internet connection issues


I am new to bsd, I used sysinstall to configure my network device, vr0 (via rhine) I used dhcp at first, that worked fine, but I needed to manually specify the address, I entered the hostname I wanted (thebes) and the domain name XXXX.net (not the real one). then ip4 gateway 192.168.0.1 (my router) ip4 address 192.168.0.4, netmask 255.255.255.0, no extar parameters. I told it to go ahead and bring up the interface.

now then before stating the problem I will state what I have tried, I have tried rebooting, tried reconfiguring, tried different combo's, tried to manually configure the interface with ifconfig and route.

now I can ping the router (192.168.0.1), and I can ping other comps on the lan, I can also ping google, I do ping www.google.com and it replies.

problem:
gaim, mozilla, firefox, etc. nothing can actually access a website beyond resolving it and pinging it.

correction, it works, but it takes forever, I type in the website and about 3-4 min later it comes up. The other day I had similar issues but it was ssh taking about 4 min to connect, I corrected it by disabling an option in the config.

Let me guess ... DSL?

Google for DSL and MTU size

Did you take a look at the /etc/rc.conf file to make sure there are no conflicting entries since you have configured wtih sysinstall more then once?? I had issues before when I had more then one configuration in that file before

Not to step on your toes here, but ... would you care to qualify that statement?

There is absolutely no situation that I can think of that sysinstall (or really any other piece of software, BSD or not) could produce that would allow you to ping hosts both on and off your subnet but not be able to move big packets to them, short of the MTU size being too large.

what does that have to do with my statement?? I said that if you have conflicting entries things can get screwed up so you should look at the file becuase I have seen sysinstall keep adding entries you put in over top of each other and then things get screwy.

I assumed that your statement was intended to provide some potential insight or assistance to the OP's question/problem. Apparently, that was not the case.

The fact that you ask what my question has to do with your statement implies that trying to explain why I asked would only irritate both of us.

Question withdrawn.

I wasn't trying to "controdict" everything you say. In fact, I find that offensive coming from a person who post in nearly every thread I have in the last week with either a "me too" post, or something that isn't likely to help the OP at all. Take this thread for example, and my question to you that seems to have upset you to some much greater extent than I ever intended.

Your post made the assertion that it would be possible for sysinstall to hose up rc.conf to the point that the machine would behave as exodist's is. I asked for clarification on that, as that's just not possible. Even if sysinstall writes the same variable to rc.conf 50 times with different values, it doesn't matter at all. Only the last one's value will be used. I suppose you could have the gateway set to one subnet and the IP set to another subnet or something stupid like that, but even that wouldn't cause the OP's problems.

With a basic understanding of how networks and TCP/IP work, it kinda sticks out that this isn't a DNS problem, or a routing problem or (most likely) a firewall problem. Most likely it's the same problem that lots of people have with the MTU on DSL (or other PPPoE systems). I'd go into more detail, but I'm sure that you've already heard about it somewhere between your CISSP and your CEH (What's CEH? Certified Ethical Hacker?)

So, if you want to think me a jackass for asking what you were talking about, go right ahead. You're certainly not the first, and I doubt you'll be the last.

To drag this thread kicking and screaming back toward the OP's question ...

Exodist:

It really sounds like you're falling victim to transmission issues. I'm working on the assumption that you have DSL, but any PPPoE situation can suffer from this. Check out the following:

Here's Cisco's take on it. The section on "Why the MTU Size Must Be Changed" will likely prove useful.

There's also a decent post on monkey.org about it, as well as this page.

Also, Via chipsets suck. It's possible that the NIC just doesn't work right. Do you dual boot this machine, and if so, does everything work in the other OS? I had a vr nic once that would only run ~3MB/sec on the lan. Swapped it with a xl and *bang* 12MB/sec

Also, you should check the media type and duplex on your nic with ifconfig. You'll want 100baseTX (full-duplex) most likely.

Hopefully something in there will help.

thanx for the information... and entertaining argument as well :-D... the board works fine in other os's. I do nto have time to test your suggestions at the moment, but I will soon, thank you, yes I do use dsl, the bsd box specifically goes through a standard netgear router I have connected to my dsl router that provides 5 static ip's, (I have more than 5 comps, so 4 are connected to static, router to the 5'th static, then other systems that don't need static ip's to that second router.)
