How to Share a Wireless Connection via Ethernet Using Squid on Ubuntu

Filed under: Status — Darran at 12:35 pm on Sunday, August 15, 2010

I needed to share my wireless internet connection on my laptop to a few computers that did not have wireless network cards. This is how I solved the problem.

What you will need:

1. Computer with wireless internet connection running Squid on Ubuntu

2. A few ethernet cables

3. A switch

4. A computer to share the connection to

Instructions:

1. To begin make sure your squid proxy is up and running on the computer that has the wireless connection. To do this open a web browser configure your browser to use your squid proxy (located under network settings on most browsers). The host will be localhost and the default port is 3128. If you don’t have squid installed  use “sudo apt-get install squid” to install squid on Ubuntu. Below is a screenshot of what the settings will look like using Google Chrome as the web browser. Once you have configured your browser visit a webpage and make sure it is working by making sure webpages load correctly.

2. ow you need to configure your wired ethernet card on your machine. Only one setting needs to be modified. Go to network connections in Ubuntu by either right-clicking the network icon in the gnome panel and clicking Edit Connections or going to System->Preferences->Network Connections on the Ubuntu menu. Locate your wired NIC and click edit. Go to the IPv4 Settings tab and click the “Routes…” button in the bottom right corner of the box. On the next box that opens check the box that says “Use this connection only for resources on its network”. The reason we are checking this box is so that Ubuntu will know to use your wireless connection for the internet and not your wired/ethernet connection. Click OK. and Apply to have the new settings take effect. NOTE: If the connection is currently in use the settings might not take.  To fix this unplug your ethernet network card before making the changes.

3. Connect your wired/ethernet adapter to the switch.

4. Connect the computers you want to share your connection with to the switch.

5. To tell the computers without internet to use your computer with internet you need to set them up to use the squid proxy as their internet connection.

6. To do this Ubuntu go to System->Preferences->Network Proxy on the Ubuntu Menu.

7. Select Manual Proxy Configuration and fill in the IP address of the wired network adapter of the computer with the wireless internet connection. In this case the IP address is 192.168.0.100. Now you should be able to browse the internet on the computer you just connected to the switch!

Troubleshooting:

1. Make sure you can ping the computer hosting the internet connection.

2. Make sure you can access port 3128 on the computer hosting the internet connection. System->Administration->Network Tools->Port Scan

3. Make sure your squid configuration access list includes the IP’s of the computers you just connected. /etc/squid/squid.conf – Note: SQUID needs a restart for access list changes to take effect.

Possible access list configuration:

# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed
acl localnet src 10.0.0.0/8 # RFC1918 possible internal network
acl localnet src 172.16.0.0/12 # RFC1918 possible internal network
acl localnet src 192.168.0.0/16 # RFC1918 possible internal network

4. Make sure when you connected your wired network adapter to the switch your internet did not break. If this is the case you most likely have a problem with Step 2!

I am quite ashamed for not posting something in quite a long time. Posting has become more sporadic with full time employment. Looking to get something across soon.

Breakfast with Danny and Vincent, Walk in Botanical Gardens, Grocery Shopping, Explored Christchurch, Big Night Out – Christchurch, New Zealand (Day 27)

Filed under: Status — Darran at 1:34 pm on Monday, May 31, 2010

Today started out with Vincent, Danny, and I scouting out some food. We ended up settling on Subway for breakfast. After that we split up and I ended up  taking a stroll around Christchurch. During the journey, I visited the Christchurch Botanical Gardens. The gardens are very pleasant and have a good variety of plants to check out and are a good place to do people watching. Christchurch has a main square called Cathedral Square in the center of the city. This is a great place to chill and on the weekends street performers and food vendors can be found in the square. The most identifying feature of the square is the cathedral that sits in the corner of it.

After visiting the gardens and walking around other parts of Christchurch, I visited a few bike shops, a computer store to buy CD’s to back up pictures, and a Pak’n Save to pick up some fruit, juice, and other items. I think I then grabbed some more food and visited an internet cafe to upload some pictures to Facebook. Eventually, we all ended up back at the hostel. I think we started out at the hostel bar playing some Uno and chatting before then going out to a bar called Shooters. The place started off dead, but was quickly filled with college kids. At Shooters the drinks are expensive, the music is decent, and the crowd is sort of rowdy, but in general this place is just whacky. The bouncers are retarded and eventually half our party got kicked out. Lucy got kicked out for falling asleep on the bar, Vincent got kicked out for supposedly dancing with a prostitute, and I got kicked out for looking too tired. I think we got bounced because we were backpackers and they didn’t want to have anything to do with us. Three out of our party of six got kicked out and soon the rest of our group would follow. We then ended up in an Irish pub with some live music which promptly shut down.

After making a disjointed journey through town we ended up McDonald’s. Here we proceeded to have a late night feed. At that time McDonald’s was running a combo called the Mac Attack. This bad boy is 2 Big Mac’s, fries, and a drink for around 10 NZD. It was exactly what I needed and I promptly destroyed it before we ended up heading back to the hostel and crashing.

Long Day on Bus to Christchurch, Stops for Lunch and Lookouts, Indian Food with Vincent, Quiet Night at Saints and Sinners Bar – Christchurch, New Zealand (Day 26)

Filed under: Status — Darran at 9:01 pm on Sunday, May 9, 2010

Even though we took it relatively easy the last night in Queenstown, the morning after still felt like we had a big night. Maybe it was because we had a big night, maybe it was because three weeks on the road was really starting to take its toll. The bus out of Queenstown had about 15 people on it. By the level of activity on the bus you would think no one was on it. Most everyone ends up destroyed mentally, physically, and financially after their adventures in that blessed place. The good news was that not long into our journey we stopped in a junction town called Cromwell. If you end up here make sure to check out the bakery. They make mean meat pies and sandwiches.

It was a long day on the bus and eventually we stopped at Lake Tekapo to eat lunch. Vincent and I spent the stop throwing the rugby ball around and enjoying the weather and the scenery. We also visited The Church of the Good Shepherd. This would be a magnificent place for an intimate wedding.

Finally, we got in to Christchurch, checked in, took a shower, and met up with our new roommates. We also caught up with Mark who had left Queenstown the day before and had already made some friends. Around dinner time Vincent and I went out exploring and settled for a mall food court. Then we headed back to the hostel bar, Saints and Sinners, and ended up having a mad session of UNO. The trip seemed to be morphing from intense madness to a more mellow vibe.
