Netgear RP114 Router doesn't work well with Qmail POP daemon?
I recently have a user reported me the following: I recently installed a Netgear RP114 Router, to provide multiple computers access to the internet via a single cable modem from ATT. Since then, my Eudora email program encounters some sort of 30 second delay when attempting to retrieve email from any of my awit.com accounts. The status display of the process shows Logging into POP server for upwards of 30 seconds, before continuing. Once it actually starts downloading email, it proceeds as quickly as it always has. None of the other five email POPs I deal with have this problem. Do you know of anything that I can try to improve this performance? I first asked him where these five POP boxes are hosted, and then I telneted to port 110 of these five places, and got the following info: popd.accesscom.com QPOP (version 2.3) pop.vitac.com DPOP Version 2.4a venus.he.netQPOP (version 3.1.2) holzheimers.com POP3 holzheimers.com v4.47 server cihost.com POP3 localhost v4.47 server I then asked him to use telnet to port 110 to our POP server, and he still got the delay. So, I am quite sure it's most likely caused by the Netgear RP114, although I don't see any reason why this is so. The following is from the init script of our POP server. The -R is used to turn off identd, a typical cause of delay. But he got the delay with the Eudora client and with the command line telnet client regardless. tcpserver \ -v -R -x $RULESDIR/pop3.cdb \ 0 pop3 qmail-popup $HOSTNAME \ $checkpassword qmail-pop3d Maildir 21 \ | $setuidgid qmaill $tai64n 21 \ | $setuidgid qmaill $tai64nlocal \ | $setuidgid qmaill $multilog s${LOGSIZE} n${LOGNUM} \ /var/log/pop3d I am quite puzzled at this moment. We don't have a Netgear RP114 router handy, so I wonder whether anyone has experienced this and has insight into why this symptom is there. Any hints/tips are appreciated. We use qmail 1.03.

So, I am quite sure it's most likely caused by the Netgear RP114, although I don't see any reason why this is so. A common cause of this can be your POP server taking a long time to resolve his IP address into a name, and possibly his name back into an IP address. If the RP114 is doing NAT or acting as a proxy, he could be connecting from a different IP address than before. To test this, when he is connected, use lsof(8) or fuser(1) to find out what address he's coming from. Then try using whatever name lookup tools you have at your disposal (probably nslookup came with your OS) to look up his IP address, then again to look up the resulting name. If either step is slow or fails, there's your problem. Otherwise, the way I usually diagnose these things is with strace(1) or truss(1) attached to the tcpserver process. This only works if it's a pretty slow day, or you have him connected to a test server of some kind; otherwise there's too much background noise. Good luck! --ScottG. [...]

Re: Netgear RP114 Router doesn't work well with Qmail POP daemon?
I had a similar problem however my resolve to it was to take an *OLD* 286 I had laying around install a fairly bare installation of Linux on it and installed the DNS service. Then I put that online behind my firewall and added it's IP for port 53 to my NAT/Firewall and assigned it as the primary DNS server for my qmail machine. That resolved everything... However I don't know how many of ya out there have old 286 machines just laying around but you can use any machine you want you can even install bind on the qmail machine itself the only reason I didn't was I did not want the load of the DNS service on that machine.

Re: Netgear RP114 Router doesn't work well with Qmail POP daemon?
Well if the problem is name resolutions, why not just install bind on the machine itself (in a caching-only configuration)? Then make it listen only on 127.0.0.1 and make this the primary resolver for the machine. w On Mon, Jul 09, 2001 at 11:32:53AM -0700, James Stevens wrote: I had a similar problem however my resolve to it was to take an *OLD* 286 I had laying around install a fairly bare installation of Linux on it and installed the DNS service.

Re: Netgear RP114 Router doesn't work well with Qmail POP daemon?
I initially thought about it. But upon reviewing the user's report (see the underlined part) I ruled that out. He clearly said that he had his cable modem for a while, and before he got his Netgear RP114, he didn't experience any symptom. That means the reverse lookup was fine with his connection Thanks for the suggestion however.. Chin Fang [EMAIL PROTECTED] could be reverse DNS checking... -davidu I recently installed a Netgear RP114 Router, to provide multiple computers access to the internet via a single cable modem from ATT.

Re: Netgear RP114 Router doesn't work well with Qmail POP daemon?
Yes you could do that unless your parnoid about things.. Just make sure you tell your NAT/Firewall which IP to allow inbound outbound connections on port 53 to. In that case it would be that machine. The whole slowdown in my case was a stupid mistake of not mapping port 53 in the first place but even after mapping the port I found much more performance when I added the DNS server into the loop. Might be a old computer but it don't need to be powerfull to do it's job .. Just needs memmory which it has 128megs which was tough to find in the old 32pin memmory (shesh - don't even ask) BTW, this is for my office pop3/imap4 services not my outgoing mail services. My outgoing mail servers have 3 deddicated DNS servers which are housed on newer 650mhzPIII's with lotsa memmory and yes still using bind (yeah, yeah I know djbdns) --JT - Original Message - From: Will Yardley [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, July 09, 2001 1:30 PM Subject: Re: Netgear RP114 Router doesn't work well with Qmail POP daemon?
