Hi everybody!

Hope this is the right forum for this question. I always had a problem with connecting to some sites like hotmail and msn -which I think is the reason why kmess cannot also connect to its server. Some other sites that require authentication, like my university's email account, cannot be accessed. It's not Firefox's fault since it works perfectly in my Windows partition. I encountered the same problem even when used openSUSE10.2 , the download bar stacks at a particular point. I also don't think the cause is the internet connection because all the previously mentioned sites worked for some intervals, like a week or so, and then stopped again. If I were using Windows I would check the Firewall and internet security settings, but in KUbuntu7.10 things are much different.
If anybody had the same problem in the past please send some advice.

cheers,
Thomas

Post the contents of your firewall by typing this as root in the command line (konsole):
iptables -L

How are you connected, how is the box connected to the internet, directly or used through a hub, switch or router?
Are you using a static ip or relying on DHCP to provide you with a dynamic ip?

Check your /etc/hosts.allow and /etc/hosts.deny files to see if those server names or ip's have been put in there

Are your DNS servers setup correctly (assuming you use a static ip)

I've moved this to Networking, as it's not a security issue.

Thank you for your reply.

The contents of my firewall are:
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

Right now I'm connecting to the internet by the university's network but a few months ago -I had the same problem again- used ADSL from home and a small router(http://www.thomson-broadband.co.uk/p...?ProductID=532) .
As for the question about static ip or DHCP, at my system settings->networks->intervener(my system's language is Greek so I am not sure if this is the equivalent english word) I have the option "connect directly to the internet" activated. If this doesn't cover your question, could you be more precise about how I am going to find out if I am using static ip or DHCP. My distribution is Kubuntu7.10.
Finally the files /etc/hosts.allow and /etc/hosts.deny contain only information about some commands (e.g. hosts_access, hosts_options, etc), no actual server names. Did you mean that I have to use these commands to get the answer or just check the contents of the files?
I am sorry if I've been tiresome, is just that I don't have much experience on networks.
Thanks again,
Thomas

in a konsole type:

ps aux |grep dhcpd

if this returns nothing, it means it's not running.

can you ping the actualy server you are trying to contact?
do a DNS lookup of the server for example in konsole

whois www.google.com
to make sure the ip is real
traceroute <ipaddress>

now that yopu have this information ping the ip and see if your icmp requests make it there, if they do then you should have no problems connecting to them, it is on there end and you should contact there tech support.

Dear proc, whatever,
ps aux |grep dhcpd returns the following line:
thomas 8619 0.0 0.1 2988 776 pts/0 S+ 18:59 0:00 grep dhcpd

whois www.google.com didn't work, it just returns the usage details of whois command, so I typed more /etc/resolv.conf instead and got:

search sns.york.ac.uk
nameserver 144.32.128.228
nameserver 144.32.129.66

traceroute 144.32.128.228 gives:

traceroute to 144.32.128.228 (144.32.128.228), 30 hops max, 40 byte packets
1 host-172-16-8-10.sns.york.ac.uk (172.16.8.10) 1.795 ms 1.831 ms 1.912 ms
2 * * *
3 * * *
....
30 * * *

As I expected traceroute 144.32.129.66 gives also the same but with some slight differences in times.
ping returns:
--- 144.32.128.228 ping statistics ---
30 packets transmitted, 30 received, 0% packet loss, time 28999ms
rtt min/avg/max/mdev = 0.372/8.259/234.937/42.093 ms

I don't think the problem is the DNS since as I said in my previous message these webpages couldn't be opened even when I used another DNS at home. It seems to be more like bad internet settings. Any other suggestions?

And you say this works perfectly in windows though?

__________

Exactly.

I am at a stand still... there must be something I am not thinking of.. what happens if you set your browser's id to Firefox on windows?

Is SSL installed?

Yes it is.

Didi you try changing the user agent under Linux to windows/firefox to try to fool it?
