I am currently employed as an IT security consultant. I frequently code in my spare time and have been deeply involved in computing for as long as I can remember (my earliest memories are navigating my full 4 GB hard drive on Windows 95 and thinking, what is all this junk occupying C:\windows\ and taking up room for all my games? Delete!).

I'd like to share my tips and tricks and anything else I've picked up over the years with the StackExchange community, so I look forward to helping!

comment BBWC: in theory a good idea but has one ever saved your data?
Obviously that was the feature you were aware of. But again, you didn't make that clear. @mfinni is just being helpful.

comment Installing proftpd - dependency issues (libcrypto.so and libssl.so.10)
If you're on StackOverflow with enough points you can link accounts and you'll get 100 points here. Or you could pastebin the answer for me to supply 8-)

yum appears to be in an unclean state, run yum-complete-transaction to let it resolve pending transactions - they might include your dependency packages.

comment Configure iptables over SSH without getting locked out?
Whenever I'm doing risky things that cause connection drop-outs (eg reconfiguring OpenVPN settings), I set a cronjob that will reset to defaults after a period of time. If things go well I cancel the job, if they don't I wait until it sets up access again.

But is there any way around the truncated group names?

comment Setting up VMWare ESXi 5 with a single physical NIC
Indeed. The fact what you're suggesting cannot be achieved without physical access (or KVM I suppose) means that this is not currently feasible in my situation where the server is in another country.

comment Setting up VMWare ESXi 5 with a single physical NIC
I don't have physical access to the server, which is why all I can have is the public IP for the vSphere host that OVH is assigning it on their setup.

comment Setting up VMWare ESXi 5 with a single physical NIC
Hi. My vSphere host is the ESXi server itself, correct? This server is only accessible to me from the Internet so I'm not sure it can practically have an RFC 1918 IP. The VMs themselves I appreciate would. But then how do I actually setup directing a request to connect to the server IP at port x, to a VM?

That's correct @sysadmin1138 - I do only have a single IP address to work with too.

vipw did the job for the user, but I had to change the case in /etc/group too.

comment how to disable SSH login with password for some users?
It's so much stronger it's not in the same ball-park, that was my point. Password authentication should be disabled for root too and keys only allowed for logins.

comment how to disable SSH login with password for some users?
@ceejayoz In the context of SSH, I'd suggest that's what a key-based login is for. Usually root login is unavoidable for admins who don't have physical access to their servers, very common in smaller scale web applications.

comment VMWare hypervisor with only 1 network card?
I am curious as to why they have specified you need two, if it's clearly possible to operate without it... does it involve any trickery with configuration to achieve?

comment Inter-site linking with a WAN cluster infrastructure
Thanks, n2n is interesting but we do not feel it is tested enough for a production solution. We are in a situation to setup a firewall-based VPN tunnel which I think you'll agree is preferable.

comment I just removed a folder in /tmp/ and now apache/mysql is bugged. What just happened?
OVH puts the / on a different partition to /home. You could just move the database files to a new dir on that partition, e.g. /home/mysql. You aren't going to be able to repartition it very easily without KVM.

Why did you just blindly remove a file without thinking what it does? Check your shell history (probably ~/.bash_history

If it really was just a file in the /tmp folder, as long as these services were following the Linux Filesystem Hierarchy Standard, simply restarting these services should resolve any issues...
