We're looking to bring in a T3 for our small startup hosting company and when we do traces from multiple location it always runs through a cox.net IP and it concerns me because I dont want our customers to believe they're being hosted on some kids cablemodem. What do you folks suggest, the IP is 64.19.96.5 to their outer router. Should it be a concern that we route through everyone through a cox.net IP?
I have a problem with the traceroute for 72.36.229.84 . Some useres can reatch it, but not all.
I 've attaced 3 routes under that isn't working and 2 that work. Look at the routes that doesn't work, they all stop by gblx.net ( String 9 - 10) Working routes doesn't use gblex.net My question : What should i do, what can i do ? Is gblex.net the problem ?
Not working route : emil@egenhost:~$ ping 72.36.229.84 PING 72.36.229.84 (72.36.229.84) 56(84) bytes of data...
During these periods of inaccessibility, ping/traceroutes from multiple physical locations around the world show 50-100% packet loss.
During times when the server is accessible, ping times are anywhere from 100ms-700ms and the server does not remain accessible for very long.
I gave my provider traceroutes and pings for those times when it was inaccessible and accessible and they stated it was not on their side. It was on a hop in the middle between me (and apparently everyone else, since multiple locations around the world were used) and my server. They say it is not in their control and they cannot do anything about it.
I am reasonably sure this isn't just me or my VPS. I am on the phoenix node of PrimaryVPS.
The latest traceroute I did showed something new - a router advertisement claiming the TTL was exceeded....
I am still trying to diagnose a problem some members have on my forums, when they load a page it will load a grey screen (my background color) and stop, after 15-30 seconds+ it will finally load the page
i opened a ticket with my server co and they forwared it to the NOC, NOC said it was apache config problem, server co said it was fixed and was due to apache log reaching 2GB limit, logrotate installed
same problem still existed, opened tk with server management co, they tweaked httpd.conf and disabled logs, problem still exists
I asked 3rd management co about it, changed some settings in httpd, said it may be due to ads on the sites, i took out the ads and a stat script
problem still exists, the thing is the problem exists with some users and not others, doing speed tests to the server shows it is very quick, load is low, no i/o wait and i just installed the second GB of memory so memory is fine
this is happeneing to users on seperate forums, one using vB, one using IPB, so it is server/ hardware related, AMD barton 3000, with 2GB ram, nowehere reaching the bandwidth limit or 10mbps port speed limit
any ideas? doing tracerts to the server shows a timeout before the sites IP address, every time, but doing a tracert OUT of the server shows no time outs....
I run tracroutes to many IPs often, anyoone could whip up a script to run traceroutes by entering IP and hitting enter and ability to cancel the process (as it gets stuck sometimes) and enter another IP to trace to?
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'm looking into knownhost and they offer twice the bandwidth in their California option for the same money. Jay from known host said I should pick the one with the best ping times. I'd like to put the information here so someone might perhaps tell me what my best choice is.
I'll put the stats here and then if you could tell me which one is better (Texas vs. California) that would be great.
But if you think that the times between the two are only marginal (both real good), then could you help me decide about getting double the bandwidth for the same price.
I know nothing of course, but the two data centers look like their both giving great speeds (Texas being better though). But perhaps both speeds are great. If that's the case, can anyone tell me why someone would not take the higher bandwidth offer?
Thanks, I really appreciate any help with this!
Here is the info...
Texas (ping):

I was wondering if anyone out there knew of any programs out there that can monitor and record ping times to various server IP's and couple output say a simple graph. There used to be this website I used that you could simply go onto there site, and register, and put in your servers ip addresses and it would output a simple graph that showed latency, loss etc for any ip you put into there system and displayed a web based mrtg type graph. I am having some troubles at one of the datacenters that I have some co-located servers at, and would like to show them how much packet loss they are having at a given time, or over say a 24 hour period.
I'm looking to set up some custom monitoring stuff that ties into my existing systems, so that's why I'm not looking for established monitoring services.
I'm looking for a shared environment where I could ping and trace to my equipment, either from cron or a background daemon which I'd write in perl, python, etc.
