urpad.net - review


I bought 2 VPS from them couple of weeks ago. One in Seattle and one in Dallas-Texas. I was planning to go for a 3rd one in New York, but I canceled that idea. For both I used a special promo code found on the internet, that offered me 1GB of RAM, 500GB bandwidth and 40GB of disk space for 5,99$/month.

One thing that I love about them (still do) is that their sales & support are online, like all the time. I tried weekend, day/night, etc. So one huge point for this one.

Couple of hours after I opened the account with them, I noticed that my Dallas VPS was performing very very slow... so I've opened a support ticket with them. The replies were coming in couple of minutes, less than 10 usually. One of the technicians answer contained the server load and I want to share it with you:

===================================
# uptime
06:28:25 up 65 days, 6:31, 1 user, load average: 10.46, 10.70, 10.20
===================================

This load seemed exaggerated for me, so I asked for a refund for this server.

The sales guys, answered at the refund request in ~12 hours, very politely they offered me to move my VPS to a different server with lower load, so I accepted:

========================================
Uptime / Load:
18:03:43 up 74 days, 15:51, 1 user, load average: 0.89, 1.16, 1.11
========================================

Everything was fine after that with both VPS, until Seattle VPS was rebooted without any notice. The response from the tech was:

========================================
We have rebooted the host node after performing some optimization and Os upgrades.

Due to this all the VPS servers resides on the server has been rebooted.
========================================

I can't accept this, plus the VPS was bought for testing purposes only, so I asked for a refund. The response from the sales guy was:

========================================
Thanks for writing in. Per URPad.net's terms of service you agreed prior signing up for our services ( http://www.urpad.net/terms-of-service.shtml ), we do not offer any refunds on our VPS Hosting services.
========================================

It seems that they do offer 30 days money back, but only for web hosting (as advertised on their main page), not for VPS. I am calling this a "lie by omission", but maybe I'm wrong because I didn't read the full TOS.

Now some technical details...

Test IPs:
Dallas: 63.143.40.137
Seattle: 63.223.113.18

Disk Speed
Dallas:
root@dallas:/var/www# dd if=/dev/zero of=./test.file count=1M bs=1024
1048576+0 records in
1048576+0 records out
1073741824 bytes (1.1 GB) copied, 7.27147 s, 148 MB/s

Seattle:
root@seattle:/var/www# dd if=/dev/zero of=./test.file bs=1M count=1024
1024+0 records in
1024+0 records out
1073741824 bytes (1.1 GB) copied, 7.59839 s, 141 MB

Result:
Disk speeds are great for a VPS.

Memory test
Dallas:
root@dallas:/mnt# dd if=/dev/zero of=./test.file bs=1M count=1490
dd: writing `./test.file': No space left on device
1022+0 records in
1021+0 records out
1071116288 bytes (1.1 GB) copied, 0.445975 s, 2.4 GB/s

Seattle:
root@seattle:/mnt# dd if=/dev/zero of=./test.file bs=1M count=1490
dd: writing `./test.file': No space left on device
1022+0 records in
1021+0 records out
1071120384 bytes (1.1 GB) copied, 1.26588 s, 846 MB/s

Results:
Even if my RAM is burstable to 1,5GB, it seems that I can't use more than 1,1GB. This test was done with a tmpfs. Also, the Seattle one seems to be very slow for some reasons, maybe a little swap usage?

CPU test
Dallas:
4x Intel(R) Xeon(R) CPU E31230 @ 3.20GHz
I was able to do "cat /dev/zero | gzip > ./testX.file" for 4 times with a 400% CPU usage (4 cores), without any iowa or st.

Seattle:
4x Intel(R) Xeon(R) CPU E5405  @ 2.00GHz
I was able to do "cat /dev/zero | gzip > ./testX.file" for 4 times with a 400% CPU usage (4 cores), without any iowa or st.

Results:
CPU is not oversold.

Download test file
Dallas:

Seattle:

The VPS will be online until the end of April 2012 if somebody require some special testing on them, let me know and i'll gladly do it.

nf_conntrack: table full, dropping packet.

I was getting a lot of errors like this one in dmesg and /var/log/syslog:
nf_conntrack: table full, dropping packet.
It seems that the easy fix was to increase the /proc/sys/net/netfilter/nf_conntrack_max from 31928, in my case, to 65536. In order to do that, I used these commands on live system:
sysctl -w net.netfilter.nf_conntrack_max=65536
To have them after the reboot, I added in /etc/sysctl.conf the following line:
net.netfilter.nf_conntrack_max=65536

Apache: Invalid command 'RewriteEngine', perhaps misspelled or defined by a module not included in the server configuration

I was playing with Apache 2.2 lately and I got the following error when using .htaccess:
Invalid command 'RewriteEngine', perhaps misspelled or defined by a module not included in the server configuration
It seems that the rewrite module was not activated. In order to activate it, I used:
# a2enmod rewrite
Enabling module rewrite.
Run '/etc/init.d/apache2 restart' to activate new configuration!

Office 2010 Home and Business trial - 64 bit - download link

I was searching for couple of days for the Office 2010 Home and Business trial - 64 bit version, but only the 32bit seems to be available.
All the forums and blogs are mentioning to get the 32 bit and use the setup of the 64bit, but that setup is not present (on the DVD it is).

So here it is the download link to 64bit version of Office 2010 - Home and Business:

OFFICE 2010 Home and Business TRIAL - 64bit DOWNLOAD LINK

Please post a comment if the link is not working and I'll try to get another one. It has 1.1GB not 942MB like the 32bit version.
