I have an old Win XP (SP3) desktop that just recently has a problems with attachments to emails. It simply won't allow me to open or save them.
I have tried both hotmail and btinternet.com (yahoo) emails. When I click on an attachment and choose either 'open' or 'save' the small grey box appears that usually shows the file action and download time info. However no info appears in the grey box and it just sits there (for hours). I have tried the same email attachment on another PC and it works fine so the problem is specific to this PC.
The file size is not a factor, as it fails to open attachments of only 100kb, nor is the file type (pdf). I can download large pdf files from a website with no trouble. the problem is just email attachments.
I tried switching off the Windows firewall, but this made no difference. The a/v is AVG9.0.
I have D-Link's DSL-2730U modem/router. I've enabled the router's firewall and disabled TR-069 (putting in some dummy ACS URL and login credentials as well). However port scans show 30005 as open. I believe this is used by the TR-069 client. How do I definitively filter this port?
I'm new to IT, and have been put in charge of managing our servers hile my boss is on vacation.We currently have a Sonicwall Network Security Appliance that handles our Firewall/VPN and have web content filtering set in place.I have a user who belongs to 2 CFS policy groups that we have set up. I've double checked with Active Directory, and he is a member of both groups.
This person SHOULD have access to Job searches/ and Restaurants,but receives a "content blocked" message on his browser.It appears to me that the settings in Sonicwall are correct, as well with AD member groups.
I am trying to connect to a Security-enabled wireless netowork. I have the key. My problem is that I can't seem to figure out how to enter it. When I try to connect I open the "view available networks"window. I see the network name and it shows a strong signal (all 5 green bars).
We are a non-profit organization that is heavily reliant on interns that use their own laptops a lot here. My concern is they come in and connect to our wireless network with no supervision or anything else. I am worried they will introduce a virus, trojan, or something to our network. What the best way to keep them from introducing unwanted malware from a thumb drive, virus in email, or something to that effect shy of standing over them while they install and run an antivirus software?
I am trying to figure out how to give computers that connect to my LAN limited access. I have heard that some viruses, though rare, may travel through the network and infect all computers on the network. I want to prevent this. Is there any way to give computers connected to my network strict access to only the internet to prevent viruses or any other harmful attacks?
I was wondering how would it be possible for a person to gain access to computer through my router? Or is that even possible? Just a quick rundown, the past few weeks, 2 of my email accounts have been compromised, one was email i had for years, the other was a new random email that i rarely use. In the same week, both these accounts were "hacked" the passwords were changed and i can't get access to them. Same goes for my fb account also compromised. These emails aren't linked to the fb acct neither. I know you might think yeah, i might have clicked on one of these phishing links, but i assure you haven't, i have never entered any of my information on random sites or anything like that. Actually i only really frequent 5 or 6 sites on this certain laptop and i have never downloaded anything on it but songs from iTunes.
I've scanned my computer numerous times, and even went as far as to factory reset it, so i don't know how high the possibility of me having a key logger is.So i guess i'm asking, how would a person be able to have gained access to computer w/o having it in their physical possession? Can i be getting hacked through my wifi connection? What information of mine would someone have to have in order to access my computer and monitor my web activity?
I was trying few days ago a tutorial of SSH tunneling, but I got an error,"server unexpectedly closed network connection", although I did everything like in the video tutorial and port 433 was not closed.
for example, there are 3 sites, A, B and C. A and B are 1.5 km apart and both are separate LAN(mixture of wireless and wired). C is 35 km apart from A and B. I have to connect A, B and C so that they can communicate with each other. Security is required.
Is it true that the FCC is investigating the Pogo game site because of poor security? Is Java the cause of this problem?I'm very leery of getting on the Pogo site because I've been told that my computer could get a virus and crash.
