For some reason my DNS servers aren't able to resolve certain names. Most names resolve fine there are just a few that don't work. Nslookup doesn't work either of course, and curiously neither does "whois".
Here's an example:

I dual boot XP and FC14 and have 2 routers. I can connect and ping one of these routers when I'm in FC and I have an IP address I just can't load any websites. When I connect to the other router (my main router) it works fine. When I boot into XP and connect to the problem router I can load pages fine. It's only when I'm on FC14 and connect to the problem router that I can't load pages even though I have an IP and can ping around.

For each write, I would like to know the time, date, process id, user, file position, byte count, and the data written.
I could use this with a script to replay the writes to a backup of the original file, and reproduce the file contents as they were at a point in time.
I need to trace/track email activity in my ubuntu server, normal i use this command tail -f /var/log/mail/mail.log, more or less. But the problem i am facing is that it take a long time to go through the entire log as my server recieves thousands of emails per day. is the a code that i can use to search email in the log, for instance need to find perfectpol@mycompany.com in the mail log.
Secondly; if there is an email that is blocking others on the queue how can it be remove or forced to go the mailbox. or to view its contents in order to decide whether to remove it or not.

I've got a few systems which forward ports to one another all over the place, and somewhere along the line a port forward fails. I want to trace the route of a connection on a specific port to see where the connection hits a wall, to see what system is causing the problem. I've tried `tracetoure -T -p <port>` but it doesn't output anything about the ports it hits, stops when it hits the address I supplied even though it is forwarded elsewhere, and there doesn't seem to be a verbose mode. interstingly, if I specify a different source port via the '-s' option, the trace keeps hopping to * * * * and never get anywhere (at least to 27 hops then I CTRL+C)

In the past week or so I've noticed some weird network behaviour. I find accessing some sites such as Amazon, Paypal, and Bigstockphoto really slow. Sometimes the page will not load at all. Other sites are fine. The problem sites are not a problem for others on my LAN at home. When I try to open the problem sites, I can see in Firestarter blocked connections coming from 2.1(8/9).xxx.xxx on various ports such as 36007. This only happens for the problem sites. I attached a typical output from firestarter.
This happens with Firfeox or Chrome. Using Ubuntu 10.10
OS : CentOS 5.3 64bit How to trace incoming and outgoing network traffic for a give user? User 'A' logs in to the system and does various network connectivity As root user need to find what are the outgoing and incoming connection that are related with user 'A'. basically need to check the connection flow. netstat will show ESTABLISHED, LISTEN etc.. need something like tcpdump
Eg:- --user option for tcpdump tcpdump -vv -nn -i eth0 host 10.200.2.1 and tcp dst port 8080 --user A Can someone tell me any tool which can do such thing? Even if it can show the process ID of the client application which is trying to establish network connectivity will do.
I've troubles getting my new Sweex wireless 300N USB adapter to work. Tried searching in several directions (see closed thread). Further investigations shows however it is caused by the NDISGTK wrapper for Windows drivers. Can anyone tell me whether Sweex is shipping a faulty driver (it is the latest available) or it is a fault in ndisgtk? Or maybe I'm doing something stupid myself, which I do not find completely imagenary below some more detailed information on my findings: Started with network off and examined the networkstatus

View 2 Replies View RelatedI have set up a nis slave server on Fedora 14. It was set up on a laptop so that the user can log in when he is at home (no NFS, local home dir). However, whenever the eth0 is disconnected, ypbind fails.
I have tried the same setup on a RHEL 4 (configured it as a slave server) against the same master nis as on the Fedora 14. Disabling eth0 on it however does not fail ypbind.
I have a server with 8GIG of ram and a quad-core q9550 CPU and 500GIG of hard-disk space, and 100Mbps net connection.I have separated it into 3 parts of 2 Gigs of ram each, by virtualization, so there are 3 VPSes. The problem is that the one of the VPSes (created) with centos and WHM/cpanel would go down very often, as many as 60 times per day!I asked one of my friends to have a look at it, and he told me that Tomcat was the reason.Things got a little better (ask me what I changed about Tomcat?!) and after that the server would go down only about 20 to 30 times per day.I asked the friend again, and he told me that the CPanel integrated antivirus would cause the high load periodically.(Ask me again, what did I change?) And after that the server would go down only about 4 to 10 times per day.Now, as far as I can tell, there is nothing more that would/should cause the server to go down.
About 30 minutes ago, before writing this post, the hosted sites were unavailable again, for about 30 seconds.I checked the load through ssh and I saw that the load is 3, so I went to the main server and checked the VPS ram and noticed that only 10% of the cpu is used and only 307Mb of available RAM is used.
Everything shows that the server should be functioning OK, but it still seems to get unavailable far too often.
I used the top command and noticed that there is nothing using the cpu and the ram and all of them are 0.I used the mysqladmin proc command and again nothing noticeably weird seemed obvious at this time. I also checked the other VPSes and they were also in relatively low-resource-consumption states(I don't understand this part):Also sometimes I use the top command when the load goes high I see that all of the users, even the non visitors users site use cpu seems forexample a refreshing things or updating thing updates all of the accounts forexample mysql or so Please help me to figure out what other things might be causing these service/server high loads and unavailability.

View 2 Replies View RelatedIs there a way to prevent users of an OpenVPN service from accessing restricted sites? I know this can be done through a proxy server but through a VPN there seems to be no way of preventing traffic from accessing porn sites or other as the traffic is encrypted. I am using a VPN in the same fashion as a proxy server except that the VPN is necessary because some video sites use rtmp on port 1935, which a proxy server cannot route.

View 1 Replies View RelatedI have an odd Linux problem. Changed ISP recently -- Windows NT4 & W95 work fine. Linux has worked fine on previous ISPs, but on the newest ISP, I can connect successfully on Linux, but can only communicate w/maybe one out of 10 sites (Google, for ex.). Mostly I get "cannot connect to site". Some points:
-Linux is Slackware w/kernel build 2.4.26.
-No settings changed from Linux setup that worked fine on previous ISPs.
-/var/log/Log file says PPP connects via CHAP successfully & no problems..
-I don't see any similarity on the few sites I can connect to -- seems random.
-ISP is useless -- say they "don't support Linux".
-Using Firefox & Konqueror browsers.
