Number Of Hops In Traceroute

Nov 4, 2008

If I'm doing a traceroute on two IP addresses (different networks).

The one with the less hops means it's the fastest network from where I'm from? Right?

And is it (less number of hops) more important than lower ping time?

Less Hops Or Less Response Time

May 28, 2008

We are thinking to get Level(3) into our mix in Seattle datacenter. We did some tests from the UK, and the result is: Level(3) network can give less response time (from 3-10ms less), but run through more hops (4-6 hops more)

So, question is

- for normal hosting, which way do you prefer? Less hops or less response time?

- for VoIP service, which way do you prefer? Less hops or less response time?

Virtual Private Server (VPS) Unlimited Number Of Website With Unlimited Number Of Domains?

Oct 5, 2007

I'm new to Private Virtual Server and the package offered by different company are quite confusing.

I was on RackForce and their basis VPS package dds200-L can host 100 domain names on Plesk and unlimited domain names on WHM/Cpanel.

On 1and1 it didn't say if Plesk support 100 or unlimited domain names. My question is, do we always have the liberty to host unlimited domain names on our PVS?

Can anyone recommend a good VPS hosting company?

Traceroute :: TTL Exceeded

Jun 21, 2007

My server has been accessible in and out all day.

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....

Understanding Traceroute?

Dec 31, 2006

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....

Leary With Traceroute Results

Dec 13, 2007

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 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 to their outer router. Should it be a concern that we route through everyone through a IP?

Ping And Traceroute Executables

Aug 13, 2008

I installed net query tool from this site

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 or any other network tool site.

What is the location of those executables?

Understanding Ping/traceroute Times?

Aug 3, 2007

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):

PING ( 56(84) bytes of data.
64 bytes from icmp_seq=1 ttl=56 time=1.26 ms
64 bytes from icmp_seq=2 ttl=56 time=1.35 ms
64 bytes from icmp_seq=3 ttl=56 time=1.41 ms
64 bytes from icmp_seq=4 ttl=56 time=1.22 ms
64 bytes from icmp_seq=5 ttl=56 time=1.51 ms .............

Simple Network Monitor - PING / TRACEROUTE?

Oct 5, 2006

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.

Shared Hosting With Shell, Cron And Ping/traceroute

Jan 10, 2009

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?

Number Of Sites

Aug 28, 2008

I just want a rough idea; How many sites could safely fit on a server with the following specs?

CentOS Linux 5.X

I am thinking in terms of CPU power and Ram here. The sites I have in mind are all low usage (at most 300MB storage and 1GB bandwidth per month) so bandwidth and storage is irrelevant here.

Ban A Large Number Of IPs

May 30, 2007

I'm currently using iptables to ban IP addresses from the servers, like:

iptables -A INPUT -s -j DROP
I ran a "spam trap" for the last few months and now I have over 11000 IP addresses who were trying to spam on my website (guestbooks, phpBB and forms) and I want to ban them all (pretty sure bots run from them).

My question - is iptables the way to do it? I mean does banning such a large number of addresses have any significant performance or other issues I should be aware of (except of the fact I may be banning some legitimate traffic)? Is the -A INPUT the way to ban them all or is there a more appropriate way of baning such a number of addresses?

I'm on CentOS 4.5 i686, Apache/1.3.37, Pentium D 930, 2GB RAM.

Can we use the same AS number in both datacenters?

We use default BGP routes in a active/passive configuration. I would like to speak with someone who has knowledge of BGP, AS. happy to pay for a consultant if needed. want to make sure we set this up right.

Increased Number Of Host

Apr 26, 2008

Is it me or are a ton of hosts having problems right now?

Many have closed up and/or disappeared and/or are having substantial downtime. To name a few right now: RisingWebWorks and BionHosting.

Do you guys think it's in part due to the US economy? Or is it just poor management?

It seems to happen in spurts as well. It's quiet for a while, then all at once a bunch of them have problems.

Just my two cents.

What's The Maximum Number Of Rules For Iptables?

Jul 19, 2008

I use APF and APF is working with iptables , when I define a large number of IPs in deny_hosts.rules or allow_hosts.rules and restart the APF , iptables begins to display errors after applying some number of rules , I have set SET_TRIM="0" in APF , so the number of APF rules is unlimited and the error is from iptables.

Is there any setting in iptables config files for maximum number of rules?

Is it unlimited and depends only on system available memory? O/S , ...?