I'd also want it located somewhere on the left coast or Texas.
Does anyone know any hosts that would meet the above?
Is there a way to page results from ls through FTP similar to the way you can in your shell by using ls | less (or ls -l | more)? When I try ls | less through FTP, even on a linux server, it wants to output to a local file?

This is a follow-up to my original thread [url] regarding my client's experiences with HostWay.
I simply can't believe all of this, and I went through it.
The low points of the whole thing work out like this: In order to set up an SSL for my client's site, we needed a dedicated IP. If you do a traceroute on my client's URL, it resolves to someone else all together. Int he mean time, I tried to purchase an SSL through HostWay, and when they didn't respond in a week and a half, I e-mailed cancelling the order, and purchased a (thankfully) inexpensive SSL from GoDaddy. I got an e-mail back within hours from HW saying, literally, "We never processed your SSL order, so there's nothing to cancel. Let us know if there's anythig else we can do."
As I mentioned before, e-mail support seems to be handled off-shore, and it takes over a week for most answers. Phone support gets you, I found out, a service in Florida.
While the people I dealt with on the phone were always professional and polite, they literally could do almost nothing. I was told several times, "I have to e-mail someone in Chicago - no, I don't know who it is, all I have is an e-mail address."
Back to the SSL - seems HostWay already installed one on my client's site at some point - and it had nothing to do with my client. You could visit a secure version of the site, and it would tell you not to enter, as the cert didn't match the site.
My client and I both were on the phone with the Florida 800 number for hours at a time.
Average wait time to speak to someone was 30 minutes or so. I'm not carping about that part - but they were feeding us false information which was supposedly fed them from "Chicago." Specifically, I told them on the phone and via e-mail that the IP didn't resolve correctly, and that the old cert needed to be removed before a new one could go on (and only their SSL team can install certs, supposedly).
They told my client that the GoDaddy cert was causing them problems, and that it needed to be cancelled before they could install one of their GeoTrust certs. I nuked it - even though I knew better - and of course nothing was done. They lied to my client for several days, saying the new cert was installed (even though I knew it wasn't, and I told my client so, and showed them HW's tech was passing on false information).
This situation went on for almost two weeks. Finally, Monday night, my client got a supervisor based in British Columbia, Canada, who promised that he would walk "the tech admin" through fixing the problems that night. But that was only after my client threatened to pull his account.
Well, the IP is still screwed up, but they replaced the cert that night with one for which they charged my client an arm and a leg. The CC processing company is happy, so we let it ride, and they're now processing payments over the web.
If this is confusing, it's because I condensed many long days and nights into a few short paragraphs. Let's just say that HW didn't have their thinking caps on tight, because they committed to their preposterous stories to e-mails which we all received.
Later this year, at a conference to be held in Canada, a committee of nuclear power station operators will be discussing whether or not they should keep HW as the host of their site. Gee, I wonder what the consensus will be.

OPEN FILES LIMIT Current open_files_limit = 10000 files The open_files_limit should typically be set to at least 2x-3x that of table_cache if you have heavy MyISAM usage. Your open_files_limit value seems to be fine
TABLE CACHE Current table_cache value = 1024 tables You have a total of 721 tables You have 93 open tables. The table_cache value seems to be fine
TEMP TABLES Current max_heap_table_size = 16 M Current tmp_table_size = 32 M Of 212 temp tables, 0% were created on disk Effective in-memory tmp_table_size is limited to max_heap_table_size. Created disk tmp tables ratio seems fine
TABLE SCANS Current read_buffer_size = 1 M Current table scan ratio = 17754 : 1 You have a high ratio of sequential access requests to SELECTs You may benefit from raising read_buffer_size and/or improving your use of indexes.
TABLE LOCKING Current Lock Wait ratio = 1 : 76 You may benefit from selective use of InnoDB. If you have long running SELECT's against MyISAM tables and perform frequent updates consider setting 'low_priority_updates=1'
how to make the changes in red? My server works good for awhile, but then gets REALLY REALLY slow.