For a few weeks now, I couldn't open any long links on Twitter. I can only open short links which can be highlighted, then right-click and "switch to 'website'". For example, I can open this link, because it's short enough to highlight the whole thing and then rightclick:It opens like that because it directly goes to that website without going through the shortened link first.When there's a long link like this one it won't open, just bring me to a page which says:"Oops, Google Chrome couldn't find t.co"This was mainly on Twitter, but now I found out that none of the shortened links like bit.ly, etc work either.
I just switched to TWC from AT&T and one of my computers running Vista, via wireless, cannot open any inet sites. The browser appears to do its DNS thing, but it sits WAITING for the site then says it can't connect. I have 3 other computers, Vista and W7, and an Xbox that connect OK. IPCONFIG shows valid IP addresses, DNS and gateway. Firewall/AV is off. It connects fine via wire. AND it connects with no security on the router. The router is a Cisco E3000. The laptop is an HP.
i must configure a secured wireless network with access restriction based on SSID. the equipements are : cisco wlc 2504 (soft 7.3) cisco secure acs aplliance 1121 (soft 5.4) . the users that will connect to the network are regrouped by identity groups, each identity group having it's own SSID. Clearly each group of users must access only one SSID. i followed the procedure below to configure it:
-- creating user identity groups;
-- creating users and assigning them to the groups;
--- creating authorization profiles for each SSID under policy element/ authorization and permission/network access/authorization profiles and putting the Airespace-Wlan-Id(the SSID number) in the radius tab.
--- assigning the authorization profiles to the identity groups under access policies.
after all these config the users can access the network using there userid/password configured. But the problem is Every user can access every SSID, seems like the restriction is so not very well configured.
i found some documentation on this kind of config but the version of ACS used seems older than the one that i use, so menu are very different.
I opened my iTunes program today and noticed a roommate's MP3 files were picked up on my network. I think the name of the program is Rocket Tube MP3. Anyway, I came on here because our computers use a Wi-Fi internet connection and I was wondering how much of my web activity (history, cookies, temporary files, etc) he could see from my laptop if his computer was a desktop downstairs. He's very tech-savvy (a former IT guy) and I don't want him snooping through my personal records.
I have problem with the Lan-to-Lan VPN tunnel.the VPN working fines since 9 months ago without any problems.Suddenly got the problem!,In last two days we faced problem the VPN down.in first time the problem in phase-2.. but after that in phase-1... in latest no data packet received to their side.
I am looking for some resources on what steps would be involved in configuring a Cisco ASA 5500 when obtaining a new ISP. Since our static IP will be changing with the new ISP, just need to know what configurations changes will need to take place. We currently have a working config with DSL, but are switching to cable. We are using a DMZ configuration, and are going to try using ASDM first since that should be easier
There are three Win 7 laptops on the LAN trying to connect to the ASA5500 Firewall. They generate a Severity Level 3 alert and try the same port three times then move to the next numerical port and try that three times. Is this a malicious Hack.
I have been trying to get into one website (url)The world's best online marketplace, List free Classifieds,buy and sell - auction,post a job and get hire from over 1 million top professionals. | Wanaifieds.com and I can't get into the site from my home I can get into the site everywhere else but here I called the service provider and their telling me it's not them they don't block website and the IP is not stationary so their nothing wrong with their end I called the hosting company of the website and they told me they don't block any IP's I don't know what to do I do remember when it was working about 4 days ago I tried something o the site and I messed up and I clicked back instead of putting my password a little box poped up and said something about a certificate or something but I just clicked off and when I tried to get back on the site.
I'm working with Cisco ASDM 6.1 for pix. I want some of ip addresses are not shunned thus provide a list of addresses which should not be shunned in threat detection, but some of ip addresses are shunned yet.
I want to block 10.0.0.1 and 192.168.1.1 but my router says invalid domain so if will the guess network be able to go to page 10.0.0.1 and 192.168.1.1 even though I don't block it? I have a bypass account but don't want anyone else to access 10.0.0.1 and 192.168.1.1. Also can you tell me some proxy sites I can block?
