system failure: POST failed, status=413 upload too large: file '/': upload too large -- Restoring Large Zimbra backups

Okay so zimbra account restoration for large accounts ( above 1GB ) was not working for me. the following steps helped to restore large accounts.

What you need to do is  to change parameter rest_request_max_upload_size to a larger value. Here we will change it to 10GB.

# su zimbra
# /opt/zimbra/bin/zmlocalconfig -e rest_request_max_upload_size=10737418240
#  zmmailboxdctl restart
# exit

Then run the import backup account like this as root user.

# /opt/zimbra/bin/zmmailbox -z -m "email@domain.com" postRestURL "//?fmt=tgz&resolve=reset"  backupfile.tar.gz

Thanks to Andrea for the tip :)

Ruby installation issue with openssl

So i was trying to install ruby 1.87 and the compilation broke due to openssl issue. The error was something like this.

ossl_pkey_ec.c: In function ‘ossl_ec_group_initialize’:
ossl_pkey_ec.c:761: warning: assignment makes pointer from integer without a cast
ossl_pkey_ec.c:815: error: ‘EC_GROUP_new_curve_GF2m’ undeclared (first use in this function)
ossl_pkey_ec.c:815: error: (Each undeclared identifier is reported only once
ossl_pkey_ec.c:815: error: for each function it appears in.)
make[1]: *** [ossl_pkey_ec.o] Error 1
make[1]: Leaving directory `/usr/local/src/ruby-enterprise-1.8.7-2012.02/source/ext/openssl'
make: *** [all] Error 1

So applied this patch to the openssl file in the extracted ruby source and finally the compilation was successfull. You will need to specify the location of the ossl_pkey.ec.c file in the below file or you can mention it while patching.

Change your location to the ruby source directory and save the contents to a file named patch.txt. then issue the following command to patch.

#patch < patch.txt

Hope this helps :)

For those who have Issues running Microsoft Office 2007 on Wine.

So I had to remove my windows altogether and run linux. I choose the latest stable release of Mint 17, i need to have ms office installed and figured out the wine package should handle this fine. however it was not smooth as i thought.

Installation was fine. But the excel and power point was not opening and had trouble. So here is something that I did made it work for me.

1. Open the wine configuration ( gui --> Configure Wine ) and select the windows version to be "windows xp"

2. Check the libraries tab next, you will need to add  a new override for the library, choose "riched 20" and click add. Then you need to edit this newly added override and change the load order to "native ( windows )" 

 
 Apply the wine configuration and then try launching the powerpoint or excel, it should work :)
