To enable directory browsing and downloading in Apache, what you only need to do is enable directory browsing and make sure that the file has read access. But in IIS, you have to do an extra task, which is to identify which file extensions are allowed.
To enable file downloads, go to IIS Management Console. Look into folder properties -> HTTP Headers. Click on MIME Types and enter the file extension you want to allow.
On your server:
1. Just create an SSH account.
On your client (Linux/Mac):
1. Open a terminal and key in the following,
#ssh -fND 8080 username@remoteserver.net
2. Open Firefox and go to Preferences -> Advanced -> Network -> Proxy Settings and choose “Manual proxy configuration.”
3. Put “127.0.0.1″ for the SOCKS host field and “8080″ on the corresponding port field.
4. You can now start browsing.
Optional:
5. If you want to use the DNS server of the SSH server, open Firefox and key in “about:config” at the address bar.
6. Look for “network.proxy.socks_remote_dns.” Double-click it to change the value from “false” to “true”.
7. You can now start browsing!
Execute the following:
sysctl -w net.ipv4.icmp_echo_ignore_broadcasts=1
sysctl -w net.ipv4.conf.all.accept_redirects=0
sysctl -w net.ipv6.conf.all.accept_redirects=0
sysctl -w net.ipv4.conf.all.send_redirects=0
sysctl -w net.ipv6.conf.all.send_redirects=0
sysctl -w net.ipv4.conf.all.accept_source_route=0
sysctl -w net.ipv4.conf.all.forwarding=0
sysctl -w net.ipv4.conf.all.rp_filter=1
sysctl -w net.ipv4.tcp_max_syn_backlog=1280
sysctl -w net.ipv4.tcp_syncookies=1
sysctl -w net.ipv4.conf.all.log_martians=1
sysctl -w net.ipv4.conf.all.mc_forwarding=0
To make it permanent, put the same line above minus the “sysctl -w ” command in /etc/sysctl.conf
net.ipv4.icmp_echo_ignore_broadcasts=1
net.ipv4.conf.all.accept_source_route=0
net.ipv4.conf.all.mc_forwarding=0
net.ipv4.conf.all.rp_filter=1
net.ipv4.tcp_max_syn_backlog=1280
net.ipv4.tcp_syncookies=1
net.ipv4.conf.all.accept_redirects=0
net.ipv6.conf.all.accept_redirects=0
net.ipv4.conf.all.send_redirects=0
#netstat -an|awk ‘/tcp/ {print $6}’|sort| uniq -c
#netstat -anp
#lsof|grep LISTEN
1. Show active connections using netstat:
>netstat -anb
2. Kill connection based on process ID.
>taskkill /pid <pid>
Last year, I was fortunate enough to have participated in two international workshops. One was entitled,” eLDI – eLearning
Development and Implementation,” sponsored by the Federal Ministry for Economic Cooperation and Development (BMZ) on behalf of the Government of the Federal Republic of Germany, implemented and supported by common sense through Inwent. The other was, “IOSN-INWENT LINUX TRAINING OF TRAINERS (LToT),” presented by the ASEAN+3 Node of the International Open Source Network and Inwent Capacity Building International, Germany in cooperation with the Information Technology Center of the National University of Laos.
The eLDI workshop started from May 24, 2008 until February 6, 2009 with a total of 300 hours, which includes 100 hours face to face and 200 hours online. The program consists of the following basic modules: Instructional Design, Content Development, Interactivitym eLearning Technology, eLearning Management, Tutoring and Support of Virtual Learning Communities. Both face to face workshops were held in the UPOU campus, in Laguna, Philippines.
The LtoT workshop was held at the Information Techonology Center of the National University of Laos in Vientiane Capital, Lao PDR from the 8th to the 19th of September 2008. The workshop was for preapringparticipants for the Linux Professional Institute Certification Level 1 (LPIC-1). The first week covered topics on LPI 101 which are the following: Hardware and Architecture; Linux Installation and Package Management; GNU and Unix Commands; Devices; Linux Filesystems; Filesystem Hierarchy Standard; and The X Window System. The second week covered topics on LPI 102 which are the following: Kernel; Boot, Initialization, Shutdown and Runlevels; Printing; Documentation; Shells, Scripting, Programming and Compiling; Administrative Tasks; Networking Fundamentals; Networking Services; and Security.
With the knowledge and skills I have gained from both seminars, I was able to incorporate LPI topics with my courses in a blended learning approach. Recently, I also conducted a workshop on distance learningand will hold another one this April 2009 followed by another on LPI and open source solutions. Since I got certified with LPIC-1, there
has been a steady demand from our students and faculty for me to hold seminars on Linux and FOSS.
Now, I’m busier and happier than ever!
