comment Can't allow users to log in via SSH (Bash, OpenSSH, CentOS 6.5)
If you have a Linux client, what happens if you turn on verbose logging (-v). Similarly, are you in a position to run sshd in the foreground with logging ? Lastly, did you restart SSH after modifying AllowUsers ?

comment Traceroute to my IP address is slow while ping is fast
It could be failing DNS lookups. Its probably also related to routing - possibly a firewall blocking certain types of ICMP traffic (as implied by the "Tracerouter also shows no hops to my IP address" bit)

This does not belong on serverfault - maybe Superuser ? (Flagged for moderator attention)

comment link aggregation with wifi and ethernet on Linux
are you sure - I don't see a compelling reason that this wouldn't work under some modes - particularly as most AP's/routers bridge the WLAN and ETH interfaces anyway [ at least when using **WRT], and AFAIK there is no egress filtering getting in the way either. IE I don't see from a "network packet" perspective WLAN is treated any differently to ETH interfaces on these devices.

comment How to manage multiple printers?
Radical thought (thus not an answer as it doesnt qualify), but what about ensuring your printers are all IP enabled and support a minimum standard - for example PCL6 - and then simply configure all the desktops to use a generic PCL6 driver. this might cost you in some bells and whistles (like double sided printing), but will removes the driver handling issue.

comment Automatically add rules to iptables when an user logs in or logs out with ssh?
Depending on the timeframe (is a second or so OK ?) you may be able to use fail2ban - Fail2Ban reads a given logfile as its write and takes actions you configure it to do (including adding iptables rules if you desire).

comment Injecting Response Headers based on logic in apache
I'm not an expert here, but have you looked to use mod_security and a script to intercept and inject the header in conjunction with Apache ?

comment Webhost similar to Dropbox with PHP Support?
This is probably a better fit for serverfault. Maybe you are asking the wrong question and might be better off asking "How can I get dropbox like functionality" on a web provider. There are a number of avenues worth exploring including "Homecloud" and Using an SSHFS or FTP fS (where the files appear on your computer as a shared drive, but the sharing is done using the ssh or ftp protocol).

comment Unable to mount '/dev/sda'
I think the answer is correct (so upvoted), but the wording is I feel a bit harsh (particularly as there are rare instances where you would mount /dev/sda) and arguably misleading. Although it is wrong to do mount /dev/sda /mnt here it simply won't work - it will not harm the disk or screw anything up.