I run the top command when memory usage seems to be running high on my server. I look at it and blink and have no real idea whether things are "okay" or not.
I apologize for the extreme basicness of this question. At the same I would love to have some kind of personal benchmark of "okayness" for this server so I can look at top results when things are dreadfully wrong and recognize it.
Based on these results would you say the server is holding up under traffic? -----------------------------------
Now we do notice, that quite frequently, the connection times out or the server responds slowly. A friend of mine said the VPS could be the issue of this.
I ran a ping test today for several hours, sending one ping with 16 bytes with a timeout set to 3 seconds.
From 18000 pings sent (5 hours), 120 failed. Which comes to one failure in 150 pings, or one failure every 2.5 minutes.
Is this still an acceptable failure rate or do I have reason to contact our VPS provider? According to our own usage statictics, we are not using much of the server's capacities.
I just read Peer 1 financials -they got big this year!
Does anyone know how many actual customers they have? The financials say $74.36 Million... with 9,000 customers... humm... they must have more than that? Just curious.
I'm new to server administration/security/troubleshooting, so I have included a lot of info here hoping it will help.
This started because a Linux VPS with CentOS and Exim crashed after only 3000 emails were sent (of 30000) total
I ran a netstat and several times I get three separate ips with the only difference being the last two digits and the port number: 86.104.230.29:59009 86.104.117.45:18065 89.37.137.157:41593
As far as I can tell they are from Romania, and there are several connections.
I have posted a lot of information below, if someone can take a look and give some ideas, it would be very much appreciated.
Hope there is a DNS expert about that can make sense of what I observe and give an unbiased opinion.
We are currenlty evaluating hosted DNS providers. Anycast DNS seems like a great feature to have and we want fail over too. Narrowed down a list of possible suppliers: DNS Made Easy, Netriplex and Dynect.
After reading up on some blogs 1 & 2 mainly, we setup a Pingdom test to evaluate our three candidates.
For DME I used their own site URL for testing, Netriplex and Dynect gave us dedicated test accounts.
The average response times roughly follow the prices, DME is slowest, Netriplex next and Dynect is the winner. I have detailed logs in anyone is interested (in CSV).
Now for the unexpected results. All 3 providers give very long response times a few times a day - sometimes as long as 5 or 10 seconds. Now and again we see a timeout - i.e. a response of over 15 seconds.
We cross checked by running a testing our current non-anycast Rackspace DNS - similar outliers are present too.
Pingdom tech support think these outliers could be due to peering issues on the internet.
I would expect anycast DNS to be much more robust and to give decent response times even if there are localised networking issues.
So our outliers are either down to the way Pingdom does the testing, or just a 'feature' of the way DNS works.
Anyone with any bright ideas on how to explain this?
I've been fiddling with Plesk to get HTTPS to work for [URL] .... Unfortunately I haven't had any successes at forcing HTTPS, all result in a 'to many redirects' message.
The certificate is already activated and can be verified trough; [URL] ....
All my sites on both my hosting accounts are infected with an iframe.
At the end of the index.html files the malicious code just appeared...suddenly 3 weeks ago.
The host blamed Joomla so I took the appropriate steps:
Upgraded my Joomla to the latest version, changed the whole account username and password, changed the configuration and template to unwriteable.
It stopped the injection for a few days but then it came back. I would also like to add that 2 other sites on my account, one simple index.html file and an old website I have that is totally HTML with nothing to do with Joomla also got infected.
The iframe also infected a Drupal install I did as a test.
So according to these fact is this a Hosting Company not taking responsibility or can a Joomla site infected spread to other normal HTML sites and different CMS's on the server?
This situation is ruinning me and I strongly suspect it's a Hosting problem and not Joomla.
Any expert opinions from true professionals would be appreciated because if I can prove that it's not a Joomla issue I might take legal action against the hosting company since this has cost me dozens of hours of work and several hundred dollars of lost revenue.
I am attaching the iframe exploit. It installs itself on every index file...in every folder - components, mambots, ect..additionally it attaches itself on any and every kind of addon that has an index.html file.
