I ordered this server to use as a back up for some of our company files and discussed this with your sales staff. We agreed that getting a Windows server was the best option for what we needed and the server was ordered over the phone.
We were not too sure if the server was what we needed but we thought that we would give it a go and see.
After a week or so I released that we didn’t really need the server as we could use our public folders with the exchange email service that we have with you and if we ran out of space I could always buy some more.
I sent an email to you on 30th May requesting cancellation and received an email back 2 days later advising me that it was a minimum one year’s contact. I have since sent several emails to your support and sales explaining that I was never told that this was a year contact as I ordered on the phone. I was not even told the price.
It's simple... How can I agree to those terms and conditions when I was not made aware of them? I would have never agreed or signed up for a year's contract. I have not used this server and only wanted to try it out. When I ordered over the phone I was never told that it was for a year. Your calls must be recorded and you can check.
I am a consultant for a large mobile operators call centre in ******* and this is poor service.
Please cancel this server and review your sales policies as they are against trading standards.
I also notified you about the cancellation on 30th May and was charged for another month on 4th June. Please arrange a refund for that month to avoid charge back. I am happy to pay the first months payment.
I have other services with Fast Host that I have had for several years. We are a web company and do recommend Fasthosts for UK hosting as we have had a great experience with you in the past.
The credit can be applied to our exchange hosting account domain gsynetwork.com and I believe that the username is ********
Regards
This is the type of reply you get back…… What a joke……
Further to your mail ,
All of our servers are subject to a 12 month minimum term , part of using this server is the acceptance of the terms of service which we operate subject to the normal cooling off periods associated with purchasing products and services over the phone or online. As you have gone beyond this period I cannot authorise the removal of this machine from contract.
At 6pm last night - more than 28 hours ago - my Dedicated Fasthosts server went down.
It's still down.
Despite more than 15 phone calls and several emails, they seem utterly incapable of fixing the problem.
The system drive apparently failed and was replaced today with a new drive. I then rebuilt the Linux Fedora Core and Fasthosts proceeded to add the faulty drive to the server - at my request.
However, after confirming that the drives had been installed and that the server was ready for use, guess what?
It's still down.
So not only do I currently not have a website, but my developer cannot access the failed drive in order to see what can be recovered.
I'm at the point of telling Fasthosts to stick it, but I'm not going to do that because it's their responsibility to fix their hardware and provide the service I've been paying for since 2006.
That being the case, can anyone recommend what steps I should take next in order to hold Fasthosts to account.
I would just like to give you a little warning about justhost.com. This is my experience, but I think I was just very unlucky.
I signed up last Thursday, everything seemed to be great. When signing up it said that everything will be setup within 24 hours. The money was withdrawn and I got a confirmation email from paypal.
After 30 hours I still haven't heard anything from the justhost. I checked a whois for the domain I had signed up for; it still wasn't registered. I chatted with one of their agents. I have mixed thoughts about the agents. They respond really quickly which is great, but they don't seem to have any privileges to do anything. They will only answer your questions and they will tell you who to email if something is needed to be done (from my experience).
The agent said that I should email their billing section. So I emailed them, but I didn't get any response to that ticket.
After 3 days I talked to an agent again. Same story; email billing. But they said everything will be setup within the next 24 hours. I emailed them again...
After 4 days (still nothing had happened) I talked to an agent again. He said he can't find the information about me. So I patiently emailed them my info again.
After 5 days I talk to an agent once again. I started asking why nothing has happened.
After I started getting a little angry over the chat (because nothing was happening) he shut down the conversation.
I then emailed their billing team to say I want a full refund. The refunding worked better than I would expect (since nothing had worked before). My money was refunded on paypal about 24 hours later. They apologized in the email and said that this is very unusual.
I feel that it's very unprofessional to charge a customers credit card and then lose the information about the customer and not doing anything about it.
