I have a problem with one of my domain. Some users around the world cannot access the website, but they can ping and traceroute the server without any problems. I am able to access the website perfectly.
Site URL is www.djluv.in
And we are using IPB 2.2
Moreover if theres another domain on the same server, they can access it.
There are about 25-30 users who are facing this problem, but from different part of the world so I cant even say ISP problem.
APF has been shutdown, no Ban Filters on IPB or cpanel.
What are the possible reasons why they couldn't access the website? how to fix the problem?
I got this domain hosted on my server where i can't ping or trace it. Every setting seem to be correct, the ip address, name server...etc. and other websites hosted on the server is working fine. i can reach other websites with no problem but not this domain.
how do i trouble shoot such problem? would deleted the website and recreate solve it?
A client of mine claimed he had connection issue with our server and send this tracert from his office
<1ms <1ms <1ms XXX.XXX.XXX.XXX (His Internal IP) * * * Request Time Out * * * Request Time Out * * * Request Time Out * * * Request Time Out * * * Request Time Out * * * Request Time Out * * * Request Time Out 39ms 23ms 30ms XXX.XXX.XXX.XXX (Our Server IP)
Is such a route possible in the first place? Our gateway isn't mask.
I've recently moved server and since then I've had a problem with the main site I administrate. The problem is that when I'm moving around the site I frequently get long lag times between clicking on a link and getting to that next page. This isn't slow transfer speeds - the status bar shows 'waiting for xxxx' for sometimes 15 to 20 seconds. The site makes quite heavy use of a MySQL database and associated forum software.
It was suggested I did some tracerts to see what that showed. The thing is I don't know what the significance of tracert results are! It seems to show lots of timeouts - but then it shows lots of timeouts when I try it on other sites as well, which don't have the same lag problems.
I have no reasons to think it's my host, who are really good and responsive. But my ISP says it's nothing to do with them either. If the routing is a problem, where lies the responsibility for selecting the routes between me and the server to my site?
I'm hoping this is just the link between me and my site, as other site users don't seem to have had a problem yet. I'll post a couple of tracert results in case anyone is able to advise me on what their significance might be.
My server DC technician change the cable to another switch in another rack. all in sudden, my server went 'offline'.
the weird thing is, I can ping the server IP
When I plug my KVM, I can ping google.com from my server
But when I lynx google.com, it keep saying HTTP requests sent; waiting for response._
When I open my putty and SSH, it keep waiting.
When I try to ssh from another server, it keep waiting $ ssh email@example.com [nothing happen] $ ping xxx.xxx.xxx.xx PING xxx.xxx.xxx.xx (xxx.xxx.xxx.xx) 56(84) bytes of data. 64 bytes from xxx.xxx.xxx.xx: icmp_seq=1 ttl=63 time=1.10 ms 64 bytes from xxx.xxx.xxx.xx: icmp_seq=2 ttl=63 time=0.864 ms 64 bytes from xxx.xxx.xxx.xx: icmp_seq=3 ttl=63 time=0.854 ms
- I can ping my server from MS DOS - I can ping my server from Iptools.com - I can ping my server from another server
But.. - I cannot ssh into my server - I cannot ssh into my server from another server
Inside my server.. - I can ping google.com, yahoo.com, other servers - But I cannot lynx and open all websites
When I restart network, it shows [refer attachment] captured from my KVM

My sites are up when I go to http and there is no slowdown but my monitors (panopta and pingdom) say that there is an outage in ping (only in ping, http is up). I tried pinging the server and there are packet loss up to 100% but the site is still up. I also used other online pinging tools (all-nettools.com, dnsstuff.com, etc.) and host unreachable.
I tried contacting the provider but they say there are no network problem at this time. So I found this other site that's also hosted on the same provider and I can access their site but fails on ping.
I have 2 CPanel servers. I wanted to transfer multiple accounts via WHM but it gives me error that I cannot SSH into the other server.
I tried to ping the 2nd server from 1st server and it gives me: root@s [~]# ping xxx.xxx.xxx.7 PING xxx.xxx.xxx.7 (xxx.xxx.xxx.7) 56(84) bytes of data. ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted cping: sendmsg: Operation not permitted
I added both server IP into allowed list inside my APF firewall on each server as well.
I rebooted both server earlier before, but it is still not solving my problem.
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.
