RE: [Wlug] Newbie to mailing list- Issue with the generation of graphs in redhat 6.2

Hi Tim, Thanks for the reply.

Routing problem -can I believe the ISP tech? #2
by Richard Goodman 03 Nov '02

03 Nov '02

My apologies for the HTML, it was not intentional. I was trying to make part of the email more (not less) readable. I've changed options so hopefully it will never happen again. ======== I just brought up my fourth RH7.3 server Friday afternoon (one of two RH7.0 servers that had been hacked-new hard drive and software). I then went home and spent a couple of hours connected to it with ssh on a workstation connected to my home RH7.3 server. When I went to rerun a slightly modified (open ports for ftp and internal dhcp twiddling) ipchains firewall I lost the connection, and, more than 16 hours later, don't have it back. Other relevant details. (let's call the servers Home and EFO) Home was the other hacked server, and was formatted and rebuilt last weekend. Home and EFO are on the same ISP and each has a block of 4 static IPs. The blocks share the first 18 bits of their IP#s. Home could connect to EFO last night Home now cannot connect to EFO via ssh, or access its web site. Pings are disabled on all my servers - so I can't do that test. EFO network workstations can browse the web; I can ping out from the EFO linux box or workstations, and can ping EFO's Cisco 678 router from its Linux box EFO workstations cannot access Home websites (but I had not tried this before since rebuilding EFO Linux box Home Cisco 678 cannot be pinged from Home Linux box (!) or EFO (Linux or workstation), but can be pinged from my office (Linux box on other ISP). >From my office workstation I can also ssh to EFO and access EFO website (which in fact I uploaded to the new server from my office today). Does this discount the possibility of a firewall issue? I spent countless hours talking to the ISP (Qwest) tech support, and over an hour with a senior tech who had some Linux knowledge, and he claims that it must be a configuration issue on one or both of my Home and EFO Linux boxes, since: He can login to both my Cisco routers and ping the other router - he claims this proves its not a Qwest routing problem. If he's right I'm still puzzled by two things: a) Why could I connect from Home to EFO for two hours last night, no problems? b) Why can't the Home Linux box ping the Cisco 678 directly connected to it? I knew nothing about routing before today - here's the Home routing table: route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface xxx.yyy.28.48 0.0.0.0 255.255.255.248 U 0 0 0 eth0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 xxx.yyy.28.54 0.0.0.0 UG 0 0 0 eth0 I tried the following but still could not access EFO (added just the EFO IP#, not the network block: #route add -host xxx.yyy.26.57 dev eth0 # route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface xxx.yyy.26.57 0.0.0.0 255.255.255.255 UH 0 0 0 eth0 xxx.yyy.28.48 0.0.0.0 255.255.255.248 U 0 0 0 eth0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 xxx.yyy.28.54 0.0.0.0 UG 0 0 0 eth0 Is this enough if to decide if the tech is right or crazy? Any suggestions - I still can't access Home from/to EFO. Dick

RE: [Wlug] Looking for networking information

I found that http://www.practicallynetworked.com/ as a good site with review on DSL/Cable routers and home wireless equipment. www.homepna.org was another good site for home networks. But if you were looking at basic information such as installing NIC card and Ethernet Basics. Microsoft Press has a Network book; Cisco Press has a Network book. Both book are the basis for each's Cert Exam Curriculum.

ticked at netgear
by Wes Allen 03 Nov '02

03 Nov '02

Hi gang, I've got a ma401 card from netgear. It worked beautifully under linux (better than in windows even). Today I switch on my laptop, and I no longer get a link to my network with the card. I figure I must've had a power glitch and my firewall isn't giving out dhcp address, so I restart it. Still no link. I check the settings of my wireless router, all good. I boot my desktop to see if my usb wireless card works, it does. None of my settings on my laptop have changed, I checked. I tweak with iwconfig until my hands are sore, no luck. So I finally call netgear because I figure that it is a hardware issue and I need to send in the card to have at least the antenna replaced. Tech support says, "I'm sorry but we can only trouble-shoot on windows so we can't help you." I tell them, "It's not a software issue, nothing has changed with my software from last night, everything is the same, the card is not picking up the link from the router, it's not functioning, it's a hardware issue..." They say, "But we need to troubleshoot in windows." I say, "Look, I've turned encryption on and off, I've tried different modes, I've tried different channels, I've turned rts and frag on and off [note: now it's not accepting values, another clue that this is a hardware problem]. Nothing works, your card is broken and I want to send it in." I'm told to hold. "I'm sorry, we cannot help you. We need to troubleshoot in windows." I slam the phone on the reciever so hard I think I nearly break it. Now I am pissed, and I still have a broken card. Does anyone else have any history with wireless antennas not working all of the sudden? This card hasn't even been out of the house, I leave it here when I go out for crying out loud! My next attempt will to disable encryption and go back to wvlan_cs to see if that jogs this thing. But I truly think it's hardware; nothing, NOTHING, on my laptop changed, I didn't even turn it on this morning!

2 goddamn megabyte message
by Keith Wright 02 Nov '02

02 Nov '02

Somebody just sent a 2 Megabyte message to this mailing list, I think. I don't even know who sent it, because I got tired of watching it download and telnet'ed into my pop server to delete it totally unread. Since I don't know who you are you are safe (from me at least) if you never do anything like that again. Can the mailing list software be configured to throw any message more than, say, a generous 200K, into /dev/null and reply to the sender with a polite message about his mother and a baboon? Thank you very much. -- Keith

DNS Resolve from the Internet
by jose sanchez 02 Nov '02

02 Nov '02

Hello: Please help me get this straight. I am confused. I have a dnscache running at home on a DMZ network. I would like to know if I can have friends on other networks (in the Internet) to use my server as their resolver server? I have a firewall in place but, I'm directing all the udp traffic to port 53 to my dns-server; also my dnscache server is accepting connections from those networks ip's. Can I do this or do I need to register ($$$$$) a the dns-server? Thanks in advance for your help.... ===== "An ounce of gold cannot buy an ounce of time." - Anonymous www.whmicro.com __________________________________________________ Do you Yahoo!?

Sendmail 8.11.6 (was building RH7.3 after hack)
by Richard Goodman 31 Oct '02

31 Oct '02

I spent four hours on Google last night about this problem. Saw reports of the same messages, but not the same situation. SUMMARY: 3 separate servers upgraded from RH7.0 to RH7.3 - all can send/receive mail locally and to/from the outside world EXCEPT for/from each other - which was not a problem under RH7.0. Do not believe there are errors in config files, particularly /etc/mail/local-host-names, and I have read the part of the sendmail FAQ about "mail loops back to me" and it DOES NOT APPLY in this case. I've been through what sendmail documentation I can understand - can someone tell me what has changed somewhere prior to or at 8.11.6 which shipped with RH7.3 that might cause this? I have another identically hacked RH7.0 server which I hope to rebuild/upgrade tonight - it will be interesting to see if all FOUR servers have the same problem. I'm losing mail which is supposed to be forwarded between these servers. Dick
