I have an ec2 instance with an older version (3.0.2) of R that I'm trying to update to the latest (3.1.1). This is not available in the default yum repo, but is available under EPEL.

The installed version is 3.0.2:

These are the repos

Specifying the epel repo, I can see version 3.1.1, it is also listed here

However when I try to install using sudo yum --disablerepo="*" --enablerepo="epel" install R-core I get the following errors:

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Presumably this is caused by disabling * repo and only enabling epel which could prevent some dependencies being found, I had to do otherwise it'd only find 3.0.2 from amzn_main.

What is the correct command I should use to install 3.1.1 from the epel repo?

I have my main domain URL mapped to the root of my server

I have a wordpress installation installed under /blogs/techblog

I want to direct any traffic coming in at jameselsey.co.uk to > jameselsey.co.uk/blogs/techblog

If I point the URL itself to the subdirectory then my installation will not work

Is it possible to do this with an .htaccess file in the root of my server?

I have tried the following, but it creates an "endless loop"

Redirect 301 / http://www.jameselsey.co.uk/blogs/techblog/

We have 2 guys claiming they haven't received an email, I have been forwarded the original and the recipient email addresses look OK.

Is there anyway I can check on our exchange server to see the email hasn't been caught out by any (spam) filters? Or any other reason why it would fail on our side?

I have 2 databases setup on a server. I want to import data from DB1 to DB2, using the SSIS wizard (right click DB > Tasks > Import Data)

1. DB1 is the source DB, it has a collation set to Cyrillic_General_CI_AS
2. DB2 is the destiantion DB, it has a collation of SQL_Latin1_General_CP1_CI_AS

I can run through the wizard, using a query of "select * from myTable". That creates the table on my destination DB no problem, I don't save this.

I run the wizard a second time, so I can go into the mappings and select "delete existing rows" (since I can't do this first time round). Then at the end I save it, save it on the SQL server.

I get the following errors :

"MyColumn" cannot be processed because more than one code page (1251 and 1252) are specified for it.
 (SQL Server Import and Export Wizard)

I have checked on MSDN and found this article suggesting that difference in collation types could cause some issues with data type conversions

It was suggested to use nvarchars, so I have started again making sure the table on my destination DB are using nvarchars, but I'm now getting the following error

Data Flow Task: The product level is insufficient for component "Data Conversion 1" (197).

Changing my destination DB collation to cyrillic is not an option, since later on I will be importing from other DBs so may run back into this issue.

Is there anything I can do to work around this issue? I hope I have provided enough info

Thanks

I've got a fedora 12 system, and have installed tomcat6 via yum.

I can start tomcat by issuing: tomcat6 start

I can see this is OK by the catalina.out log file as follows

I have changed the port for tomcat to 8888 as 8080 is in use elsewhere, I have changed this in server.xml as follows

 <Connector port="8888"
            protocol="HTTP/1.1" 
            connectionTimeout="20000" 
            redirectPort="8443" />

I can't get anything on http://localhost:8888 in any browser, I'm thinking that the firewall could have been blocking tomcat. I've disabled the firewall temporarily in system-config-firewall and restarted tomcat, but that doesn't seem to change anything

What else could be stopping access to tomcat? There is nothing in /var/log/messages regarding tomcat other than the yum install logging

I have just installed SQL Server 2005 on a fresh machine, and I'm trying to import 2 databases from one of my servers. This has worked fine for a box that I did this morning but now I'm getting some errors on this second box.

I am doing the following :

1. Right click Database > Restore Database...
2. To database : "myDb"
3. From Device : C:\myDbBkp.bak
4. Check the backup set, and click OK

Normally it would give a popup saying "Import sucessful", but now I get the following :

Restore failed for server "myServer". (Microsoft.SqlServer.Smo)

Additional Information : System.Data.SqlClient.SqlError : Directory lookup for the file "C:\Program Files\Microsoft Sql Server\MSSQL.1\MSSQL\DATA\myDbBkp.mdf" failed with the operating system error 3(error not found) (Microsoft.SqlServer.Smo)

My next questions are :

1. Why is it trying to load an MDF file from a directory I haven't specified
2. Error not found, is that as helpful as it sounds?

Any ideas? I did this successfully earlier on an identical environment with the same versions etc.

Many thanks

I need to alter some settings on Internet Explorer (version 7, but potentially some users may still have version 6).

Doing this manually is fine, change settings, restart IE, done.

However, we have a large amount of users, all of which swap stations on a regular basis, and I'm assuming there is a much more efficient way of doing this than logging into each station as each user.

I'm not a systems admin, but I'd hope there is some command to set IE settings? We could then roll this out automatically.

The settings I need to alter are

1. Add address to trusted sites
2. Enable ActiveX controls (under security tab)

Many thanks
