== Step 1: your login == Most people log into a vserver using ssh as an administrator. Ssh uses pam. And pam sets your *hard* limit. The default usually is 1024. Well, that's not a problem on normal systems, because once you gain root, you gain the right to ruin everything. This time you won't. The ceiling is set by pam, and you cannot raise it anymore. Whatever you do now, you won't be able to raise it. So we need to set that: in your vserver the pam limits configuration must be set for whatever you login to. On a debian system you should probably have a line like this in /etc/security/limits.conf: @staff hard nofile 32768 This means that everyone in the administrator group staff gets a hard limit of 32768 when logging in or doing whatever. You can check that with: ulimit -Hn
